Maintaining The Synthetic Cabinet; Winterizing - Sundance Spas 780 series Owner's Manual

11.6

Maintaining The Synthetic Cabinet

Your new spa's synthetic cabinet requires little or no maintenance of
any kind. To clean, simply wipe cabinet with a clean towel and mild soap
solution.
CAUTION: Never spray cabinet with a garden hose for
any reason since this action may induce an electrical
short in the spa's electrical equipment.
11.7

Winterizing

Your Sundance spa is designed to automatically protect itself
against freezing when operating properly. During periods of
severe freezing temperatures, you should check periodically to
be certain that the electrical supply to the spa has not been interrupted.
In extreme, bitter cold weather less than -20°F (-29°C), choose the F3
"Standard" filtration/heating mode and program the circulation pump to
run for 24 hours to prevent freezing (pages 29 and 30).
If you do not intend to use your spa, or if there is a prolonged power
outage during periods of severe freezing temperatures, it is important
that all water be removed from the spa and equipment to protect
against damage from freezing.
Expert winterization of your spa is highly recommended, contact your
authorized Sundance dealer. In emergency situations, damage can be
minimized by taking the following steps:
CAUTION: TURN OFF POWER TO HOT TUB!
1. Follow the directions on pages 36-37 for draining the spa.
2. Turn the massage/diverter selector(s) into the middle combo
position to allow the water in the plumbing lines to drain (page
26).
3. Turn the waterfall valve(s) to the open position to allow the water in
the plumbing lines to drain (page 28).
4. As the water level drops below the seats, use whatever means
necessary to get the water out of the recessed seating areas and
into the footwell, such as a wet/dry vacuum.
5. When the water level ceases to drop, use whatever means available
to remove any remaining water from the footwell, such as a wet/dry
vacuum.
6. Remove the equipment-side cabinet panels and locate the drain
plugs in the front of the pump(s) (Figure A, page 16). Remove
these plugs to allow the water to drain out of the pumps and heater.
Note: Approximately one to two gallons will be released during this
procedure. Use a wet/dry vacuum or other means to keep this from
flooding the equipment compartment. Replace the drain plugs.
