The pressure switch is preset at the factory for
activation at 2 psi (14 kPa). Do not adjust the pressure
switch if the heater is installed more than 15 feet (4.57
m) below the pool surface. Consult your local Jandy
representative for recommendations.
On some installations, the piping from the heater
to the pool is very short. The back pressure could be
too low to trigger the pressure switch. If this happens,
it may be necessary to install a directional tting or
elbows where the return line enters the pool. This will
increase back pressure enough for the heater to operate
properly.
