CH Series Chiller Operator’s & Installation Manual

1. Permanently wired by means of conduit from the junction box on the rear of the chiller cabinet to a

properly fused disconnect of proper amperage or;

2. Wired to a properly rated power cord and plugged into an outlet with appropriate disconnect and

amperage rating.

START-UP/OPERATION

Before the Unit can be operated, it is important that the circulating system be filled with water (See Fluid

Recommendations page). On systems with a reservoir, ensure that the drain plug is in place and the plug is

secure. Fill the reservoir through the fill port with clean water. The water level sight glass on the front panel will

indicate “Full” when enough water has been added. Once full, make the final connection to the inlet and outlet of

the chiller. On system without a reservoir, the pump should be primed before operation. Attach a water source to

the inlet of the chiller and fill the Unit with clean water. The system is filled when the water can be seen flowing at

the chiller outlet. Once full, make the final connection to the inlet of the chiller.

Turn the power switch to the “On” position. The switch will light indicating power to the Unit and the pump

operates, the thermostat can be adjusted to the proper setpoint.

When the flow rate to the process is critical, a flow meter and valve should be installed in the line in order to

obtain the proper flow rate.

Once these start-up procedures are complete, the chiller is ready for standard operation.

NOTE: Never operate the chiller with enclosure panels removed.

Always use the illuminated switch to turn off the chiller when it is not being used.

Always ensure that all air inlets and outlets are free of obstructions.
