Vapor Intrusion Mitigation Plan
Dunavant Street
2250 Hawkins Street
Charlotte, North Carolina
Brownfields Project No. 19038-15-060
H&H Job No. RMR.002

1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for
installation of a vapor intrusion mitigation system (VIMS) at the Dunavant Street Brownfields
property (Brownfields Project No. 19038-15-060) located at 2250 Hawkins Street in Charlotte,
Mecklenburg County, North Carolina (Site or subject Site). A Site location map is included as
Figure 1. Current redevelopment plans for the Site include construction of a mixed-use multi-
family apartment buildings with associated amenities and leased commercial tenant spaces. The
proposed buildings include a slab-on-grade foundation with commercial tenant spaces,
residential spaces, and common areas on the ground-level.

The results of previous Site assessment activities indicate that volatile organic compounds
(VOCs) have been detected in Site groundwater at concentrations exceeding the North Carolina
Department of Environmental Quality (DEQ) risk-based vapor intrusion screening criteria and
that warrant vapor mitigation for ground-level components of the proposed Site building.
Therefore, this VIMP has been prepared for installation of a VIMS in accordance with Land Use
Restriction 6.b. of the recorded Notice of Brownfields Property for the Site to address potential
vapor intrusion concerns for the proposed buildings.

The VIMP is described in the following sections and was designed in accordance with the DEQ
Division of Waste Management (DWM) Vapor Intrusion Guidance (VI Guidance) and the DEQ
Brownfields Program Preliminary Vapor Intrusion Mitigation System Design Submittal New
Construction Minimum Requirements Checklist.

VMP Rev 2 text.doc
2.0 Design Basis

The VIMP is included in Sheets VM-1 and VM-2 as Attachment A and will be used to guide
construction of the VIMS. The VIMP includes installation of a 15-mil vapor barrier liner
manufactured by Stego Industries LLC (Stego) beneath bottom level portions of the building. A
technical specification obtained from Stego Industries for the vapor barrier is included in
Attachment B. The VIMP specifies that the vapor barrier will be installed per manufacturer
installation instructions (Appendix B).

In accordance with the manufacturer installation instructions, the Stego wrap will be installed
over the sub-slab aggregate and will completely cover the concrete slab placement area. Stego
wrap seams will be overlapped a minimum of six inches and all seams and penetrations will be
sealed using Stego tape and/or Stego mastic. The concrete slab will be placed directly on top of
the sealed Stego barrier to further seal the seams and penetrations. The concrete slab will also
seal the Stego wrap at the slab perimeter footers and complete the vapor barrier system for each
slab section.

Please note that thickened slabs will be installed beneath separation walls for the residential
units. In addition, a slab-on-grade fold and a retaining wall will be constructed beneath sections
separating the ground floor clubhouse/leasing office spaces and adjacent residential units (Sheets
VM-1 and VM-2). The commercial spaces and clubhouse/leasing office spaces will be
constructed with typical flat foundation slabs supported by columns. As shown on Sheet VM-2,
Stego wrap will be placed along the vertical concrete walls and sealed per manufacturer
instructions to create a continuous vapor barrier in these areas.

An equivalent vapor barrier liner approved by the engineer which meets the criteria specified in
Sheet VM-2 may also be used by the installation contractor. If an alternate equivalent vapor
barrier is selected, the DEQ Brownfields Program will be notified of the alternate liner for their
review and approval prior to installation.

S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
The VIMS is designed to prevent vapor intrusion into the buildings from potential subsurface
sources using a passive system. The VIMP includes sub-slab vapor extraction beneath the
ground-level residential and commercial spaces in order to reduce the potential for structural
vapor intrusion into occupied spaces of the proposed Site buildings. Sub-slab vapor extraction
will be accomplished using turbine ventilator fans and poly-vinyl chloride (PVC) vapor
collection/conveyance piping which will collect vapor from beneath the floor slabs of each
building and discharge the vapor through exhaust stacks above the building roof. Specifications
for the proposed turbine ventilator fans and PVC vapor collection/conveyance piping are
provided in Attachment B.

