MAINTENANCE
1. Th e system should be checked periodically to make sure that the refrigeration system(s) is operating properly. Use only the
services of cer tifi ed refrigeration mechanics for inspection and maintenance checks or service operations.
2. WATER COOLED CONDENSERS - Water cooled condensers should be checked for scale build-up and blockage. Th is
should be checked annually; if high head pressure problems occur a check of the condenser should be performed.
3. AIR COOLED CONDENSERS - Air cooled condenser coils must be kept clean through a regular preventive mainte-
nance program.
4. Compressor oil level should be checked regularly. Oil should be visible in the oil sight glass (located on the side of the
compressor) . Compressor oil sight glass should be 1/4 to 1/2 full.
5. Periodically check all electrical connections for possible loose or corroded wiring.
6. Monitor system pressures daily and amperages monthly.
7. Check system glycol tank level and percentage for proper freeze point. Th e freeze point should be at least 20 degrees F
lower than the operating setpoint temperature.
