Cleaning the Condenser
CAUTION: Proper Water Treatment!
The use of untreated or improperly treated water may result in scaling, erosion, corrosion, algae or slime. It is
recommended that the services of a qualifi ed water treatment specialist be engaged to determine what water
treatment, if any, is required. The manufacturer assumes no responsibility for equipment failures which result from
untreated or improperly treated water, saline or brackish water.
Compressor Oil
CAUTION: Equipment Damage!
To prevent oil sump heater burnout, open the unit main power disconnect switch before removing oil from
the compressor.
Trane Polyolester Oil is the approved oil for the unit. Polyolester oil is extremely hygroscopic meaning it readily
attracts moisture. The oil can not be stored in plastic containers due to the hygroscopic properties. As with mineral
oil, if water is in the system it will react with the oil to form acids. Use Table 6 to determine the acceptability of the
oil. Trane approved oil is OIL0066E/OIL0067E. The proper charge amounts are given on General data. Note: Use an oil
transfer pump to change the oil regardless of chiller pressure.
For R1234ze, approved oil is OIL0066E/OIL0067E.

Running the chiller at minimum load is the best for the quickest return of oil to the separator and sump. The machine
still needs to sit for approximately 30 minutes before the level is taken. At minimum load, the discharge superheat
should be highest. The more heat in the oil as it lays in the sump, the more refrigerant will boil off in the sump and
leave more concentrated oil. The oil level in the oil sump can be measured to give an indication of the system oil
charge. Follow the procedures below to measure the level.
1. Run the unit fully unloaded for approximately 20 minutes.
2. Cycle the compressor off line.
