Issued to \ViLnington l-lo 1Jsi:1g Autao:·1ty
These pem1its for these closed loop injection well systems were issued with the condition
that they could use potable water only or a Environol-potable water mixture, but no post-
construction documentation existed to indicate which was used. The attached letter from
the heat pump contractor' indicates that only water was used, making these 5QW injection
well systems. Effective Febmary 1, 1997, this type of injection well is deemed pennitted
by rule and no longer requires a pennit.
On this date the record for this pennit was removed from the UICfile database, which
keeps track of injection wells that need permits, and added to the 5QWlist database,
which keeps track of injection wells that do not require permits. Likewise, the paper file
was moved to a drawer that stores 5QW injection well files.

Dear Mr. Slessor,
The closed loop field far the Geothermal project at Wihnington Housing Project was
designed to use water with no type of antifreeze necessary_ To the best of my knowledge
there was never any antifreeze solution of any kiwi used.

Dear Mr. Foster:
This is in response to your petition requesting variances
from the referenced Rules. Rule 2C .0213 (d)(l)(A) requires that
a well casing be installed which extends from at least 12 inches
above land surface to the to p of the in j ection zone. You
indicated in the letter dated September 27, 1995, and in the
modification to that letter dated October 19, 1995, that the
previously described injection well construction method would not
be possible due to the engineering design of the system.
Rule 2C .0213 (e)(l)(C}(i) requires that g rout be emp laced
in an in j ection well from land surface to a minimum -de p th of 20
feet. You indicated in the letter dated September 27, 1995, and
in the modification to that letter dated October 19, 1995, that
the previously described injection well construction method would
not be possible due to the engineering design of the system.

Variance to 15A NCAC 2C .0213
Page 2
Rule 2C .0213 (c}(l}(D} requires that an injection well be
located 25 feet or more from a water-tight sewage and liquid
waste collection facility in the case of a single-family
dwelling. You indicated in the letter dated September 27, 1995,
and in the modification to that letter dated October 19, 1995,
that meeting the minimum separation distance requirement would
not be possible due the high density of housing (and sewage
pipes) at the site.
Factors that would act to mitigate any potential problems
which could adversely affect human health and/or the effective
operation of these wells, because of not meeting the regulatory
requirements, are as follows:
1. Upon completion of drilling of each well, the
closed-loop piping will be installed and
grouted without delay.
2. The annular space of each well will be grouted full
length from bottom to top with a high-solids bentonite
slurry, as described and illustrated in the permit
application dated September 27, 1995. The grout will be
emplaced in a continuous operation through a pipe lowered
to the grouting point, as'described in the letter dated
September 27, 1995. This ~construction method will
provide an adequate seal and prevent the vertical
migration of contaminants by way of the borehole.
3. The fluid to be circulated in the vertical closed-loop
heat pump system will be potable water or a propylene
glycol/ potable water mixture.
Based on my review of the available information and
recommendations by our staff, it is my finding that the combination
of factors specified above are sufficient to satisfy the conditions
for approval of variances from 15A NCAC 2C .0213 (d)(l}(A), from
15A NCAC 2C .0213 (e}(l}(C}(i), and from 15A NCAC 2C .0213

STANDARDS, Title 15A NCAC 2C.0200, Criteria and Standards Applicable to
Injection Wells
1002/1004 S. 15TH STREET, HILLCREST APARTMENTS
WILMINGTON,NC
As a result of my conversations today with Ms. Karen Harmon of your office, I am submitting a
modified variance request for the subject units. This modified variance request adds a third
request for variance for emplacement of grout in bore holes.
(1) We request a variance to 15A NCAC 2C.0213 (d)(l)(A) which requires that a well casing be
installed which extends from at least 12 inches above land surface to the top of the injection
zone. The injection well construction criteria described in Rule 2C.0213 (d)(l)(A) will not
be possible due to the engineering design of the vertical closed-loop heat pump system.
(2) We request a variance to ISA NCAC 2C. 0213 (c)(l)(D) which requires a minimum
horizonal separation of 25 feet between a well and a water-tight sewerage and liquid waste
collection facility in the case of a single family dwelling due to the housing density of the site.
As the fluid is contained within a closed loop, the risk of cross-contamination is minimal.
(3) We request a variance to 15A NCAC 2C. 0213 (e)(lXC)(i) which requires emplacement of
grout from the land surface to a minimum depth of20.feet. The injection well construction
criteria described in Rule 2C.0213 (e)(l)(C)(i) will not be possible due to the engineering
design of the vertical closed-loop heat pump system.
Mr. Bob Cheek

