Water heaters without power cord
EN
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!

T
he 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!
