Appliance Description; Settings; Cleaning, Care And Maintenance - AEG EWH 30 Trend Operation And Installation

3. Appliance description

The closed (pressure-tested) appliance heats DHW elec-
trically. You can adjust the temperature using the temper-
ature selector. Subject to the power supply, the water is
heated automatically to the required temperature. You can
read the current DHW temperature from the temperature
indicator.
The internal steel cylinder is coated with special "Co
Pro" enamel and is equipped with a protective anode.
The anode protects the internal cylinder from corrosion.
Frost protection
The appliance is also protected against frost by the tem-
perature setting "*", provided that the power supply is
guaranteed. The appliance switches on in good time and
heats the water. The appliance does not protect the water
supply lines and the safety valve from frost.

Operation - for users and contractors
4.1 Holiday and absence
» If the appliance is not to be used for a few days, set
the temperature selector to a position between the
frost protection and energy saving settings.
» If the appliance is not to be used for a longer period,
set it to frost protection to conserve energy. If there
is no risk of frost you may disconnect the appliance
from the power supply.
» For reasons of hygiene, heat up the content of the
water heater once to above 60 °C before initial use.
5. Cleaning, care and
maintenance
» Have the electrical safety of the appliance and the
function of the safety valve regularly checked by a
qualified contractor.
» Have the protective anode initially checked by a
qualified contractor after the first year. The qualified
contractor will then determine the intervals at which it
must be checked thereafter.
» Never use abrasive or corrosive cleaning agents. A
damp cloth is sufficient for cleaning the appliance.
Scaling
» Almost every type of water will deposit lime at high
temperatures. This settles inside the appliance and
affects both the performance and service life. The
heating elements must therefore be descaled from
time to time. A qualified contractor who knows the
local water quality will tell you when the next service
is due.
» Check the taps/valves regularly. You can remove
limescale deposits at the spouts using commercially
available descaling agents.
» Regularly activate the safety valve to prevent it from
becoming blocked e.g. by limescale deposits.
