Locate the Pressure Switch on the back side of the stainless steel Heater Housing. The gray cable from the switch is connected to J3 (Platinum or Primer/Select) or J9 (Duplex).

Unplug the pressure switch from the circuit board and with a paperclip or pin knife, push out the two pins from the connector. Clip the leads from an OHM-METER onto these two pins.

With the system “OFF” and no voltage to the Pump/Motor the reading of the OHM-METER should be on “OPEN”. If the meter shows the switch as being “CLOSED” adjust the spoked wheel on thenpressure switch counter-clockwise until an “OPEN” condition is read on the OHM-METER.

Start the Spa operation in a “Filter” mode and check the OHM-METER reading for a “CLOSED” switch reading. If the reading shows the switch to be in an “OPEN”, turn the spoked wheel on the pressure switch clockwise until the meter reads “CLOSED” plus a little further to allow for a dirty filter.

Repeat Step #3. The OHM-METER should read “OPEN” with no power to pump/motor. NOTE: Be sure all these adjustments are done in the low “Filter” mode and not the high-speed “Jet” operation. The pump/motor connection can be disconnected by unplugging the side motor connector while testing steps #3 and #4.