The VIMP includes Empire Model TV04G (galvanized) turbine ventilator fans (or approved
alternate) installed on the discharge end of the exhaust stacks on the roof. These fans are wind-
driven and have a rated exhaust capacity of 126 cubic feet per minute in a four mile per hour
wind. In order to enhance sub-slab vapor transmission and collection effectiveness, sub-slab
vapor collection piping will be installed within a minimum 4-inch thick course gravel layer
consisting of high permeability stone (clean #57 stone, or similar) which will be installed below
the ground-level concrete slab.

3.0 Quality Assurance / Quality Control

For quality assurance and quality control purposes, inspections will be conducted during various
phases of VIMS installation activities for each section of slab. Inspections will be performed
upon completion of horizontal collection system and gravel base placement, vapor barrier
installation prior to pouring the slab, vertical exhaust riser placement and connection, and fan
installations. Each inspection will be performed by, or under direction of the VIMS design
engineer certifying the VIMP. The inspections will include field logs and photographic log for
each section of slab. DEQ will be provided a minimum of a 48-business hour advanced notice
prior to inspections.

VMP Rev 2 text.doc
4.0 Post-Construction and Pre-Occupancy System Effectiveness Testing

Upon completion of VIMS installation activities, pilot testing will be conducted after the
concrete building slabs are poured and before the buildings are occupied to confirm that the
VIMS horizontal collection pipe network will provide adequate vacuum influence and
communication across the slab. For each slab section within the VIMS, one or more variable
speed vapor extraction fan will be connected to select vertical exhaust risers. Vacuum and air
flow measurements will be collected at varying speeds at each fan location, and vacuum
measurements will be collected at each vacuum measuring point (VM-1) for the VIMS treatment
area being evaluated. The results of the pilot tests will be submitted to DEQ Brownfields for
review upon completion of the testing and internal evaluation of the data collected.

As indicated in Sheet VM-1 of the VIMP, select vacuum measuring points have been designated
as temporary installations (blue triangles denoted by “TMP” nomenclature) for pilot testing
purposes. The designated temporary vacuum measuring point locations are proposed within
residential units or leased commercial tenant spaces and will likely not be accessible when the
building is occupied. Therefore, it is anticipated that the TMPs will be abandoned upon
completion of the influence testing. In addition to the TMPs, select vacuum measuring points
have been designated as permanent installations (blue bull’s eyes denoted by “MP”
nomenclature). Permanent vacuum measuring point locations have been selected for installation
in easily accessible public spaces in and around the proposed building for future monitoring as
needed.

As shown on VM-1, the VIMS has been designed to prevent potential vapor intrusion into the
proposed Site building using six (6) separate treatment systems. Upon completion of successful
pilot testing and prior to occupancy of the building, sub-slab vapor samples will be collected
from select permanent vacuum measuring points to evaluate the potential for structural vapor
intrusion within each VIMS treatment area. Proposed sub-slab vapor sampling activities are
described in the following section.

VMP Rev 2 text.doc
4.1 Sub-Slab Vapor Sampling

H&H proposes to collect nine (9) sub-slab vapor samples for laboratory analysis to evaluate the
potential for structural vapor intrusion into the proposed Site building. Proposed sub-slab vapor
sample locations are shown on Attachment C and will be collected from select permanent
vacuum monitoring points in each VIMS treatment area as follows:

 VIMS Treatment Area 1-northern portion of the residential building (MP-1 and MP-4);
 VIMS Treatment Area 2-southern portion of the residential building (MP-6 and MP-7);
 VIMS Treatment Area 3-western portion of the commercial space (MP-9 and MP-12);
 VIMS Treatment Area 4-eastern portion of the commercial space (MP-14);
 VIMS Treatment Area 5-northern portion of the clubhouse (MP-15); and
 VIMS Treatment Area 6-southern portion of the clubhouse (MP-18).

Each vacuum measuring point will be sealed using an expandable well cap equipped with a
Swagelok® sampling port. Dedicated Teflon sample tubing will be connected to the Swagelok®
sampling port using a brass nut and ferrule assembly to form an air tight seal. To evaluate the
reproducibility of the sample results, one duplicate sub-slab vapor sample will be collected using
a laboratory-supplied T-sampler.

Prior to sub-slab vapor sample collection, a helium leak check will be performed at each sample
location by constructing a shroud around the vacuum measuring point and flooding the air within
the shroud with helium gas. Helium concentrations inside the shroud will be measured using a
helium gas detector and near saturated conditions will be maintained within the shroud
throughout the leak check activities. Using a syringe and three-way valve, a sample will be
collected from the sample tubing outside the shroud and analyzed using the helium gas detector
to ensure that helium concentrations are less than 10% of the helium concentrations in the
shroud.

