Panel maintenance
The panels do not require any special maintenance. To clean them,
just wipe them with a clean cloth and a neutral detergent solution.
ATTENTION: do not direct jets of water against the panels,
since electro-mechanical parts are located behind them.

Winterizing

I
Your Jacuzzi Premium spa is designed to automatically protect
®
itself against freezing when operating properly.
I D
uring periods of severe freezing temperatures, you should
check periodically to be certain that the electrical supply to the s-
pa has not been interrupted.
I
In extreme cold weather, choose the F3 "Standard" skim-
ming/heating mode to prevent freezing.

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 author-
ized dealer.
In emergency situations, damage can be minimized by taking the
following steps:
- Follow the directions for draining the spa.
- Get the water out of the recessed seating areas and footwell.
- Turn off power to spa.
- Remove the side panels and locate the drain plugs of the
pumps. Remove these plugs to allow the water to drain out of
the pumps and heater.
Use a vacuum or other means to keep the water from flood-
ing the system compartment.
- Replace the drain plugs.
- Loosen the hose clamp on the circulation pump intake behind the
electrical box, pull the hose off and drain it. Reinstall hose and clamp.
- Re-install cabinet panels and cover spa with the insulating cover.

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, check whether the water remaining in
certain sections of the piping is still frozen: this situation may
block water flow preventing the spa from operating properly and
possibly damaging the equipment. We recommend you consult
your dealer for guidance before attempting to restart your s-
pa under these conditions.
Water quality maintenance
Maintaining the quality of the water within specified limits will
serve to enhance your enjoyment and prolong the life of the sys-
tem. It is a fairly simple task, but it requires regular attention be-
cause the water chemistry involved is a balance of several factors.
A careless attitude in regard to water maintenance will result
in poor and potentially unhealthy conditions for soaking and
may even damage your spa.
For specific guidance on maintaining water quality, consult your
dealer who can recommend appropriate chemical products for
sanitizing and maintaining your spa.
CAUTION: Never store spa chemicals in the compart-
ments for chemicals which are located under the spa.
pH Control
pH is a measure of relative acidity or alkalinity of water and is
measured on a scale of 0 to 14. The midpoint of 7 is said to
be neutral. Above this value the water is alkaline and below
it, it is acidic.
IT IS VERY IMPORTANT TO MAINTAIN A SLIGHTLY AL-
KALINE CONDITION OF 7.4 to 7.6.
A low pH will be corrosive to metals in the spa equipment. A high
pH will cause minerals to deposit on the interior surface (scal-
ing); in addition, the ability of the sanitation agents to keep the
spa clean is severely affected as the pH moves beyond the ide-
al range.
Sanitizing
To destroy bacteria and organic compounds in the spa water, a
sanitizer must be used regularly.
There are many suitable additives for the spa. Some are necessary
to compensate for out-of-balance water, some aid in cosmetic wa-
ter treatment and others simply alter the feel or smell of the water.
Your dealer can advise you on the use of these additives.
CAUTION: Do not use chlorine tablets (Trichlor) in your
spa: this chemical can have an extremely corrosive effect
on certain materials in the spa. Damage caused by use
of this chemical, or improper use of any chemicals, is
not covered under the spa's warranty.
Ozonator (optional)
If you have elected to have your spa equipped with the ozone
system, you will find that your water stays fresh and clear with
significantly less chemical sanitizer usage.

Summer mode
When the actual spa water temperature reaches up to 1 °C
above the set temperature, the spa goes into "summer mode."
The circulation pump will turn off automatically to avoid adding
additional heat to the water, eventually creating an overheat
condition. (This setting cannot be programmed by the user).
N.B.: The summer mode does not take effect until the spa water
temperature reaches 35 °C. This condition is more likely in ex-
