Winterizing
In areas that have freezing winter temperatures, pool equipment must be winterized to protect against damage. Allowing water
to freeze will damage the sand lter and void warranty.
1. Backwash the sand lter as previously outlined in Section ll and Section lll.
2. Drain the pool according to the pool owner’s manual.
3. Disconnect the two Hoses from the pool and the sand lter.
4. Completely pour the sand out of the tank and dry all components.
5. Store the sand lter in a dry location out of child’s reach.
