In case of installation with night-time power supply only, in
order to guarantee the boiler protection,
AT LEAST ONCE PER YEAR check regularly the functioning
of the Protection light, forcing the electrical connection in
manual mode ON.

1. Maintenance
Empty the appliance annually ( twice a year if the
water has been treated with a softening agent )
in order to:
1. check the condition of the magnesium anode;
2. remove all deposits inside the boiler.
We strongly recommend that the performance
of the water softener is checked regularly. The
residual hardness cannot be lower than 15ºf.
A water hardness level which is too low will
cause the guarantee to become void.
1.1. Emptying
Cut off the electricity supply before performing
any work on the appliance.
Shut off the cold water supply at the inlet.
Open the hot water tap to draw water.
Open the emptying valve on the safety assembly

1.2. Build-up removal – Checking the anode
Empty the appliance (see above).
Remove the protection element and unscrew
the base (some residual water may leak out).
Clean the boiler: without using metal objects
or chemical agents, remove any build-up on
electrical elements or on the bush (steatite), on
the corresponding casing and on the base of the
boiler.
If a magnesium anode is used, check its
condition: the magnesium anode is consumed
progressively in accordance with the water quality,
in order to prevent corrosion of the boiler. If the
diameter is smaller than 15 mm (for the armoured
range) / 10 mm (for the steatite range), or if the total
volume is lower than 50% of the initial volume, the
anode should be replaced.
Use a new seal every time the base is
replaced after being removed.
When screwing in the bolts again, use a “cross-
tightening” technique. The tightening torque should
be between 18 and 20 Nm.
2.3.2 Products HPC
The boiler protection anode is controlled by an electronic
device powered at the network current, in order to keep
the boiler protected during the night.
In products HPC, the protection is however guaranteed
during the day by the magnesium anode.
ATTENTION: The anti-corrosion system cannot stay wi-
thout power supply more than 1 week.
