MAINTENANCE
Corrosion protection: Every water heater features an
enamelled water tank with additional corrosion
protection. This corrosion protection consists of a
magnesium anode (sacrificial anode). The anode is a
wearing part (i.e. it wears out during normal operation
of the unit). The average life span is about 3 years,
which depends particularly on the operating mode of
the appliance as well as the characteristics of the water
to be heated. The condition of the anode should be
checked at regular intervals and, if necessary, replaced
by a service specialist authorized by the manufacturer
or distributor.
Compliance with the deadline and the timely renewal
of the anode are important conditions for efficient
corrosion protection of the water tank. The exam-
ination and the renewal of the anode are not included
in the warranty obligations of the manufacturer nor the
dealer. To ensure the safe operation of the water heater
in regions with calcareous water, it is recommended to
clean the water tank regularly from accumulated
limestone. Such cleaning should be carried out at least
every two years, or more frequently in regions with
calcareous water. Deposits on the enamel coating do
not need to be scraped off, just wiped off with a dry
cotton cloth. The regular cleaning and removal of the
limescale is essential to ensure the safe operation of
the appliance. Whilst cleaning the anode of the
enamelled water tank should also be checked. These
services are not part of the warranty scope and must be
carried out by qualified persons. The regulations for the
inspection of the anode protection and renewal of the
anode, as well as the removal of the collected lime-
stone, must be observed both during and after the
expiration of the warranty period for the appliance.
Combined check and pressure relief valve: To
guarantee the proper and safe operation of the water
heater, regularly check the combined check and
pressure relief valve for reduced permeability. For this
purpose, lift the small lever and wait approx. 30-60
seconds until a strong stream of water flows out of the
valve opening on the side. This check must be carried
out after filling the tank with water, at 2-week intervals
and after failure and restoration of the water supply. If
no water or only a thin stream flows out of the valve
opening, this indicates a malfunction. A possible con-
tamination of the water pipe might be present. The
fault must be eliminated before commissioning.
Cleaning: The outer casing and the plastic parts of the
water heater should only be cleaned with a lightly
moistened cotton cloth, free of aggressive and/or
scouring agents. Do not clean the appliance with a
steam cleaner. The water heater may only be put back
into operation after the moisture has completely
vanished.
MALFUNCTION
In case of a malfunction during the operation of the
water heater, disconnect all live wires from the
appliance and contact the manufacturer or your
distributor.
