HOW TO Replace the Heater
3• With the help of an open-end wrench,
disconnect the heater wires (remove
only the two upper nuts). Do not
touch the large nuts!
4• Loosen the two heater nuts and
release the heater from under the
spa.
7• Gently reconnect the heater wires
with an open-end wrench, while
holding the lower nuts with another
wrench to avoid damaging the
contact pins.
8• Verify if the heater is properly
connected to the board.
9• Reinstall the pressure switch and
reconnect the wires (in no particular
order).
5• Slide the new heater into place
and fix it to the power box using
the two nuts.
The two heater-fixing nuts must be
properly tightened because they also
serve as a current collector in case of
heater failure.
6• Reinstall the high-limit sensor and the
plate.
Tighten the two wing nuts just enough
to hold the sensor plate in place.
