Light OFF =
anti-corrosion protection
defect : replace the battery NIMH 9V. If the
defect goes on, contact your installer.
Orange indicator light:
Light ON= under heating
Light OFF = out of heating
If connected to the mains with a dual timer schedule
or exclusive night-time schedule (only for models
with battery), the green indicator light switches on
but is very weak for the first 48 hours in accordance
with the charge status of the battery. Check the
indication light after 48 hours of operation.
In order to guarantee full boiler
protection (green light illuminated),
any faulty batteries must be replaced.
If the batteries are not replaced, the guarantee
will become void. It makes good sense to replace
them once they have been used for one or two
years.
MAINTENANCE AND REPAIRS
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
and the water will flow out of the drainage hole.
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 7 and 10 Nm.
