DESCRIPTION AND PRINCIPLE OF OPERATION

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, 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 fitted with electric heater and magnesium 

anode protector. The flange is fixed to the water tank with 

bolts.
The electric heater heats the water in the tank and is 

controlled by the thermostat, which automatically maintains 

the preset temperature.
The plastic control panel incorporates: switch (depending on 

model), adjustable thermostat (depending on model), and 

thermal cut-out and control lamps.
The thermal cut-out is a  device, which switches the heater 

off the power supply when the water temperature reaches 

excessive values. If this device is actuated, you should call a 

service station.
The signal lamps (depending on model) on the control panel 

indicate the current mode of the unit.
The magnesium protector provides additional anti-corrosion 

protection to the internal tank for heaters fitted with glass-

ceramic coating. 

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).
