IV. DESCRIPTION AND PRINCIPLE OF WORK

The appliance consists of a body, flange at the bottom side /for water heaters intended for vertical mounting/ or at the sides /for water heaters intended for horizontal mounting/, protective plastic panel safety-return valve.

1. The body consists of a steel reservoir (water tank) and housing (outer shell) with thermal insulation placed in-between made of ecologically clean high density polyurethane foam, and two pipes with thread G 12 " for cold water supply (marked by a blue ring) and hot water outlet pipe (marked by a red ring).

The inner tank may be of two types depending on the model:

- Made of steel protected form corrosion by a special glass-ceramics coating

• Made of stainless steel

The vertical water heaters may be outfitted with a built in heat exchange unit (boiler tube). The boiler tube's entrance and exit are located at the sides and represent pipes with thread G 34 ".

1. The flange is outfitted with: electric heater and thermostat. The water heaters with glass-ceramics coating are outfitted with a magnesium protector.

The electric heater is used for heating the water in the tank and is managed by the thermostat, which automatically maintains the set temperature. The thermostat has a built in overheating safety device, which switches of power to the heater when the water temperature reaches excessive values.

1. The safety-return valve prevents the appliance's complete emptying in the event the cold water supply is interrupted. The valve protects the appliance from pressure increases higher than the allowed value during heating (pressure increases upon an increase of temperature), via release of excess pressure during the drainage opening.

The safety-return valve cannot protect the appliance in the event of water mains pressure in excess of the able pressure stated for the appliance.

V. MOUNTING AND SWITCHING ON

Attention! Improper installation and connection of the appliance may make it hazardous for the health of consumers. It may cause grievous and comment consequences, including but not limited to all injuries and/or death. Improper installation and section of the appliance may also lead to damage to the owners' property /damage and/ or destruction/, or to third persons, as a result of, but not limited to g, explosion and/or fire.

Installation, connection to the main water and power supply, and putting into operation must be carried out by certified electricians and technical personnel certified in installation of this category of appliances, who have obtained their license in the state where the installation and commissioning of the appliance are carried out, and in compliance with its local legislation.

1. Mounting

We recommend the mounting of the device at close proximity to locations where hot water is used, in order to reduce heat losses during transportation. In the event the device is mounted in a bathroom, the selected location must exclude the possibility of water spray contact from the showerhead or portable showerhead attachment.

The appliance is affixed to a wall via the mounting brackets attached to the unit's body (if the brackets are not attached to the unit's body, they must be affixed in place via the provided bolts). Two hooks are used for suspending the appliance (min. ∅ 10 mm) set firmly in the wall (not included in the mounting set). The mounting bracket's construction designed for water heaters intended for vertical mounting is universal and allows a distance between the hooks of 220 to 310 mm (fig. 1a). For water heaters intended for horizontal mounting, the distances between the hooks vary for the different models and are specified in the table 1 to Fig. 1b.

In order to prevent injury to user and third persons in the event of faults in the system for providing hot the appliance must be mounted in premises outfitted for hydro insulation and plumbing drainage. Don't objects, which are not waterproof under the appliance any circumstances. In the event of mounting the fence in premises not outfitted with floor hydro tion, a protective tub with a plumbing drainage must be red under the appliance.

Notice: the set does not include a protective tub and the user must select the same.

2. Water heater connection to the pipe network

Fig. 4: a) - for vertical; b) - for horizontal installation

Where: 1 - Inlet pipe; 2 - Safety valve; 3 - reducing valve (for water main pressure > 0,6 MPa); 4 - Stop valve; 5 - Funnel connected to the sewer network; 6 - Hose; 7 - Drain water tap

Upon connecting the water heater to the water mains you must consider the indicative color markings /rings/ affixed to the pipes: blue for cold / incoming/ water, red for hot / outgoing/ water.

The mounting of the safety return-valve supplied with the water heater is obligatory. The safety return-valve must be mounted on the cold water supply pipe, in observance of the direction arrow stamped on its body, indicating the incoming water's direction. Additional stopcocks must not be mounted between the safety return-valve and the water heater.

Exception: If the local regulations (norms) require the usage of another protection valve or mechanism (in accordance with EN 1487 or EN 1489), then it must be bought additionally. For mechanisms operating in accordance with EN 1487 the announced operational pressure must be no more than 0.7 MPa. For other protection valves, the pressure at which they are calibrated must be 0.1 MPa lower than the one marked on the appliance's sign. In these cases the safety valve which the appliance is supplied with should not be used.

The presence of other /old/ safety return-valves may lead to a breakdown of your appliance and they must be d.

