OCATION
Install the Chiller indoors in a well ventilated area where ambient temperatures will never fall below 50
o
110 F. To obtain optimum cooling capacity, the ambient temperature should be 80
Standard CH Chillers have air-cooled condensers. On air-cooled units it is important that the air intake and discharge
are not obstructed. Avoid hot air discharge from other equipment or enclosed areas where heat build-up could cause
a significant rise in ambient temperatures. A minimum of two feet of space on all four sides of the Chiller will be
sufficient to prevent obstruction.

LECTRICAL
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 upper rear of the chiller, includes a four-terminal strip for power supply connections The DATA
PLATE, located beside the junction box, indicates the actual phase, voltage and amperage for each chiller.
!
CAUTION:
On 3-phase applications, it is important that the rotation of the pump, when supplied, is correct. Running the pump in
reverse for more than a few seconds will result in permanent pump damage. When the pump is running, shaft rotation
must match the direction indicated on the pump housing. If the rotation is incorrect, reverse two of the three incoming
power supply leads. The Phase Protection/3-Phase Monitor Option prevents the pump from operating backwards.
See the option description.
