Winterize a spa

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 electrical supply to the hot tub has not been interrupted. In extreme, bitter cold weather (less than -20°F) verify standard mode is selected (Section 11.3, page 37) 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.

CAUTION: Turn off power to hot tub.

1. Follow the directions on page 44 for draining the hot tub.

2. As the water level drops below the seats, momentarily turn power back on press blower button to blow water out of air blower lines (if you have a air blower system 880 series) turn power off then 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. Remove the equipment-side cabinet panels and locate the drain plugs in the front of each pump (Figures A and B, page 12). 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.

5. Loosen hose clamp at bottom of heater (Figures A and B, page 12) and pull hose off of heater fitting (twist the hose back and forth while pulling downward. Tip hose down and allow draining, and then reinstalling hose and clamp.

6. Re-install cabinet side panels and cover hot tub so that no moisture can enter into it. Consult your Sundance Spas dealer if you have any questions regarding winter use or winterizing
