Drain Connection
To drain the chiller for storage or transport:
1 Rotate the chiller’s drain valve counterclockwise. If using chemicals or
additives with your process coolant, observe local disposal laws and regulations.
2 Close 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.
