Daikin Magnitude Magnetic Bearing Centrifugal Chillers(Magnitude WME-C): During Seasonal Shutdown Maintenance

The following Maintenance Procedures should only be maintained by qualified service personnel.
Seasonal Shutdown
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. Water permitted to remain in the piping and vessels can rupture these parts if subjected to freezing temperatures. Dry air blown through the vessels will aid in forcing all water out.
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.
