Check the operation of the hydromassage pumps using the
"Pump" key. The first time the key is pressed the pump
starts at low speed; the second time it is pressed, high speed;
the third time, the pump turns off.
Check that the spotlights switch on and off using the "Light"
key.
Check that there are no leaks from the hydraulic connec-
tions or other problems.
Completely disinfect the MaxiJacuzzi by carrying out "su-
per-chlorination" treatment (also called shock treatment,
see the chapter on "Water Treatment").
This operation is recommended when installing, or after a
long period of not using the MaxiJacuzzi
After a few hours, turn off the all pole circuit breaker (mains
disconnect switch, see the pre-installation sheet).
Open the drain valve and completely empty the bath.
CAUTION
Do not use the MaxiJacuzzi

Immediately empty the bath.
Close the drain valve and re-fill the MaxiJacuzzi

Set the water heating temperature. Keep in mind that the
time required to reach the desired value depends on the ini-

As a rule of thumb, an electric heater of approximately 2 kW
increases the temperature of 1 m

WATER TREATMENT
The water must be "inviting", that is, clear, limpid and free from
those substances that, accumulating, can create a suitable
environment for the growth and spread of bacteria; for this
reason, as well as being filtered 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 specialised companies, who will unques-
tionably be able to provide the best solution.
Disinfectants for spas and pools
Certain disinfectants used in large swimming pools, such
as chlorine, calcium hypochlorite and sodium hypochlo-
rite, are not suitable for spas.
Chlorine tablets permanently stain the methacrylate (after
prolonged direct contact), calcium hypochlorite (normally
available in granules) encourages calcium deposits and sodi-
um 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 partic-
ularly suitable if the MaxiJacuzzi 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 advan-
tage over chlorine, in that it is less of an irritant, has less in-
fluence on the pH level and has no smell. Furthermore, un-
with fresh
like chlorine, bromine does not separate into "combined"
and "free" forms.
Water disinfection also using active oxygen makes the wa-
ter pure, clear and pleasant when in contact with the skin and
hair. Active oxygen is a delicate alternative to chlorine and
may substitute it as a disinfectant. It is also effective in pre-
venting the formation of algae.

gen, which along with the aforementioned benefits, offers an-
other 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-
® and tensively. At any rate, after a long period during which the spa
is not used, it is advisable to carry out a super-chlorination treat-
ment, also known as a chlorine based shock treatment. The use
of active oxygen does not compromise this operation, thus mak-
ing use of chlorine necessary only in this case.
A shock treatment can be carried out using active oxygen,
even if this is not as effective as chlorine. In this case, the sug-
