OPERATION AND MAINTENANCE
The water heater is ready for use once it has been connected to water and power. By tur-
ning the thermostat knob on the front side of the protective cover, water temperature can be
set between 25 °C, position " " and 75 °C, position " ". We recommend that the knob
be set to position "
This way the water temperature is maintained at 55 °C. The operation of the heater at this
temperature level also results in reduced build-up of calcium and lime, as well as reduced
heat loss than is the case at higher temperatures. Due to safety reasons you can optional-
use for longer periods of time, it should be protected from freezing by setting the temperature
to "
". Do not disconnect the power. Thus the temperature of the water in the tank is main-
tained at about 9 °C. Should you choose to disconnect the power, the water heater should be
thoroughly drained before the onset of freezing conditions. The exterior of the water heater may
be cleaned with a mild detergent solution. Do not use solvents and abrasive cleaners.
Regular preventive maintenance inspections ensure faultless performance and long life of your
heater. The first of these inspections should be carried out by the authorised maintenance ser-
vice provider about two years from the date of installation in order to check the wear of the
protective anticorrosion anode and remove any build-up of calcium and lime as required. The
build-up of calcium and lime in the water heater depends on the quality, quantity and tempera-
ture of water flowing through the heater. The maintenance service provider shall also issue a
condition report and recommend the approximate date of the next inspection.
In the event of the heater breaking down, you are kindly requested to contact the
authorised maintenance service provider located closest to you. Please do not
attempt to carry out any repairs yourself.

The operation of the heating element is indicated by the
light indicator that stays on until the temperature in the
tank has reached the set level or until the heater has been
deliberately switched off. When the water heater is not in
