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 ob- structions.

It is also important to direct any hot air discharge from other equipment away from the air intake side of the chill- er. 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.

Electrical Connections

All wiring must conform to the National Electric Code and any applicable local codes.

The “CH”unit 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 dis- connect and amperage rating. The electrical junction box includes a four terminal strip for power supply connec- tions. The DATA PLATE located beside the junction box indicates the phase, voltage and amperage of the chiller.

Process Connections

Follow standard plumbing practices and local codes in making liquid connections. The Chiller inlet and outlet connections are 3/4”--inch FPT couplings. It is recommended that 3/4--inch I.D. or larger flexible hose and tube fittings be used as process connections. 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 tem- peratures should be insulated to prevent condensation and/or significant liquid heat gain.

Once the system has been properly plumbed, it is important that the circulation system be filled with liquid. The reservoir can be filled by removing the fill port cap located on top of the Chiller. After ensuring that the drain is closed, fill the reservoir via the fill port with pure liquid until the liquid level sight glass on the front of the unit indi- cates ”FULL”. The fill port cap should then be replaced prior to operation.
