4.4 Winterizing

WARNING - Failure to heed the following may result in injury or death.
Deactivate all electrical power to heat pump before performing hard freeze procedures.
l
CAUTION - Failure to heed the following may result in equipment damage.
Failure to winterize heat pump may result in serious equipment damage. Freeze damage is not covered under the
l
heat pump 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 heat pump. Loss of water through loose plumbing connections may
result in damage to circulation pump, pool and spa structures, and other equipment.
Light Freeze Conditions
There are two freeze conditions requiring heat pump 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 heat pump MUST be winterized for hard freeze
conditions. Follow the correct procedure depending on the type of heat exchanger found in the heat pump.
Identify Exchanger:
1. Deactivate all electrical power to heat pump.
2. Deactivate filter pump.
3. Remove front access panel.
4. Identify heat pump exchanger from illustrations in this section. Then follow procedure for that heat pump's
exchanger.