October 19, 1995
Each well will be drilled 100 feet deep. The grout pipe method recommended by the International
Ground Source Heat Pump Association (IGSHP A) will be followed. The closed-loop ground
heat exchanger (GHEX) loop is immediately inserted into the bore hole . Grout is placed in one
continuous operation by pumping, beginning at the bottom of the zone being sealed and continued
until it appears at the ground surface.
Grouting is an important aspect of the installation of a GHEX when used with a ground-source
heat pump system. Not only will it provide the proper heat transfer between the GHEX and the
ground necessary for the most efficient operation of the ground-source heat pump syste~ but it
will also provide groundwater protection.
This method of construction will prevent any fluids from entering the injection well at the surface
because all well heads will feed into a closed loop system that is underground and out of view
from the system users.
Please contact me at [phone] if you have questions or need additional information.
Sincerely,

SUBJECT: VARIANCE TO NORTH CAROLINA WELL CONSTRUCTION
STANDARDS, Title 15A NCAC 2C.0200, Criteria and Standards Applicable to
Injection Wells
1002/1004 S. 15TH STREET, HILLCREST APARTMENTS
WILMINGTON,NC
(1) We request a variance to 15A NCAC 2C.0213 (d)(l)(A) which requires that a well casing
be installed which extends from at least 12 inches above land surface to the top of the
injection zone. The injection well construction criteria described in Rule 2C.0213 (d)(l)(A)
will not be possible due to the engineering design of the vertical closed-loop heat pump
system.
(2) We also request a variance to 15ANCAC 2C . 0213 (c)(l)(D) which requires a minimum
horizonal separation of 25 feet between a well and a water-tight sewerage and liquid waste
collection facility in the case of a single family dwelling due to the housing density of the
site. As the fluid is contained within a closed loop, the risk of cross-contamination is
minimal.
Each well will be drilled 100 feet deep. The grout pipe method recommended by the
International Ground Source Heat Pump Association (IGSHP A) will be followed. The closed-
loop ground heat exchanger (GHEX) loop is immediately inserted into the bore hole. Grout is
placed in one continuous operation by pumping, beginning at the bottom of the zone being
sealed and continued until it appears at the ground surface.
Mr. Bob Cheek

September 27, 1995
Grouting is an important aspect of the installation of a GHEX when used with a ground-source
heat pump system. Not only will it provide the proper heat transfer between the GHEX and the
ground necessary for the most efficient operation of the ground-source heat pump system, but it
will also provide groundwater protection.
This method of construction will prevent any fluids from entering the injection well at the
surface because all well heads will feed into a closed loop system that is underground and out of
view from the system users.
Please contact me at [phone] if you have questions or need additional information.

