CAUTION: Prior to each reach in the inner of the water heater it must absolutely be
disconnected from the electric network!
USE AND MAINTENANCE
After the connection to water and electric network the water heater is ready for use. Temperature
of water in the appliance is automatically controlled by the thermostat which is adjusted by the
manufacturer. The adjustment can be modifi ed by turning of the adjustment screw upon the
thermostat in the inner of the water heater. The adjustment range reaches between 20°C and
75°C. We do not recommend any change of the manufacturers adjustment, thus this ensures
the most economical consumption of electric energy and the smallest excretion of lime-stone.
The operation of electric immersion heater is shown by pilot light. 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 heater shall not be used during a longer time, it must be disconnected from the
electric network. At any risk for freezing of water in the water heater, the water must be emptied
from it. Water is discharged from the heater via the inlet pipe. To this purpose, a special fi tting
(T-fi tting) shall 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,
quantity 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.
