Cleaning the heating system

At the fi rst installation, it is necessary to pre-clean the installa-
tion.
In order to ensure the proper functioning of the appliance,
after each cleaning operation or water substitution, verify that
the appearance of the liquid system is clear, without visible
impurities and that water hardness is under 20°F.

Characteristics of the water supplied to the appliance

Ensure that the system is supplied with water having a maxi-
mum hardness of 20 ° F.
For areas where the water is particularly hard, provide a water
softener does not change in any way the warranty, if the com-
ponent is installed in a proper manner and is subject to regular
checks and maintenance.
In particular, the hardness of the water supplied to the ap-
pliance, must never be less than 12 ° F.
In case of aggressive water ﬁ lling (the pH should be kept
between 6.6 and 8.5), ferruginous or hard, use treated water
in order to prevent scaling, corrosion and damages to the ap-
pliance. Please note that even a small amount of impurities in
the water may decrease the performance of the installation.
The used ﬁ lling water must absolutely be treated in case of
installation of large capacity (high volumes of water) or in case
of frequent replenishments of water in order to maintain a
constant level of liquid in the installation. Where it is necessary
to proceed with the cleaning of the installation, ﬁ ll the entire
system with treated water.

Verify that the maximum pressure, at the level of the water
supply, does not exceed 5 bar. Otherwise, provide the instal-
lation with a pressure reducer valve.
