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.

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 between 25°C, position "
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.
For safety reasons setting of optional highest temperature in the water heater is possible according to the below
instructions:
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 from frost 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
