HotSpring Spa Solana/Hot Spot Pressure Switch. Reverse the removal procedure to install the pressure switch in the control box. NOTE: Wrap one piece of Teflon tape (in the opposite direction of the threads) three times around the pressure switch threads before installation. When screwing the new pressure switch into the heater, DO NOT use pliers, grasp the body of the pressure switch and hand tighten only. After you are finished with the installation, switch the jet pump to high speed and check the pressure switch for leaks.
