12.8 Winterizing
Your Jacuzzi Premium spa is designed to automatically protect itself against
freezing when operating properly. During periods of severe freezing tempera-
tures, 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), reset the filter cycles for 24-hour operation to protect the spa
(i.e. four 6-hour cycles). 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 Jacuzzi
Premium dealer. In emergency situations, damage can be minimized by tak-
ing the following steps:
1. Follow the directions on page 35 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 panels and locate the drain plugs
in the front of the pump(s) (Figure-A, Page 10). 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 drain plugs.
6. Loosen the hose clamp on the circulation pump intake behind the con-
trol box (Figure-A, Page 10) 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.
7. Re-install cabinet side panels and cover spa so that no casual moisture
can enter into it.
Consult your Authorized Jacuzzi Premium dealer if you have any questions
regarding winter use or winterizing.
12.9 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
