Heat Controller BHD-301-C Refrigerating Cycle, CONDENSER, Evaporator and Capillary Tube

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.	Figure 26
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)
