Freeze Protecting Your System; System Start-Up After Freezing Conditions - FAFCO Connected Tube CT Owner's Manual

Freeze Protecting Your System

The installations most prone to freeze damage include systems that have collectors below the pool
water level and systems installed in hard freeze locations. All systems, when shut down for the win-
ter, must be checked to ensure that they are completely drained.
It is strongly suggested to perform a winterization and spring tune-up for your Connected Tube
CT system annually so that you don't void the warranty.
If you choose to winterize your system yourself, follow these steps:
1. Ensure that the pump is not running.
3. Open manual drain valves if equipped.
4. Remove Vacuum Relief Valve and end caps at the lowest collector and store for winter
5. Let the system drain completely for a few minutes.
6. Close the solar isolation valves.
7. Ensure the diverter valve is set to bypass the Connected Tube CT System and that the automation
equipment is properly decommissioned for winter use.
8. Ensure that the diverter valve is turned to the thermal off position and turn on the pool equip-
ment. Let the system run for at least 5 minutes while checking to make sure no water is coming
out of the end cap area of the collectors.