each fusion application. Rags shall be free of any cleaning solvents, grease or dirt.
PART 3-EXECUTION
3 .1 Inspection:
General: Examine areas and conditions under which ground heat exchanger systems are to be
installed. Do not proceed with work until unsatisfactory conditions have been corrected in a
manner acceptable to manufacturer's recommendations. Any leaks shall be "cut-out'' and repaired
in accordance to manufacturer's recommendations.
3.2 Installation of Basic Identification:
3 .2.1. General: Install mechanical identification of vertical bore holes and connecting headers.
3.3 Boring, Trenching, and Backfilling:
General: The vertical holes of bores shall be 200 feet deep and shall be clean (no casing) and of
sufficient diameter to facilitate the installation of the U-tube assembly. The bores shall be
backfilled with appropriate material to assure pipe contact and meet local and state requirements
for sealing. The bores shall not contain large, sharp, or jagged rocks or debris. Reasonable and
prudent care shall be taken during installation and backfilling in order not to crush, cut, or kink the
pipe.
The horizontal ditches for the ground heat. exchanger header piping may be dug with a chain type
trenching machines or a backhoe. The header piping shall be buried a minimum of 36" deep. If
the soil contains sharp -rocks, dig the trench 611 deeper than required and install a base of 61, of
suitable backfill (screened soil from the job site) before placing the pipe. After the piping is
installed, tested, flushed, purged, inspected, approved while still under pressure, backfill with a
suitable backfill for 6" and then finish backfilling with job Bite material. Coordinate the laying of
the header piping with existing utilities, new mechanical and electrical utilities. Prepare.
dimensioned drawing of the complete ground heat exchanger piping system before backfilling.
3.4 Installation of Piping:
3.4.1. General:
3.4.1.1. Install piping in accordance with manufacturer's written instructions.
3.4.1.2. The pipe and fittings must be joined using the butt or socket fusion process. No other
method is acceptable. The vertical loop takeoff tee fittings may be made using tee's or the saddle
fusion process on header piping 1-1/4" and above. Exercise extreme caution to completely remove
the cutout on saddle tees. Bell reductions shall be used at all pipe reductions to eliminate trapped
air.
3.4.1.3. Use reducing socket tees when fabricating Socket type reducing headers. Consult with
manufacturer for available fittings and fabricated headers.
3 .4.1.4. A void sharp bends in piping. Consult pipe manufacturer for minimum bend radius.
Install elbow fittings for bends which require tighter radii than manufacturer recommends. Use
only continuous pipe in sharp bends.
3.5 Testing and Cleaning
3.5.l Cleanliness:
During installation, trash, soil and small animals Shall be kept out of the pipe. Ends of the pipe
shall be taped or capped until the pipe is joined to the circuit.
3 .5.2 Flushing the Ground Heat Exchanger:
Before connection of the plastic ground heat exchanger .loops to the header lines, each loop shall
be flushed thoroughly and left filled with clean water. If the loop is not going to be joined to the
header at this time, it should be taped or capped.
3.5.3 Pressurizing:
Each U-fitting assembly (loop) shall be water filled and pressure tested to 100 psi prior to insertion
into well bore. th<:: complete system shall be water filled and pressure tested to 100 Psi prior to
backfill of the trenches. Every weld shall be visually and physically examined.
3.6 Flushing and Purging:
3 .6.1 General:
Before backfilling the trenches all systems shall be flushed and purged of air and flow tested to
ensure all portions of the heat exchanger are properly flowing. A portable temporary purging unit
shall be utilized and shall consist of the following (See OSU/IGSHPA CL/GS Heat Pump
Systems:
Installation Guide. Figures 7.7 & 7.8, pages 152 & 153)
1. purge pump -high volume & high head,
2. open reservoir,
3. filter assembly with by-pass,
4. flow meter,
5. pressure gage,
6. connecting piping, and
7. connecting hoses.
Using the purging unit described above, flush and purge each ground heat exchanger system until
free of air, dirt, and debris. A velocity of 2 ft/sec. is required in all pipe sections to remove the air.
The flushing and purging operation should be conducted with the water source heat pump piping
isolated with shut off valves. After the ground heat exchanger is completely flushed of air and
debris open the isolation valves and pennit circulation through the heat pump portion of the
system until the entire system is flushed and purged.
Utilizing the purging unit conduct a pressure and flow test on the ground heat exchanger to ensure
the system is free of blockage. If the flow test indicates blockage, locate the blockage using
manufacturers recommendation, remove the blockage, then repurge and conduct the pressure and
flow test again until all portions of the system are flowing. The flow test must be observed and
approved by the Engineer or his designate. before the systems can be backfilled.

