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
