Tips for a Successful Installation (continued)

•

Always lubricate hose fittings with refrigerant oil when assembling to
refrigeration hoses.

•

Always install and lubricate o-rings with refrigerant oil when
connecting refrigeration hose fittings to component connections.

•

All refrigeration connections should be tightened securely using two
wrenches.

•

Refrigeration hoses should be installed onto components in such a way
as to allow for vibration and movement.THEY SHOULD NEVER BE
STRETCHED TIGHT!

•

Refrigeration hoses should be carefully routed from the vehicle’s
engine compartment, up the interior wall of the cargo area.

ELECTRICAL

•

Anti-corrosion gel (203-377) or equivalent should be applied to all
electrical connections.

•

All electrical harnesses should be neatly routed and secured with band
wraps or clamps.

•

Evaporator heater resistance wires must be installed as far as possible
into the drain hoses. NEVER CUT HEATER RESISTANCE WIRES!

•

Electrical power to the In-Cab controller (BAT, ACC) must be spliced
into the supplied 10 amp fuse and connected to the ON position of the
vehicle’s ignition switch.

•

The unit’s power wire (2) must be spliced into the supplied 60 amp fuse
and connected securely to the vehicle’s positive (+) battery connection.

•

If the vehicle is equipped with a battery disconnect switch, always
attach the 2 wire after the switch. This allows power to the unit to be
turned off by the battery disconnect switch.

•

The unit’s ground harness must be connected securely to the vehicle’s
negative (-) battery connection.

•

A separate ground wire must be installed from the engine driven
compressor to chassis ground. The location used on the vehicle chassis
should be clean and free of paint to make a proper ground path.
“Battery Installation and Cable Routing” on page 7 for details.

•

The In-Cab controller must only be mounted inside the vehicle.
It should be accessible and visible from the drivers position while not
interfering with the driver’s mobility, visibility or access to the vehicle
controls and instruments.

ELECTRIC STANDBY MODELS

NOTE: Thermo King recommends a 20 amp fused power source for
electric standby operation.

•

Verify the receptacle box is wired for the correct voltage for your
application.

•

The standby receptacle box should be installed securely to the exterior
of the vehicle. It should be easily accessible while not interfering with
the driver’s visibility or operation of the vehicle.

SYSTEM EVACAUTION AND CHARGING

•

The Liquid Injection Solenoid Valve, Liquid Line Solenoid Valves and
the Defrost Solenoid Valve must both be in the OPEN position during
evacuation procedures. The valves are normally in the closed position
and must be held open manually using special magnets (204-1074)
designed for this purpose. DO NOT put a magnet onto the Condenser
Blocking Solenoid Valve as this is a normally open valve and a magnet
will close it.

•

Thermo King Evacuation Station P/N 204-725 and Evacuation Station
Operation and Field Application Instructions (TK-40612) is required.

•

Never evacuate a system without a micron gauge.

•

The oil in the evacuation station vacuum pump should be changed after
each use.

•

Verify the refrigeration system is charged with the correct type and
amount of refrigerant for your application.

•

Verify the refrigeration system has been checked for leaks by using an
electronic leak detector.

•

Verify the SPR and CPR adjustment procedures were followed and the
unit operates at its maximum capacity.
