WARNING: Disconnect electrical power to the chiller to prevent personal injury before
attempting any internal maintenance. Only qualified personnel should service the internal
components or electrical wiring.

Condenser

On air-cooled chillers, the CONDENSER FINS should be cleaned by blowing compressed air through the
condenser from the fan side. Dirt and debris accumulate on the condenser fins over time and this build up can
severely reduce the performance of the chiller. Cleaning of the CONDENSER COIL FINS should be done
approximately every three months, depending upon cleanliness of your application.

Pump Motor

The PUMP MOTOR should be lubricated with thirty drops of SAE 20 oil once a year.

Circulation System

The CIRCULATION SYSTEM should be drained and flushed periodically to avoid build up and a possible flow
restriction caused by contaminants.
