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 diffe-
rent wire bundles.
● Drain the tank and disassemble the hea-
ting assembly.
● Remove any deposits in the form of slud-
ge or scale on the bottom of the tank and
clean the ducts of the heating elements and
the thermostat. Do not scrape or tap scale
stuck to the walls, since this could damage
the coating.
● The anode is made of titanium and no
inspection or replacement is necessary.
● Reassemble the heating assembly using a
new seal, and tighten the nuts moderately
and gradually (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 neces-
sary for descaling or if the heater must
remain out of operation 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
electricity power supply off and inform your
installer.
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 tempe-
rature 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.
User recommendations
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.
