4. Tighten the cable bushing nuts on the cord grip to ensure a watertight seal at the cable’s entry.
5. Remove the protective closures from the 3-way valve ports.
Neptune meters:
Connect a hose from line pressure to port 3 (normally open port) of the 3-way valve (see Figure 23). On some
systems, line pressure is available at an opening in the vapor eliminator housing. Connect another hose from
the 3-way valve’s port 1 (normally closed port) to the air eliminator. Connect a third hose from the 3-way
valve’s port 2 (common port) to the differential valve.
L.C./TCS Meters:
Connect a hose from the air eliminator to port 3 (normally open port) of the 3-way valve (see Figure 24). Con-
nect another hose from the 3-way valve’s port 1 (normally closed port) to the strainer cover. Connect a third
hose from the 3-way valve’s port 2 (common port) to the differential valve.

Instructions:
NOTE: When temperature is below 50˚F (10˚C), keep
resin in a warm place prior to mixing (e.g., in an
inside pocket next to body).
1. Attach red wires from 3-way valve to black and
white (+) wire from IB unit with wire nuts as shown
in 1. Connect diode wire with white band to
red/white (+) pair. Connect all black diode wire to
red/black pair.
2. Open epoxy package, and remove resin pak.
3. Holding resin pak as shown in 2, bend pak along
long length.
4. As shown in 3, firmly squeeze the RED SIDE of the
resin, forcing it through the center seal and into
BLACK SIDE.
5. Mix thoroughly to a uniform color by squeezing
contents back and forth 25-30 times.
6. Squeeze mixed, warm resin into one end of bag
and cutoff other end.
7. Slowly insert wiring connections into sealing pack
until they fit snugly against the opposite end.
8. Twist open end of bag and use tie wrap to close it
off, or wrap open end of bag with vinyl electrical
tape (not included) and position the taped end up
until the resin jells.
9. Place epoxy pack into junction box and screw on
cover as shown in 4.
