WARNING!
The condenser and evaporator are not self-draining. Where the chiller can be subject to freezing temperatures, the condenser and evaporator must be drained of all water.

Except for freezing conditions, it is desirable to leave water in the vessels to avoid long term exposure to air.
Continuous forced circulation of antifreeze through the vessels is one method of avoiding freeze up.