The Geothermal
Principle
The basic principle of a geothermal system is
to transfer heat from a building to the earth in the
cooling mode, or from the earth to a building in the
heating mode. Water 1s used to carry this heat either by
circulating through an underground closed piping
loop or by directly pumping ground water. Using this
water as a source, WaterFurnace units can transfer
heat into or out of indoor space, to provide year round
comfort.
WaterFurnace geothermal systems achieve
extremely high levels of efficiency because electricity is
used only to move heat, not to produce it. Using a
typical Spectra Series unit, one ldlowan hour of
electricity can move 4-5 kilowatt hours of heat. And
most systems include a hot water assist package which
diverts a portion of the heat to provide Iow-cast hot
water anytime the unit is running.
The WaterFurnace
Advantage
No conventional heating and cooling system
can match the exceptional comfort provided by the
WaterFurnace Spectra Series. In heating, supply air
temperatures are much warmer than with air source
beat pumps, and there is far less cycling compared to
fossiI fuel furnaces, which creates a more constant
indoor temperature. In cooling, lower sensible heat
ratios provide better dehumidification than high
efficiency heat pumps or air conditioners. Spectra
units are also extremely quiet clue to well engineered
rotary, scroll, or reciprocating compressors, mulb-
speed fans, and heavy duty insulated cabinets.
Spectrasystems can provide heating, cooling
and hot water fxom a single factory -assembled unit.
There's no outdoor equipment to install or service, no
field refrigerant evacuation or charging, no flues or gas
piping to install, and only one unit to wire.
With ARI-rated COP's over 4.0 and EER's over
1S, the Spectra Series heating and cooling efficiencies
are among the highest available, which means low
operating costs for customers. And compared to other
geothermal units, Spectra efficiency combined with its
wide operating temperature range, usually means earth
loops can be shorter.
Geothermal technology is environmentally
advantageous —it can help solve global warming and
ozone depletion by using natural energy removed from
Spectra Advantages
• Low operating costs
• High value

• Comprehensive warranty
the earth instead of energy that must be artificially
produced, generated and transported. Spectra units do
not contain any CFC's and use far less refrigerant than
heat pumps or air conditioners, and they are factory
sealed to prevent leakage.
The initial cast of a geothermal system is
usually higher than a conventional system. however,
when operating and maintenance costs are consid-
ered, it provides the lowest life cycle costs. In new
construction, monthly energy savings typically exceed
the increased loan payment, so cash flow is positive
from the start. in retrofit, a buyer who purchases with
cash usually realizes a return on investment well above
certificate of deposit rates. With equipment life
expectancies exceeding 20 years, and earth loop
warranties exceeding 50 years, a WaterFurnace system
Is a lasting investment.
Electric utilities, recognizing the dual
advantages of high efficiency and low peak demand,
often provide incentives to install geothermal systems.
The WaterFurnace
Approach
To choose the right geothermal system, you
must evaluate many application factors for instance;
ground waxer availability and quality, to op installation
costs, available land area, sub -soil conditions, local
codes, owner preferences, etc.
Authorized WaterFurnace Dealers have the
expertise and software to determine the best type of
system. In many locations there are Authorized
WaterFurnace Geothermal Services Contractors to
assist in this process and install the underground loop.
Common system choices are shown on page 3.

Closed Loop Systems
Closed loop systems consist of an underground network of
sealed, high-strength plastic pipe "heat exchangers." When cooling
requirements cause closed loop liquid temperatures to rise, heat is
dissipated into the cooler earth. Conversely, if space heating demands
cause the loop temperature to fall, heat is extracted from the earth.
Closed loop systems utilize small low-wattage pumps to circulate the
liquid, which is usually a water/antifreeze solution. The loops are closed
and sealed, so they do not require a ground water supply or drain, and
they are not subject to mineral build-up.
Closed loops can be installed in a horizontal or vertical
configuration, or submerged in a pond or lake. All three alternatives,
when designed properly, operate with similar efficiency.
Horizontal loops are often conside;;r;hen adequate land
surface is available. The pipes are placed in trenches, excavated to a
depth of 4-6 feet by a backhoe or chain trencher. Anywhere from 1-6
pipes are installed in each trench, depending on design. Multiple pipe
configurations are used to conserve land space and reduce overall loop
costs. Trench lengths range from 100-400 feet per system ton. Trenches
must be spaced from 6-10 feet apart.
Vertical loops are the ideal choice when available land surface
is limited. Drilling equipment is used to bore small-diameter holes from
75-300 feet deep. Two pipes joined together with a U-bend fitting are
inserted into the vertical bore. Bore hole depth ranges from 125-200 feet
per system ton. Bores must be spaced 10-15 feet apart.
Pond (Lake) Loops are very economical to install when a body
of water is available, because excavation costs are virtually eliminated.
Coils of pipe are simply placed on the bottom of the pond (lake). In
most cases, 1/4 to 1/2 acre of water surface, with a minimum depth of 6-
8 feet, is required . •
GEOLINK® high density polyethylene plastic pipe is used for all
closed loop installations. Pipe connections are heat fused to form joints
that are stronger than the pipe itself. WaterFumace GEOIJNK pipe is
warranted against defects in materials and workmanship for 55 years .
When installed by an Authorized WaterFurnace Geothennal Services
Contractor, the entire piping system can be warranted against leaks due
to manufacturing defects or joint failures for 55 years.

