Electrical Safety; Electrical Preparations - Jacuzzi flow Vorinstallationsblatt

In any case, you will need to provide a support base that is suit-
able for the load of the spa as shown in the table of weights above.
If the spa is installed indoors, remember that water evapora-
tion from the spa can cause very high levels of humidity, espe-
cially if temperatures are very high. Natural or forced ventilation
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.
See the chapter on "Electrical safety" with regards suitability of
the electrical system and of the connections.

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
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 2 ), with characteristics not inferior to type H 05
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
regulations for fixed electrical systems in force in the coun-
try where the spa is installed.
The junction box terminal board is designed for cables with
sections up to 6 mm 2 .
To ensure the degree of protection against splashes of water
as required by standards, and to make connection to the elec-
trical mains easier, the electronic box is equipped with a cable
clamp M25 x1.5 mm.
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 stand-
ards for systems in the country in which the spa is installed.
It is mandatory to comply with this instruction. Any other
procedure is prohibited.
Timer or timer switch set-up
("silence" function)
Flow is equipped with a function which enables the suspension
of circulation pump activity to avoid noise during unsocial hours.
This function (named "Silence") is activated when a signal is sent by
the timer or timer switch to the tub electrical box.
Where this function is used, it is necessary to employ a timer
equipped with a normally open contact, to be connected to the
electrical box using a 2 x 0.75 mm2 cable, type H-05 VV-F.
Refer to the installation manual for the wiring diagram.

Electrical safety

The Jacuzzi® spas are safe products, manufactured in compli-
ance with standards EN 60335.2.60, EN 61000, EN 55014 and
tested during production to ensure user safety.
Installation must be carried out by qualified and authorized
personnel, in compliance with current national provisions.
It is the responsibility of the installer to select mate-
rials based on their intended use, to carry out work
properly, to check the condition of the system that
the unit will be connected to and that it ensures safe-
ty of use also concerning maintenance work and the
possibility to examine the system.
The Jacuzzi® spas are class "1" appliances and therefore they
must be permanently connected, without any intermediate
connections, to the electrical system and to the protection sys-
2
; 380/415 tem (earth system).
The electrical system of the building must be pro-
vided with a 0.03A differential switch and with an ef-
ficient protection (earth) circuit.
Check for proper operation of the differential switch
by pressing the TEST button, which should trip.
Parts incorporating electrical components, except for
remote control devices, must be located or fixed so
that they cannot fall into the bath.
Parts containing live parts must be inaccessible to a
person in the bath.
For electrical connections, the installation of a multiple-pole
section switch is compulsory. It must be positioned in a place
that complies with safety regulations and, in any case, which
cannot be reached by those using the spa.
It is mandatory to comply with this instruction. Any other
procedure is prohibited.
If the building's electrical system is not able to guaran-
tee a stabile power supply, it is recommended to install
a voltage stabiliser that suitably dimensioned for the
required power upstream of the equipment.
