SEALED REFRIGERATION SYSTEM REPAIRS

EQUIPMENT REQUIRED:

1.Voltmeter

2.Ammeter

3.Ohmmeter

4.Vacuum Pump (capable of 200 microns or less vacuum.)

5.Acetylene Welder

6.Electronic Halogen Leak Detector (G.E. Type H-6 or equivalent.)

7.Accurate refrigerant charge measuring device such as:

a.Balance Scales - 1/2 oz. accuracy

b.Charging Board - 1/2 oz. accuracy

8.High Pressure Gauge - (0 - 400 lbs.)

9.Low Pressure Gauge - (30 - 150 lbs.)

10. Vacuum Gauge - (0 - 1000 microns)

EQUIPMENT MUST BE CAPABLE OF:

1.Evacuation from both the high side and low side of the system simultaneously.

2.Introducing refrigerant charge into high side of the system.

3.Accurately weighing the refrigerant charge actually introduced into the system.

4.Facilities for flowing nitrogen through refrigeration tubing during all brazing processes.

HERMETIC COMPONENT REPLACEMENT

The following procedure applies when replacing com- ponents in the sealed refrigeration circuit or repairing refrigerant leaks. (Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.)

1.Recover the refrigerant from the system at the pro- cess tube located on the high side of the system by installing a line tap on the process tube. Apply gauge from process tube to EPA approved gauges from process tube to EPA approved recovery system. Recover CFCs in system to at least 5%.

2.Cut the process tube below pinch off on the suction side of the compressor.

3.Connect the line from the nitrogen tank to the suction process tube.

4.Drift dry nitrogen through the system and unsolder the more distant connection first. (Filter drier, high side process tube, etc.)

5.Replace inoperative component, and always install a new filter drier. Drift dry nitrogen through the system when making these connections.

6.Pressurize system to 30 PSIG with proper refrigerant and boost refrigerant pressure to 150 PSIG with dry nitrogen.

7.Leak test complete system with electric halogen leak detector, correcting any leaks found.

8.Reduce the system to zero gauge pressure.

9.Connect vacuum pump to high side and low side of system with deep vacuum hoses, or copper tubing. (Do not use regular hoses.)
