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) Figure 26 Figure 27 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) 4. Remove the compressor. (See Figure 29) Using Rotary Compressor models Figure 29 -17-

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)
4. Remove the compressor. (See Figure 29)
