NOTE: System operating pressures must be near normal before valve can shift . REVERSING VALVE DESCRIPTION/OPERATION The Reversing Valve controls the direction of refrigerant fl ow to the indoor and outdoor coils. It consists of a pressure-operated, main valve and a pilot valve actuated by a solenoid...

Reversing Valve in Heating Mode When sluggish or stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. Should the valve fail to shift from coooling to heating, block the air fl ow through the out...

8. Pressurize sealed system with a combination of R-22 and nitrogen and check for leaks, using a suitable leakdetector. Recover refrigerant per EPA guidelines. 9. Once the sealed system is leak free, install solenoid coil on new valve and charge the sealed system by weighing in the proper amount and...

Exter nal Overload With power off, remove the leads from compressor termi-nals. If the compressor is hot, allow the overload to cool before starting check. Using an ohmmeter, test continu-ity across the terminals of the external overload. If you do not have continuity; this indicates that the overlo...

Recommended procedure for compressor replacement 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing. 2. Recover all refrigerant from the system though the process tubes. PROPER HANDLING OF RECOVERED REFRIGERANT A...
