Do not try to repair the failure yourselves. Seek either expert or service help. It does not take much for an expert to
remove the defect. When making a repair appointment, report the type and serial number you find on the performance
plate of your water heater.
12. FIRE-FIGHTING REGULATIONS FOR INSTALLATION AND USE OF HEATER
We would like to emphasise that the heater must not be connected to power supply if work involving flammable
liquids (petrol, spot remover) or gases, etc., is performed nearby.
13. USE AND MAINTENANCE OF HEATER
Once connected to water and power network, the heater is ready for use.
By turning the thermostat knob located on the front side of the protective guard set the desired water temperature up to
75°C. We recommend that the knob was set to position "e". Such connection is most economic; temperature of water is
about 55°C, thermal losses and scale formation will be lower than if set to higher temperature.
The electric heater operation is indicated by a control light that is on until the water in the heater heats up to the selected
temperature, or until switched off as scheduled. Due to heating, the volume of water increases, which causes water
dripping from the combination faucet pipes. You will not prevent water from dripping by strong tightening of the handle
on the combination faucet but you may damage the faucet.
If you do not intend to use the heater constantly, you need to protect the water in the heater by not discontinuing the
power totally and setting the thermostat selector to position "*". At such setting the heater is maintained at the
approximate temperature of 9°C. If you take the heater off the power supply, you have to drain the water from it if there is
a risk that the water inside freezes. Clean the outer parts of the appliance with a mild detergent solution. Do not use
thinners or other aggressive cleaning agents. Through regular service inspections you will ensure trouble-free operation
and long service life of the heater. We recommend that the first inspection of the heater was performed by a specialist,
approximately after two yours following its putting in operation. During the inspection the scale, that will accumulate
inside the heater depending on the quality, amount and temperature of the water consumed, will be removed as needed.
During the inspection of the heating element, the service technician will advise of the date of the next inspection, taking
into consideration the found condition of the appliance.
WARNING: Prior to any intervention in the inside of the heating element, the appliance has to be disconnected
from power supply!
Do not attempt to repair the heater by yourselves, call the nearest authorised service centre to do so.
