HOW TO USE THEAPPLIANCE
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.
In the horizontal water heaters are mounted two heaters with
capacity of 1.2 and 2 kW, which are controlled by the respective
keys of the switch. The heater 2 kW is used for fast receiving of
quantity of hot water. In order to heat the whole amount of water we
recommend you to use both of the heaters or this with 1.2 W
capacity. Through the knob you may adjust the desired water
temperature. The light of the switch being on indicates that the
water in the water heater is being heated, and turning off
–
the
water has reached the temperature set and the heater is off.
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
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 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.
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 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. 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 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 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. 7). 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
