Im curious as to the proper steps i have to take in order to clean out a chiller condenser coil. Apparently the old compressor was "slugging" oil and iv been told it pushed the compressor oils into the condenser coil. no i have to clean out the coil. im also going to be replacing service valves, expansion valve and drier filters prior to connecting the rebuilt 75 ton trane chiller compressor.
It is a Trane, 75 ton, Air cooled chiller.
Prior to the replacement of compressor, it went off on safety 3 times for high head pressure.
the low oil pressure switch did not trip out.
and i didnt witness and oil movement in the compressor sight glass.
When the compressor eventually stopped running, its last reading were -
117 amp draw. 90PSI suction, 350Head, if im correct.
the compressor was extreamly hot was well, so i believe it wasnt coming back on the suction side although i had a 90 pressure reading.
Any takers on steps to clean coil and then possible issues?
