DESCRIPTION AND PRINCIPLE OF OPERATION

The appliance consists of a body, flange, plastic control panel, safety 

return valve.

1. 

The body consists of a steel reservoir (water tank) and  plastic 

housing (outer shell) with thermal insulation placed in-between, 

and two pipes with thread G ½“, for cold water supply (marked 

with a blue ring) and hot water discharge (marked with a red ring). 

The inner reservoir is made of steel proved against corrosion by a 

special glass-ceramic coating.

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 of cold water supply interruption. The 

valve protects the appliance from pressure increases higher than 

the allowed value during heating (! pressure will increase when 

temperature increases), by releasing the excess pressure through 

the drain outlet. Water dropping out through the drains during 

the warming process is a normal event that must be taken into 

consideration when the boiler is installed.

ATTENTION! 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. 

INSTALLATION AND SWITCH 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.

1. 

Installation

We recommend installation of the device at close proximity to locations where 

hot water is used, in order to reduce heat losses during water transportation. 

The selected location must exclude the possibility of water spray originating 

from the showerhead or other water contacts.

•

Appliances designed for installation 

above sinks

 are assembled in such a 

manner that the outlet/inlet pipes are pointed downwards (to the floor of the 

premise).

The appliance is affixed to a wall by means of mounting brackets attached to 

the unit's body. Two hooks are used to fix the appliance (min. Ø 4 mm) firmly 

on the wall (included in the mounting set). 

•

Appliances designed for installation 

under sinks

 are assembled in such 

a manner that the outlet/inlet pipes are pointed upwards (to the ceiling of the 

premise).

The appliances can be placed standing on the floor or mounted on the wall.
In case you want to mount the appliance on the wall, the suspension must be 

done with two hooks (

min. Ø 4 mm

) securely attached to the wall.

IMPORTANT: The type of appliance designed to be installed UNDER / 

ABOVE a sink is marked on the appliance. 

The bearing plank construction for boilers installed above / under sinks is 

universal and allows the space between hooks to vary between 96 and 

114mm. (fig.2). 

For clear understanding of wall installation schemes, please refer to fig.2 (A  

above sink, B under sink and C for floor installation).

ATTENTION! In order to prevent injury to user and third persons in the 

event of faults in the hot water supply system, the appliance must be 

mounted in premises outfitted with floor hydro insulation and sewer drainage. 

Don't place objects, which are not waterproof under the appliance under any 

circumstances. In the event of mounting the appliance in premises without floor 

hydro insulation, a protective tank with a sewer discharge drainage must be 

placed under the appliance. 

Notice: the set does not include a protective tub and the user 

must select the same.

Where: 1 – input pipe, 2 – safety valve (0.8 MPa), 3 – reduction 

valve (if the water supply pressure exceeds 0,6 MPa), 4 – stop 

valve, 5 – bell-mouth discharge to the sewer, 6 – hose; 7 - Drain 

water tap.
Upon connecting the water heater to the water supply system, take 

care of the indicative color markings /rings/ of the pipes:  

BLUE

 -  for cold /in-flowing/ water,  

RED

 -  for hot /out-flowig/ water.

The mounting of the safety return-valve supplied with the water 

heater is obligatory. The safety return-valve must be installed on the 

cold water supply pipe, according to the arrow stamped on its body 

that indicates the supplied water direction.  

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

.

ATTENTION! Other type of stopping armature is not allowed between 

the protection return valve (the protective device) and the appliance.

ATTENTION! Any other /old/ safety return-valves may lead to a failure of 

your appliance, therefore they must be removed. 

ATTENTION! Fixing the safety return-valve to threads longer than 10 

mm is not allowed, as it could damaged the valve and could make the 

use of your appliance dangerous. 

ATTENTION! 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.

The boiler is filled with water by opening the tap on the cold water 

supply system and the tap on the hot water mixing faucet. After the 

filling process is complete, a constant stream of water should flow 

from the water-mixing faucet. Now you can shut the hot water tap 

on the mixing faucet.
When you must empty the water heater, you should first cut it off 

the power supply. 

Draining procedure for boilers designed to be installed ABOVE 

SINKS: 

1. 

First shut the cold water supply valve  

2. 

Open the hot water valve on the mixing-faucet 

3. 

The water tap 7 (

fig 4a

) 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

IMPORTANT: When draining the boiler, take measures to 

prevent damages caused by the flowing water.

Draining procedure for boilers designed to be installed UNDER 

SINKS: 

1. 

Switch the boiler off the power supply network.

2. 

Dismantle the connecting water fittings from the boiler.

3. 

Disassemble the boiler from its installation place, turn it so the 

pipes point to the floor and pour the water in a vessel you have 

prepared for the purpose. Wait until all the water drains out of the
