ANTI-FREEZE MODE.
With this setup the device maintains temperature that does not allow
the water freeze in it. The electrical supply of the appliance should
be turned on and so must be the appliance. The safety valve and the
pipe between the valve and the appliance must be protected from
freezing. In case that for some reason the electrical supply is cut off,
there is a risk of freezing of the water in the water tank. For this reason
we recommend draining the water out of the appliance before long
absences (longer than a week).
SUMMER MODE.
This setup is suitable for the summer season. And is characterized
with lower maximum temperatures for heating the waters secures an
economic working regime for the appliance.
WINTER MODE.
This setup is suitable for the winter season and is characterized with
high maximum temperatures for heating the water in the appliance.
This mode secures maximum quantity of water with comfortable
temperature.
ANTIBACTERIAL MODE.
It is recommended that once per month the appliance should be
placed in this mode for a period of 1 day with the aim to ensure higher
•
hygiene of the used hot water. Use this regime:
•
when you turn on a new appliance
when you have an appliance that has not operated for a period
•
longer than a week
during a check with an anode tester (see p. 3 of this paragraph)
It is admissible that the appliance works continuously in this regime if
you need more hot water.
Fig. 2a indicates the direction of rotation of the knob for the other
models with externally adjustable thermostat.
IMPORTANT: Models that do not have thermostat control
knobs have automatic water temperature preset by the
manufacturer (fig.2d).
ANODE TESTER - (with models, having an integrated tester).
3.
This facility serves for the identification of the current state of
magnesium anode and indicates the need for its replacement. The
anode tester is secured with button 4 and light indication 5 next to it
(Fig.2a, 2b).
The state of the anode protector can be controlled by pressing button
4. When the illuminating indicator, besides it is lit in a blinking GREEN
color, this means that the ANODE PROTECTOR functions in a normal,
usual mode and protects your appliance from corrosion. When the
illuminating indicator is lit with a blinking RED color, this means that
the ANODE PROTECTOR is worn out and should be replaced.
IMPORTANT: The changing of the anode protector is done by a
qualified technician.
The anode tester is able to read correctly the state of the
anode protector only when the temperature of the water in
the tank is higher 60°C. For this reason, before pushing button 4 (TEST),
make sure that the water in the tank is heated enough and that no
quantity has been drained out of it with cold water having been
poured into it before that. The thermostat should be set to the
maximum temperature.
Protection according to the temperature (valid for all models).
4.
The appliance is equipped with a special facility (thermal circuit-
breaker) for protection against over-heating of the water, which
is switching off the heater from the electricity network, when the
temperature reaches too high values.
English
When this device operates, it does not self-reset and the
appliance will not work. Please call an authorized service for
solving the problem.
MODELS EQUIPPED WITH A HEAT EXCHANGER
VIII.
(SERPENTINE TUBE) - FIG.1D AND TABLE 2.
These water heaters allow energy savings during the year's heating
season. This is achieved by the built in heat exchanger (boiler tube).
With its assistance, the water heaters may heat water without
consuming electricity, by using local or central water heating.
Maximum temperature of the heat carrier: 80°C.
The water heaters equipped with a heat exchanger offer three
possibilities for water heating:
Via an electric heating element
1.
Via a heat exchanger /boiler tube/
2.
Combined heating - via boiler tube and electric heating element
3.
Mounting:
In addition to the mounting manner outlined above, especially for
the latter models, it shall be required to connect the heat exchanger
to the heating installation. The connections are to be carried out in
observance of the direction indicated by the arrows on Fig. 1d.
We recommend you mount stopcocks at the heat exchanger's entry
and exit points. By stopping the flow of the thermophore via the
lower (stopcock) you shall avoid the unnecessary circulation of the
thermophore during periods of use only of the electric heating
element.
Upon disassembly of you water heater equipped with a heat exchanger
you must close both stopcocks.
The usage of dielectric bushings for connecting the heat
exchanger to an installation of copper pipes is obligatory.
For ensuring minimal corrosion, pipes with a limited diffusion
of gasses must be used in the installation.
IX.

PERIODIC MAINTENANCE

Under normal use of the heater, under the influence of high
temperature, lime scale /the so-called lime scale layer/ is deposited
upon the heating element's surface. This worsens the heat exchange
between the heating element and water. The heating element's surface
temperature increases along /of boiling water/. The thermoregulator
begins to switch on and off more frequently. A ''deceptive" activation of
the thermal protection is possible. Due to these facts, the manufacturer
recommends preventive maintenance of your water heater every two
years by an authorized service center or service base. This protective
maintenance must include cleaning and inspection of the anode
protector (for water heaters with glass-ceramic coating), which shall be
replace with a new one if need arises.
In order to clean the appliances use a damp cloth. Do not clean with
abrasive or solvent content detergents. Do not pour water over the
appliance.

FOR ALL CONSEQUENCES CAUSED BY NOT OBEYING THE
INSTRUCTIONS, GIVEN HEREBY.
Instructions for protecting the environment
Old electric appliances contain precious materials and thus
should not be thrown together with the household litter. We
kindly ask you make your active contribution for protecting the
resources and the environment by handing over the appliance in
the authorized buy-back stations (if such exist).