S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
Following a successful leak check, a laboratory-supplied stainless steel Summa sample canister
connected to in-line flow controllers with a vacuum gauge will be used to collect the sub-slab
vapor sample. The flow controller will be connected to the sample tubing at each sampling point
using a brass nut and ferrule assembly to form an air-tight seal. The flow controller will be pre-
set by the laboratory to regulate the vapor intake rate to approximately 100 milliliters per minute.
Once the sample train is assembled, the intake valve on the canister will be fully opened to begin
collection of the sub-slab vapor sample. Vacuum readings on the Summa canister will be
recorded prior to and following the sampling period to ensure adequate sample volume was
collected. A vacuum will be maintained within the canisters at the conclusion of the sampling
event.

After sample collection, the Summa canister’s valve will be closed, and the regulator will be
disconnected from the canister. The canisters will be placed in laboratory supplied shipping
containers, properly labeled and shipped under standard chain-of-custody protocols to a qualified
laboratory for analysis of VOCs by EPA Method TO-15. The laboratory will be requested to use
reporting limits that are below DEQ DWM Residential Vapor Intrusion Sub-slab and Exterior
Soil Gas Screening Levels (SGSLs).

Sub-slab vapor samples will be collected annually from the nine proposed permanent vacuum
measuring point locations for three consecutive years with the pre-occupancy sampling described
above accounting for the first annual event. The analytical data will be provided to DEQ within
48 hours of receipt and validation of the data for each annual sampling event. Based upon the
results of the sampling, H&H will make recommendations in accordance with the DWM VI
Guidance. It is anticipated that the recommendations will consist of one of the following:

 Detected compound concentrations for a VIMS treatment area do not indicate a potential
vapor intrusion concern and collection of indoor air samples is not warranted (per the
DWM VI Guidance, in the case where calculated cumulative risks are below 1x10-4 for
potential carcinogenic risks and below a hazard index of 1 for potential non-carcinogenic
risks).
7
S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
Detected compound concentrations for a VIMS treatment area indicate that there is
potential for vapor intrusion into the building and indoor air testing is warranted (per the
DWM VI Guidance, in the case where calculated cumulative risks are greater than 1x10-4
for potential carcinogenic risks or above a hazard index of 1 for potential non-
carcinogenic risks).
In the event evaluation of sub-slab vapor sample data indicates indoor air testing within a VIMS
treatment area is warranted, indoor air samples will be collected from representative ground floor
areas of that VIMS treatment area prior to occupancy to evaluate the potential for a completed
vapor intrusion pathway. In addition, one duplicate indoor air sample will be collected from a
sample location and an exterior background sample will be collected at the time of indoor air
sampling.
Indoor air samples will be collected in accordance with DEQ DWM VI Guidance. The locations
of the proposed indoor air samples (denoted by “IAS” nomenclature) are shown on
Attachment C and will be collected in the following areas:
VIMS Treatment Area 1 - northern portion of the residential building (IAS-1 thru IAS-3);
VIMS Treatment Area 2 - southern portion of the residential building (IAS-4 and IAS-5);
VIMS Treatment Area 3 - western portion of the commercial space (IAS-6 and IAS-7);
VIMS Treatment Area 4 - eastern portion of the commercial space (IAS-8);
VIMS Treatment Area 5 - southern portion of the clubhouse (IAS-9); and
VIMS Treatment Area 6 - northern portion of the clubhouse (IAS-10).
The background and indoor air samples will be collected using 6-liter stainless steel Summa
sample canisters connected to in-line flow controllers with a vacuum gauge. The
flow controllers will be set by the laboratory to allow the samples to be collected
over an approximately 8-hour period in areas of the building designated for commercial uses
and over an approximately 24-hour period in areas of the building designated for residential
uses. A 3-foot long sampling cane will be connected to the flow controller so that the
sample intake point is positioned approximately 5 ft above grade (typical breathing zone
height) when the
8
S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
sample canister is set on its base. Prior to and after the indoor and background air samples are
collected, vacuum in the canisters will be measured using a laboratory-supplied vacuum gauge
and recorded by sampling personnel. A vacuum will be maintained within the canisters at the
conclusion of the sampling event.
The starting and ending vacuum in each canister will be recorded on the sample chain-of-
custody. The sample canisters will then be labeled and shipped under standard chain-of-custody
procedures to a qualified laboratory for analysis of select VOCs by EPA Method TO-15. The
laboratory will be instructed to analyze for only those compounds detected above the laboratory
method detection limit in the previously collected sub-slab vapor samples from that VIMS
treatment area. The laboratory will be requested to use reporting limits that are below DEQ
DWM Residential Vapor Intrusion Indoor Air Screening Levels (IASLs).
A report of the indoor air sampling will be submitted to DEQ within 21 days of completion of
the sampling. The analytical data will be provided to DEQ within 48 hours of receipt and
validation of the data. Based upon the results of the sampling, H&H will make
recommendations in accordance with the DWM VI Guidance. It is anticipated that the
recommendations will consist of one of the following:
The VIMS is effective and no further sampling of indoor air is warranted (per the DWM
VI Guidance, in the case where calculated cumulative risks are below 1x10-6 for potential
carcinogenic risks and below a hazard index of 1 for potential non-carcinogenic risks).
Additional indoor air sampling is warranted to confirm that the VIMS is effective (per the
DWM VI Guidance, in the case where calculated cumulative risks are within the range of
1x10-4 and 1x10-6 for potential carcinogenic risks and below a hazard index of 1 for
potential non-carcinogenic risks).
Active fans will be installed as part of the VIMS and follow-up sampling will be
performed after installation of the fans (per the DWM VI Guidance, in the case where

