tions that control the drainage of chemically
treated water.
N.B.
if the valve attached to the low-point drain is not easily
accessible, we recommend that you install one near the
drainage point.
In particularly cold areas, to avoid the risk of any remaining water
freezing
(water that may remain in hosing after emptying the sys-
tem)
it is advisable to install valves for the complete drainage of
hosing (
2, detail 31
).
To fill the spa, you can use a garden hose, or provide connections
to the plumbing system of the home as shown in
2, detail 11
.
IMPORTANT: the 3/4” solenoid valve on the compen-
sation tank (for automatic filling of water level) must
always be connected to the water system that sup-
plies the system.
Any connections to the drinking water system (other
than the recommended ones) must be carried out
according to EN1717 regulations, using “AA”, “AB” or
“AD” anti-pollution protection procedures. For fur-
ther information, we recommend you contact your
water supply company and/or your plumber.
Connection of the blower (
2, detail 17
) to the spa must be
made by creating a siphon (
2 and 5, detail B
) as near as pos-
sible to the spa itself. This will prevent situations where the water
might reach the blower and compromise its operation.
If the spa has been ordered without a heater (or heat exchanger) it
is advisable to prepare alternative systems for heating water.
Electrical connections
For preparations/measuring the electric system that will supply
the spa, please note that powers in kW indicated in the “
Maximum
Absorption of the System
” table are to be considered as maxi-
mum absorbed powers during operation.
The installer must use cables with a suitable cross-section (see
table) protected with a sheath of Ø 32 mm at the terminal in que-
stion and/or tubes or pipes when carrying out connection to the
main switch with characteristics not inferior to type H05VV-F
(mul-
tipolar)
or H07 V-K
(unipolar)
.
NOTE: The lead sections must take account not only the
systems absorption but also the cable path and the dis-
tances, the chosen protection systems and the specific
regulations for fixed electrical systems in force in the
country where the spa is installed.
Terminals inside the electric wiring box are suitable for
connecting leads to the following maximum sections:
- model
380-415 V 3N~ 50 Hz:
up to
10 mm
2
- model
220-240 V 3~ 50 Hz:
up to
16 mm
2
Remember that it is compulsory to install a multiple-pole section
switch with characteristics that are no less than the ones given in
the “Electrical Safety” chapter and
3
, taking into account the
maximum absorption of the system.
The installer must comply with the above regulations,
and also use
watertight connectors at connection points. He must also
guarantee compliance with the specific current standards for
systems in the country in which the spa is installed.
Compliance with this regulation is obligatory: any other proce-
dure is prohibited.
Spa-Pak and compensation tank
The Spa-Pak must be installed in a ventilated indoor area, which
is only accessible to those with a key or tools, and it must be pro-
tected from water and bad weather.
N.B.
Since certain settings and general maintenance operations
require access to devices present on the Spa-Pak (heating tem-
perature setting, filter backwash, emptying the system, etc.), it is
advisable to ensure easy access to the systems control.
The compensation tank (to be installed as close as possible to the
Minipool and the lowered platform,
2
) must be closed so that
the electrical devices on it are not accessible to the user without
a key or tools.
Ways of limiting access (for both the Spa-Pak and the compen-
sation tank) to unauthorized persons must take into account elec-
trical protection (direct and indirect contact) and the characteris-
tics of the materials used; in particular, any filler panels or struc-
tural parts, if made of conductive material, must guarantee con-
nection to the protection circuit (earth) and any supplementary
equipotential connection, if required by the type of installation.
When plastic materials, wood, etc. are used, make sure that they
are approved for use with electrical installations, and approved for
self-extinguishing properties.
Preparations for installation
Prolonged sun exposure could damage the material of whi-
ch is made the spa shell, due to its capacity to absorb heat
(dark colours in particular). Don't leave the spa to sun ex-
posure without adequate protection when not in use (cover
thermal, gazebo, etc.).
Any damage arising by not following these warnings are
not covered by the guarantee.
For indoor installation, it is necessary to remember
that water evaporation from the spa (especially where
high temperatures are involved) can cause very high lev-
els of humidity. Natural or forced ventilation helps to
maintain personal comfort and reduce damage to the
