Winterizing
Damage will occur if water is allowed to freeze inside
the heater. Normally the heater will drain when the spa
is drained. If the heater is positioned lower than the
spa a drain valve must be added at the heater inlet.
The water must be drained from the heater and the
main disconnect switch shut off.
Filter
CAUTION: Do not allow filter to become clogged to
the extent that cycling of the pressure switch occurs.
This can result in accelerated wear of the magnetic
contactor. Contactor damage caused by dirty filter is
not covered by warranty.
