Water heaters with heat exchanger. The water heaters of these
models secure an energy efficient operation thanks to their built-in
heat exchangers. The heat exchanger(s) outlets locations and
their basic installation distances are shown on Fig. 4, 5, 6, 7 and
Tables 2 and 2a. By using a heat exchanger bigger quantities of
water inside the water container can be heated through an
additional alternative energy source, i.e. local or central heating
system, solar collectors and other similar sources. For more
efficient heat exchanger use it is recommended to move the heat-
transfer liquid with a circulation pump. For heat-transfer liquid can
be used water with composition and index values within the levels
laid down in the regulations related to water or a dedicated
aqueous solution which is not aggressive to heat exchanger

material. The heat-transfer liquid must be with temperature not
higher than 85 °С and in its circuit must be installed a control
device set at this temperature in order not to allow thermal cut-out
of the electrical heating element during normal operation. The
pressure of the heat-transfer liquid in the heat exchangers must
not exceed the stated working pressure of the heater.
WATER HEATER INSTALLATION ON THE WALL
OF THE PREMISE
The water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0 °C. The
availability of a siphon on the installation for waste waters as
during normal usage of the water heater, water may leak from the
safety valve aperture. At the same time the siphon will facilitate the
water tank maintenance, prevention and servicing operations
when water needs to be drained out of the water tank.
The type and nature of wall construction material, the appliance
dimensions, the way of fixing it, the location of its fixing elements
and tubes, its protection against dripping water must be taken into
account when choosing the proper place for installation. All these
data are duly marked on the appliance production plate with its
serial number. The appliance must be mounted where it is
protected against water dispersion or water pouring over. In order
to reduce heat loss it is recommended to keep minimum distance
between the heater and the places where the hot water is used.
If you purchased a water heater with factory-fitted power cord with
plug, the unit cannot be installed in a wet premise! The location of
the device must comply with the requirements for the electric
installation and its contact. Refer to the electrical connection of this
instruction.
It is obligatory that there are spaces provided between the
appliance and the surrounding walls and the ceiling of the premise,
as follow:
џFor vertical water heaters – at least 70 mm between the
appliance and the ceiling; at least 50 mm between the
appliance and the side wall; at least 350 mm below the
appliance to facilitate servicing and possible repair.
џFor horizontal water heaters – at least 70 mm between the
unit and the ceiling; at least 70 mm between the side cover
(outlets excluded) and the wall; at least 350 mm between the
electric part plastic cover and the wall to facilitate the
servicing and possible repair, and a sufficient distance below
the unit for installation of water connections and drain the
water from the tank.
џIn tanks with heat exchangers must be kept a distance from
the coil terminals side and the joints for additional
thermostats necessary to connect the additional control and
safety units.
Water heater should be installed steadily on the wall of the
premises. For this purpose steel bolts (studs), tightly fixed in the
wall, with diameter 10-12 mm are used. The fixing elements should
be secured against pulling aside the wall – they should be anchor
or passage bolts (depending of the wall construction material). It is
recommended that the elements on which the heater will be
suspended are designed for three times greater loads than the
appliance total weight and located in the water therein. Installation
of the water heater on decorative walls (made of single bricks or of
other light materials) is strictly forbidden. On Fig. 1,2,3,7 and in the
tables are shown the distances between the bolts (studs) for
mounting the units.
WARNING! The bearing plates of horizontal water heaters
must be securely clamped to the premise wall. Under the bolts
heads (nuts on studs) must be placed support washers!
WARNING! Non observance of the requirements for fixing the
water heater on the wall may cause damages of the appliance,
damages on other appliances and the premises, where the
device is located, as well as corrosion of the casing or even
more serious failures and damages. In such cases eventual
failures and damages are not a subject to manufacturer and
seller warranty liabilities and will be at the expense of the party
which has not observed the present manual instructions.
The water heater mounting to the premise wall must be completed
only by a specialist.
