3.3 REFRIGERATING CYCLE
3.3.1 CONDENSER, EVAPORATOR AND
CAPILLARY TUBE
1. Remove the insulation on the Heater/Evaporator
(H/E) assembly
2. Pierce the pinch-off tube to discharge the
refrigerant, using a refrigerant recovery system.
3. After discharging the refrigerant completely,
remove 2 screws between the housing assembly
and the H/E. (See Figure 26)
4. Lift the H/E and open the H/E around 45 degree
counterclockwise carefully.
5. Unbraze each of interconnecting tubes of the
evaporator and condenser carefully.
6. Remove the H/E assembly from the orifice.
(See Figure 27)
7. Unbraze the capillary tube at the connections of the
condenser and evaporator. (See Figure 28)
8. Remove 4 screws between the condenser and
evaporator. (See Figure 28)
3.3.2 COMPRESSOR
1. Discharge the refrigerant by using a refrigerant
Recovery System.
2. After purging the unit completely, unbraze the
suction and discharge tubes at the compressor
connections.
3. Remove the nuts and washers which fasten the
compressor. (See Figure 29)
