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 to prevent freezing (pages 31-32).
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. Turn off power to the spa.
2. Follow the directions on page 37 for draining the spa.
3. Turn the massage/diverter selector(s) into the middle combo position
to allow the water in the plumbing lines to drain, see page 29.
4. Turn the waterfall valve to the open position to allow the water in the
plumbing lines to drain, see page 29.
5. 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.
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 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 pump drain plugs.
8. 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 lamp and quartz tube. Remove and store the UV lamp in a
safe location. Remove and dry off the quartz tube then reinstall it.
Depending on the length of time, consider replacing the UV lamp
when you resume use of your hot tub.
9. Re-install cabinet side panels and cover spa so that no casual
moisture can enter into it.
Consult your authorized Sundance dealer if you have any questions
regarding winter use or winterizing.
