TECHNICAL DESCRIPTION
The water heater is intended for use only for domestic purposes in
the household and is used to heat water from common water
supply network, which composition and features comply with the
specified values in water quality legislation, such as its chlorides
composition should be less than 250 mg/l and its electric
conductivity should be more than 100 µS/cm, while its pH within
the limits of 6.5-8 for the water heaters with enameled water tanks,
and electric conductivity less than 200 µS/cm for the water heaters
with chrome-nickel steel water tanks.
Water heaters are working with contained therein under pressure
water. Water heaters are equipped with combined return valve,
which prevents runtime water pressure to exceed exposure limits.
Water heaters are manufactured with corrosion protection of the
water container - steel with durable enamel coating and an
additional cathodic protection of anodes with special alloy. In
production are as well modifications with the anode status
indicator - anode tester ( "A").
The thermal insulation of the water container is of foamed
polyurethane.
Under pressure water heaters for mounting over the sink are
shown in Fig. 1, and those to be mounted under the sink - in Fig. 2.
The parameters of basic water heaters with enameled water tank
are recorded in the table.
INSTALLATION OF THE WATER HEATER ON THE
WALL OF THE PREMISES
The water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0°C. For water
heaters under pressure the availability of a siphon on the
installation for waste waters or another system of the same
purpose is needed, as during normal usage 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.
When choosing a place of installation the dimensions of the
device, its security from dripping water, method of attachment and
connection to water and electricity installations are taken into
account.
WARNING! The water heater is equipped with a power cord
with plug and can NOT be installed in a room for bathing!
In the water heater packaging is placed a suspension plate (Fig. 3)
and 3 pcs. screws and dowels for concrete. With two of the dowels
and screws fasten the hanging plate securely to the wall of the
room. The location of the plate is selected so as to provide
sufficient space for the device and the fittings thereof, and its water
and electrical connections. The wall must be of sound and dense
material (such as concrete). It is unacceptable for hanging the unit
on decorative walls or made of hollow material. Once the plate
suspension is mounted, then the tank is hung on it. For this
purpose on the device rear side there are provided holes. After the
suspension of the appliance using the third set dowel and screw fix
the unit rigidly to the wall through the opening of the ear of its hull,
located to the side of the cover with the management bodies - see
Figures 1- .2
WARNING! Failure to comply with these requirements may
result in damage to the device, other devices and the room in
which the appliance is installed. In these cases, such damages
are not covered by the warranty obligations of the manufacturer
and the seller.
CONNECTION OF THE WATER HEATER TO THE
WATER SUPPLY NETWORK
Connecting water heaters under pressure
With an arrow towards the pipe and blue color is marked the cold
water pipe and with an arrow from the pipe and red color insert - the
hot water pipe.
WARNING! IT IS MANDATORY in the cold water to the unit to
be mounted the supplied combined return valve and to keep the
arrow on the valve body indicating the direction of flow through
water flow.
IT IS PROHIBITED to mount any valve between the combined
valve and the water heater! It is absolutely forbidden to block
the side hole of the combined valve!
The connection of the water heater under pressure above sink is
carried out in accordance with Fig. 4.
The connection of the water heater under pressure under sink is
carried out in accordance with Fig. 5.
IT IS FORBIDDEN to install the combined valve in the space
above the unit!
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).
Filling the water tank of the unit under pressure is carried out in the
following sequence: open the shut-off valve in the cold water pipe;
open the shut-off valve of the hot water mixing battery; wait until
the water flow is strong and solid; close the tap and hot water; lift
the lever of the combined valve and wait 30-60 seconds of the
lateral opening of the valve to flow thick and strong jet of water;
then relax the valve lever.
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.
If necessary you may make a system for draining dripping water
from the combined valve side hole. The drain pipe must have
constant downward slope and located in anti-freezing
environment with extremities in the atmosphere.
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. 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! When draining the water out of the water tank all
necessary precautions must be taken to prevent damages from
flowing out water.
WARNING! IT IS ABSOLUTELY PROHIBITED TO SWITCH
ON POWER SUPPLY TO THE SYSTEM WHEN THE WATER
TANK IS PARTIALLY FILLED OR EMPTY OF ITS WATER
CONTENT! Do not forget to fill the tank with water before
putting it back into operation.
The water heater connection to the water supply system must be
performed only by qualified persons.
CONNECTION OF THE WATER HEATER TO THE
ELECTRIC 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 competed with a protection degree for
electrocution - Class I.
Connecting the water heater to the power supply 230 V ~ is carried
out rotating the knob for the unit temperature anti-clockwise until it
stops and the Illuminated key switches in OFF position (pressed
the end marked "0"), has joined the plug on power his cord to the
upright and properly connected with protective contact terminals
type F or E (Schucco, French type). The wires from the electrical
2
circuit of the contact should be with section 2,5 mm each, and fuse
in the phase line is 10 A. The socket must be positioned so that it is
easily accessible after installation of the water heater to the wall
and connecting it to the water installation. 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.
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. 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.
Only qualified persons are entitled to connect the water heater to
the mains and to check its functionality.
USAGE OF THE APPLIANCE
Your water heater is switched on in operating mode by pressing
the glowing key on its end marked "I" and rotating the knob for the
temperature clockwise. You may switch off the appliance by
pressing the end of the button of the glowing key marked "0".
Complete shutdown is done by subtracting the plug on the power
cord from the outlet.
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.
Using the knob the temperature to which it will heat the water may
be adjusted. 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!
Within the combined valve of the water heaters under pressure is
built a special controller 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 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 controller in the valve prevents, in case of cutting water
supply, the water in the water tank to return to cold water pipeline.
During the water warming in the water heaters with free outflow the
water expanded by temperature leaks from the fitting outlet. This is
not a defect! Do not try to stop the drip, as tightening the mixer
knobs - you can damage them!
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.
When the appliance is used in areas with soft water rich in limestone
it is possible to hear some noises during water heating. The noise is
due to the limestone stitching on the heater and contained within 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 in order
to prevent bacteria formation.

CORROSION PROTECTION, PREVENTION,
MAINTENANCE
Enameled water heater tanks
In each water heater with enameled tank is installed additional
corrosion protection. It consists of an anode protector (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
this period, 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.
Water heater with enamel tank and anode tester
The availability of this information device (Fig. 6) it is essential for
the operation of the heater. 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 (the thermostat is in position OFF, 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. They will review the corrosion protection and
repair it if necessary. The timely replacement of the anode protector
is a prerequisite for extending the life of the enameled water tank.
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! To ensure safe and trouble-free operation of
pressurized water heater must be checked if it is not reduced
permeability of its combined valve. 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.
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 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 plug of the cord can be plugged into the socket only
after complete removal of moisture.
The rules for checking the anode 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 power cord
plug is plugged, 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 plug from the power cord
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 weaker than normally, check
that the inlet mixer nozzle of the instruments with free flow is not
clogged, or 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
of Fig. 4-5), or if water supply is not stopped. If all listed above
causes are not the cause of failure, unplug the plug on the power
cord or using the external disconnecting device unplug the heater
and contact the nearest authorized service company.
Failure of the mixer of a water heater leak free and requires
replacement with a new one, it must be of the same type or of a
type approved by the manufacturer of the tank. It is imperative to
contact a competent specialist in this field, as we recommend it to
be representative of the manufacturer or its authorized service
company. The installation of improper and / or unapproved mixer is
a danger! It is forbidden to use the device with such a mixer!
In case of failure of the power cord and plug of 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.