Open loop systems utilize ground water as a direct energy
source when good quality well water is available at a reasonable
pumping depth. A well must have enough capacity to provide continuous
1.5 GPM per system ton during peak operation. And a good water
discharge system must be available-ditches, field tiles, ponds and
streams are the most common. In ideal conditions, an open loop
application can be the most economical type of geothermal system .

FOR GROUND -COUPLED APPLICATIONS
Vanguard GEO-PRODUCTS provide installers with the most versatile pipe and fittings package available in the
ground -coupled heat pump industry. Thousands of miles of Vanguard GEO-BLACK high density polyethylene
pipe have been installed in systems across America, No other company offers more choices of pipe sizes,
fusion fittings, and accessory equipment for the ground -coupled markat than Vanguard Plastics.
The products contained in this catalog are manufactured and intended only for their specific uses in non -
potable applications involving the transport of water, water and glycol, water and GS-4 HTF, or other aqueous
liquids shown not to adversely affect the performance of GEO- BLACK pipe and fittings.
All products shown in this catalog are designed and made to meet written national standards. To find out if
Vanguard products are approved for your applications, contact the Vanguard representative or applicabie code
enforcement bureau in your area,
It is important to know the advantages and drawbacks of the various types of fittings and realize, as with all
piping materials, failures are most likely to occur at the fitting joint.
Polyethylene is not resistant to all chemicals. Gasoline, oil and hydrocarbons can damage this material, Strong
acids and oxidizing agents, such as excessive levels of chlorine, must be avoided.
Polyethylene piping and components must be installed in accordance with good plumbing practices, applicable
code requirements, and current installation instructions provided by Vanguard Plastics, Inc. upon request. It is
the responsibility of the contractor or installer to determine that the selection of polyethylene pipe and other
components are the proper ones for the intended application, and that all installers observe installation
Practices recommended by Vanguard Plastics, Inc. If there is any doubt whether water conditions or other
conditions likely to be encountered in the intended application may be harmful to PE, call a Vanguard technical
representative at 1-316-241-6369.

GEO-BLACK HDPE POLYETHYLENE PIPE
GEO-BLACK piping is intended and recommended for use in ground-couplea applications involving the
transfer of heat energy between the earth and water, water and glycol solutions or other liquids shown not to
adversely affect polyethylene's performance. GEO-BLACK is manufactured from PE3408 resin with a cell
classification of PE345434C and is specified in ASTM I}3350 and is specifically designed to be connected
with IPS-Op, PE3408 socket meat fusion fittings. It is also acceptable to connect GEO-BLACK with appropri-
ate butt fusion fittings and equipment.
GEO-BLACK rneets applicable ASHRAE, ASTM and IGSHPA national standards. GEO-BLACK can withstand
continuous use at temperatures as nigh as 100 degrees F and intermittent use up to 120 degrees F GEO-
BLACK is flexible, resistant to electrolysis, corrosion, ultraviolet light degradation, and many chemicals.
Through the use of socket heat fusion, user benefits include quickness and ease of installation.
Limitations of GEO-BLACK tubing include the following:
■ Install in accordance with IGSHPA recommendations, applicable code requirements and current
installation instructions provided by Vanguard Plastics.
■ Do not expose to direct flame or temperatures, including internal water temperatures, which continu-
ously exceed 100 degrees F
■ Limit water pressure to the maximum limitation marked on the tubing.
■ Vanguard GEO-BLACK must be installed and inspected in accordance to ASTM-d2774. Consult IGSHPA
recommendations for any variations in these backfill procedures.
GEO-BLACK POLYETHYLENE FUSION FITTINGS
GEO-BLACK fittings are designed for use in ground -coupled water source heat pump systems where the
quality and durability of polyethylene is desirable. GEC+ -BLACK heat fusion fittings are to be installed only by
persons certified in fusion either through the Vanguard Heat Fusion Certification Program or IGSHPA certified
instructions. Fittings are manufactured from the same Nigh -density PE 3408 polyethylene resin as GEO-
BLACK ground -coupled piping.

