2. If freezing temperatures are encountered while the system is idle, carefully drain the cooling
water from the cooling tower, condenser, condenser pump, and the chilled water system-
chilled water pump and coils. Open the drains on the evaporator and condenser liquid heads
to assure complete drainage. Drain the Variable Speed Drive cooling system.
3. On the SETUP Screen, disable the clock. This conserves the battery.
4. Open the main disconnect switches to the VSD, condenser water pump and the chilled water
pump. Open the disconnect on the side of the Power Panel to disconnect the storage battery.
Ensure the control center is powered off.
Restart after prolonged shutdown
The chiller has a start inhibit limit for storage battery minimum voltage below 12.8 VDC when
