2 OPERATION AND FITTING INSTRUCTIONS

2.1

OPERATING CONDITIONS

The tank shall only be used in accordance with the conditions specified on the power 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 temperature at the place of heater installation must be higher than +2 °C; and the room
must not freeze. 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.
If water is strongly calcareous we recommend that any of the common decalcifying devices was
installed with the appliance, or that the thermostat was set to the minimum operating
temperature of 55 °C (setting to position „OPTIMUM") - Figure 10. For proper operation,
drinkable water of adequate quality shall be used. To avoid potential sediments, we recommend
that the device was installed together with a water filter.
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. The minimum diameter of 4 bolts for suspending the
heater is 8 mm. When mounting the anchor bolts follow the manual provided by the anchor
bolts' manufacturer.
Thermostat and no other part of the control panel is not a bearing part which can be used for
any handling with 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 available under the heater. When
mounted directly under the ceiling, the distance from the ceiling has to be 50 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.
