If filter-drier or suction strainer is dirty or discolored, repeat steps 4-6 until system is cleaned.

Sign off on the daily compressor maintenance

Warning: This inspection requires trained personnel with PPE!

After 2 to 4 hours of operation, inspect compressor oil for discoloration and/or acidity.

Does the oil show signs of contamination?

If oil shows signs of contamination, replace oil and filter-driers and clean the suction strainer.

NOTE: When testing for moisture and acidity, be sure the test kit used is appropriate for the refrigerant (CFC, HCFC, or HFC) and the oil (mineral, alkylbenzene, or POE) in the system.

Select the type of refrigerant used

Carrier’s Total Test Kit is accurate for CFC and HCFC air-conditioning applications. If used with POE oils, Total Test Kit will indicate acid, but is not an accurate indicator of moisture.
