A&S service department closed my pool for the 1st time yesterday. When they were about to leave, I asked if they separated the couplers on my Heat Siphon heat pump. Guy #1separated the top one and asked Guy #2 if he had already done so, he replied yes and so guy # 1 put it back together. They had pressurised the system prior to that point. I then noticed that they didn't remove the SWCG cell. I asked why not and guy # 1 said he has never seen one get freeze damage (mind you neither one of them looked toi be over 19 years old). Then Guy #1 said if it makes me feel better, I (me) can remove it and store it inside. They also did not remove the pump motor and said it will not be damaged by the elements.
I don't have any fancy water features, just a dedicated return line for my Polaris 360. 2 additional returns on the walls, and 3 returns on the floor, and a main drain, 2 skimmers. My heat pump is plumbed in after the filter and before the SWG so that the water gets charged with chlorine as it returns to the pool. The floor returns weren't plugged, just air held in place by setting the valves on off. The main drain, I believe was done the same way. I wasn't home for the process cause I got stuck at work. The skimmers, wall returns, Polaris return were plugged. My questions:
If I remove the SWG cell, will the air come out from the floor returns/main drain and allow freeze damage?
Also, by Guy #1 separating the heat pump coupler, did he break the pressere seal for the floor returns?
Will the SWG cell survive in the winter if not removed?
I am concerned with the warranty. Thanks for your support.
