Running the pump alone for low ambient flow protection or during commissioning.
To run the pumps alone without operating the compressors, the following procedure is carried out:
1. Set the remote unit ON / OFF to the OFF position (Open Circuit).
2. Remote pump ON / OFF to ON position (Closed Circuit).
3. Turn the unit ON by display through the microprocessor.
The pumps on the chiller will start. Cooling will not be enabled until the remote unit ON / OFF is to the ON position.
This method is used to ensure that there is water flow through the chiller during periods of unit shut down.
To reinstate cooling the unit remote ON / OFF is to be Closed.
