**FOR ALL TESTS & ADJUSTMENTS UNPLUG THE “HEATER POWER”
CORD**
1) With power to system turned OFF, unplug the Lt. Purple colored Heater
Control cord.
2) Place an Ohmmeter across the pressure switch test points on the cord to
verify a OPEN circuit. If the switch is closed at this point rotate the adjustment
screw clock-wise until the switch reads OPEN.
3) Turn power to the system ON and activate the low-speed pump.
4) Place an Ohmmeter across the pressure switch test points to verify a CLOSED
circuit.
5) If switch is not closed rotate the pressure switch adjustment screw counter-
clockwise until the Ohmmeter indicates a CLOSED circuit.
6) Re-connect the heater control cord.
7) Now test for proper operation of the system with the pump running and with
the pump off, no error codes should be present in either instance.
IMPORTANT: After any pressure switch adjustment, it is important to test the
control by turning on the pump low speed and heater. While operating, unplug
the pump, the heater must turn off. If the heater stays on, plug the pump back
in and readjust the pressure switch to achieve proper operation.
