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
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-installedpower 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
requirementsof this instructionmanual.
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 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
