EMR3 Truck Installation 3-Way Safety Valve for Truck LP Gas Systems
32
INSTALLING THE 3-WAY VALVE
On the male pipe threads, use a pipe sealant when installing fittings or conduit to either
the valve or the junction box.
1. On the valve, install a rigid metal conduit nipple in the threaded opening, provided for the solenoid wiring. Run
the two red wires from the 3-way valve, through the nipple and into a metal junction box. Mechanically attach
the valve/nipple combination to junction box as shown in Figure 23 on page 32.
Even though the 3-way valve
will operate in any position, it will last longer and perform best if mounted vertically upright (port 3 up) .
Secure the junction box to the vehicle's frame.
2. Run a 2-wire shielded cable from the IB Box, located in the truck cab, to the 3-way valve junction box. Pass
the cable through a cord grip fitting in one of the J-box openings. Cut off 1-inch (25.4 mm) of the cable’s
shield and jacket, then strip off 1/2-inch (12.7 mm) of each wire’s insulation.
3. Using the wire nuts, connect the stripped wires from the IB box to the 3-way valve wires (step 1 in Figure 23).
There is no polarity to the 3-way valve’s wiring. Seal the wire nuts with epoxy sealant using one bag for both
wire nut connections and place bag in junction box (Steps 2 & 3 in Figure 23).
CAUTION: Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause allergic skin
reaction. Contains: epoxy resin and cycloaliphatic epoxycarboxylate. Precautions: Wear suitable
protective clothing, gloves, eye, and face protection. Use only in well ventilated areas. Wash thor-
oughly before eating, drinking, or smoking.

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.