A GUIDE FOR INSTRUCTION
IN VANGUARD
SOCKET HEAT FUSION
This publication has been prepared to provide general
guidelines in joining pipe and fittings using the Vanguard
Socket Heat Fusion System. The publication explains each
step of proper socket fusion, and shows the procedures for
socket fusion. Permanent field installation shall be done .. .
only by, or under the supervision of, operators properly (
trained and certified by an authorized instructor of the .
Vanguard Socket Heat Fusion System.
The procedures detailed herein are applicable to all PB2110
pipe and fittings manufactured according to ASTM D-3309
and D-2666 specifications, and PE3408 pipe manufactured
according to ASTM D-3035 and D-2447 specifications.
Socket Fusion hwedures
1 THE SOCKET HEAT FUSION TOOL
MUST BE CORRECTLY PREPARED
■ The correct socket faces must be securely attached to the heating body of the
tool. (Do not over tighten) (see Fig. 1).
• The socket faces must be in good condition.
■ Use an adequate power supply (120V) and adequate power supply cord.
• Use a power supply not in use with other tools. Single face heating toots draw
400 watts, while double face tools draw 500 watts. Allow a minimum of a 5
Socket Fusion Tools
Figure 1
ZSOCKET FACES MUST BE CLEAN AND
HEATED TO THE PROPER TEMPERATURE
■ Socket face surfaces absolutely must be wiped with a clean, DRY, cotton rag
immediately after each fusion.
■ Socket face temperatures are critical and must be maintained throughout the
fusion process to assure an adequate bond, especially in cold weather.
► Heating tool thermometer indicates internal tool head temperatures, NOT the
socket face surface temperatures.
■ Socket face temperatures MUST be 500 to 525 degrees F This is especially
critical in cold weather.
■ Check the socket face surface temperatures OFTEN with a pyrometer or
temperature indicating crayons (available from Vanguard). Use only temperature
3 PIPE ENDS AND FITTINGS MUST BE PROPERLY
PREPARED FOR FUSION
• Pipe must be cut SQUARELY with a tubing cutter designed for plastic pipe.
■ Thoroughly wipe and remove all foreign material at the joining surfaces with a
clean, SLIGHTLY damp rag.
• Inspect each and every fitting for out-0f•roundness or damage, and wipe
clean. Check inside, pipe for contaminants or obstructions.
■ INSERT STIFFENERS supplied with 112" CTS and 3/4" CTS fittings must be

Socket Fusion Procedures
4 USE A PROPER DEPTH GAUGE AND
COLD RING
After the pipe end and fitting sockets have been cleaned and inspected, place
the depth gauge on the pipe end {see Fig. 4}' The depth gauge its used as a
guide for positioning of the cold ring. After placing the depth gauge on the pipe,
hold the gauge firmly in place and clamp the cold ring around the pipe, flush
against the depth gauge (see Fig. 5).
Using the depth gauge/cold ring combination assures that the heated pipe and
fitting will join at the proper depth, prohibiting the pipe from either penetrating
too far into the fitting, creating a flow restriction, or failing to penetrate the fitting
deeply enough for adequate joint strength, The cold ring also helps keep the
pipe round while it is being heated.'
PIPE END AND FITTINGS ARE NOW READY FOR HEATING.
• special insert strlteners are needed an all GIs " or 114" SDR 11 polybutylene tuslorrs and should be
inserted before placing the depth gauge on the pipe end-
5 PIPE AND FITTING ARE
SIMULTANEOUSLY HEATED
• Grip the pipe behind the cold ring (see Fig. 6).
• Push the pipe end (with Gold ring attached) squarely onto its socket face while
simultaneously pushing the fitting over the opposite socket face at the same
rate of pressure.
• The cold ring should BARELY TOUCH the leading edge of the pipe socket
face and the fitting edge should be just flush with the socket face. Don't force
the fitting against the heated plate (see Fig. 7).
• Begin the timing cycle as soon as the cold ring and fitting edge are fully
inserted into the socket faces.

wind currents, etc., do not affect temperatures. Use the
FHHB heater bag during periods of delay to prevent
Pleat loss when fusing in cold weather.

