1. Reinstall front access panel.
2. Disconnect the plumbing to the chiller at connection unions (removal is counter-clockwise).

first, and then a small amount to continue to drain out over a long period.
4. After chiller is fully drained, reinstall front access panel.
5. Partially reconnect plumbing connection unions.
6. Winterizing is complete.
7. When ready to use chiller again, hand-tighten connection unions. Reconnect electrical
power, and set the operating mode on the chiller. Activate filter pump.

3. Place a garden hose into the inlet side of the chiller; wrap a clean rag around the hose to
form a temporary seal.
4. Turn on the garden hose water supply.
5. Allow water to run through the heat exchanger for 2-3 minutes; fresh water should be seen
exiting the pool's out-port.

to form a temporary seal.
7. Turn on the garden hose water supply.
8. Allow water to run through the heat exchanger for 2-3 minutes; fresh water should be seen
exiting the pool's in-port.
9. Place an air hose into the pool inlet of the chiller; wrap a clean rag around the hose to form a temporary seal.
10. Push all water from the water circuit using compressed air at approximately 50 psig. The residual water should
be forced out of the chiller pool outlet.
11. Allow compressed air to blow into the chiller inlet for at least 15-20 seconds after the water stops coming out.
12. Repeat process on the outlet side.
13. Partially reconnect plumbing connection unions.
14. Winterizing is complete.
