7.4.11 Compressor Oil

NOTICE

Risk of improper compressor lubrication. Can cause compressor and refrigerant system damage.

Failure to use oil types, viscosities and quantities recommended by the compressor manufacturer may reduce compressor life and void the compressor warranty. See oil types specified in Table 10.

•Do NOT mix polyol ester (POE) and mineral-based oils.

•Do NOT mix oils of different viscosities.

Consult Emerson or the compressor manufacturer if you have questions.

7.5Compressor Replacement

Replacement compressors are available through your local Emerson office. Compressors are shipped in reusable packaging. If unit is under warranty, complete and include Liebert Service Credit Appli- cation (LSCA) with the compressor that is being returned. The original compressor should be returned in the same packaging.

Before Replacing or Returning a Compressor

Be certain that the compressor is actually defective. At a minimum, recheck a compressor returned from the field in the shop or depot for Hipot, winding resistance and ability to start before returning it. More than one-third of compressors returned for warranty analysis are determined to have nothing wrong. They were misdiagnosed in the field as being defective. Replacing working compressors unnec- essarily costs everyone.

7.5.1Compressor Functional Check

The following diagnostic procedure should be used to evaluate whether the compressor is working properly.

1.Proper voltage to the unit should be verified.

2.The normal checks of motor winding continuity and short to ground should be made to determine if the inherent overload motor protector has opened or if an internal motor short or ground fault has developed. If the protector has opened, the compressor must be allowed to cool sufficiently to allow it to reset.

3.Proper indoor and outdoor blower/fan operation should be verified. Condenser glycol flow should be verified.

4.With service gauges connected to suction and discharge pressure fittings, turn On the compressor. If suction pressure falls below normal levels, either the system charge is low on or there is a flow blockage in the system.

5.If suction pressure does not drop and discharge pressure does not rise to normal levels, reverse any two of the compressor power leads and reapply power to make sure compressor was not wired to run in reverse direction. If pressures still do not move to normal values, system is properly charged and solenoid valves function, the compressor is faulty. Reconnect the compressor leads as originally configured and use normal diagnostic procedures to check operation of the reversing valve.

6.To test if the compressor is pumping properly, the compressor current draw must be compared to published compressor performance curves using the operating pressures and voltage of the system. If the measured average current deviates more than ±15% from published values, a faulty compressor may be indicated. A current imbalance exceeding 15% of the average on the three phases should be investigated further.
