The light indicators do not light when:
The electrical switch of the appliance is switched o
The appliance power supply from electrical main is switched o
Protection according to the temperature is switched o – see item
3 below
2.3. Temperature setup (for models with adjustable thermostat)
This setup allows the gradual setting of the desired temperature,
achieved by using a handle on the control panel. Turn the knob to the
upward indication, in order to increase the temperature of the hot
water.
Place the thermostat knob in position for maximum
temperature (unless it is on this position constantly), for period
of one day each month. This ensures higher hygiene of the used hot
water.
IMPORTANT: Models that do not have thermostat control
knobs have automatic water temperature preset by the
manufacturer.
ANTI-FREEZE MODE (g.2). 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 o, 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).
3. Protection according to the temperature (valid for all models).
The appliance is equipped with a special facility (thermal circuit-
breaker) for protection against over-heating of the water, which
is switching o the heater from the electricity network, when the
temperature reaches too high values.
When this device operates, it does not self-reset and the
appliance will not work. Please call an authorized service for
solving the problem.
VIII. MODELS EQUIPPED WITH A HEAT EXCHANGER
(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 oer three
possibilities for water heating:
1. Via an electric heating element
2. Via a heat exchanger /boiler tube/
3. Combined heating - via boiler tube and electric heating element
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 ow 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 diusion
of gasses must be used in the installation.
IX. PERIODIC MAINTENANCE
Under normal use of the heater, under the inuence 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 o 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.
THE MANUFACTURER DOES NOT BARE THE RESPONSIBILITY
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).
