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.
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 appliance has to be mounted
at a convenient place, it means that the appliance must be easily available 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 devices
was installed with the appliance, or the thermostat to be set to 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 NTR/Z
series 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. The OKCV NTR series water heater shall
only be mounted in horizontal position so that, from the front view, the right edge of the
heater was placed at least 600 mm from the opposite wall. In combined heaters, elbows
have to be attached to the heating water inlet and outlet and, by turning them, determined
the mounting either from the right or from the left (Figure 10). 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.
If the hot water heater is mounted in a tight, small space, or in an intermediate ceiling, etc.,
you have to make sure that the connecting side of the appliance (connections to water
supply, area for electric plugging) remained accessible and no heat accumulation occurs.
Free space of up to 600 mm from the bottom edge of the heater has to be available under
the heater.