WATER HEATER CONNECTION TO THE WATER
SUPPLY NETWORK
The plumbing to which the water heater will be connected, as well as
any other elements included in it shall have to withstand sustained
water temperatures above 80°C and for short periods - above
100°C, as well as to pressure at least twice high the appliance
working pressure.
Upon connection of the water heater to the water supply grid, the
arrows and indication rings around the water heater pipes for hot
and cold water must be observed (inlet and outlet pipes). With an
arrow towards the pipe and blue color is marked the cold water
pipe and an arrow starting from the pipe in red color - the hot water
pipe. Some appliances pipes are additionally marked with badges.
The pipes outlets are with threading 1/2". A schematic diagram for
water heater connection is shown on Fig 8. When the water heater
works at the water pipe tank pressure and that of the safety valve.
In the event where the conduit pressure is greater than 0,5 MPa it
shall be required the installation of reduce valve (pressure-
reducing valve). Where local regulations require use of additional
devices that are not included with the unit supply set and are not
placed in the packaging, these must be purchased and installed
according to regulations.
The water heater is equipped with a combined check-safety valve.
The latter is factory-fitted on the cold water pipe. Exception is made
for horizontal mounted water heaters with heat exchangers or
without and their modifications, where the pipes for hot and cold
water pass through the cylinder of the shell of the unit. For these
models the combined check-safety valve is located in a bag
attached to the appliance packaging and MUST OBLIGATORY be
mounted on the cold water pipe. During that installation follow the
arrow on its hull showing the direction of water flow through it.
WARNING! It is FORBIDDEN to install any kind of shut-off
fittings between the combined valve and the water heater! It is
absolutely forbidden to obstruct the lateral opening of the
combined valve and/or to block its lever!
Where the plumbing pipes are copper or of another metal, other
than that of the water tank, or where brass fasteners are used, it is
obligatory to install on the water tank inlet and outlet non-metallic
couplings (dielectric fittings).
ATTENTION! For units with heat exchangers. Any additional
tubular outlets (excluding those of the serpentines) that will be
connected with the plumbing, and the holes for additional
thermostats and / or thermomanometer must be closed with a
package insert or other suitable for the purpose. The connections
must be sealed for a water pressure of at least 1.6 Mpa.
It is recommended to set up a draining system for any dripping

EN
10
from the combined valve side opening. The draining pipe must
have a constant downward slope and located in frost secure
environment and its ends to be constantly kept open to the
atmosphere.
Once the water heater is connected to the water supply main, its
water tank should be filled up with water. It is carried out in the
following order:
џOpen completely the turn-cock for hot water of the most
distant mixing tap.
џOpen the stop valve on pos. 4 from Fig. 8.
џWait for the air from the system to come out and over half a
minute from the fitting outlet to flow out a thick and strong
water stream.
џClose the turn-cock for hot water of the mixing tap.
џlift the lever of the combined valve on pos. 5 from Fig. 8 and
wait for about 30-60 seconds until a thick and powerful
stream of water runs out from the valve side opening.
џLoose the lever of the combined valve.
WARNING! If no water is coming out of the opening of the
combined valve or the flow is weak (during normal water
pressure), this should be considered as a malfunction
indicating that impurities from the plumbing or caused by
sewage connections have blocked the safety valve of the
combined valve.
IT IS FORBIDDEN to proceed with appliance electric connection
before eliminating the reason for malfunction!
WARNING! Failure to comply with the requirements for
connection to the water supply system may cause partial filling
up of the water tank and malfunction of the heating element, or
when the combined valve is not installed at all or has been
improperly installed this may even cause destruction of the
water tank, the room and/or other damages to tangible and
intangible property. Such consequences are not within the
scope of manufacturer or seller warranty liabilities and shall be
at the expense of the party, which has not observed the present
manual instructions.
WARNING! The combined reciprocating safety valve is one of
the unit safety components ensuring security for water heater
users. It is specifically FORBIDDEN to use the water heater
with a defective or removed/unmounted combined safety valve!
The water heater connection to the water supply system must be
performed only by qualified persons.
