(it is obligatory) and the earthing wire should be connected to the connection wearing the earthing
sign.
Touch protection class of the appliance: I.
The covers closing electric accessories provide suitable protection against accidental touch of
active electric parts being under power during operation.
Maintenance: Attention! Before starting repair or maintenance work, the appliance should be
separated from electric network. Any maintenance or repair operation on the appliance
should be performed by a professional technician. During repair or maintenance work, the
appliance should be re-installed into its original, out-of-factory state." It is highly
recommended to have the professional technician document the repair in order to preserve
warranty of the appliance.
IT IS FORBIDDEN TO OPERATE THE WATER HEATER WITHOUT PROTECTIVE
EARTHING!
The protective earthing has to comply with dispositions of the IEC 60364.
The electric appliance has to contain a one-pole isolation or sectioning unit (connector) mounted
after the water heater, which makes the separation of the opening contacts of the connector possible
at a distance of at least 3 mm. The water heater has to be connected to the system through a fix
connection.
THE THERMOSTAT
This water heater is an appliance of a really good quality, built, regulated and controlled in a careful
way. Its only task is to maintain the temperature of the water at a pre-selected level, or to limit
moves in water temperature. The thermostat of the water heater is stamped, which means that no
possible (re)controls or reparations can be made on it over the work the manufacturer has performed
on the appliance; except for normal control executed through turning the indicator, which can only
be performed by a professional technician after putting the appliance into operation in a
voltage-free state. Neglecting this instruction causes losing guarantee and warrant rights. In case of
any difficulty (some kind of failure), the thermostat has to be simply replaced. The water heater
must be handled with utmost care.
In order to reach efficient use of electric energy, the operating temperature of the water heater must
o
be set around 65 C, which increases resistance to corrosion and decreases the danger of scale
deposit. Up to obtaining the set temperature, clamps P-1 are closed, while after this point, clamps P-
2 are closed.
In case of appliances of type IDE...F and IDE...S, the controlling of electric heating and
temperature is performed by a separate temperature controller. In case of electric heating, it
is not possible to control the temperature of the water to be heated with the help of the button
of the controller mounted onto the outside cover.
THERMAL SAFETY DETACHMENT OF THE HEATING CIRCUIT
The thermal safety of the water heater must be completed at boiler circuit side.
THERMAL SAFETY (for types IDE...F and IDE...S)
The water heater is protected by a safety unit built in the thermal regulator against too high
temperatures in case of electric heating.
ANODE PROTECTION
The tank made of enameled steel plate is protected by a magnesium anode against corrosion.
