In order to avoid problems caused by sudden
pressure changes, we recommend the
installation of a non return valve at the
appliance
In the case of freezing:
▶ Switch off the appliance.
▶ Purge the appliance (chapter 6.3).
-or-

▶ Select the lowest water temperature.
Safety valve
DANGER:
▶ Install a safety valve at the water inlet of
the appliance ( Fig. 9 and 10).
NOTICE:
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 water inlet pressure is between 1.5 and
3 bar, it is not necessary to install a pressure
reducing valve.
If the water inlet pressure is above these
values, it is necessary
▶ to install a pressure reducing valve
(Fig. 9, 10, [4]). The pressure relief
valve will activate whenever the water
pressure in the appliance is above 8 bar
(± 1 bar), for which reason it is
necessary to plan a way of draining off
this water.
▶ install an expansion vessel (Fig. 9, 10,
[7]) to stop the pressure relief valve
opening so frequently. The volume of the
expansion vessel should be equivalent to
5% of the volume of the appliance.
