1. Disconnect the plumbing to the chiller at connection unions (removal is counter-clockwise).
2. 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.
3. Place an air hose into the pool inlet of the chiller; wrap a clean rag around the hose to form
a temporary seal.
4. Push all water from the water circuit using compressed air no stronger than 50 psig. The
residual water should be forced out of the pool outlet. Allow compressed air to blow into
the chiller inlet for at least 15-20 seconds after the water stops coming out.
5. Repeat process on the outlet side of the chiller.
6. Partially reconnect plumbing connection unions.
7. Winterizing is complete.
8. When ready to use chiller again, hand-tighten connection unions. Reconnect electrical power, and set the
operating mode on the chiller. Activate filter pump.
