Maintenance and periodic checks
Titane anode
No maintenance required.
The panel must be switched on to ensure that the anode is
working.
Magnesium anode - Package EA 103 (optional)
The titanium anode can be replaced by a magnesium anode.
The magnesium anodes must be checked at least every 2, years.
After the first check, determine the frequency of future checks on the
basis of anode wear.
The anodes can be checked by two methods:
`
Inspection
the anode must be replaced if its diameter is less than 15 mm
(original diameter = 33 mm).
`
Function test
- disconnect the earth wire from the anode.
- measure the strength of the current between the tank and the
anode. if the current is less than 0.1 mA, the anode must be
replaced.
If the anodes must be replaced, proceed as described below.
Valve or safety unit
The valve or safety unit must be operated at least
once a month
in
order to ensure that it is operating correctly and to be forewarned of
any overpressure which would damage the DHW tank.
Failure to comply with this maintenance rule may cause
deterioration of the DHW tank and the cancellation of the
guarantee.
Descaling
In hard water regions, it is advisable to ask the fitter to descale the
DHW tank exchanger once a year in order to maintain its level of
performance.
Cladding
The cladding of the DHW tank can be cleaned with soapy water.
