RUST PROTECTION MAGNESIUM ANODE (FOR WATER
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!
VII.
OPERATION
1.
Switch on:
Before switching on the appliance for first time, make sure that the
water heater is properly connected to the power supply network and
full with water.
The appliance 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).

2.1.
Models with а built-in switch
•
There is an embossed marking on the button of the electrical switch
Push and release the button in order to switch on the electrical
switch. If it lightens, this means that it is switched on. The button lights
constantly unless the switch is switched off or the appliance power
supply from electrical main is switched off (see item 1 above). The light
•
indicators lighten too (see item 2.2. below).
In order to switch off the electrical switch, push and release
the button again. It must stop to light if it is switched off. The light
indicators stop lighting too.
2.2.
Light indicators
The indicators light in red color – means that the appliance is in heating
mode
The indicators light in blue color – means that water is warmed and the
thermostat is switched off, because the set temperature is reached
•
The light indicators do not light when:
•
The electrical switch of the appliance is switched off
•
The appliance power supply from electrical main is switched off
Protection according to the temperature is switched off – see item
3 below
2.3.
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. Turn the knob to the
upward indication, in order to increase the temperature of the hot
water.
Place the thermostat knob in position for maximum
temperature (unless it is on this position constantly), for period
of one day each month - see Annex I (11) Maximum temperature of the
thermostat. This ensures higher hygiene of the used hot water.
IMPORTANT: Models that do not have thermostat control
knobs have automatic water temperature preset by the
manufacturer - see Annex I (12) Default temperature settings.
ANTI-FREEZE MODE (fig.2). With this setup the device
maintains temperature that does not allow the water freeze in
it. The electrical supply of the appliance should be turned on and so
must be the appliance. The safety valve and the pipe between the valve
and the appliance must be protected from freezing. In case that for
some reason the electrical supply is cut off, there is a risk of freezing of
the water in the water tank. For this reason we recommend draining the
water out of the appliance before long absences (longer than a week).
e
Position
(Energy-save mode) – At this mode, water temperature
reaches up to approximately 60°С. Heat losses are reduced in this way.

3.
Protection according to the temperature (valid for all 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.
When this device operates, it does not self-reset and the
appliance will not work. Please call an authorized service for
solving the problem.
VIII.
MODELS EQUIPPED WITH A HEAT EXCHANGER (SERPENTINE TUBE).
These are appliances with inbuilt heat exchanger and are intended to
be connected to the heating system with maximum temperature of the
heat carrier of 80°C.
The control over the flow through the heat exchanger is a matter of
solution for the particular installation, whereby the choice should
be made at its design (e.g. external thermostat that measures the
temperature in the water tank and operates a circulation pump or a
magnet valve).
Water heaters with a heat exchanger provide the opportunity for the
water to be heated in two ways:
1.
by means of a heat exchanger (coil) – a primary way of heating the water,
2.
by means of an auxiliary electrical heating element with automatic
operation, built in the appliance – it is used only when additional
heating of the water is needed or in case of repairs to the system of the
heat exchanger (coil). The proper way of connecting the appliance to
the electric network and how to work with it has been specified in the
previous paragraphs.
Mounting:
In addition to the mounting manner outlined above, especially for
the latter models, it shall be required to connect the heat exchanger
to the heating installation. The connections are to be carried out in
.
observance of the direction indicated by the arrows on Fig. 1d÷Fig. 1f.
Technical parameters (table 5):
Surface of serpentine [m²] - S;
Volume of serpentine [l] - V;
Operational pressure of serpentine [MPa] - P;
Maximum temperature of heat carrier [°C] - Tmax.
We recommend you mount stopcocks at the heat exchanger' s entry
and exit points. By stopping the flow of the thermophore via the lower
(stopcock) you shall avoid the unnecessary circulation of the thermophore
during periods of use only of the electric heating element.
Upon disassembly of you water heater equipped with a heat exchanger
you must close both stopcocks.
There is a connexion with internal thread of ½" welded to the water
tank for the purposes of installing thermal probe – marked with „TS".
The appliance is fitted with brass pocket for a thermal probe which
should be screwed into the aforesaid connexion.
The usage of dielectric bushings for connecting the heat
exchanger to an installation of copper pipes is obligatory.
For ensuring minimal corrosion, pipes with a limited diffusion
of gasses must be used in the installation.
IX.
PERIODIC MAINTENANCE
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 ''deceptive" 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).