6 PIPE AND FITTING ARE
PROPERLY FUSED
You must check the socket face temperatures before each fusion in cold weather
(Below 320f ). Be sure that wind currents do not affect face temperatures. Tool heat -
up time is 10 to 15 minutes under normal conditions'
■ When the Pleat cycle is complete, remove the fitting and pipe from the socket
faces with a quick, snap action.
■ Quickly (within three seconds) and WITHOUT TWISTING, push the pipe and
fitting together squarely until the cold ring is in contact with the fitting edge
(see Fig. 8).
■ Hold the joined pipe and fitting firmly together for 30 seconds (see chart), To `
release pressure before the required holding time has elapsed will cause the pipe
to "back out", resulting in a faulty fusion joint.
• Whan the holding time has elapsed, the fused joint is set enough to allow
CAREFUL MOVEMENT. However, the joint is still fresh and MUST NOT be
twisted, torqued, bent or otherwise handled roughly for 20 min. (1/20 to 11/2" )
or 30 min. (2" and 3") after the fusing process (see meat cycle charts on page 4).
FUSION SOCKET FACES MUST BE WIPED OFF IMMEDIATELY AFTER EVERY
FUSION. ALL VISIBLE MATERIAL MUST BE REMOVED.
USE CAUTION WHEN HANDLING OR CLEANING HOT FUSION IDOLS TO AVOID
BEING BURNED.

7TESTING FOR'LEAKS
After assembly, the system should be tested for leaks. All systems shall be tested
hydrostatically.
I. Test pressure small be at least equal to normal system wof king pressure (main
pressure), but NOT LESS than 40 psi and NOT GREATER than manufacturer's recom-
mended application for installation. Test duration should not be less than 15 minutes.
2. When testing polybutylene during the initial pressurization period, the pressure
indicated on the gauges will decrease due to the initial deformation of the pipe,
followed by a slow expansion. The pressure drop is dependent on ambient
temperature, system capacity and test pressure. If additional make-up water is
introduced into the system, the pressure decrease during the next two hours
would be less than the toss in the first 11/2 hours. The pressure decrease due to
pipe deformation and expansion shalt not exceed ten percent during the initial
two hours of the test period, after which the expansion shall not cause the
pressure to decrease more than three percent during the next two hour period.
3. The entire piping system is to be visually examined. Each joint shaft he
thoroughly inspected for good workmanship and leaks. If a leak is detected, the
connection or pipe shall be replaced and retested.
4. Each fusion joint shall be compression tested for a "cold fusion joint" After
proper curing time has elapsed, and while still under pressure, lightly squeeze
the pipe next to the fitting (do not apply enough pressure to squeeze the pipe
together). If a slight cracking sound can be heard while squeezing, the fitting
should be replaced and retested.
CAUTION: DO NOT use pliers which have sharp, serrated jaws which could cut
or damage the pipe.
5. Record vital information such as job sites, operator name and Vanguard certifica-
tion number, date, weather conditions and pressure test results.

SOCKET FUSION M-fWGS
Folyetbyi= soclot fiWcm requires an intesferenx fit betw= the. melted pipe
end and the fleeing socke#, so it is not possible to fit a s=kW fitting onto a pipe

SOCKET FUSION TOOLS ARE DESIGN TO PROVIDE THE PROPF.It FIT
TO PIPE AND F=G SOCKM ONLY RETFN THEY ARE HOT, THAT
IS, WEFT THEY ARE FMATED TO 500 " F. Cold tool dimensions are
important only to the tool manufacmm who must produce his tools to meet
ASTM specified hot tool dim noes. The fit of a cold tool to a pipe or a fxtang
socks wW be much looser than when the tool is hot, bamuse the tool expands
when it is hot. Further, diff=nt metals and grades of metals wWd at Metrartt
rates, so cold tool dimensions for tools from one manufacturer may differ from
those of another.
when a heated tool is brought into coated with polyethylene pipe or a fitting
socket,, it heats and melts the material so that parts can be used together. Heating
polyethylene causes the material to expand dramatically, and helps produce the
interference lit required for heat fusion.
ti
So even if a cold fusion tool fits completely ,over a pipe end, or into a fitting
socket, it does not indicate that the pipe or mming are out of tolemce, The
ONLY way to determine if a pipe or a fitting socket is dimensionally convict, is
to actually measure it against the required, ASTM Specification. A COLD

