Winterizing

Your Sundance hot tub 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 electri-
cal supply to the hot tub has not been interrupted. In extreme, bitter
cold weather (0°C) verify standard mode is selected (Section 12.1) and
program the circulation pump to run for 24 hours to protect the hot tub
from freezing.
If you do not intend to use your hot tub, or if there is a prolonged power
outage during periods of severe freezing temperatures, it is important
that all water be removed from the hot tub and equipment to protect
against damage from freezing.
Expert winterization of your spa is highly recommended, contact
your authorized Sundance Spas dealer. In emergency situations,
damage can be minimized by taking the following steps:
CAUTION: TURN OFF POWER TO HOT TUB!
1. Follow the directions (Section 13.3) for draining the hot tub.
2. Turn the massage/diverter selector(s) to the middle combo position
to allow the water in the plumbing lines to drain, see page 32.
3. Turn the waterfall valve(s) to the open position to allow the water in
the plumbing lines to drain, see page 33.
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 33.
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 panels and locate the drain plugs
in the front of each pump (Figures A and B, page 14). Remove
these plugs to allow the water to drain out of the pumps and heater.
Note: Approximately 1 to 2 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.

and pull hose off of heater fitting (twist the hose back and forth while
pulling downward. Tip hose down and allow to drain, then reinstall
hose and clamp.
9. Loosen hose clamp at bottom of CLEARRAY® system and pull hose
off of CLEARRAY fitting (twist the hose back and forth while pulling
downward). Tip hose down and allow to drain, then reinstall hose
and clamp. Remove the cover of the CLEARRAY system to access
the UV bulb and quartz tube. Remove and store the UV bulb in a
