Instructions for use and maintenance
EN
The control lamp lit on when there is supply voltage from
electrical main. It does not lit on when there is not supply
voltage or the thermal cut-out (temperature protection) is
switched off (see 3 below).
•
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.
•
Operation mode selection for models displayed on Fig.2a :
Four positions indicate different operation modes of the device:
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.
e
ENERGY-SAVE MODE.
At this mode, water temperature reaches up to
approximately 60°С. Heat losses are reduced in this way.
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.
Fig. 2 indicates the direction of rotation of the knob for
the models with externally adjustable thermostat.
IMPORTANT: Models that do not have thermostat
control knobs have automatic water temperature
preset by the manufacturer.
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 off 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)
These are appliances with inbuilt heat exchanger and are
intended to be connected to the heating system with
maximum temperature of the heat carrier of 80°C.
The control over the flow through the heat exchanger is a
matter of solution for the particular installation, whereby
the choice should be made at its design (e.g. external
thermostat that measures the temperature in the water
tank and operates a circulation pump or a magnet valve).
Water heaters with a heat exchanger provide the
opportunity for the water to be heated in two ways:
1.
by means of a heat exchanger (coil) – a primary way of
heating the water,
2.
by means of an auxiliary electrical heating element
with automatic operation, built in the appliance – it is used
only when additional heating of the water is needed or in
case of repairs to the system of the heat exchanger (coil).
The proper way of connecting the appliance to the electric
network and how to work with it has been specified in the
previous paragraphs.
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. 1c.
Technical parameters ( table 4) :
Surface of serpentine [m²] - S;
Volume of serpentine [l] - V;
Operational pressure of serpentine [MPa] - P;
Maximum temperature of heat carrier [°C] - Tmax.
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.
There is a connexion with internal thread of ½” welded
to the water tank for the purposes of installing thermal
probe – marked with „TS”. The appliance is fitted with
brass pocket for a thermal probe which should be
screwed into the aforesaid connexion
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.

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).
