Position the spa away from glass and/or reective sur-
faces in order to avoid possible damage to its panel-
ling.
 The customer must make provisions for a ground drainage 
point (
 9) of suitable dimensions and that can be inspected 
for any cleaning that may be required.
  
ATTENTION: Before preparing the drainage system 
to connect the spa to, consult the local authorities 
about the regulations for disposing of chemically 
treated water.
 Jacuzzi® spas are equipped with a drain as in  1-8, part.A-C 
and  9.
 For periodic emptying of the spa  you can connect a rubber 
hose to the drain valve  ( 1-8, part.A-C and  9).
NOTE: To open the valve, turn the ring nut counter-clockwise and 
pull. 
If you decide to attach the spa to the drain, it is advisable to connect 
upstream from the valve (for greater ow capacity) and to install a 
shutter valve near the drain in an accessible area.
  According to the type of installation chosen the ground drain-
age point will then be put into position. The Jacuzzi® spas can be 
installed in a variety of ways:
- Free standing on the oor or on a specically prepared base 
( 10).
 
- Semi-built in, so that only the base of the spa is built-in and 
therefore the side cover panels remain free ( 11). In this case, 
it is appropriate to prepare some removable under-frames (in 
marine plywood, etc.) that, besides aesthetically completing in-
stallation, allow the panels to be removed more easily.
 In any case you will need to provide a support base that is suit-
able for the selected model, taking into consideration the data 
contained in the table “Weights”.
 
 In the case of intermediate ooring, terraces, roofs or 
other similar structures, consult a building engineer.
 
 ( 12) The support base must be at and level in or-
der to provide uniform support for the weight of the 
spa. Otherwise the front panels and/or methacrylate 
shell could be damaged: this damage is not covered 
by the warranty.
  
   Prolonged sun exposure  could damage the material 
of which is made the spa shell, due to  its capacity to 
absorb heat (dark colours in particular). Don’t leave 
the spa to sun exposure  without adequate protec-
tion when not in use (cover thermal, gazebo, etc.).  
Any damage arising by not following these warnings 
are not covered by the guarantee.
  
 The evaporation of water in the spa may lead to very 
high levels of humidity, particularly when the ambi-
ent temperature is high. Natural or forced ventila-
tion will help preserve the users’ comfort and reduce 
damage caused to the building by humidity. 
    
Make sure any paving, furnishings, walls, etc. pres-
ent in areas adjacent to the spa are suitable for use 
in the conditions mentioned above. 
Jacuzzi Europe refuses all responsibility for any damage caused by 
excessive humidity or by overowing water. Consult a specialist for 
indoor installation.
Q (
  12a)  If you want to install the spa against multiple 
walls, a space must be guaranteed for the removal of the 
panels and for any maintenance, and access must be guaran-
teed to the equipment in the tub compartment.
 You can use a garden hose to ll the spa.
 
 If the spa is connected, for periodic lling, 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.
       
ATTENTION: (IEC 60335-1) The pressure of the hy-
draulic system that supplies the equipment must 
not exceed 600 kPa (6 bar) and, in case water is sup-
plied through solenoid valve(s) (eg. balance tank) 
the pressure must have a minimum value of 35 kPa 
(0.35 bar).
Electrical preparations
QThe electrical connection can be made in the following ways 
( 13):
All models
-  single-phase line (220-240V 1~) for providing power to the 
pump(s) and heater (L1+N1).
-  two separate single-phase lines for providing power to the 
pumps and heater:
  L1+N1/L2+N2 
  J-415: 12A/10A (5.1 kW)
  J-425, J-435, J-445, J-465, J-470, J-480: 12A/17A (6.7 kW)
  J-495: 12A/24A (8.3 kW)
only models J-425/435/445/465/470/480/495
-  three-phase line (380-415V 3N~) consisting of three phase-con-
ductors + a neutral conductor for providing power to the 
pumps and heater:
  L1+N1/L2/L3
  J-425, J-435, J-445, J-465, J-470, J-480: 12A/10A/7A (6.7 kW)
  J-495: 12A/10A/14A (8.3 kW)
