Water heaters without power cord

The appliance has to be connected to a separate current loop of the 

stationary electrical installation, provided with a safety fuse with 

nominal current of 16A (20A for power > 3700W). Connection is done 

using copper single core (rigid) conductors – cable 3 x 2.5 mm² for a 

total power of 3000W (cable 3 x 4.0 mm² for power > 3700W).

In the electrical circuit providing power supply for the appliance there 

has to an inbuilt device which would disconnect all poles in case of 

category III overvoltage.

To install the power supply wire to the water heater, remove the plastic 

cover (Fig.2a). 

Connect the power supply wire in compliance with the marking on the 

terminals, as it follows:

 •

the phase – to marking A or A1, L or L1;

 •

the neutral – to marking N (B or B1 or N1)

 •

The safety wire must be connected to the screw joint marked with 

⏚.

After installation, put the plastic cover back in its place!

ANTI-CORROSION PROTECTION – MAGNESIUM ANODE

The magnesium anode provides additional protection to the water tank’s 

inner surface from corrosion. It is an element undergoing wear and tear 

and is subject to periodic replacement, which is at the expense of the 

user. In view of the long-term and accident-free use of your water heater, 

the manufacturer recommends periodic 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 centres or a 

qualified technician!

VI. 

OPERATION

This unit has four main operating modes: "Stand by", "Heating" - to 

maintain the set temperature, "Smart Control" - continuous self-

learning mode with automatic selection of the heating temperature 

regardless of the active operating mode and “Smart Home" - for remote 

monitoring and control.
Additional benefits are the signal emitted when buttons are pressed, 

the anti-freeze protection of the water heater, the " Anti-Legionella" 

function.
