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.
