Disassembly Procedures

!

WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to unit before following any disassembly procedures.

5. Disconnect wire from compressor terminals

6. Remove retaining clips from compressor mounts. Lift compressor from mounting rails and transfer the rubber grommets to replacement compressor.

7. Set replacement compressor into position and install retaining clips.

8. Remove all rubber plugs, clean the stubs of the compressor and compare the size of tubing to stubs of replacement compressor. It may be necessary to swage the copper tubing in order to make the joints.

9. Install a six inch (152 mm) long copper tube to low side process tube on the compressor. Add service valve to end of this tube.

10.Connect all tubing, apply flux to compressor stubs and solder all the joints. Excess flux must be wiped off after soldering.

11. Install a new drier.

12.Visually check all joints for leaks. Evacuate and recharge the system.

13.Reconnect wire leads to compressor terminals and test run the unit to verify proper operation.

14.Pinch process tube and cut off the service valve.

Solder the joint and test for leaks.

12.Pull entire shelving assembly out of cabinet and position to allow detachment of heat exchanger.

Replacing Heat Exchanger Refrigerated

Shelf Models

1. Disconnect line cord from electrical outlet.

2. Install a service valve as close as possible to the tip of process tube, for easy pinch-off after recharging the system.

3. Connect a hose to the service valve and capture the charge.

NOTE: Effective July 1, 1992, before opening any refrigeration system it is the responsibility of the service technician to capture the refrigerant for safe disposal.

4. Remove butyl sealer from around the tube entry hole.

5. Unsolder suction tubing at compressor stub or cut tubing three inches (76 mm) from compressor stub.

6. Cut drier from condenser tubing. Then cut drier from capillary tube.

7. Straighten heat exchanger tubing to slide tube through entry hole from inside the cabinet.

8. Remove clamp retaining the control feeler tube to underside of second shelf (counting downward).

9. Carefully bend feeler tube down against liner side to be out of the way.

10.Remove screws securing top freezer plate to liner top. As front edge of plate drops clearing the liner.

11. Carefully remove each shelf from food liner support rails. Push outward on liner side just above front retainer embossment. Lift shelf front free of retainer.

If necessary, repeat this operation on opposite side.

Freezer Shelf Assembly Joints

Refrigerated Shelf Model

13. Unsolder capillary tube and suction line (cut suction line away from original joint and swedge the end of it for new tubing, if desired).

14.Clean joints and solder new heat exchanger to shelving assembly. Clean & paint soldered joints before reinstalling evaporator.

15.Transfer vinyl insulating sleeve to new heat exchanger. Tape the same points.

16.Carefully position assembly back in the cabinet, verify heat exchanger tubing passes through the opening without damaging the vinyl sleeve.

17.Carefully work each shelf into its proper support rails.

Replace non-refrigerated shelf in the same manner.

18.Secure control feeler tube to correct shelf with the clamp. Verify feeler tube rests firmly against shelf surface to obtain thermal contact.

19.Fasten top freezer plate, verifying all spacers are in place.

20.Form heat exchange so it is similar in position to the original. Be careful when bending the tubing at the entry hole to prevent kinks.

21.Pack entry hole with butyl sealer.

22.If suction tubing was cut from compressor when removed, swedge compressor suction tube to fit replacement suction tubing.

23.Solder the suction lines.

24.Install new drier.

25.Visually check all joints for leaks. Evacuate and recharge the system.

26.Test run the unit to verify proper operation.

27.Pinch process tube and cut off the service valve.

Solder the joint and test for leaks.
