5.3 Winterizing

WARNING - Failure to heed the following may result in injury or death.
Deactivate all electrical power to chiller before performing hard freeze procedures.
l
CAUTION - Failure to heed the following may result in equipment damage.
Failure to winterize chiller may result in serious equipment damage. Freeze damage is not covered under the
l
chiller warranty.
While the plumbing connections are in the winterized condition (not fully tightened), it is imperative the pool
l
and spa water not be circulated through the chiller. Loss of water through loose plumbing connections may
result in damage to circulating pump, pool and spa structures, and other equipment.
Light Freeze Conditions
There are two freeze conditions requiring chiller attention. A light freeze is when the ambient air
temperature falls below 32 degrees Fahrenheit for less than 8 hours. Typically during light freeze conditions
circulating (moving) water will not freeze. Override time clocks and allow filtration system to run
continuously during light freeze conditions.
Hard Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for more than 8 hours.
In areas where this condition is prevalent and sustained, the chiller MUST be winterized for hard freeze
conditions. Follow the correct procedure depending on the type of heat exchanger found in the chiller.
Identify Exchanger:
1. Deactivate all electrical power to chiller.
2. Deactivate filter pump.
3. Remove front access panel.
4. Identify chiller exchanger from illustrations in this section. Then follow procedure for that chiller's exchanger.
