Care
■ Only clean the units with a damp
cloth.
(adding, for instance, a liquid
household cleaner.)
Do not use harsh, scouring or
solvent-based cleaners .
Care and maintenance
This will ensure that your
equipment always operates reliably!
NOTE
Maintenance
■ We recommend concluding a
maintenance contract with a
specialist firm, which includes annual
maintenance services.
■ Regularly check the function of
the safety valve.
The expansion water amount at
maximum heat (approx. 80°C) represents
approx. 3.5% of the tank capacity.
When the safety valve test knob is lifted
or in the “Test” position, the water must
flow unhindered out of the safety valve
body into the drainage funnel.
! ATTENTION
This can cause the cold water
supply and parts of the storage tank
connection fitting to become hot!
Water should not drip from the safety
valve if the tank is not hot or if hot water
has been removed. If this does occur,
either the pressure in the water pipe is
greater than the permitted value or the
safety valve is defective. If the pressure in
the water pipe is higher than permitted,
a pressure relief valve must be used.
If the water is hard and when operating
the tank at more than 60°C, install a
standard descaling device upstream from
the tank or regularly clean the fin-tube
heat exchanger. The cleaning must be
done by a qualified specialist. To do so,
proceed as follows:
1. Remove the fin-tube heat exchanger.
2. . Carefully knock the limescale off or
clean the fin-tube heat exchanger
in a container filled with limescale
solvent.
3. Flush the fin-tube heat exchanger
thoroughly.
4. Replace the fin tube heat exchanger.
