Component Access / Removal
Compressor Removal
The compressor sits on four grommets that are posi-
tioned over four tabs protruding up from the unit tray;
cotter pins are then inserted through holes at the top of
the tabs, above the compressor base and grommets.
To remove the compressor, first remove the kickplate,
door, lower hinge assembly, trim plate, slide cover
bracket, water filter panel, back panel and lower back
utility panel, then after capturing the refrigerant from the
sealed system (See Figure 5-34):
1. Remove electrical's cover and capacitor mounting
assembly by inserting a flat-bladed screwdriver
under capacitor and prying under tab while pulling
cover toward rear of unit and down, then push
cover down to release it from tabs on compressor.
2. Pull cover and capacitor away from compressor,
then disconnect wire leads from compressor electri-
cal's.
3. Using a tube cutter, cut suction and discharge tubes
approximately 1" from compressor stubs.
NOTE: Do not sweat tubing apart. Doing so will
induce moisture into the sealed system.
4. Extract cotter pins from above compressor grom-
mets, then lift compressor up off of unit tray and pull
toward rear of unit.
NOTE: Always replace the filter-drier when opening the
sealed system for service.
Evaporator/Heat Exchanger Assembly Removal
The evaporator is located at the top of the machine
under the top cover, atop the evaporator/spray bar
enclosure, with the heat exchanger running down the
back of the unit.
To remove the evaporator/heat exchanger assembly,
first remove the kickplate, top cover, fill tube clamp, fill
tube, back panel and lower back utility panel, then after
capturing the refrigerant from the sealed system (See
Figure 5-35):
1. Using a tube cutter, cut suction tube approximately
1" from compressor stub; cut hot gas tube approxi-
mately 1" from hot gas valve body; cut drier inlet
tube approximately 1" from drier.
NOTE: Do not sweat tubing apart. Doing so will
induce moisture into the sealed system.
2. Lift evaporator assembly from top of evaporator/
spray bar enclosure.
NOTE: Always replace the filter-drier when opening the
sealed system for service.
