!
CAUTION:
IF FREEZING CONDITIONS EXIST DURING CHECKOUT AND FLUSHING
PROCEDURES, THE FLUSHING PROCEDURE AND SUBSEQUENT FILL WITH FINAL
GLYCOL/WATER MUST BE FINISHED BEFORE STILL WATER IS ALLOWED TO
REMAIN IN HEAT EXCHANGER. IF PROCEDURE CANNOT BE FINISHED, CARE
MUST BE TAKEN TO PREVENT WATER FROM FREEZING IN OUTSIDE COOLING
SYSTEM EQUIPMENT. IF WATER REMAINS IN OUTSIDE EQUIPMENT LONG
ENOUGH TO FREEZE, THE UNITS WILL BE DAMAGED. PUMP A MIXTURE OF
GLYCOL/WATER INTO OUTSIDE EQUIPMENT TO PREVENT DAMAGE.
NOTE:
The system cannot be filled to capacity at this time. Water must be added as pipes
and equipment fill up upon initial pump turn on. The reservoir tank is equipped
with a level switch which will shut the pump off if a low water level occurs.
