To drain the chiller for storage or transport:

1Rotate the chiller’s drain valve counterclockwise. If using chemicals or additives with your process coolant, observe local disposal laws and regulations.

Water level gauge

Fill/drain port

To Process outlet

2Close the chiller’s drain valve by turning it clockwise once final evacuation of all process coolant is complete.

IMPORTANT: Drainage procedures must be done prior to shipment or outdoor storage of the unit. If not, freezing damage can occur.

IMPORTANT: Ensure long-term storage environments are above freezing temperatures. If not, allow the chiller to thaw for several hours before returning it to operation or fill the chiller’s internal piping with a high mixture of glycol to water during storage.
