Thread: Universal Pressure Switch

    Universal Pressure Switch

    I bought a Hayward heater late last year, used. I had to replace the pressure switch on it. When I went to the pool place today, the guy sold me a universal switch. I asked him if I had to adjust it at all and he didn't really seem to know much about it. Can someone direct me as to what I need to do when I install this if I need to do anything at all......

    HAXPSA1930 is the switch model from the owners manual. The universal switch is from Allied Innovations and the number is 800120.

    The universal switch looks similar to the original. Check your owner's manual, there should be a section on how to adjust the OEM pressure switch. I'd bet the same procedure would work on the new one.
