The water inlet and outlet are marked:
the inlet is for cold water (blue) and the
outlet is for hot water (red).
It is advisable to install the appliance
close to a hot water intake to avoid heat
loss due to the overly long pipes and
close to wastewater pipes to help with
emptying the tank.

The dielectric unions must be used for
the warranty to apply. Without them, the
useful life of the tank is reduced and the
appliance is not covered by the warranty
as this is considered poor installation.

installed.
The
pressure range of the safety value must
be 0.75 Mpa (7.5 bar). When installing,
a wastewater pipe must be inserted in
the valve hole which may drip in case
of excess pressure and thus vacate the
pressure inside the tank. Make sure that
the pipes are not obstructed to avoid
excess pressure.
– Install the safety valve on the cold
water inlet, marked by a blue ring, in
the lower part of the water heater.
– The valve must be operated regularly
to avoid the accumulation of limescale
which may cause it to become blocked.
– The water heater is drained by means
of the lever on the safety valve.
WORKING
POSITION
– The water will trickle from the
wastewater pipe of the safety valve so
it must remain open to the atmosphere
or must be installed with a continuous
slope avoiding bends and free from
any freezing temperatures.
– Connect the hose to the safety valve.
Make sure that the pressure of the
water supplied does not exceed 3
bar. If the pressure is greater, there
is a risk that the valve will leak water
when the water heater is working so
a pressure-reducing valve will need to
be installed (fig.5).
– Connect the other hose to the hot
water outlet, marked by a red ring.
