OCATION OF
HILLER
!
CAUTION:
The chiller must be located near a properly grounded electrical outlet. the circuit should be fused and no other
electrical appliance should be connected to the circuit. All electrical wiring must conform to national and local
electrical codes.
The chiller must be located in a well ventilated, indoor area where ambient temperatures will remain above 40° F (5°
C) and will never increase above 100° F (38° C). To obtain optimum cooling capacity, the ambient temperature should
be at or below 80° F (27° C).
It is very important that the air intake and discharge sides of the chiller are not obstructed by other free standing
objects. A minimum of two feet of space on all four sides of the chiller will be sufficient to prevent air flow obstructions.
It is also important to direct any hot air discharge from other equipment away from the air intake side of the chiller.
Condenser air entering the "CH" unit should be below 100° F (38° C).Condenser air temperatures above 100° F (38°
C) can cause the high pressure safety control to shut down the unit.

ONNECTIONS
!
CAUTION:
All wiring must conform to the National Electric Code and any applicable local codes. The chiller must be permanently
wired by means of electrical conduit to a properly fused disconnect of proper amperage or wired to a properly rated
power cord and plugged into an outlet with the appropriate disconnect and amperage rating. The electrical junction
box, located on the back panel of the chiller, includes a four terminal strip for power supply connection. Refer to Figure
2 for the CH250 model and Figure 3 for the CH251 model. The data plate, located next to the junction box, includes
the actual voltage, phase and amperage of the chiller.
