VI - MAINTENANCE
An annual inspection of the tank is compulsory. It
must be carried out by a qualified professional.
All spare parts will be original parts and must be
ordered using the references in chapter VII -
PARTS LIST - page 26, specifying the appliance
type and serial number.
Disconnect the electricity supply before
carrying out any action on the tank.
1 - TANK MAINTENANCE
- In very hard water regions

(TH > 30) if the tank needs to be cleaned
frequently, the ideal solution is to add a water
softener to the installation or to install an anti-
limescale treatment system on the installation's
cold water inlet.
Adjust the domestic hot water temperature to
a value of less than 60°C. Limescale spreads
quicker above 60°C.
- If the tank is inspected through the access flap (8,
fig. 13) provided for the purpose:
• remove the protective plate (22) - remove the
3 screws (23),
• remove the insulation ( 18),
• remove the access flap (8), flap flange (19) and
seal (20),
• replace the flap (20) each time it is removed,
• refit the assembly,
• after filling:
. check that the tank is watertight,
. drain the tank thoroughly.
2 - DRAINING
The hot water tank may be drained by siphoning
through the safety control box as long as this is
installed on the lower part of the tank. Provide an air inlet by opening a hot water tap.
3 - P&T VALVE
Check the operation of the P&T valve every year
and rinse it by briefly bleeding it several times.
A safety valve that is not working correctly may
cause damage due to excessive pressure.
If necessary, replace it if it stops working correctly or
begins to leak (permanent flow through the valve).