9

S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
calculated cumulative risks are greater than 1x10-4 for potential carcinogenic risks or
above a hazard index of 1 for potential non-carcinogenic risks).

Should results of post-construction indoor air testing from any VIMS treatment area indicate that
active fans are warranted to prevent vapor intrusion into the Site building, active fans will be
installed at the exhaust end of all vent risers to convert each of the six VIMS treatment areas into
active sub-slab depressurization systems.

5.0 Post-Occupancy Testing

The VIMS is proposed as a passive system which will utilize sub-slab vapor extraction through
vapor extraction piping and wind-driven turbine ventilator fans. As such, post occupancy
differential pressure testing is not anticipated. If the VIMS is converted to an active system
based on results of post-construction and pre-occupancy indoor air assessment results, mitigation
system modifications and plans for additional indoor air sampling and long-term differential
pressure monitoring across the slab will be submitted to the DEQ Brownfields Program for
approval prior to implementation. Specifications for the fans to be used, if conversion to an
active system is deemed necessary, are included in Attachment B.

6.0 Future Tenants & Building Uses

The future use of the proposed Site building is multi-family residential with associated amenities
and leased commercial tenant spaces. The VIMS accessible piping will be labeled with “Vapor
Mitigation – Contact Maintenance Dept.”, or similar, at intervals of no greater than 10-linear
feet. If the mitigation piping is exposed, damaged, altered, or repaired, the building maintenance
department will notify H&H, or a North Carolina Professional Engineer (PE), to provide
oversight and inspections in a similar manner as those described above. The PE will notify the
DEQ Brownfields Program of the changes or repairs and provide a report documenting the
activities for DEQ Brownfields record.

10

S:\AAA-Master Projects\Ram Realty - RMR\RMR-002 Dunavant Street Brownfields\VMP\FINAL to DEQ\Rev 2\2250 Hawkings
VMP Rev 2 text.doc
7.0 Reporting

Following confirmation that the mitigation system is installed, effective, and operating properly,
a North Carolina PE-certified report documenting installation of the mitigation system will be
submitted to the DEQ Brownfields Program. The report will summarize VIMS installation
activities, quality assurance and quality control measures, post-construction and pre-occupancy
system effectiveness testing including sub-slab vapor and indoor air assessment results (if
warranted), and an opinion as to whether the VIMS was installed in accordance with the DEQ
Brownfields approved VIMP. The report will include photographs, inspection documents, as-
built construction figures, and safety data sheets for materials used during construction that could
be contribute to background indoor detections (if needed).

