English

•

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

•

conductor with yellow-green insulation – to the safety conductor of the

wiring ⏚

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 ⏚ .

ATTENTION! The power supply conductor insulation from xed wiring

must be protected from direct contact with the ange (in zone under

the plastic panel). For example, insulating sleeving having temperature rating

higher than 90 °C can be used.

After the installation, put the plastic cover back in its place!

VI. 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 qualied 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 rst 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).

2. Water heaters with electromechanical control

Fig. 2 where:

1 - Moisture-proof button for heater switching (for models with a switch)

2 - Light indicator

3 - Regulator handle (only for models with adjustable thermostat)

When there is in-built in switch in the water heater, you must switch it on

Electrical switch with one knob:

0 – switched o;

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

o󰀨 when the specied by the thermostat water temperature level is reached.

Electrical switch with two knobs:

0 - switched o; I; II - switched on;

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-o󰀨 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 o󰀨 (see 3 below).

For models without a switch

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

o󰀨 when the specied by the thermostat water temperature level is reached.

It does not lit on when there is not supply voltage or the thermal cut-out

(temperature protection) is switched o󰀨 (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.

Position e (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.

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 o󰀨 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.

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 ow 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 specied 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. 1е.

Technical parameters (table 6):

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 ow 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 tted 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 diusion of

gasses must be used in the installation.

IX. PERIODIC MAINTENANCE

In the conditions of normal use of the water heater, under the inuence of high

temperature, limestone (the so-called lime scale) deposits on the surface of the

heating element. This worsens the heat exchange between the heating element

and the water. The temperature on the surface of the heating element and around

it increases. Specic noise can be heard – of boiling water. The thermoregulator

begins to switch on and o󰀨 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 centre or service facility, this service remaining at the customer’s expense.

This preventive maintenance should include cleaning and examination of the

anode protector (for water heaters with glass-ceramic coating), which has to be

replaced with a new one, if necessary.

To clean the appliance, use a damp cloth. Do not use abrasive or solvent-

containing detergents.

The manufacturer does not bear responsibility for any consequences

arising from non-adherence to these instructions.

Instructions for protection of the environment

ld electric appliances contain valuable materials and must not be

disposed of with the domestic waste! Please contribute actively for

the protection of the resources and the environment and dispose of

the appliance in the buy-back

centres organized for this purpose

(if such are available).
