WATER CONNECTION
The appliance will last longer if the following parameters are met (as provided by the D. LGS. nr 31 February 2
nd
2001, which is
an implementation of EC Directive 98/83/CE on the quality of water intended for human consumption):
1.
Total hardness:
between 10 ° F and 25 ° F
2.
pH:
between 6 and 8
3.
Conductivity:
max. 2500 µS / cm
The appliance is protected against corrosion by a magnesium anode that must be replaced at least once every 12 months
otherwise the warranty will be invalidated.
IMPORTANT: IF THE QUALITY OF WATER IS NOT WITHIN THE ABOVE PARAMETERS, PARTICULAR CARE SHOULD BE TAKEN IN THE
PERIODIC MAINTENANCE OF THE TANK. THE REPLACEMENT OF THE MAGNESIUM ANODE MORE THAN ONCE A YEAR WILL BE
COMPULSORY.
HYDRAULIC COMPONENTS TO BE INSTALLED (NOT INCLUDED)
A.
T drain tap
B.
Expansion vessel, the capacity of which has not to be less than 5% of the capacity of the appliance.
C.
Softener, in case of particularly hard water (compulsory above 25 ° F).
D.
Pressure reducer (in case of
water inlet pressure ≥ 6 kPa).
E.
Filter to remove water impurities.
F.
Check valve
G.
Shut-off valve
H.
Shut-off valve
CONDENSATE DRAIN
Apply a flexible hose to the outlet of the siphon condensate discharge, in order to channel the condensate liquid.
SAFETY VALVE
It discharges the water from the tank in case the internal pressure of the tank exceeds 6.5 ± 0.5 bar. The valve is factory sealed
and its tampering is forbidden, otherwise the warranty on the appliance will be invalidated. In the event the valve discharges
water, it will be necessary to reduce the inlet pressure of water into the appliance.
