Pump Rotation Direction Indicator
This section applies chillers with CM5-4 pump only
Purpose: The pump motors must rotate the correct direction to provide proper pressure and flow.
Haskris confirms proper rotation direction prior to shipment. The phase monitor is configured to be
the primary check on rotation direction. Typically, no other verification is necessary for the pump
rotation direction.
However, if there is any question about the rotation direction of the pumps there is an indicator on
the motor.
Location: The indicator is attached to the endcap of the motor. The indicator is not permanently
attached. If you do not see it, someone may have removed it intentionally or by accident.
Operation: Only check the indicator when the pump is running. If the indicator shows black, the
rotation direction is correct. If the indicator shows white, the rotation direction is reversed.
