5.4 Water Pressure Switch Adjustment
CAUTION
The water pressure switch should be adjusted to turn
the heater off when the pump is off. Setting the switch
tocloseattoolowflowcandamagetheappliance.
Adjust the switch to turn the heater off, not on.
The pressure switch is preset at the factory for activation
at 2 psi (14 kPa). If the heater is installed below the
surface level of the pool, more than two feet above the
pool level, or any time the pressure is measured at 1 psi
or greater with the system pump off the pressure switch
setting must be adjusted.
Location of the heater above or below the pool water
surface can also affect the operation of the switch. The
factory installed switch can accommodate elevations not
exceeding 6 feet above the pool water surface or 11 feet
below pool water surface. If the heater water connections
are outside this range Consult your local Zodiac
representative for recommendations.
Make sure the pool filter is clean before making any
pressure switch adjustment. A dirty filter will restrict the
water flow and the pressure switch cannot be adjusted
properly.
To adjust the water pressure switch:
NOTE: It is recommended that a Pressure Release Valve
(PRV) be installed prior to taking any of the steps
below. See section 5.7
1.
Set the heater control to the “OFF” mode.
2.
Remove the header side panel to access the water
pressure switch.
3.
Start the filter pump and confirm by means of a
voltmeter that the pressure switch closes (if the
switch fails to close, replace it with a switch that
has a lower minimum setting).
4.
Set the heater control to either POOL or SPA.
Heater should start.
5. With your fingers, turn the adjustment sprocket
very slowly clockwise until the heater goes off.
