adapter in cast iron or stainless steel, avoid components in brass or copper
or any other material with high conductivity power). Avoid the connection to
be more than 100mm.
• Tighten the heater with a suitable wrench, applying a tightening torque no
greater than 10kg for the tightening , do not apply torsion to the external
case of the heater.

4. Operating conditions
Comply with all regulations about the maximum hot water storage
temperature.
The heater must be used within the above stated temperature limits (for
no reason with a temperature higher than 100°C) and exclusively to warm
drinkable water, deprived of any impurity or polluting substances and with
hardness included within 7 and 20°Fr.
WARNING:
In case of water with hardness value >20°F (where 1°F=French
degree=10mg CaCo3/l), to preserve heating element efficiency, it is
necessary to install a suitable system (softener or conditioning agent
dispenser) to reduce the formation of lime scale inside boiler and/
or proceed with a periodic cleaning of the heating element, avoiding
carefully any damage. Damages and malfunctions arising from lime
scale deposits will void product warranty.
In case of impurity, it is required to provide filters at the source of the
accumulation circuit.
Make sure that environment of installation respect the following requirements:
1.
ambient temperature included between 5°C and 45 °C and
humidity ≤ 0.015 kg of water per kg of dry air ( see chart)
2. heater placed far from heat sources and in areas with good
ventilation.
