CHILLER MAINTENANCE
WARNING: Disconnect electrical power before performing any maintenance on the Chiller.
Condenser
On air cooled chillers, the CONDENSER FINS should be cleaned by blowing compressed air through the con-
denser from the fan side. Dirt and debris accumulate on the condenser fins over time, and this build up can se-
verely reduce the performance of the Chiller. Cleaning of the CONDENSER FINS should be done
approximately every three months, depending upon the cleanliness of your application.
Fan Motor
On air cooled chillers the condenser FAN MOTOR should be lubricated every 6 months with a few drops of SAE
10 oil.
