Periodic Maintenance
Overview
Use of a periodic maintenance
program is important to ensure
the best possible unit
performance and efficiency.
Daily Maintenance Checks
Check the chiller’s evaporator
and condenser pressures, and
discharge oil pressure.
IMPORTANT:
IT IS HIGHLY
RECOMMENDED THAT THE
OPERATING LOG BE
COMPLETED ON A DAILY BASIS.
Check the oil level in the chiller oil
sump using the two sight glasses
provided in the oil sump head.
When the unit is operating, the oil
level should be visible in the lower
sight glass.
Weekly Checks
Check the following after the
machine has been in operation for
at least 30 minutes:
1. Chilled water and condenser
water entering and leaving
temperatures.
2. Current drawn by the
compressor (Amps).
3. Oil level in the oil sump. The oil
level must be visible in the sight
glass.
4. Condenser pressure, evaporator
pressure.
5. Unusual noise, vibration, and so
