that the shaft is rotating in the direction of the arrow indicated on the pump housing. If the rotation is incorrect,
reverse two of the three incoming power supply leads at the terminal strip.
NOTE: Operating the pump in reverse for more than a few seconds will result in permanent pump dam-
age.
All Chillers with pumps and tank are supplied with a pressure regulating valve on the pump discharge. This
valve is preset at the factory to ensure that system pressure does not exceed the capabilities of the pump motor
and/or piping. If this valve requires adjustment, please contact the REMCOR Service Group for the proper set-
ting procedure and pressures.
Process liquid flow can be adjusted VIA a throttling valve and flow meter installed in the Chiller outlet line.
Once the flow has been established, the thermostat can be programmed to the desired set--point.
Process Liquid Flow, Units Without Reservoir (Optional)
Follow standard plumbing practices and local codes in making liquid connections. The Chiller inlet and outlet
connections are 3/4”. 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.
Proper priming of the liquid lines is essential to prevent pump cavitation. Be certain all air has been purged from
the lines before operating the pump for an extended period of time. Be sure to remove any loops in the lines that
may trap air. The pump must have a supply of water with the level of the liquid above the inlet of the Chiller.
The supply tank must feed the Chiller from the side of the tank below the water level (see Figure 5).
