OPERATION AND MAINTENANCE

After connecting to the water and power supply, the heater is ready for use. By
turning the thermostat knob, water temperature can be set between 25 °C and 75 °C.
We recommend that the knob be set to the position "e" 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 from the heater is drained through the
inlet pipe of the heater. For this purpose, a special fitting (T-fitting) must be mounted
between the safety valve and the heater inlet pipe, or a discharge tap. The heater can
be discharged directly through the safety valve, by rotating the handle or the rotating
valve cap to the same position as for checking the operation. Before discharge, make
sure the heater is disconnected from the power supply, and 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 flange, through the heating flange opening.
The external parts of the water heater can 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 first of these inspections should be carried out by the
authorised maintenance service provider about three 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 result of quality, quantity and temperature of water
flowing 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.
