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 to close at too low of a flow
can damage the appliance. Adjust the switch
to turn the heater off, not on.
The pressure switch is preset at the factory for
activation at 3 psi (21 kPa). This is the minimum setting
for the water pressure switch and works for all basic
installations. Only adjust the water pressure switch if
the heat pump does not operate
when the proper flow
is applied to unit
or if the heat pump does not shut
off when the filter pump is off. Occasionally, unusual
plumbing configurations or necessary restrictions in
the plumbing may cause pressure sensing problems. In
these rare situations, the plumbing system configuration
may require adjustment of the water pressure switch.
Adjustment of the pressure switch may be necessary
if any part of the filter system piping is 3 feet (1 m) or
more above the top of the heat pump jacket.
Do not adjust the pressure switch if the heat pump is
installed more than 5 feet (1.5 m) above or 10 feet
(3 m) below the pool surface. Consult your local
Zodiac
®
dealer for recommendations.