Where necessary the safety valve may serve for draining the water
out of the water tank. It is carried out the following order:
џDisconnect the heater from the electrical power supply
network with the optional device and for greater security
disconnect the fuse in the heater phase circuit.
џCut the cold water access to the appliance - close the stop
cock, pos. 4 from Fig. 8.
џOpen the hot water cock on the tap or disconnect the tank hot
water pipe (outlet pipe) connection.
џLift the lever of the combined valve 5 in Fig. 8 and wait until
the water stops flowing out of the valve opening.
These steps do not still secure the complete draining of the water
out of the tank. It is completed only by a qualified person because it
requires complete disconnection of the appliance electric circuit
and dismantling the water tank flange.
WARNING! IT IS STRICTLY PROHIBITED to turn on the heater
power while the water tank is partially or completely emptied of
water! Do not forget to fill the tank with water before putting it
back into operation.
WARNING! The coolant circulation through the heat exchanger
of a water heater equipped with such device is PROHIBITED
when the water tank is partially or completely emptied of water.
WARNING! When draining the water out of the water tank all
necessary precautions must be taken to prevent damages from
flowing out water.
CONNECTING THE HEAT EXCHANGER OF
WATER HEATER TO THE ALTERNATIVE HEAT
SOURCE CIRCUIT
The water heater with heat exchanger must be connected to the
alternative heat source in accordance with the special additional
instructions provided by the company responsible for the
installation and connection of the heater design. It is mandatory to
install all supplied and/or recommended by this company safety,
control and coolant movement management devices.
WARNING! It is prohibited to fit stop valves on heat exchanger
both ends (inlet and outlet) simultaneously. In cases where the
water heater heat exchanger shall not be used and is not
connected to the heat source circuit, it must be filled with
propylene glycol solution suitable for heating systems.
Connecting the heat exchanger of the water heater to an
alternative heat source circuit must be completed only by qualified
technicians in the field from a company specializing in such
services and in accordance with the design.
WATER HEATER CONNECTION TO THE
POWER SUPPLY NETWORK
WARNING! Do not proceed to connect the water heater to the
power supply network unless you have made sure that its water
tank is full with water! Check!
The water heater is an appliance with protection degree against
current damages Class I, which requires its compulsory
connection to the earthling circuit of the power supply installation.
The water heaters models electric circuit schema are shown on
Fig. 10 and 11 (with two heaters, modifications with „D“)
The electric power supply of the water heater is 230 V~ and is
performed by a separate current circuit of insulated three-core
2
supply cable with a cross-section of each of the wires of 2,5 mm
(phase, neutral and grounding). Therefore if the in-wall cable is two-
wire, a qualified electrician must add a third, protective conductor
with no interruption on its track from the switchboard to the water
heater. If the earthling conductor/wire has intermediate
connections, latter must be secured against loosening. Otherwise
the appliance shall not be correctly earthed and it shall reduce its
safety.
WARNING! IT IS COMPULSORY that in the electric circuit
feeding the heater is installed such a device which in the
conditions of over voltage category III provides full
disconnection of all poles. The conductors between the circuit
and the device incoming electrical terminals must not be
interrupted by any circuit breaker or fuse. Should the water
heater be installed in premise with shower cubicle and/or bath
the disconnecting device must be located outside.
All the extremities of wires in the appliance circuit must be properly
connected to the main power switchboard and in the heater
connection point to the power supply grid. In the phase circuit it is

EN
11
obligatory to install an electric fuse 10 А for water heater electric
capacity up to 2 kW and 16 A for electric capacity of 3 kW. The
electric installation to which the heater will be connected must be
built in accordance with the requirements of the applicable statutes
and local regulations in force. Where the regulations in force do not
require that in the water heater circuit be installed an automatic
breaker against leakage of current (residual current protection
device), we recommend to install such a device.
