2 OPERATION AND FITTING INSTRUCTIONS
2.1 OPERATING CONDITIONS
The tank shall only be used in accordance with the conditions specified on the performance
plate and in instructions for electric wiring. Besides legally acknowledged national
regulations and standards, also conditions for connection defined in local electric and water
works have to be adhered to, as well as the installation and operation manual. The room, in
which the appliance will be operated, must be frost-free. The temperature in the heater
installation location must not exceed +2 °C. The appliance has to be mounted at
a convenient place; it means that the appliance must be easily accessible for potential
necessary maintenance, repair or replacement, as the case may be.
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.
If water is strongly calcareous we recommend that any of the common decalcifying device
was installed with the appliance, or the thermostat to be set to the minimum operation
temperature of 60
used. To avoid potential sediments we recommend that the device was installed together
with a water filter.
2.2 WALL MOUNTING
Prior to mounting, check the loading capacity of the wall and, depending on the type of
masonry, choose a suitable anchorage material, or reinforce the wall, if needed. The water
heater shall only be mounted in vertical position so that the lower edge of the heater was
placed at least 600 mm above the floor (Figure 1). In combined heaters, elbows have to be
attached to the heating water inlet and outlet and, by turning them, the mounting either
from the right or from the left has to be determined (Figure 2). With regard to various types
of carrying masonry and broad assortment of special anchorage material available at the
market, we do not provide heaters with this material. The anchorage system has to be
selected individually, depending on the conditions. We recommend an authorised company
perform mounting on the wall and anchorage, or discuss the anchorage with a professional.
