3.1.
Models with power cord with a plug are connected by
inserting the plug into a contact. They are switched off the power
supply by drawing the plug out of the contact.
Attention! The wall-plug must be properly connected
to a separate electrical circle that is provided with a
protector. It must be earthed.
Water heaters fitted with a supply cord without a plug.
The appliance has to be connected to a separate electricity circuit of
the stationary electrical wiring.The connecting has to be constant-
with no plug contacts. The circuit has to be supplied with a safety
fuse (16A) and with inbuilt device to ensure disconnection of all
pole pieces in the conditions of over-voltage from category III.
The connecting of the conductors of the supply cord of the
•
appliance has to be carried out as follows:
conductor with brown insulation – to the phase conductor of

the electrical wiring (L)
conductor with blue insulation- to the neutral conductor of the

3.2.
Models without power cord
The appliance has to be connected to a separate electricity circuit of
the stationary electrical wiring. The circuit has to be supplied with a
safety fuse 16A (20A for power > 3700W). Copper single core (rigid
– non stranded) conductor shall be used for the connection – cable
3 x 2.5mm² (cable 3 x 2.5mm² for power > 3700W).
The electrical circuit supplying the appliance must have an in-built
device ensuring the splitting of all terminal poles under conditions
of super-voltage of category III.
To install the power supply wire to the boiler, remove the plastic
cover (Fig.2).
Connect the power wires in compliance with the marks on the
terminals, as follows:
•
•
the phase - to mark A, A1, L or L1;
•
the neutral - to N (B or B1 or N1)
The safety wire must be obligatory connected to the screw joint
marked with
.
After the installation, put the plastic cover back in its place!

RUST PROTECTION MAGNESIUM ANODE (FOR WATER
VI.
HEATERS WITH WATER TANKS COVERED BY GLASS-CERAMICS
COATING)
The magnesium anode protects the water tank's inner surface from
corrosion.
The anode element is an element undergoing wear and tear and is
subject to periodic replacement.
In view of the long-term and accident free use of your water
heater, the manufacturer recommends periodic inspections of
the magnesium anode's condition by a qualified technician and
replacement whenever required, and this could be performed
during the appliance's technical preventive maintenance. For
replacements, please contact the authorized service stations!
OPERATION.
VII.
Switch on.
1.
Before switching on the appliance for first time, make sure that
the boiler is properly connected to the power supply network and
full with water.
The boiler is switched on by a switch integrated into the
installation, described in item 3.2 of Section V, or upon connecting
the plug to the electrical contact (in the case of an extension cable
with plug).

When there is in-built in switch in the water heater, you must
switch it on.
Electrical switch with one knob:
0 – switched off;
I – switched on;
The knob lit when the switch is on.
The control lamp on the panel indicates the state (the mode) in
which the appliance is placed: it is lit when the water is being
heated and is switched off when the specified by the thermostat
water temperature level is reached.
Electrical switch with two knobs:
0 - switched off; I; II - switched on;
Choosing of different power levels of heating:
Rated power (marked on
the rating label)
1600 W
2000 W
2400 W
The buttons of the switch lit on, if they are switched on and during
heating. They stops to lit when the preset temperature of the water
is reached and the thermostat switch-off the voltage supply.
The control lamp lit on when there is supply voltage from electrical
main. It does not lit on when there is not supply voltage or the
thermal cut-out (temperature protection) is switched off (see 3
•
below)
Temperature setup (for models with adjustable thermostat).
This setup allows the gradual setting of the desired temperature, achieved
by using a handle on the control panel.
e
Position
(Energy-save mode) – At this mode, water temperature
reaches up to approximately 60°С. Heat losses are reduced in this
way.
Fig. 2a indicates the direction of rotation of the knob for the other
models with externally adjustable thermostat.
Attention! Place the thermostat knob in position for
maximum temperature (unless it is on this position
constantly), for period of one day each month. This ensures
higher hygiene of the used hot water.
Protection according to the temperature (valid for all
3.
models).
The appliance is equipped with a special facility (thermal circuit-
breaker) for protection against over-heating of the water, which
is switching off the heater from the electricity network, when the
temperature reaches too high values.
Attention! When this device operates, it does not
self-reset and the appliance will not work. Please call
an authorized service for solving the problem.
PERIODIC MAINTENANCE
VIII.
Under normal use of the heater, under the influence of high temperature,
lime scale /the so-called lime scale layer/ is deposited upon the heating
element' s surface. This worsens the heat exchange between the heating
element and water. The heating element' s surface temperature increases
along /of boiling water/. The thermoregulator begins to switch on and
off more frequently. A '' d eceptive" activation of the thermal protection is
possible. Due to these facts, the manufacturer recommends preventive
maintenance of your water heater every two years by an authorized
service center or service base. This protective maintenance must include
cleaning and inspection of the anode protector (for water heaters with
glass-ceramic coating), which shall be replace with a new one if need arises.
In order to clean the appliances use a damp cloth. Do not clean with
abrasive or solvent content detergents. Do not pour water over the
appliance.
The manufacturer does not bare the responsibility for all
consequences caused by not obeying the instructions, given
hereby.
Instructions for protecting the environment
Old electric appliances contain precious materials and thus
should not be thrown together with the household litter. We
kindly ask you make your active contribution for protecting the
resources and the environment by handing over the appliance
in the authorized buy-back stations (if such exist).
