CH5000 Chiller Operator’s & Installation Manual

ELECTRICAL

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 three 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 results 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.

PLUMBING

Follow standard plumbing practices and local codes in making water connections. The chiller inlet and outlet

connections are 1-inch FPT. Flexible hose and fittings are recommended for plumbing the system. A No. 20 mesh

strainer should be installed on the chiller inlet to prevent foreign particles from entering the system and should be

cleaned monthly. Lines should be routed with as few bends as possible. Prevent lines from running near radiators, hot

water pipes, etc. Any lengths of tubing that are exposed to high ambient temperatures should be insulated to prevent

condensation and/or significant liquid heat loss.

Chiller with Reservoir

The reservoir can be filled by removing the water fill cap located on the upper rear of the chiller (See Fluid

Recommendations section). After ensuring that the drain valve is closed, fill the reservoir via the full port with clean

water until the water level sight glass on the front of the unit indicates “FULL” the fill cap should then be reinstalled

before operation begins.

Chiller without Reservoir

The chiller and system piping should be filled with clean water ensuring that all air is purged from the system.
