    Jandy LXi Air Pressure Switch Connections

    Hi everyone,

    I just replaced my water temp sensor in my LXi 250 heater, and as I was putting the parts back together, the two hoses that connect the air plenum to the air pressure switch came loose.

    Is there a specific port that these two hoses go into, or is it just a loop? Just want to make sure before I plug them in the wrong way and blow everything up...

    Thanks!

    Aaron

    No specific port. It just monitors air pressure of the two. The switch requires bot to have the correct pressure in order for the system to work.

    I did end up finding something online in a troubleshooting guide that said the front port (+ side) is for the front hose from the air plenum and the rear port (- side) is for the rear/side hose from the air plenum. Not sure if it's actually necessary or true, but I did it that way and the heater works and I still have my eyebrows...