The connection of the cables from the mains switchboard to the
unit terminals shall be carried out after carefully removing the
plastic cover so that the electrical wiring in the unit does not
disengage. In accordance with electric circuit schema glued on the
cover connect the phase conductor of the power wire to the
terminal marked L (or A1 depending on the version), the neutral
wire to the terminal marked N (or B1) and the earthling - to the
security terminal (screw or stud) marked for safety grounding. The
power cord must be secured against displacement by using the
cable clamp located next to the cable entry in the plastic cover.
After connecting and attaching the power cable, put the plastic
cover into place and secure it with screws, taking care for free
movement of cables, thermostat capillary tube and the control
switch.
If you have purchased water heater with pre-installed power cord
with a plug, the electric connection shall be carried out as the plug in
put directly in a functioning and grounded socket of the premise
electric installation. The socket should be on a separate, dedicated
only for the water heater circuit and located so as to be easily
accessible after the unit installation. The section of the electric
installation wires in which the socket is placed must be suitable for
the water heater electric power consumption. On the phase line
must be installed a fuse (10 A for a capacity of 2 kW and 16 A for 3
kW). The installation must be carried out in compliance with the
regulations in force. Taking out the power cord plug from its socket
shuts down the water heater. Faulty and / or inappropriate electric
installation and / or socket are high-risk conditions for accidents
with damages to the product and possible damages to the
environment, objects and living species.
Once the appliance is connected to the power supply grid check its
functionality.
WARNING! Failure to comply with the requirements concerning
connection to the mains shall impede the appliance safety, in
which it is prohibited to use. Adverse effects occurring as a result
of non-compliance with requirements concerning the appliance
electric connection are not covered by the manufacturer and
seller warranty liabilities and are at the expense of the party
violating the requirements of this instruction manual.
The water heater connection to the power supply and checks of its
functionality shall be performed only by specialists and are not
manufacturer or seller obligations and are not subject to warranty
service.
HOW TO USE THE APPLIANCE
The water heater is switched on operative mode by switching the
light key by pressing its extremity marked „І”. With the knob you
may adjust to desired water temperature. Lighting of the key when
in switched on position indicates that the water heater is operating
and water is heating, while when the light is off it indicates that the
water has reached adjusted temperature and the heater is
switched off. You may switch off the appliance by pressing the end
of the button of the glowing key marked "0". The water heater
complete disconnection from power supply takes place from the
additional disconnecting device.
For models marked with the letter "D" each key on the two-buttons
light key located on the control dashboard serves to switch on / off
one of the heaters. Thus you may use appliance half or full electric
power depending on the specific needs and desired time for water
heating.
The chart around the thermostat knob has a distinct sector marked
ECO. When the cursor of the knob is in the sector, the water
is warmed to an optimum temperature at which the heat losses of
the device are reduced and the reduced use of electric energy.
At the same time, the warm water is sufficient for normal
households. When a need for a large amount of mixed water is
required the thermostat knob is rotated in the direction of
travel counterclockwise to its maximum position, to reach the
higher temperature of the water in the tank. We recommend to
keep the knob in the sector ECO, when the heater is left on for
long periods without use of hot water and only to store heated
water.
The appliance built-in thermostat unit has antifreeze function.
When the thermostat knob is to the extreme left, at the scale
beginning, the heater shall switch on at ambient temperature
around 8-10°C and shall switch off at about 12-15°C. Thus in
case of air temperature fall in the room, the water in the tank
will be protected from freezing. ATTENTION! This feature
shall not prevent the water in the room plumbing from freezing!
Switching on and off, set up and using water heaters equipped
with electronic control board takes place in accordance
with the instructions and requirements listed in the
additional manual supplied with the appliance - instruction how to
connect and use an appliance with electronic control board. For
such appliances the additional instruction manual is an
integral part of the present installation and operation manual.
The temperature indicator installed on the appliance external
coating indicates the process of water heating. It is not a device for
control measurement and indicates only the approximate
temperature and quantity of hot water within the water tank.
WARNING! Do never switch the appliance if there is a chance
that the water in the water tank is frozen! This shall damage
both heater and the tank.
