1.2 Recommendations

Note
● The appliance is intended to be permanently connected
to the water mains.
● Maximum / minimum water inlet pressure: See chapter
on Technical Specifications.
● The pressure limiter device must be regularly operated
in order to remove limescale deposits and ensure that it
is not blocked.
● Draining: Shut off the domestic cold water inlet. Open a
hot water tap in the installation and then open the valve
on the safety unit. When the water stops flowing, the
appliance has been drained.
● A pressure reducer (not provided) is necessary when
the supply pressure exceeds 80% of the calibration of
the safety valve or safety unit and it must be located
upstream of the appliance.
● As water may flow out of the discharge pipe on the
pressure limiter device,
the discharge pipe must be kept open to the air.
● Connect the pressure limiter device to a drainage pipe,
kept open to the air, in a frost-free environment, and at a
continuous downward gradient.
Caution
Install the domestic hot water tank in a frost-free
environment.
Caution
If the home is unoccupied for a long period and there is a risk
of frost, drain the domestic hot water tank.