STEGO ® WRAP VAPOR BARRIER
ASTM E 1745 Class A-B-C Compliant
is made with our proven trade
secret blend of prime virgin resins
and additives. Stego Wrap Vapor
Barrier is an ASTM E 1745 Class A
Vapor Barrier (Below 0.01 perms).
We focus on producing a product
that will maintain its extremely low
permeance for the life of a building.
The protection of Stego Wrap Vapor
Barrier provides the flexibility to
change flooring types and overall
building use without worrying about
below-slab moisture vapor.

SUPERIOR DEFENSE Against Floor Failures:
Experts say “the need for a vapor barrier (as opposed to a vapor retarder) is becoming
increasingly clear.” Concrete Construction Magazine, August 2003, p.18.
Infiltration of moisture through concrete slabs is a major building defect liability.
Stego Wrap Vapor Barrier has an extremely low permeance preventing water vapor,
soil gases (i.e. Radon), alkaline salts and soil sulfates from compromising the integrity
of the building envelope and leading to serious problems with the concrete slab, floor
coverings and indoor air quality. Stego Wrap Vapor Barrier is the best protection
against these costly failures.
MOLD PREVENTION:
Mold needs three things to survive: moisture, sustained temperature (between 50° and
122° F), and a food source (dust, drywall, etc.). In any given building environment,
contractors can only control one of these variables: moisture. Mold spores are present
in 100% of building interiors. If moisture is allowed into your building environment,
mold can and will grow. Toxic molds like Stachybotyrus can be fatal for nearly 5% of
people (Institute of Medicine 1993), and cause a variety of serious health problems
in others. Several recent well-publicized cases involving toxic mold have resulted
in multimillion-dollar insurance settlements. Many of the nation's leading Insurance
companies have severely limited or removed coverage for mold claims fearing that
these claims will bankrupt their companies. Now more than ever, it is critically
important that extra attention be paid to preventing the intrusion of moisture vapor
from your below-slab environment. Stego Wrap Vapor Barrier offers the level of
protection that many architects are now seeking and is considered to be inexpensive
insurance against these costly failures.
LONGEVITY AND STRENGTH:
Stego Wrap Vapor Barrier is NOT made with recycled materials and will not degrade.
Prime, virgin resins are the key. Molecules within Stego Wrap "interlock" to provide
strength, durability and unprecedented resistance to moisture vapor and radon gas.
Stego Wrap’s puncture resistance is excellent. Stego Wrap will not tear, crack, flake,
snag or puncture, even when 18,000 lb. laser-screed machines are driving directly
across the barrier (see the reverse side for Stego Wrap Vapor Barrier’s specifications).
THE STEGO® ADVANTAGES
INSTALLATION INSTRUCTIONS: (Based on ASTM E 1643)
Unroll Stego Wrap over the area where the slab is to be placed. Stego
Wrap should completely cover the concrete placement area. Overlap
seams 6 inches and tape using Stego Tape. All penetrations and
blockouts should be sealed using a combination of Stego Wrap,
Stego Tape and/or Stego Mastic. If the Stego Wrap is damaged,
cut a piece from the Stego Wrap roll, place over the damaged area,
and tape around all edges. Concrete may be placed directly on Stego
Wrap. For additional information, please refer to Stego's complete
installation instructions.
STEGO ® TAPE:
STEGO WRAP RED POLYETHYLENE TAPE (3.75” x 180’/roll) is specially designed to seal seams and penetrations
on Stego Wrap installations. The acrylic, pressure-sensitive adhesive provides permanent bonding and quick-stick
properties. The area to be bonded should be free of dust, dirt and moisture.

STEGO CRETE CLAW® TAPE
Stego Crete Claw® Tape provides an innovative and economical way to secure
plastic film to concrete while the concrete is still wet.
Crete Claw is a multi-layered tape/detail strip that will mechanically lock Stego
Wrap Vapor Barrier to concrete. The patent-pending design allows wet concrete to
cast into the textured surface of Crete Claw. Just stick Crete Claw to Stego Wrap
prior to concrete placement, then place the concrete directly over the system.
Stego Crete Claw can be used in place of Stego Tape to seal joints in Stego Wrap
Vapor Barrier providing a dual purpose and helping to offset costs. ANGLED TOP VIEW

