8 Inspection and maintenance
Regular inspection of the hot water storage tank guarantees a long
service life and fault-free operation.
An external current anode is only necessary if the filling water is very
hard and contains chloride (>/= 250 mg/l). Please contact your local
water supply company for further information.
DANGER: RISK OF ELECTROCUTION
Touching live parts can result in an electric shock and lead
to potentially fatal injuries and burns.
▪ If there is an electric immersion heater or an external
current anode installed in the hot water storage tank,
these components must be isolated from the power sup-
ply before starting work (e.g. fuse, main switch switched
off and secured against inadvertent switching on again).
DANGER: RISK OF ELECTROCUTION
All work performed on live components must be carried out
in accordance with the proper procedures, otherwise there
may be a danger to the life and health of personnel and the
function may be impaired.
▪ Rectification of damage to live components may only be
carried out by heating specialists authorised and recog-
nised by the energy supply company.
8.1 Annual inspection
If present:
▪ Carry out a functional inspection of the electric immersion heater
by checking the temperature display and the switching states in
the individual operating modes:
▪ Electric immersion heater: See the associated installation and
operating instructions.
▪ Visual inspection of the general condition of the hot water storage
tank.
▪ Visual check of connections and pipes. In the event of damage,
determine the cause.
