INSTALLATION INSTRUCTIONS
L
OCATION
Locate the chiller indoors in a well ventilated area with ambient temperatures in the range of 65° to 100° F. Allow
a minimum of six inches of clearance around the chiller for proper air circulation. Avoid hot air discharge from
other equipment or enclosed areas where heat could build up and cause a rise in ambient temperature.
P
LUMBING
Follow standard plumbing practices and local codes in making water connections. Piping that is exposed to high
ambient temperatures may need to be insulated to prevent condensation and/or significant liquid heat gain. Hook
up the outlet of the chiller but delay making the final connection to the inlet of the chiller until the system is filled
with water (see START–UP/OPERATION).
E
LECTRICAL
All wiring must conform to the National Electric Code and any applicable local codes. The chiller must be:
1.
Permanently wired by means of conduit from the junction box in 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. 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
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 illuminates indicating power to the Unit and the pump
operates, the thermostat can be adjusted to the proper setpoint.
