1.1.8. HYDRAULIC CONNECTION
DANGER
Make sure that the tubes of the water
and heating plant are not used as grounding
system for the electrical plant. There are not
suitable for such use.
WARNING
To prevent voiding the warranty and to
ensure the proper operation of the boiler, please
wash the plant (if possible when hot) with suitable
pickling or descaling solutions in order to remove
the impurities coming from tubes and radiators.
WARNING
When connecting the equipment
to water supply, avoid excessive bending and
recovery operations from any off axis positioning
that may damage the tubes causing leaks,
malfunction or early wear.
WARNING
In order to avoid any vibrations and
noises, do not use tubes with small diameters or
elbows with small radius and significant cut-off
of the passage sections.
WARNING
Connect the outlets of safety valves,
three-ways valves (if present) and of the cylinder
(if present) to an outlet funnel, to prevent the
boiler room from flooding if these devices cut
in. This outlet should preferably be sent to the
outside so as to avoid damage to persons or
property caused by hot water in the event that
the valve should open. The manufacturer is not
responsible for any flooding due to the opening of
the safety valve in case of system overpressure.
WARNING
On systems with a closed expansion
tank, the pressure reducer on the automatic
supply unit (where available) should be set to a
pressure that will not exceed the initial design
setting. Make sure that while the equipment is
working the system pressure does not exceed the
working pressure for each component.
WARNING
Ensure that, during the boiler
operation, the system pressure doesn’t exceed
the working pressure of each component.
WARNING
In order to prevent scales or deposits
on the primary heat exchanger, the heating/D.H.W
circuit inlet water must be treated according to
the current regulations.
It is however suggested to treat the water:
› for the heating circuit, over 25 French degrees,
by means of chemical conditioning treatment
for powers < 100 kW or sweetening for powers
> 100 kW.
› for the D.H.W, over 15 French degrees, by means
of chemical conditioning treatment for powers
< 100 kW or sweetening for powers > 100 kW.
It is also necessary to install a safety filter to
protect the system.
WARNING
In case the boiler is installed as part of
a low temperature circuit, please install a safety
thermostat on the heating flow, which can stop
the boiler activity in case of high heating flow
temperature. The company
assumes
no
liability for damage caused to persons or for failure
to comply with these instructions.
