Freeze Prevention

It's important to take care of your solar heating system. Below are freeze preventions steps:

1. Turn off the solar heating system at controller (if a manual system turn 3-way valve into the solar off position)
2. Turn off the pool pump
3. Open solar drain valve (if you have a manual draining system)
4. Remove endcap on solar panel and let system drain for a hour
5. If you can not get on your roof wait 2 hours for the VRV to drain your panels
6. Close isolation valves (ONLY AFTER SYSTEM IS DRAINED)
7. The pool pump, filter, and pool sweeps can now be used while remaining isolated from the solar system.

Please note: Operating your solar system during freezing conditions IS NOT an approved freeze-protection method
