In areas where temperatures are only occasionally below 0

°C, the spa can be kept in operation, provided it is equipped with
anti-freeze protection that ensures water is kept at a minimum
temperature

(see the paragraph on maintaining a minimum wa-

ter temperature in the chapter on method of water heating").

MAINTENANCE

GENERAL INSTRUCTIONS

Keep the spa covered at all times when not in use. In this way,

along with keeping the water from getting dirty, you will also
avoid heat loss and evaporation.

CAUTION:

The cover is not designed to withstand weights.

Do not stand, sit or lie on the cover, and do not set

objects on it.

If the spa is installed indoors, the amount of humidity may be

very high, even if the cover is used (when not in use). In these
situations, it is advisable to provide a ventilation system that en-
sures the best level of humidity.

To clean the suction nozzles, remove the cover and its o-ring

(1), using a screwdriver, unscrew the internal filter (2, present on-
ly on the bottom drain), using a cone-shaped spanner (3), thor-
oughly clean the parts and remove any residues.

NOTES

- the intakes must be cleaned with the tub empty. Remember
to refit all the parts before re-filling the spa.
-the suction intake grilles must be checked at least once a
week.

For long periods of disuse, it is advisable to completely drain

the system

(refer to the chapter on emptying the tub and win-

ter shutdown)

. Periodic drainage, during normal use, vary de-

pending on the frequency of use, the contaminants and the type
of installation.
Even if not used particularly frequently, you are advised to re-
place the water at least once a month to ensure water quality.

The baskets of the pre-filters of the compensation tank must

be cleaned at least once a week, or even more often if the spa
is used frequently. The pre-filter located at the inlet of the filtering
pump must also be checked periodically.

CAUTION:

Never clean the filters with the pumps running. Turn

the main switch off first. Always turn the master

switch off when the spa is empty.

FILTER MAINTENANCE

To clean the quartz sand filter, you will periodically need to per-

form backwashing based on the information provided by the
gauge located on the selector valve. This means that you will need
to note the pressure indicated on the gauge during system start-
up, or at the end of a backwash period.

This value varies de-

pending on the type of system and the length of the pipes in
the system, and is normally less than one atm

. When this val-

ue rises to 0.2 atm above the initial value, you must perform
backwashing of the filter.

To perform backwashing, you must stop all the pumps, place the

selector valve in position (

) and then start the filtering pump.

You must also close the valve of the suction line from the

compensation tank (

2, 2a, 3, 3a - detail 31

) and completely

open the valve on the suction line of the spa (

2, 2a, 3, 3a -

detail 31

After a few minutes, or when the drain water is clean

(this can

be seen in the transparent glass on the selector valve)

, refill the

tub and restore initial operating conditions

(filter in position“1”,

ball valves and switches in normal operating conditions)

The sand in the filter needs to be changed when good water

filtering is no longer provided. This is indicated by the need to
increase the frequency of backwashing of the filters. Deteriora-
tion of the sand is mainly attributable to water hardness, but al-
so to certain contaminants that may cause cementing of the fil-
tering material.

NOTE:

Generally, the sand may need to be changed every 3-

4 years, with family use of the spa and water hardness of about
20 °fr.
