To make the performances of your heater last for many years it is necessary to have the equipment inspected
every two years by a specialist, who shall proceed as follows :

Maintenance by a specialist

● Switch off the electricity power supply to the
heater (protection) and disconnect the wires to
the thermostat terminals.
● Remove the thermostat and its plastic base
after having disconnected the different wire
bundles.
● Drain the tank and disassemble the heating
assembly.
● Remove any deposits in the form of sludge or
scale on the bottom of the tank and clean the
ducts of the heating elements and the thermo-
stat. Do not scrape or tap scale stuck to the
walls, since this could damage the coating.
● The anode is made of titanium and no inspec-
tion or replacement is necessary.
● Reassemble the heating assembly using a new
seal, and tighten the nuts moderately and gra-
dually (crosswise).
● Fill the water heater leaving a hot water tap
open; when water comes out of this tap, the
water heater is full.
● Check waterproofness at the seal and then
and only then put back the thermostat and its
base and reconnect the electricity power supply.
● Check again the next day to make sure that
the seal is not leaking, and retighten the nuts
again slightly if necessary.
● Check the condition of accessories and wires.
● Clean the sheath inside to remove scale.
● In regions in which the water is very hard Th
> 20°F, the use of a softener does not make our
guarantee null and void provided that it is set in
accordance with standard practice, and that it is
regularly checked and maintained.
● Proceed as follows when you want to drain
your water heater (operation necessary for des-
caling or if the heater must remain out of ope-
ration in a room in which frost is possible):
a) switch the electricity power supply off
b) close the cold water inlet
c) open a hot water tap
d) open the safety valve drain tap
● If there is a problem ,no heating or steam
escapes when the valve is open, switch the elec-
tricity power supply off and inform your instal-
ler.
Note that the water storage temperature used
to be 80°C before.
For safety reasons it is now only 65°C +/- 5 in
the tank. Consequently, the amount of hot water
available with a heater of the same capacity may
be smaller.
To reduce the risk of scalding:
- In toilet facilities, the maximum temperature of
the hot water is restricted to 50°C at the outlet
points;
- In other facilities, the temperature of the hot
water is restricted to 60°C at the outlet points.

A water heater requires little maintenance for
the user : operating the safety valve regularly
(refer to the manufacturer's instructions).
Check periodically if the pilot light is on. If not,
contact your local installer.
