CAUTION: Prior to each reach in the inner of the water heater it must absolutely be
disconnected from the electric network!
USE AND MAINTENANCE
The water heater is ready for use once it has been connected to water and power. By turning the
thermostat knob, water temperature can be set between 25° and 75°C. We recommend that the
knob be set to the position "eco" ensuring the most economic operation of the water heater. This
way, the water temperature is maintained at 55°C while the operation also results in less lime
sediment as well as in less heat losses than is the case at higher temperatures.
The light indicator shows the operation of the heating element. On the casing of the water heater
a bimetal thermometer is mounted, pointing clockwise (to the right) whenever there is hot water
in the water heater. When the water heater is not in 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 water is maintained at about 10°C. Should you choose to disconnect the power,
the water heater should be thoroughly drained before the onset of freezing conditions. Water
is discharged from heater via the inlet pipe. To this purpose, a special fi tting (T-fi tting) must
be mounted between the relief valve and the heater inlet pipe, or a discharge tap. The heater
can be discharged directly through the relief valve, by rotating the handle or the rotating valve
cap to same position as for checking the operation. Before discharge, make sure the heater
is disconnected from the power supply, open the hot water on the connected mixer tap. After
discharging through the inlet pipe, there is still some water left in the water heater. The remaining
water will be discharged after removing the heating fl ange, through the heating fl ange opening.
The external parts of the water heater may be cleaned with a mild detergent solution. Do not use
solvents and abrasives.
Regular preventive maintenance inspections ensure faultless performance and long life of
your heater. The fi rst of these inspections should be carried out by the authorised maintenance
service provider about two years from installation in order to inspect the wear of the protective
anticorrosion anode and remove the lime coating and sediment as required. The lime coating
and sediment on the walls of the tank and on the heating element is a product of quality, puantity
and temperature of water fl owing through the water heater. The maintenance service provider
shall also issue a condition report and recommend the approximate date of the next inspection.
Never try to repair any possible faults of the water heater by yourself, but inform about it the
nearest authorised service workshop.