Other more expensive products rely
on chemical reaction or geotextile
to bond with concrete making it all
but impossible to properly install the
vapor barrier. Often in pursuit of the
all-in-one product, the performance
characteristics of the vapor barrier
are compromised. Because Crete
Claw Tape is applied as a separate
accessory to the vapor barrier, it
does not interfere with the ability to
detail around penetrations or repair

seams and around the perimeter, then it is more than strong enough
to support Stego Wrap. If determined by the architect or engineer,
additional Crete Claw may be specified.
5. Prior to the placement of concrete, ensure that Crete Claw is free
of dirt or debris to ensure maximum bond to the concrete.
These are general instructions. Installation requirements may change

UNDER-SLAB INSTRUCTIONS:
1. Stego Wrap can be installed over an aggregate, sand, or tamped earth
base. It is not necessary to have a cushion layer or sand base, as Stego
Wrap is tough enough to withstand rugged construction environments.
2. Unroll Stego Wrap over the area where the slab is to be placed. Stego
Wrap should completely cover the concrete placement area. All joints/
seams both lateral and butt should be overlapped a minimum of
six inches and taped using Stego Tape.
NOTE: The area of adhesion should be free from dust, dirt, moisture, and
frost to allow maximum adhesion of the pressure-sensitive tape.
3. ASTM E 1643 requires sealing the perimeter of the slab. Extend vapor
retarder over footings and seal to foundation wall, grade beam, or
slab at an elevation consistent with the top of the slab or terminate
at impediments such as waterstops or dowels. Consult the structural
engineer of record before proceeding.
SEAL TO SLAB AT PERIMETER:*
NOTE: Clean the surface of Stego Wrap to ensure that the area of adhesion is
free from dust, dirt, moisture, and frost to allow maximum adhesion of the
pressure-sensitive adhesive.
a. Install Crete Claw® on the entire perimeter edge of Stego Wrap.
b. Prior to the placement of concrete, ensure that the top of Crete Claw
is free of dirt, debris, or mud to maximize the bond to the concrete.

1.0 SYSTEM DESIGN CONSIDERATIONS 1.1 INTRODUCTION The RP Series Radon Fans are intended for use by trained, professional Radon mitigators. The purpose of this instruction is to provide additional guidance for the most effective use of an RP Series Fan. This instruction should be considered as a supplement to EPA standard practices, state and local building codes and state regulations. In the event of a conflict, those codes, practices and regulations take precedence over this instruction. 1.2 ENVIRONMENTALS The RP Series Fans are designed to perform year-round in all but the harshest climates without additional concern for temperature or weather. For installations in an area of severe cold weather, please contact RadonAway for assistance. When not in operation, the fan should be stored in an area where the temperature is never less than 32 degrees F. or more than 100 degrees F. 1.3 ACOUSTICS The RP Series Fan, when installed properly, operates with little or no noticeable noise to the building occupants. The velocity of the outgoing air should be considered in the overall system design. In some cases the "rushing" sound of the outlet air may be disturbing. In these instances, the use of a RadonAway Exhaust Muffler is recommended.
(To ensure quiet operation of ENERGY STAR qualified in-line and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the
installation. For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan). 1.4 GROUND WATER In the event that a temporary high water table results in water at or above slab level, water may be drawn into the riser pipes thus blocking air flow to the RP Series Fan. The lack of cooling air may result in the fan cycling on and off as the internal temperature rises above the thermal cutoff and falls upon shutoff. Should this condition arise, it is recommended that the fan be turned off until the water recedes allowing for return to normal operation. 1.5 SLAB COVERAGE The RP Series Fan can provide coverage up to 2000+ sq. ft. per slab penetration. This will primarily depend on the sub-slab material in any particular installation. In general, the tighter the material, the smaller the area covered per penetration. Appropriate selection of the RP Series Fan best suited for the sub-slab material can improve the slab coverage. The RP140/145/155 are best suited for general purpose use. The RP260 can be used where additional airflow is required and the RP265/380 is best suited for large slab, high airflow applications. Additional suction points can be added as required. It is recommended that a small pit (5 to 10 gallons in size) be created below the slab at each suction hole.
IN020 Rev K Page 4 of 8
1.6 CONDENSATION & DRAINAGE Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below its dew point. This can occur at points where the system piping goes through unheated space such as an attic, garage or outside. The system design must provide a means for water to drain back to a slab hole to remove the condensation. The RP Series Fan MUST be mounted vertically plumb and level, with the outlet pointing up for proper drainage through the fan. Avoid mounting the fan in any orientation that will allow water to accumulate inside the fan housing. The RP Series Fans are NOT suitable for underground burial. For RP Series Fan piping, the following table provides the minimum recommended pipe diameter and pitch under several system conditions.
Pipe
Dia.Minimum Rise per Ft of Run*
@25 CFM @50 CFM @100 CFM @200 CFM @300 CFM
6" - 3/16 1/4 3/8 3/4
4" 1/8 1/4 3/8 2 3/8 -
3" 1/4 3/8 1 1/2 - -
*Typical RP1xx/2xx Series Fan operational flow rate is 25 - 90 CFM 0n 3” and 4” pipe.
(For more precision, determine flow rate by measuring Static Pressure, in WC, and
correlate pressure to flow in the performance chart in the addendum.)
Under some circumstances in an outdoor installation a condensate bypass should be installed in the outlet ducting as shown. This may be particularly true in cold climate installations which require long lengths of outlet ducting or where the outlet ducting is likely to produce large amounts of condensation because of high soil moisture or outlet duct material. Schedule 20 piping and other thin-walled plastic ducting and Aluminum downspout will normally produce much more condensation than Schedule 40 piping. The bypass is constructed with a 45 degree Wye fitting at the bottom of the outlet stack. The bottom of the Wye is capped and fitted with a tube that connects to the inlet piping or other drain. The condensation produced in the outlet stack is collected in the Wye fitting and drained through the bypass tube. The bypass tubing may be insulated to prevent freezing. 1.7 "SYSTEM ON" INDICATOR A properly designed system should incorporate a "System On" Indicator for affirmation of system operation. A manometer, such as a U-Tube, or a vacuum alarm is recommended for this purpose.