WARNING! This appliance may be used by children of age
over eight years old and persons with reduced physical,
sensory or mental capabilities, or lack of experience and
knowledge, where they are under supervision or instructed
about the safe use of the appliance and understand the
dangers. Children must not be allowed to play with the unit! It
is absolutely forbidden that children undertake cleaning or
servicing of this appliance!
Within the combined valve is built a special valve which during
water heater normal operation allows the expanded during heating
water not to leak through the valve side hole, but to pass into cold
water plumbing. The quantity of this water is negligible and usually
is with low temperature. During normal operation of the water
heater, as well as in present of additional return valve, it is possible
that through the valve side opening leak some water drops. This

EN
12
should not be perceived as defect and the side hole of combined
valve should not be blocked because it shall cause destruction of
the tank. The built-in non-return valve in the combined valve
prevents, in case of cutting water supply, the water in the water
tank to return to cold water pipeline.
Using the built-in heater exchangers (for appliances equipped
with) to heat the water in the tank must take place in accordance
with the instruction provided for by the persons who carried out the
design and installation of the system for heating water from
alternative electric sources. Compliance with the instruction in
such guides is mandatory.
When the appliance is used in areas with water rich in limestone it
is possible to hear some noises during water heating. The noise is
due to the limestone deposition on the heater and in the tank. The
quantity of limestone contained depends of the type of water and
its heating temperature. When the latter is higher than 60°С the
quantity of separate limestone increases. Accumulated limestone
impedes the heater efficiency and may even cause its failure, while
increasing the time for water heating.
When using the appliance it is possible to hear some weak noise
due to the water flow through the pipelines and the appliance, as
well as to the natural process of expanding and heating.
When the heater is regularly used to heat water to a lower
temperature, it is recommended to turn the thermostat knob at
least once monthly to its maximum position, then to heat the water
to maximum degrees and keep it such at least for 24 hours. The
purpose it to prevent bacteria growth.
ADDITIONAL CORROSION PROTECTION
Enameled water heater tanks. In each water heater with
enameled tank is installed additional corrosion protection. It
consists of an anode of special alloy operating only when the water
tank is full. The anode is a consumable (i.e. a device with normal
wear during the appliance operation) and its average operational
life is up to 3 (three) years. This period depends much of the type of
operating the appliance and the characteristics of the heated
water. After the period of operational life, a manufacturer
authorized specialist or dealer service company must check the
conditions of the anode. Where necessary it should be replaced
with new one. Compliance with the inspection deadline and timely
replacement of the anode is important for the effective protection
of the tank from corrosion. Both the assessment and replacement
of the anode are not subject of manufacturer and seller warranty
liabilities.
Water heater with enamel tank and anode tester. The
availability of the anode tester as control device is essential for the
heater operation. Some water heater modifications with traditional
thermostat are equipped with electromechanical anode tester
(Fig. 9). It consists of a arrow-indicating system with a scale and
switch (button). The scale has two sections - red and green. In tank
normal operating condition the tester pointer is in the red section -
the tester is not switched on and the anode is working properly.
Checking the anode efficiency is carried out when the water is fully
heated (switched off thermostat, i.e. the key is not lit) by pressing
for few seconds the button on the tester. The arrow shall depart in
the direction of the scale green sector. The magnitude of the
variation is strongly affected by the parameters of the water and its
temperature, as the boundary between the two sectors
correspond to the water average values. The anode efficiency
criterion is its arrow deflection. When at the time of pressing the
tester button, the arrow does not divert or is hold at the beginning
of the red section, you should contact the specialists at your
nearest manufacturer or vendor authorized service company.
Their specialist shall review the tank corrosion protection and
repair, if necessary. In some water heaters modifications the
electronic control board indicates the anode efficiency and degree
of wear with periodic regular display blinking. With advanced wear
the size of lighted part decreases. More specifically the process is
described in the additional instruction manual concerning the
electronic control board functions. Once the lighted part of the
display switches off completely you may contact the closest
service company to review and eventually replace the anode.
