refrigerant hose assembly up through the boot into the tool compartment. Attach the #8 hose to the
condenser. See Figures 4 and 5.
b. Attach the (30”) #6 refrigerant hose assembly to the #6 refrigerant hose fitting on the condenser, then
route and attach it to the "in-port" on the receiver drier. See Figure 4.
Note: Use a tie wrap to secure the #6 hose assembly for the front frame support.
c. Attach (56'" #6 refrigerant hose assembly to the "out-port" of the receiver drier, then route it up
through the boot and into the tool compartment. See Figures 4 and 6.
d. Attach trinary wire harness to trinary switch on receiver/drier assembly. Route black wire from the
trinary to the compressor clutch. Route trinary and condenser wires up through boot into tool
compartment. Provide sufficient clearance around sharp edges to prevent damage to insulation.

of opening.
b. Drill (2) 3/16 diameter holes for duct support at the end closest to the driver.
2. Install unit in tool compartment opening and secure using (4) 1/4-20 nuts and screws for unit and (2) #14
sheet metal screws at driver's end of unit duct.
Note: if truck has been factory equipped with mounting holes, use metric screws provided in kit.
Note: If necessary, loosen mounting brackets where they attach to unit and adjust unit to provide
best fit and appearance. Re-tighten all screws
Note: Make sure drain tube remains attached to both sides of the unit and is routed through 7/8"
hole in tool compartment floor.
3. Connect #10 and #6 refrigerant hose fittings to expansion valve. Push the hoses as far forward as
possible and secure them with a tie wrap. See Figure 6.
Note: Support expansion valve with a wrench when tightening refrigerant hose fittings to avoid
damage to evaporator. Wrap refrigerant hoses and expansion valve with refrigeration tape to
prevent condensation inside the tool compartment area.

FINAL ASSEMBLY AND CHECK.
1. Reinstall fresh air-intake hose, glove box and center dash panel.
2. Connect the batteries.
3. Evacuate the system, test for leaks and charge with R-12 refrigerant. (R-134a for R-2110-19)
4. Turn the ignition switch to the "on" position, place the fan speed switch on high. a. The clutch should click
on and be engaged. If not, see step #8. b. The evaporator blower should be turning at high speed.
5. Turn the fan speed switch to medium and low positions and check that the evaporator blower slows
down.
6. Turn the fan speed switch to the "off" position and check that the compressor clutch disengages.
7. Start engine and run at 1500-2000 RPM. Turn fan speed switch to high. Check sight glass on receiver
drier for bubbles. Add 6 to 8 ounces more R-12 after the sight glass clears.
Note: Be aware that the sight glass may appear "milky" when charging with R-134a. Be careful not
to overcharge the system.
8. Make sure clutch cycles on and off as system is operating.
Note: If clutch does not engage, the system may not have been charged to a high enough pressure
to actuate the trinary switch. Place a jumper wire across the switch and run system until it is
fully charged then remove jumper wire.
9. Fill out service label properly and adhere in prominent location.
