Winterizing; Restarting Your Spa In Cold Weather - Sundance Spas Hawthorne Owenrs Manual

11.7 Winterizing

Your Sundance® spa is designed to automatically protect itself against
freezing when operating properly. During periods of severe freezing tem-
peratures, 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 22-24).
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. For expert winterization of your spa, contact
your authorized Sundance dealer. In emergency situations, damage
can be minimized by taking the following steps:
1. Follow the directions on page 26-27 for draining the spa.
2. 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.
3. When the water level ceases to drop, use whatever means available
to remove any remaining water from the footwell.
4. Turn off power to the spa.
5. Remove the equipment-side cabinet panel and locate the drain
plugs in the front of the pump(s) (Figure-A, page 11). 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 proce-
dure. Use a wet/dry vacuum or other means to keep this from flood-
ing the equipment compartment. Replace the pump drain plugs.
6. Re-install cabinet side panels and cover spa so that no casual mois-
ture can enter into it.
7. Consult your authorized Sundance dealer if you have any questions
regarding winter use or winterizing your spa.

11.8 Restarting Your Spa in Cold Weather

If you want to start up your spa after it has sat empty for a time in
freezing temperatures, be aware that the water remaining in certain
sections of the piping may still be frozen. This situation will block water
flow preventing the spa from operating properly and possibly damaging
the equipment. We recommend you consult your authorized Sundance
dealer for guidance before attempting to re-start your spa under these
conditions.
