3.6 Water connections
3.6.1 General warnings
The water connections must be carried out by professionally qualified personnel in accordance with
relevant standards.
It is recommended that the system is hot-flushed to remove any impurities (especially oil and grease)
that might compromise the proper working operation of the heating unit, from the pipes and radiators.
Make sure that the central heating pipes are not used to earth the electrical system. The pipes are
totally unsuitable for this purpose.
The unit should be filled slowly to allow the air to escape through the manual valve fitted as standard
on the unit; check in addition that all the air has been completely purged from the other parts of the
circuit and that the pressure when cold is about 1.2 ÷ 1.5 bar or in any case the pressure set by the
heating engineer.
Connect the outlets of the safety valves 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.
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.
It is always advisable to fit the unit in an accessible position to facilitate periodic cleaning operations.
To prevent vibration and noise coming from the system, do not use pipes of reduced diameter, short radius
elbows or severe reductions in the cross sections of the water passages.