Water tanks of high quality chrome-nickel steel. Corrosion
protection and guaranteed long life are secured by correct choice of
steel, adequate design and engineering construction during tank
manufacture process.
SERVICE, PREVENTION, MAINTENANCE
In order to secure reliable operation of the water tank in areas with
highly calcareous water it is recommended to clean the limestone
accumulated within. This operation should take place at least once
every two years, while in areas with higher limestone content even
more frequently. The depositions on the enamel coating should not
be removed otherwise than wiped with dry cotton cloth and without
using hard tools. Regular limestone removal and cleaning is
particularly important for appliance reliable operation. It is
recommended that during this maintenance operation you carry out
a review of the enameled tank anode condition. These services are
not subject to warranty coverage and must be performed only by
qualified person.
WARNING! In order to ensure safe and trouble-free operation of
the water heater, the combined valve should be checked
regularly for reduction of its permeability. This is done by lifting
the lever, and wait for 30-60 seconds from the side opening the
valve to flow thick and strong jet of water. This operation must be
carried out after connecting the heater to the plumbing and when
filling of the tank with water, in the process of using the heater not
less than once every two weeks, as well as eventually after stop
and start of water supply. When at full tank by opening the valve
does not leak or water flow is weak, there is a failure and
probably the valve is clogged by impurities in the sewage. Using
water heater combined with a defective valve is strictly
prohibited. Switch off immediately the appliance from the power
supply and contact the nearest authorized by manufacturer
service company. Otherwise, it will cause damage to the water
tank, and could cause tangible and intangible damages in the
room where the water heater is located.
When you are not certain about the temperature in the room where
the water heater is installed, i.e. that it may fall below 0°C, the
water from the water tank MUST be drained - please refer to
section 'CONNECTION TO THE WATER SUPPLY NETWORK'
The water heater outer shell and plastic parts can be cleaned using
only a slightly damp soft cotton cloth and never with invasive and/or
abrasive substances and preparations. Before cleaning the
appliance, it MUST be disconnected from the power supply with the
additional disconnection device or by unplugging the plug on the
power cord. IT IS FORBIDDEN to clean the appliance with steam
generator. Particular attention should be paid to prevent wetting of
the appliance light switch on its control panel. The water heater may
be switched on in operation only after complete removal of

EN
13
moisture.
The rules for checking the corrosion protection and anode
replacement (please refer to previous section), as well as removal
of the accumulated limestone, must be strictly observed both during
and after the appliance warranty period.
During the appliance usage and maintenance do not damage the
metal plate with its technical data and serial number. Should you
take it off, keep it with the warranty form because it is the document
serving to identify the water heater.
FAILURES
When the heater does not heat the water, check if the external
disconnecting device is not switched off, if the lighting key is
switched off and if the thermostat knob is not turned to the lowest
position.
If the power supply is in order, the lighting key is switched on and
the thermostat knob is turned to its highest position, but the water
in the appliance is still not warming (it is possible that the lighting
key or the signal lamp are lighted or not), using the external
disconnecting device unplug the heater and contact the nearest
authorized service company.
In case when from the mixer at completely open tap for hot water
there is no leakage or water flow is weak, check if the filter at the
mixer outlet is not clogged, or whether the shut-off valve before the
heater is not fully or partially closed (4, Fig. 8), or if water supply is
not stopped. If all listed above causes are not the cause of failure,
using the external disconnecting device unplug the heater and
contact the nearest authorized service company.
When the water heater is equipped with electronic control board, at
the end of the additional instruction manual are listed the error
messages appearing on the display in case of failure and what
measures to take for each case. In any other general case of
failure, using the external disconnecting device unplug the heater
and contact the nearest authorized service company.
In case of failure of the power cord and/or plug for water heaters
with such, contact the nearest authorized by the manufacturer
service company as the cord with plug must be replaced by the
manufacturer, its service agent, or a person with similar
qualifications in order to avoid danger.
