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 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

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.

V. 

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.

•

Vertical installation GCV

 (fig. 1a, table 1)

 –

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). 

•

Horizontal installation GCH and GCR

 models (fig.1b, 1c) – At horizontal 

installation the distances between the carrying hooks are different with the 

different capacities and these values are indicated in table 2 - fig.1b and table 

3 - fig. 1c. 

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. 4:  

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 (fig 4) 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.

3.2. 

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 ( )

3.3. 

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
