Light Freeze Conditions
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 (or moving) water will not freeze. Temporarily activate the
filter pump for continuous operation 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. See "Access Panels"
4. Identify heat exchanger from illustrations in this
section. Then follow procedure for the appropriate
heat exchanger.

5. Reinstall front access panel.
6. Disconnect the plumbing to the chiller at connection unions (removal is counter-clockwise).
7. Allow water to drain completely from the chiller. Expect to see a lot of water drain out at first,
and then a small amount to continue to drain out over a long period.
8. After chiller has fully drained, partially reconnect plumbing connection unions.
9. Winterizing is complete.
10. When ready to use chiller again, hand-tighten connection unions. Reconnect electrical power,
and set the operating mode on the chiller. Activate filter pump.

7. Allow water to drain completely from the chiller. Expect to see a lot of water drain out at first,
and then a small amount to continue to drain out over a long period.
8. Place an air hose into the pool inlet of the chiller; wrap a clean rag around the hose to form a
temporary seal.
9. Push all water from the water circuit using compressed air no stronger than 50 psig. The
residual water should be forced out of the chiller's water outlet. Allow compressed air to blow
into the chiller inlet for at least 15-20 seconds after the water stops coming out.
10. Repeat process on the outlet side of the chiller.
11. Partially reconnect plumbing connection unions.
12. Winterizing is complete.
13. When ready to use chiller again, hand-tighten connection unions. Reconnect electrical power, and set the operating
mode on the chiller. Activate filter pump.
