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 32°F (0°C), program the
primary filtration cycle to run for 24 hours to prevent freezing (page
31).
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 40-41 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 27).
3. Turn the waterfall valve(s) to the open position to allow the water in
the plumbing lines to drain (page 29).
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. Open all the air controls and leave them open until you resume use
of the spa, page 28.
6. 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.
7. Remove the equipment-side cabinet panel(s) and locate the drain
plugs in the front of the pump(s) (Figure A, page 15). 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.
8. Loosen the hose clamp on the circulation pump intake behind the
control box (Figure A, page 15) and pull the hose off (twist hose
back and forth while pulling outward). Tip hose down and allow to
drain, then reinstall hose and clamp.
