CAUTION: Before any intervention into the interior of the water heater,
disconnect it from the power supply network!
OPERATION AND MAINTENANCE
After connecting to the water and power supply, the heater is ready for use.
By turning the knob of thermostat at the front side of the protecting cover, the wished
temperature of water between 25 °C and 75 °C is chosen. We recommend the
adjustment of the knob to the position "e". Such an adjustment is the most economic;
with it the temperature of water shall be about 55 °C, the excretion of lime-stone and
thermal loss shall be smaller as by adjustment to higher temperature. The operation
of electric immersion heaters is shown by pilot light.
When the heater shall not be used during a longer time, its contents must be
protected against freezing so that the power supply (electricity) shall not be switched
off, but the thermostat knob shall be adjusted to the position "*". With this adjustment
the heater shall maintain the water temperature by 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. For this purpose, a special fitting (T
- fitting) 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 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 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 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.
