▶ Use the appropriate connection accessories to do the
hydraulic connection to the appliance.
 Galvanic insulator
 Hot water outlet
 Safety valve
 Drain connection
 Cut off valve
 Reduction valve
 Non return valve
 Connection to the water line
In order to avoid problems caused by sudden
pressure changes, we recommend the
installation of a non return valve at the
appliance (Fig. 10, ).
In the case of freezing:
▶ Switch off the appliance.
▶ Purge the appliance (chapter 6.3).
▶ Install a safety valve at the water inlet of
the appliance (Fig. 10).
NEVER OBSTRUCT THE PURGE OUTLET OF
THE SAFETY VALVE.
Never install any accessory between the
safety valve and the cold-water inlet (right
hands side) of the appliance.

If the pressure at the cold water inlet is
superior to that of 80% of the maximum
pressure of the appliance at, ie: 6,4 bar:
▶ Install a reducing valve (Fig. 10).
The safety valve will trigger every time the
water pressure in the appliance exceeds 8
bar ( 0,5 bar). A facility for draining the
expelled water must be provided.
By electrical discharge!
▶ Before working on the electrical
components, firstly cut the power, (fuse,
circuit breaker or other).
All adjusting devices, verification and safety mechanisms were
submitted to a rigorous test in factory and are ready to work.
▶ The appliance should dispose of an
independent connection to the DB board
(electric board), protected by a 30 mA
differential circuit breaker and earthing.
The electrical connection must be realized in
accordance with the current country laws
regarding electrical installations.
▶ Connect the appliance via a socket with earth connection.
▶ Verify that the appliance has been correctly installed and
▶ Open the water inlet valves.
▶ Open all the hot water taps in order to ensure all the air is
purged from the piping.
▶ Control the tightness of all the connections and ensure that
the appliance fills to its full capacity.
▶ Connect the appliance to the electric current.
▶ Inform the customer of any user information of the
appliance and handling.
