Hi, trying to follow the Owners' Manual instructions for winterizing my Jandy JXi gas fired pool heater but I hit a snag....a screenshot from the manual shows the diagram of the pressure switch connection with a copper tube, indicating I need to disconnect the copper tube from the pressure switch and drain the copper tube for winterizing. But this is inside the heater and very difficult to access. But the tube seems to pass through the sidewall of the heater and attach just after the water inlet, and this would be very easy to access and disconnect. See pic attached. Since it's the same tube, I can't see why I cant disconnect outside....Do you think I could accomplish the same result by disconnecting on the outside, as opposed to the very difficult task of accessing the connection inside. The outside connection is just the other end of the tube that connects to the pressure switch inside. Thanks for any help or advice.

I have never done this with mine. Just taken the drain plug out and had air blown through it.
Thanks, do you live in an area where there are freezing temps in the winter? (I have done the other things you mentioned too).

I am in Maryland so we don't get quite the hard-freezes you get. But it does go well below freezing here. If you do want to drain that line you could just unscrew it from the outside like you showed in the pic.

I think the inside disconnect is to drain the WPS. The WPS may not fully drain with the outside disconnect.
Your risk is needing to replace the WPS if the outside disconnect did not fully drain the WPS and freezing water damaged the WPS.

I think the risk is more for the copper tube than with the WPS itself.
If you disconnect the tube from outside no water will come out as it is airlocked. I just did it today. Water start draining when you disconnect where it is attached to the WPS. It takes 2min to disconnect both ends so this is just what I would do and then put it back together.

I was researching this exact same thing for how I would deal with a loss of power during freezing temps. Everything seems pretty straight forward at the equipment pad (pumps, filter etc.) except this one copper line for the pressure switch mentioned in the manual. Access to this location looks to be a pain!
Actually not Bad. Just have to remove the four screws on the side access panel. Pretty straight forward and the entire procedure wI’ll take 5-10min.
