on the location from the Owner.
2. Rods shall be driven into unexcavated portion of earth where possible.
3. Where rods must be driven into excavated areas, they shall be installed after
compaction of backfill is completed.
4. The top of the rod shall be approximately 18 inches below finished grade.
C. Connections
1. Buried connections:
a. All buried connections shall be the exothermic weld type.
b. Apply one coat, 15 mils dry film thickness, of coal tar or

2. Cable to equipment connections shall be made using compression type lug
connectors. Bolt lugs to equipment using terminals or holes specifically for
grounding. Do not use mounting or hold down bolts.
3. All conductive piping and structures shall be bonded and grounded using a
#2 A WG (minimum) bare copper wire. Use compression type lugs or bolted
connectors for bonding connections.

PART 3 EXECUTION
3.1 INSTALLATION
3.2
A. Install field mountea devices as follows
I. Mount on floor stands or wall as required.
2. Mount plumb and level.
3. Mount with bottom of box or instrument four feet above floor unless indicated
otherwise and instrument case spaced at least 1/2-inch away from wall.
4. Install supports as specified in SECTION 16050.
5. Install floor-mounted instruments on pipe stands.
B. Wiring

2. Connect all 120 volt ac power circuits. These circuits shall not be routed in
the same conduit as de signal cables.
FIELD TESTING
A. Instrument Tests and Adjustment
I. With each system variable transmitter disconnected from its normal source of
input signal, apply an input with manometer, instrument potentiometer, or other
device and adjust span and zero on all instruments transmitting, receiving, or
retransmitting the resulting variable current, and on all final control devices.
Check instruments and final control devices at several points over the instrument
measuring or control device span.
2. Apply manually adjustable current signals directly to receivers where required to
adjust zero and span and to check operation of the instrument over the-
measunng span.
3. Accurately measure variable current signals as required to adjust all receivers,
