WALL MOUNTING (applies to NTR/Z & OKCV NTR only)
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 (Fig. 5, 6). 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 (Fig. 1).
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.

ELECTRIC INSTALLATION
Check the insertion of the thermostat sensor in the thermowell, the so-called insertion all the way.
The heater can be connected to any hot water heating boiler up to the power output of 50 kW. Electrically, the heater is
powered directly by boiler with 230 V/50 Hz control voltage.
interconnection. Connecting terminals are identified on the terminal board of the heater.
