MAINTENANCE AND PERIODIC CHECKS
•
Safety valve or group
•
Magnesium anode
The magnesium anode must be checked at least every two years.
Starting with the first check and taking account of the wear to the
anode, the frequency of the following checks must be decided. The
anode can be checked according to one of the following two
methods:
-
Visual check:
The anode must be replaced if its diameter is less than 15mm
(initial diameter = 33mm)
-
Check by measurement:
- Disconnect the earth wire to the anode.
- Measure the current between the tank and the anode; if
the current is less than 0.1 mA, the anode must be
replaced.
•
The outside of the unit can be cleaned with soapy water.
•
Replace the inspection cover taking care to place the salt
rod at the bottom and refit the washer:
- position the lip seal in the inspection hole, being careful
to place its tongue outside the tank.
- position the retaining ring around the seal, placing the
tongue above the ring.
- Refit the cover, salt rod at the bottom, on the flange,
tightening the 6 bolts evenly across the diameter of the
cover.

WARNING
IMPORTANT
:
The safety unit must be used
periodically (at least once per month).
To do
this, place the safety group in the draining position.
This allows the evacuation of any deposits which
could eventually obstruct the safety group valve.
Non-compliance with this requirement could
result in a deterioration of the unit's tank
(see
notice enclosed with the safety unit).
•
De-scaling:
in hard water regions, it is advisable to ask the installer to
carry out an annual de-scaling of the tank exchanger so that
it will retain its performance.
Operations to be carried out during the de-scaling, visual checks
and replacement of the magnesium anode.
•
Shut off the cold water supply and drain the tank. To drain it
via the safety unit, put the latter into the drainage position
and open a hot water tap so that air can enter.
•
Take off the front panel and the probes.
•
Take off the cover (13 mm spanner).
•
If necessary, replace the anode.
•
Remove all the scaling deposits from the bottom of the tank.
The exchanger must be de-scaled in order to guarantee its
proper operation.
