INSTALLATION
SPARE PARTS AND SERVICE ADVICE
f Replace the transformer and rewire the spare part transformer
as before.
Pressure switch
It is possible for the pressure switch to be become so blocked with
residue or dirt that it does not function and allow the heater to turn
on.
f Disconnect the heater from the power supply.
f Check for continuity across the poles of the switch with water
pressure on the heater. The water pressure needs to be more
than 3 psi (0.21 bar). If there is continuity the pressure switch is
not the cause.
f If there is no continuity, drain the water from the heater, re-
move the wires from the switch. Mark the wires with the switch
pole designation. Pole nb. 1 needs to be connected to the
transformer.
f Remove the switch using an open-end wrench.
f Check for water leaks.
f Rewire the switch.
Delay switch
f Disconnect the heater from the power supply.
f Mark the wires on both sides of the delay switch.
f Contact 3 wire need to come from the contactor coil A2 port.
Remove the old delay switch from the support bar and replace
it with a spare part.
f Rewire as before.
Set the delay time setting to 1. It means the delay time is 1 minute.

f Clip the wires to the light. Pop the light socket out of the hole in
the enclosure.