IN020 Rev K Page 5 of 8
1.8 ELECTRICAL WIRING The RP Series Fans operate on standard 120V 60 Hz. AC. All wiring must be performed in accordance with the National Fire Protection Association’s (NFPA)”National Electrical Code, Standard #70”-current edition for all commercial and industrial work, and state and local building codes. All wiring must be performed by a qualified and licensed electrician. Outdoor installations require the use of a U.L. listed watertight conduit. Ensure that all exterior electrical boxes are outdoor rated and properly sealed to prevent water penetration into the box. A means, such as a weep hole, is recommended to drain the box. 1.9 SPEED CONTROLS The RP Series Fans are rated for use with electronic speed controls, however, they are generally not recommended. If used, the recommended speed control is Pass & Seymour Solid State Speed Control Cat. No. 94601-I. 2.0 INSTALLATION The RP Series Fan can be mounted indoors or outdoors. (It is suggested that EPA recommendations be followed in choosing the fan location.) The RP Series Fan may be mounted directly on the system piping or fastened to a supporting structure by means of optional mounting bracket.

IN020 Rev K Page 6 of 8
2.1 MOUNTING Mount the RP Series Fan vertically with outlet up. Insure the unit is plumb and level. When mounting directly on the system piping assure that the fan does not contact any building surface to avoid vibration noise. 2.2 MOUNTING BRACKET (optional) The RP Series Fan may be optionally secured with the RadonAway P/N 25007-2 (25033 for RP385) mounting bracket. Foam or rubber grommets may also be used between the bracket and mounting surface for vibration isolation. 2.3 SYSTEM PIPING Complete piping run, using flexible couplings as means of disconnect for servicing the unit and vibration isolation. 2.4 ELECTRICAL CONNECTION Connect wiring with wire nuts provided, observing proper connections (See Section 1.8):
Fan Wire Connection
Green Ground
Black AC Hot
White AC Common
2.5 VENT MUFFLER (optional) Install the muffler assembly in the selected location in the outlet ducting. Solvent weld all connections. The muffler is normally installed at the end of the vent pipe. 2.6 OPERATION CHECKS _____ Verify all connections are tight and leak-free. _____ Insure the RP Series Fan and all ducting is secure and vibration-free. _____ Verify system vacuum pressure with manometer. Insure vacuum pressure is less than maximum recommended operating pressure (Based on sea-level operation, at higher altitudes reduce by about 4% per 1000 Feet.) (Further reduce Maximum Operating Pressure by 10% for High Temperature environments)
See Product Specifications. If this is exceeded, increase the number of suction points. _____ Verify Radon levels by testing to EPA protocol.