Other type of stopping armature is not allowed between the protection return valve (the protective device) and the ce.

The attaching of the safety return-valve to threads longer than 10 mm is not allowed, otherwise this may damage re and poses danger for your appliance.

With boilers for vertical assembly, the safety valve has to be connected to the ingoing pipe with the safety plastic of the appliance being taken o . After it has been led it should be in position as shown on Fig. 2.

The safety valve and the pipe between the valve and the water heater must be protected from freezing. During training - its free end must be always open to the here (not to be immersed). Make sure that the hose is also fed from freezing.

Opening the cold-water stopcock of the water supply piping network and opening the hot-water stopcock of the water-mixing faucet carries out the filling of the water heater with water. After the filling is complete, a constant stream of water must begin to flow from the water-mixing faucet. Now you can close the hot water stopcock.

In the event you must empty the water heater, first you must cut off its power supply. The inflow of water from the water mains must first be terminated and the hot water tap of the mixing-faucet must be opened. The water tap 7 (fig 4a and 4 b) must be opened to drain the water from water tank. If there is no such tap build in the pipe line, than the water can be drain as follow:

• Models equipped with safety valve with lever - You can drain the water from the water heater by lifting the safety return-valve's lever. Water will drain from the safety return-valve's drainage opening
• Models equipped with safety valve without lever - water can be drain directly from inlet pipe of water tank after when you disconnect it from water main.

In the event of removing the flange, the discharge of several liters of water, which remain in the water tank, is normal.

Measures must be undertaken to prevent damage from discharging water during draining.

In case that the pressure in the water mains is over the value pointed out in the above paragraph I, then it is necessary to assemble a pressure reduce valve, otherwise the water heater would not function properly. The Manufacturer does not assume any liability for problems arising out of the appliance's improper use.

3. Water heater connection to the electrical network.

Make sure the appliance is full of water prior to switching on the electrical mains power.

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.

The wall-plug must be properly connected to a separate electrical circle that is provided with a protector. It must be shed.

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 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).

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 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 shows:

1 - Thermal regulator
2 - Power switch
3 - Indicator lights
4 - Anode tester

Thermal regulator (1) and indicator light for „heating up / ready to use“

Setting of the temperature is provided by a knob for the thermal regulator (1). This setting allows for gradual adjustment to the desired temperature.

Fig.2 displays the rotation direction of the knobs.

e ENERGY SAVING – in this mode the water in the appliance is at a temperature of approximately 60^ C. Thus thermal loss is reduced.

Indicator light "heating up / ready to use" - indicates the status/operation mode of the appliance: the light is red while the water is heated and it is blue when the water has reached the temperature as set by the thermostat. The light is off when the power switch is in off position.

Power switch (2) and indicator lights

Single-level power switch:

0 - power is off;

I – power is on;

The power indicator light for I is on when the switch is turned on at level I.

Power switch with two levels:

0 - power is off;

I, II – power is on;

Selection of levels of heating power:

Rated power(as marked on the name-plate of the appliance )	Switched to level (I)	Switched to level (II)
1200 W 600 W 1200 W
1600 W 800 W 1600 W
2400 W 1200 W 2400 W

At level I of the switch, the power indicator light I is on.

At level II of the switch both power indicator lights I and II are on.

Anode tester (4)-(with models, having an integrated tester).

This facility serves for the identification of the current state of magnesium anode and indicates the need for its replacement. The anode tester is secured with button 4 and light indication 5 next to it (Fig.2). The state of the anode protector can be controlled by pressing button 4 (y)

When the illuminating indicator, besides it is lit in a blinking GREEN color, this means that the ANODE PROTECTOR functions in a normal, usual mode and protects your appliance from corrosion. When the illuminating indicator is lit with a blinking RED color, this means that the ANODE PROTECTOR is worn out and should be replaced.

The changing of the anode protector is done by a qualified technician.

The anode tester is able to read correctly the state of the anode protector only when the temperature of the water tank is higher 60°C. For this reason, before pushing button ), make sure that the water in the tank is heated enough at no quantity has been drained out of it with cold water been poured into it before that. The thermostat should go to the maximum temperature.

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 in the problem.

VIII. MODELS EQUIPPED WITH A HEAT EXCHANGER (SERPENTINE TUBE) - FIG.1B, FIG.1C, FIG.1D AND TABLES 1, 2 AND 3

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. 1b, 1c, 1d. 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.

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.

Models with a single heat exchanger and a thermal sensor pocket

Appliance installation is responsibility of the customer hence a qualified installation technician has to perform it

in accordance with the main user guide and the present appendix thereto.

Maximum temperature of heat carrier ( ^ )	80	80	80

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).
