DESCRIPTION AND PRINCIPLE OF WORK

The appliance is designed to operate in regions where the water hardness is not 

more than 10°dH. In case that it is installed in a region where the water is harder it is 

possible that limestone precipitation accumulate very fast. This can cause a specific 

noise during heating, as well as fast damaging of the electrical part. For regions 

with harder water yearly cleaning of the limestone precipitation in the appliance is 

recommended, as well as usage of not more than 2 kW of heating power.

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 ½ ‘’ 

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 (serpentine tube). The heat exchenger’s entrance and exit are 

located at the sides and represent pipes with thread G ¾ ‘’. 

2. 

  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. 

3. 

  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 acceptable pressure stated 

for the appliance.

IV. 

MOUNTING AND SWITCHING ON

Attention! Improper installation and connection of the appliance may 

make it hazardous for the health and life of consumers. It may 

cause grievous and permanent consequences, including but not limited to 

physical injuries and/or death. Improper installation and connection of the 

appliance may also lead to damage to the consumers’ property /damage 

and/ or destruction/, or to that of third persons, as a result of, but not limited 

to flooding, 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.

Notice

: The installation of the unit is at the buyer’s expense.

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. Ø 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, 1b, 

1c). For water heaters intended for horizontal mounting, the distances 

between the hooks vary for the different models and are specified 

in the tabl. 6 and 7 to Fig. 1d, 1e. For water heaters intended for floor 

installation - tabl.6,7 2 to Fig. 1h, 1g.

In order to prevent injury to user and third persons in the event of 

faults in the system for providing hot water, the appliance must be 

mounted in premises outfitted with floor hydro insulation and plumbing 

drainage. Don’t place objects, which are not waterproof under the appliance 

under any circumstances. In the event of mounting the appliance in 

premises not outfitted with floor hydro insulation, a protective tub with a 

plumbing drainage must be placed 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. 3:  

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 removed.

Other type of stopping armature is not allowed between the protection 

return valve (the protective device) and the appliance.

The attaching of the safety return-valve to threads longer than 10 mm is not 

allowed, otherwise this may damage the valve and poses danger for your 

appliance.

With appliances for vertical assembly, the safety valve has to be 

connected to the ingoing pipe with the safety plastic panel of the 

appliance being taken off. 

The safety valve and the pipe between the valve and the water heater 

must be protected from freezing. During hose draining - its free end must 

be always open to the atmosphere (not to be immersed). Make sure that the hose 

is also protected 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 (fig3) 

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 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 earthed.
