Fi
tti
ng of the pressure relief and non return valve
The pressure relief and non return valve supplied with
the appliance must be
fi
tt
ed to the cold water inlet (the
arrow on the valve must be poin
ti
ng towards the tank),
without any intercep
ti
on between the valve and the
water heater (1).
This valve has a double func
ti
on:
•
safety func
ti
on:
it allows the discharge of the
water stored inside the tank in case the pressure
exceeds the limit
fi
xed by the valve se
tti
ng.
•
non
return func
ti
on:
it avoids that, because of
the high pressure that may arise inside the tank,
the hot water
fl
ows back along the cold water
tube.
Fi
tti
ng of the drain valve
The
fi
tti
ng of a drain valve (2) is recommended to
empty the tank: it has to be installed between the
safety valve and the appliance.
ATTENTION:
If the appliance is installed in Italy,
the pressure relief valve supplied
with the appliance must be replaced with a safety
group in accordance with the UNI rule EN
1487:2002 (as required by The Memorandum N°
9571 dated 26/03/03 issued by Ministry of Pro
duc
ti
ve Assets
G.U. N° 87 of 14/04/03). In case
of non
installa
ti
on of a safety group in compli
ance with the rule EN 1487, the manufacturer will
be exempted from any warranty claim on the
tank.
2.6 Installa
ti
on o the appliance
Installa
ti
on of a single unit
If just one appliance is installed, it has to be connected
to the water system directly.
Installa
ti
on of several appliances in a row
If several units are to be installed, the appliances have
to be connected as shown in the diagram. Foresee
just one pressure relief and non return valve that
has to be
fi
tt
ed to the cold water inlet of the
fi
rst ap
pliance.
Frame
To give the water heater the right angle, use support
brackets and screws included in the frame. Once you
have determined the right angle of installa
ti
on, you
have to match the hole in the bracket with the hole
in the frame (1): then insert the bolt and
ti
ghten the
nut (2). To give the appliance an angle di
ff
erent from
the ones foreseen by the manufacturer, drill the
frame in order to obtain the desired angle.
2.7 Magnesium Anode
To extend the working life of the appliance, respect
the following parameters, as foreseen by the Euro
pean Direc
ti
ve 98/83/CE (regarding the quality of
water intended for human use):
• overall water hardness:
included between 15
and 50 °F (in par
ti
colar where water has under
gone a so
ft
ening or desalisa
ti
on treatment)
• chloride:s
25 mg/l (max. value 200 mg/l)
• pH:
included between 6,5 and 9,5
• conducibility:
400
μ
S/cm (max. value 2500
μ
S/cm)
