Refrigeration Compressor Kit Installation Manual

Failure to comply could result in serious injury, death or damage to the equipment.

To install a kit in either the 1050XR and 1550XR cooling units, proceed as follows:

1. Remove back access grille (on side where power switch

is located) to expose the compressor terminal cover.

2. Remove compressor terminal cover.

3. Perform electrical check on the compressor to confirm if it is inoperative.

4. If compressor is inoperative, drain water from evaporator tank.

5. Remove back panel for access to the compressor, See Figure 2.

6. Remove screws securing electrical box to rear panel.

NOTE: Do not vent refrigerant to atmosphere.

7. Install one line tapping valve on suction process line on the compressor, and a second line tapping valve on the

discharge process line located on the dual inlet strainer/drier.

8. Connect Refrigerant Recovery System to the refrigeration system.

9. Using Refrigerant Recovery System, remove refrigerant from the refrigeration system.

10. At each side panel, remove screws which support cabinet bulkhead to which evaporator is secured.

11. In front panel, loosen, but do not remove screws which support cabinet bulkhead to which evaporator tank is

secured.

12. To gain clearance between top of compressor and cabinet bulkhead, raise cabinet bulkhead up from 3/4 to 1

inch and prop with a piece of 1 x 2 inch wood cut to length.

13. At the compressor, remove hex head bolts, grommet spacers and grommets securing compressor to the base.

14. Slide the compressor toward the rear of the Unit, allowing compressor to slide off base mounting pads to gain

maximum clearance between top of compressor and cabinet bulkhead.

15. Refer to main text of this manual for procedure to replace a compressor.

16. Using new grommet spacers and grommet kit, secure the compressor in place.

17. Connect electrical wiring to compressor and attach protective cover.

18. Apply electrical power to unit.

19. Start and run system for about 5 minutes. Empty evaporator tank should frost entirely over contact area.

20. Remove electrical power from unit.

21. Pinch off and weld process line as described in main text.

22. Fasten cabinet bulkhead in position using removed and loosened screws.

23. Fill evaporator tank with water.

24. Install top cover.

25. Apply electrical power to unit.

26. Operate unit.
