If installation is made indoors, it is advisable to provide a
drain system under the support area of the hot tub which is
connected to the main drain, connecting the main drain also
to the fitting present on the base (
Considering the large amount of water in the hot tub, this
precaution is advisable should there be accidental water
leakage (also see
If installation is made outdoors it is possible to make
drainage holes, on the base using a drill, to drain possible
accumulation of water due to condensation.
To periodically empty the hot tub you can:
- connect a pipe to the drain valve, after removing the plug and
screwing in the fitting with gasket (included,
NOTE: To open the valve, you must turn the ring nut anticlockwise
and pull it, therefore if you decide to connect the hot tub perma-
nently to the ground drainage point, we recommend you install a
valve below, bypassing the valve installed in the factory.
- connect a tube to the T-fitting, first removing the plug (
det. B1). In this case, it is obligatory to install a gate valve down
the line. This connection is useful for reducing emptying time.
- as an alternative, bypass the valve B installed at the factory and
connect the tube to the drain B1 (
NOTE: drain B1 lets you partially empty the tub. The lower part is
emptied by means of the tube connected to valve B.
It is possible to connect the drain and the overflow together,
however after the gate valve (installed on the discharge tube)
since the overflow must always be open.
You can use a garden hose to fill the hot tub.
If the hot tub is connected, for periodic filling, to the
mains system that supplies drinking water, this con-
nection must be carried out in compliance with the
EN1717 norm, using "AA", "AB" or "AD" anti-pollution
protection procedures. For further information, we
recommend you contact your water supply company
and/or your plumber.
The Unique hot tub can be installed in various ways:
- free standing on the floor or on a specifically prepared base
( 5).
- Semi-built in, so that only the base of the hot tub is built-in
and therefore the side cover panels remain free (
case, it is appropriate to prepare some removable under-frames
(in marine plywood, etc.) that, besides aesthetically completing
installation, allow the panels to be removed more easily. The size
of the built-in space in the floor is obtained from that of the base
of the hot tub ( 1).
- built-in, with the tub edge (

tom of the tub (in concrete and steel beams, (detail 1).
Access to the plumbing must be ensured and to all other elec-
tromechanical parts that are under the tub, for example by mak-
ing a passage along the outer perimeter, that is wide enough
(about 80 cm) to carry out all electrical and hydraulic connec-
tions and any maintenance operations (detail 2). This passage
can be closed using removable under-frames (detail 3), with suit-
able supports (detail 4).
Drainage for any water stagnation must also be provided (de-
tail 5).
Prolonged sun exposure could damage the material
of which is made the hot tub shell, due to its capacity
to absorb heat (dark colours in particular). Don't leave
the hot tub to sun exposure without adequate pro-
tection when not in use (cover thermal, gazebo, etc.).
Any damage arising by not following these warnings
are not covered by the guarantee.
In any case, you will need to provide a support base that is suit-
3, able for the load of the hot tub as shown in the table of weights
above.
If the hot tub is installed indoors, remember that water evapo-
ration from the hot tub can cause very high levels of humidity,
especially if temperatures are very high. Natural or forced venti-
lation helps to maintain personal comfort and reduce damage to
the building due to humidity.
Jacuzzi Europe refuses all responsibility for any damage caused by
excessive humidity or by overflowing water. Consult a specialist for
indoor installation.
Concerning suitability of the electrical system and of connec-
tions, refer to the installation manual (see the chapter on electri-
cal safety).
Electrical preparations
The electrical connection can be made as follows:
- single-phase line (220-240V 1~)
- three-phase line consisting of two phase conductors + neu-
tral conductor (380-415V 2N~)
The rated power supply voltage of the equipment is al-
ways 220-240V.
The equipment can also be installed in Countries where
the 220-240V voltage is supplied by a two-phase system. For
6). In this the connection please refer to the instruction manual.
The installer must in any case use properly protected cables
with a suitable cross-section (220-240 V~: min. 4 mm
V~: min. 2,5 mm
VV-F.
Note: The cross-sections of the wires must take account not
only the systems absorption but also the cable path and the
distances, the chosen protection systems and the specific
