User information
Inform the user on how to operate the installed system.
In particular, hand this instruction manual to the users, inform-
ing them that is must be kept near the product at all times.
Inform potential users that the following actions must be car-
ried out:
– Periodically check the system water pressure.
– Restore system pressure, by deaerating the system
when necessary.
– Adjust the setting parameters and the adjustment de-
vices to optimise operation and reduce the system’s
operating costs.
– Perform regular maintenance, as envisaged in the
standards.
4.12.1 Filling the system
Check the water pressure on the pressure gauge regularly and
make sure that the pressure is between 0.5 and 1.5 bar when
the system is cold.
If the pressure is below the minimum value, it must be in-
creased through the filling cock.
Close the cock once the average value of 1.2 bar has been
reached.
The maximum pressure of the heating/cooling system is 3 bar.
Only for NIMBUS HYBRID MODULE NET R32
For filling operations, open valve (A) and follow the instruc-
tions contained in the boiler manual.

The installation, initial start up, and configura-
tion must be carried out in accordance with the
instructions, by a qualified technician only. The
manufacturer declines all responsibility for dam-
ages caused to people, animals or possessions
following incorrect installation of the appliance.
a
If frequent fillings (once a month or more fre-
quently) are required for your system, this indi-
cates a potential problem with the installation
(leaks, expansion vessel problems). Contact your
trusted installer to analyse and solve the prob-
lem quickly, and to prevent damage caused by
corrosion of the components due to excessive
water replacement in the system.
