cold weather (less than -20°F) verify auto-heating is set for 24-hour
operation (Section 13.5 Programming The Primary Filter Cycle, page 64)
and that auto-heating is selected (Section 13.2 Auto-Heating or Section
13.3 Programmable Heating Mode, page 60) to protect against damage
to the spa.
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.

your authorized Jacuzzi dealer. In emergency situations, damage can
be minimized by taking the following steps:
CAUTION: TURN OFF POWER TO SPA.
1. Follow the directions on page 68 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, see page 54.
3. Turn the waterfall valve to the open position to allow the water in the
plumbing lines to drain, see page 54.
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. 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.
6. Remove the equipment-side cabinet panels and locate the drain
plugs in the front of each pump (Figure A, page 12). 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
ooding the equipment compartment. Replace the drain plugs.
7. Loosen hose clamp at bottom of heater (Figure A, page 12) and pull
hose off of heater tting (twist the hose back and forth while pulling
downward). Tip hose down and allow to drain, then reinstall hose
and clamp.
8. Loosen the hose clamp on the circulation pump (if equipped) intake
behind the control box (Figure A) 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.
9. Re-install cabinet side panels and cover spa so that no casual
moisture can enter into it.
Consult your Jacuzzi dealer if you have any questions regarding winter
use or winterizing.
