(*) At the first use it is possible to have all of these signals at the same time as the
potential of the enameled walls of the boiler could be close to the protection
limit.

Warning! In case the alarm for abnormal work of the hybrid anticorrosion
system is turned on according to the error codes in table. 4, please
immediately contact your installer, an authorized service station or the dealer from
whom you purchased the appliance – in order to fix the problem.
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.
e
Position
(Energy-save mode) – At this mode, water temperature reaches
up to approximately 60°С. Heat losses are reduced in this way.
Fig. 2 indicates the direction of rotation of the knob for the other models with
externally adjustable thermostat.
Attention! 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.
4. 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.
Attention! 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. 1B.
Technical parameters (table 3):
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.

PERIODIC MAINTENANCE

IX.
Warning! In case of damage – if the appliance doesn't heat up or there
is vapour coming out of the hot water tap, immediately turn off the
power and contact your installer, an authorized service station or the dealer
from whom you purchased the appliance.
Warning! In case the alarm for abnormal work of the hybrid anticorrosion
system is turned on according to the error codes in table. 4, please
immediately contact your installer, an authorized service station or the dealer from
whom you purchased the appliance – in order to fix the problem.
In the conditions of normal use of the water heater, under the influence of high
temperature, limestone (the so-called lime scale) deposits on the surface of the
heating element. This worsens the heat exchange between the heating element
and the water. The temperature on the surface of the heating element and around
it increases. Specific noise can be heard – 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 centre or service facility, this service remaining at the customer's expense.
Notice: The appliance's technical preventive maintenance must include cleaning
and inspection of the anode protector. If the wear of the anode protector is more
than 50% (fifty percent) the magnesium anode shall be replaced with a new one,
provided by the manufacturer.
Notice: To clean the appliance, use a damp cloth. Do not use abrasive or solvent-
containing detergents.
If it is established that the instructions in this user manual are not followed,
the appliance's warranty shall be null and void.
The manufacturer does not bear responsibility for any consequences
arising from non-adherence to these instructions.
Instructions for protection of the environment
Old electric appliances contain valuable materials and must not be
disposed of with the domestic waste! Please contribute actively for
the protection of the resources and the environment and dispose of
the appliance in the buy-back centres organized for this purpose
(if such are available).
