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
neutral wire to the terminal marked N (or B1) and the earthling – to
the security terminal (screw or stud) marked for protective
earthing. The power cord must be secured against displacement
by using the cable clamp located next to the cable hole 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.
Only qualified persons are entitled to connect the water heater to
the mains and to check its functionality.
HOW TO USE THE APPLIANCE
The water heater is switched on operative mode by switching the
rocker of the illuminated rocker switch by pressing its extremity
marked „І". With the knob you may adjust to desired water
temperature. Lighting of the rocker 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 rocker of the
illuminated switch 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 rocker on the double-
rocker illuminated switch 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.
Modifications with letters "G", "GN", "WG" and "WDG" in their
model numbers are not equipped with built-in switch. They are
included/excluded in/from operating mode using the external
device. In the plastic cover of these devices is mounted signal
lamp (LED) that shines while the electric heating element works.
Modifications with letter/s "W" in their number are equipped with
modification ), the
rocker switch without LED indication. It is located on the bottom of
the appliance, in the central part of the plastic cover and is used for
turning on/off the device to/from operation mode of the heating
element. The built-in LED indicator located above the hand wheel
of the thermostat indicates when the heating element is working.
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!
There is a sector marked ECO on the graphics around thermostat
knob. When the knob mark is in the ECO sector area the water is
heated to optimal temperature with redused thermal losses and
with lower electrical energy consumption. At the same time the
heated water is enough for domestic use. When greater volume of
mixed water is needed the thermostat knob should be set to
maximum setting for reaching higher temperature of the water in
the water heater. We recommend the knob to be set to ECO when
the water heater is being switched on for extended periods of time
with no warm water consumption only for storing the heated water.
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 thermometer installed on the appliance external coating
indicates the process of water heating. It is not a measurement
device 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
