16 HYDRAULIC CONNECTIONS
The appliance will last longer if they are met, as provided by D. LGS. February 2, 2001, 31 (implementation of
Directive 98/83 / EC on the quality of water intended for human consumption), the following parameters:
1. Total hardness: between 10 ° F and 25 ° F.
2. PH: comprised between 6 and 8
3. Chloride: max 200 mg / l
4. Conductivity: max. 2500 mS / cm
In the presence of water with different parameters to the above, it should be given special care in the periodic
maintenance of the tank. In particular it must be replaced several times a year the magnesium anode.

SAFETY VALVE: l
'Appliance is equipped with a safety valve against excess pressure.
The component of the function is to download the tank water in the presence of an internal pressure higher than the
maximum pressure of the tank (for example during the water heating).
the possible from the valve discharge of dripping water means the presence of an overpressure and the correct
intervention of the valve. If this happens you must turn off the power and remove the cause of the overpressure
the removal or tampering of the safety valve constitutes danger to the user (in addition to cause the non-
recognition of the guarantee for damage from overpressure).
The setting of the valve pressure is stamped on the cap of the same and is expressed in Bar. The fluid discharged
during the possible intervention for overpressure must be conveyed downwards (consider that in the exhaust pipe
downstream decreases the exhaust flow rate.
If drips are caused by impurities deposited on the valve membrane it is possible to remove them by turning the knob
and raising the membrane.