Fusion Procedures
3. Socket Faces must Be Clean And Heated To The Proper Temperature
4.
A. Use caution when hurdling or cleaning hot fusion tools.
8. Socket face surfaces absolutely trust be wiped with a clean, 4n, cotton rag iULMWjWgJy after each fusion.
C. Socket face temperamres we critical and must be maintained throughout the fusion process to assure an
adequate bond, especially in cold weather bctaw S5°F
D. The fusion cool cover should be used at all times to mainr$in temperature and protect the socket Faces.
E. Heating tool thermometer indicates internal tool head temperature, = the socket face surface temperatures.
F. Socket face temperatures must be M taAL11 for polyeutylene and 420 tg,-414 °F for
polyethylene. This is espet Ily Critical in humid. windy, and cold weather.
G. Check the socket face surface temperatures often with temperature indicating crayons. Use only
temperatstre indicating crayons which have the correct temperature label.
H. Don't Clan the socket face surfaces with a synthetic fabric (polyesters).
I. Don't rely on the heating tool temperaturc gauge to indicate face surface temperatures.
I. Don't use temperature indicating crayons on the surface of the non-stick faces where the pipe and fitting
come in contact.
K. Don't clot the socket face surfaces with a wet or damp rag. chemicals or solvents, nails, knives or other
sharp, hard objects.
L. Don't place the socket tool on the ground, in grass, or in a location where socket face surfaces may be
damaged.
Pipe Ends And Fittings Must Be Properly Prepared For Fusion
A. Pipe must be cut X= with a tubing Cutter designed for plastic pipe.
H, Thoroughly wipe and remove all foreign material at the joining surfaces with a clean, jgh:lY_darlip
Gotten rag.
C. Inspect each and every fitting for out -of -roundness or damage, and wipe clean. Check inside pipe for
contaminants or obstructions.
D. Pipe cut wan angle will produce inadequate joints.
E. Flattened, damaged or out -of -round pipe- be rued.
F. Cleaning rags must not kwcL only damp.
G. Do not use gasoline, solvents or primers to clean the pipe or ltigtings. lactpropyl alcohol may be used to
t+emove. steins or adhesives.
H. For best rasults pipe and fitt+ngs should be swred in a shaded area during summer, and kept in a warns area

Fusion Procedures
Use A Proper Depth Gauge And Cold Ring
A. After the pipe end and fitting socket have been cleaned and inspected, place the depth gauge on the pipe end.
The depth gauge is used as a guide for positioning of the cold ring. After placing the depth gauge on the pipe,
hold the gauge fuTWy in place and clamp the cold ring around the pipe, hush against the depth gauge.
B. Using the depth gauge/cold ring combination assures that the heated pipe and fitting will join at the proper
depth. pruhibiting the pipe imn either penetrating too far into the fitting, creating a flow restriction, or
falling to peasants the Ruing deeply enough for adequate joint strength- The cold ring also helps keep the
Pipe round while it is being hattm&
PIPE END AND F:ITING ARE NOW READY FOR MEA TING
Perform A Dry Run Fusion
A. Always perform a dry run fusion when working in cramped or small areas; bottom of trenches, between floor
joiVA or rafters, trawl spaces, and =ks.
B. Do a oriel fusion at the start of each day. Especially in cold weather below 55T.
Pipes And Fittings Are Simultaneously Hearted
A- Work with the pipe memory to remove tension in the pipe before staking any fissions.
B. Grip the pipe behind the cold ring.
C. Push the pipe end (with cold ring attached) onto its socket face while simultaneously pushing the fitting over
lire apposite socket fast.
D. Pipe and fitting are pushed squarely together. and at the same rate of pressure, onto their respective socket
faces until the cold ring h&ML t.taurbe its socket face,
E. Fitting socket should be just flush with Ifte socket fact. Qan't fnree the fitting against the base of the
heated socket face.
F. lire fitting should only &{jQL touch the base of the heated socket face.
G. Too much pressure will cause a follbKjt of the fitting edge, shortening the actual socket depth and cresting a
gap whet The pipe and fiuing are pitied.
H. Begin the timing cycle as soon as the cold ring and fitting e4ge Contact the socket faces or the pipe and fitting
