GB
WARNING!
Install the appliance to a solid wall, not
subject to vibrations.
When drilling the wall, take care not to
damage any existing electrical wiring or
pipes.
Make sure the installation site and any
systems to which the appliance must
be connected comply with applicable
regulations.
POSITIONING
To allow easy access for maintenance,
make sure to install the unit with suffi -
cient clearance around it.
Position the appliance near the chosen
wall so that the two inlet and outlet pipes
are parallel to it.
Should the water heater be installed in
the corner between two walls, keep suf-
fi cient distance between the wall and the
appliance for the installation and disman-
tling of the components.
Place of installation
The choice of installation location must
observe applicable regulations.
The appliance must be installed perfect-
ly vertical. The appliance may not be in-
stalled in the vicinity of a source of heat.
Do not install the appliance in a place
where the temperature may fall below
0°C.

WATER CONNECTION

• Connect the heater to the water distri-
bution system using a 3/4" pipe. The
cold water inlet is on the right (blue
ring) while the hot water outlet is at the
left (red ring) as seen from in front of
the heater.
• The heater must be fi tted with a water
safety valve - non-return valve (sup-
plied with the heater) fi tted to the inlet
50
pipe (blue ring). You must not tamper
with the valve for any reason.
• Make sure by running the water for
some time, that there is no foreign ma-
terial in the water supply line, such as
swarf, sand, pipe dope etc.
Should any such material enter the
water safety valve - non return valve,
there can be faulty valve operation
and in some case faults to the valve
itself.
• Make sure that the water supply pres-
sure is lower than 7 bar (0.7 MPa). If the
pressure is higher, you must fi t a high
quality pressure reducer valve. In this
case the safety valve will necessari-
ly drip during heating. Said drippage
must appear even if upstream of the
valve there is a non-return valve.
• Avoid the dripping of the valve falls on
to the water heater.
Apply the valve, envisioning a small
collection funnel (drip) connected to
the drain.
IMPORTANT!
If the appliance is installed in a hard
water area (> 200 mg/l), a softener
should be installed to limit the amount
of limescale building up in the heat ex-
changer.
The guarantee does not cover damage
caused by limescale.
