START UP

WATER FLOW START-UP

Chiller with Pump

It is important to check the pump rotation on the three phase units. Remove the lower side panel to expose the

pump. Turn the pump power switch to the “ON” position for a few seconds. Observe the motor shaft to ensure

that it is turning in the direction indicated by the arrow located on the pump housing. If the rotation is incorrect,

reverse two of the three incoming power supply leads at the terminal strip. After changing the leads, check the

pump rotation.

NOTE: Running the pump in reverse for more than a few seconds will result in permanent

pump damage.

After ensuring that the system piping is free from obstruction and that all valves are open, turn the pump power

switch to the “ON” position. The pump power indicator should illuminate, indicating that the pump is operating.

All Chillers with pumps are provided with a pressure regulating valve on the pump discharge. This valve is pre-

set at the factory to ensure that system pressure does not exceed the capabilities of the pump motor and/or pip-

ing. If this valve requires adjustment, please contact the factory for proper setting procedure and pressures.

A flow meter and throttling valve can be added in the chiller inlet line in order to monitor and/or adjust the flow

rate through the Chiller.

Once the flow has been established, the thermostat can be adjusted to the desired set-point.

adjustment.

THERMOSTAT ADJUSTMENT

Standard Thermostat

The following procedure should be followed to adjust the standard thermostat:

1. Push the “SET” button located to the right of the digital display. The current set-point will be displayed.

2. While holding the “SET” button, push the “UP” or “DOWN” button until the desired set-point is displayed.

3. Release “SET” button. The display will show the system water temperature. The set-point can be viewed at

any time by pressing the “SET” button.

The thermostat has a range that has been preset at the factory. The range is 40F (5C) to 100F (38C). If

operation outside of this range is required, please contact the Remcor Technical Service Department.
