Underwater spotlight

Press the key "Light"
the wall of the tub (the LED comes on).
The spotlight will stay on for two hours, but it can be turned
off before that by pressing the key again. Refer to the user's ma-
nual for the operation of the various sequences of colours.
Temporary shutdown of system (stand-by)
This function lets you suspend operation of all system devices for a
period of 60 minutes (this value cannot be changed) so that you
can perform routine maintenance without having to disconnect
the power supply.
CAUTION
If you need to access the electronic parts, parts that are
normally powered, or the rotating parts of the pumps,
you must disconnect the electric power by turning off
the all-pole circuit breaker.
To activate the function, press and hold the "Light"
for about 8 seconds: the display will show the message "Sby"
followed by the number of minutes the function will remain blo-
cked.
This function will end after 60 minutes or by pressing and
holding the "Light" key for about 5 seconds.
NOTES
- If a fi ltering cycles is active, it will restart 40 minutes after the end
of the stand-by condition at the same point it was stopped. This me-
ans that if 1 hour remained when the cycle was stopped, when it
restarts it will operate for this amount of time and then stop.
- If the heater was on when stopped, it is turned off immediately
and water is circulated for 30 seconds in order to cool the heating
element.

Water treatment

The water must be "inviting", that is, clear, limpid and free from tho-
se substances that, accumulating, can create a suitable environ-
ment for the growth and spread of bacteria; for this reason, as well
as being fi ltered continuously, the water must be chemically treated
by using appropriate additives.
There are many products on the market for water disinfection and
they vary in terms of cost and method of use.
The suggestions provided here cover only the general aspect
of a complicated topic such as water treatment. If special
problems or situations occur, it is advisable to contact spe-
cialised companies, who will unquestionably be able to pro-
vide the best solution.

Disinfectants for spas and pools

Certain disinfectants used in large swimming pools, such as ch-
lorine, calcium hypochlorite and sodium hypochlorite, are not sui-
table for spas.
Chlorine tablets permanently stain the methacrylate (af-
ter prolonged direct contact), calcium hypochlorite (normally
available in granules) encourages calcium deposits and sodium
hypochlorite (which is liquid) will permanently damage the
methacrylate if poured onto it directly.
"Chloroisocyanurates" are chloro-organic derivatives that are
more suitable for spas; moreover, these products are particularly
suitable if the spa is located outdoors, as they act as stabilizers
and prevent sunlight from depleting the action of chlorine.
Another type of disinfectant is bromine; this has an advanta-
ge over chlorine, in that it is less of an irritant, has less infl uence
on the pH level and has no smell. Furthermore, unlike chlorine,
bromine does not separate into "combined" and "free" forms.
Water disinfection also using active oxygen makes the water
pure, clear and pleasant when in contact with the skin and hair.
Active oxygen is a delicate alternative to chlorine and may sub-
key stitute it as a disinfectant. It is also eff ective in preventing the
formation of algae.
Jacuzzi off ers a kit for water treatment based on active oxygen,
which along with the aforementioned benefi ts, off ers another
which should not be underrated: when the spa is emptied, the water
can be drained into the sewers without the need for costly purifying
and it can even be used to water the garden.
Active oxygen is especially indicated if the spa is not used in-
tensively.
However, after a long period in which the spa is not used, you
should perform a super-chlorination treatment, also known as a
"shock" treatment, based on chlorine. The use of active oxygen
does not compromise this kind of operation, thus making chlori-
ne necessary only in this case.
A shock treatment can be carried out using active oxygen,
even if this is not as eff ective as chlorine. In this case, the sugge-
sted amount is about three times more than that used for nor-
mal maintenance treatment.
The water treatment kit off ered by Jacuzzi® includes active
oxygen-based tablets and an activation liquid, which increases
the eff ectiveness of the treatment and ensures action against al-
gae. These products are to be placed directly into the water of
the spa, even if it is preferable to place the tablets in the skimmer
basket (see the chapter on cartridge fi lter maintenance) or in the
fl oating dispenser (available from authorized Jacuzzi® dealers).
For doses and methods of use, refer to the instructions on the
package.
