SYSTEM SHUTDOWN
1.
Disable the solar pool heating function on your controller and shut pump(s) off to be safe.
2.
Open the system drains to allow fluid to drain from the solar loop. Leave drains open.
Ensure that water is draining to an approved/safe location.
3.
Once all water has drained out of the solar loop shut the manual isolation
valves on the main supply and return lines. These valves are typically
location on the lines running up the wall and above the drains.
4.
During the period of winterization keep the manual isolation valves shut and
the drains open. The pool pump may run to protect other equipment from
freezing but no water should be able to enter the solar loop during this time.
5.
If water is observed coming out of the drains this indicates that the solar function
is still enabled in the controller, an isolation valve is open, and/or an isolation valve
is not sealing properly. Check the controller and valves and repeat steps 1-4 again.
