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 PTC OR OVERLOAD PROTECTOR
(OLP) FOR RECIPROCATING
COMPRESSOR (DH304/DH300M/DH300E)
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 screw or nut which fastens the
terminal cover
4. Disconnect the lead wire from the overload
protector or PTC assembly.
5. Remove the overload protector(OLP) or PTC
assembly. (See Figure 29)
3.3.3 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 30)
4. Remove the compressor. (See Figure 30)
