2 PERATION AND FITTING INSTRUCTIONS

2.1 OPERATING CONDITIONS

The heater may only be used in accordance with the conditions specified on the nameplate
and the instructions contained in this manual. Besides the legally acknowledged national
regulations and standards, also conditions for the connection defined in local electric and water
works have to be adhered to, as well as the installation and operation manual.
The temperature at the place of heater installation must be higher than +2°C; and the room
must not freeze. The heater has to be mounted at such a place that can be counted
with as handy; it means that the appliance must be easily accessible for possibly necessary
maintenance, repair or replacement, as the case may be.
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°C (Figure 6). For proper operation, drinkable water of adequate quality shall
be used.

2.2 WALL MOUNTING

Prior to the mounting check the bearing capacity of the wall and the material it is made of,
considering the weight of the heater filled with water. Depending on the wall material choose
adequate fixtures. Should you have any doubts regarding the wall bearing capacity, consult
the suspension with a building specialist.
Neither the control knob of the thermostat, nor another part of the control panel is a bearing
part which may be used for any handling of the heater!
If the hot water heater is mounted in a tight, smaller 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 left available under the heater.
When mounted directly under the ceiling, the distance from the ceiling has to be 100 mm
at least.
If the water heater is mounted in enclosed areas, inter-ceilings, built-in structures and recesses,
ensure sufficient access to service fittings, electrical terminal boards, anodes and manholes.
Minimum spacing from manhole is 600 mm.
The heater is mounted in vertical position directly on the wall. Fastening screws must have
guaranteed spacing t = 180 mm.
