WARNING: Electrical Hazard

Before performing any work on this item, disconnect and lock out electrical power sources to prevent injury from unexpected energization or startup. Be sure that power to the chiller is OFF when doing any maintenance on the chiller. Follow all safety rules when performing any maintenance on this equipment.

CAUTION: Hot Surfaces

Always protect yourself from hot surfaces when working on the chiller, especially when working on or around the compressor and condenser. These devices can reach over 160°F {71°C}. Allow these devices to cool before performing any maintenance or troubleshooting.

The air-cooled condenser and condenser filter can accumulate dirt and clog quickly if it is ran in a dusty or dirty environment. A clogged condenser or condenser filter increases refrigerant discharge pressure, lowers performance, and may cause the fan motors and compressor to overheat.

To clean the air-cooled condenser:

1Disconnect and/or lockout main power to the chiller.

2Remove the chiller’s top lid, by first removing both side panels and then the four

(4) retaining bolts that secure the chiller’s top lid.

3Remove the filter, that is located towards the back of the chiller, by lifting it straight up and out of the chiller.

4Inspect the condenser coils. Use a flashlight to check between coil surfaces.

5Clean the dirty coils with a soft brush.

6Flush with cool water or a commercial coil cleaner that is compatible with aluminum alloys. It is recommended that the coil cleaner is sprayed from inside

the cabinet.
