Installation
1. Hang the boiler up in a vertical position on
fixing screws with the inlet and outlet pipes
to the bottom, maintaining clearances from
the walls and the ceiling.
2. Connect the boiler to the central heating
system equipped with a cut-off valves.
3. Fill the central heating system with a treated
water that substantially extends the life of the
heating elements.
4. Vent the central heating system.
5. Connect a boiler to the electrical system.
6. Fix the room thermostat, in accordance with
manual instruction.
7. Connect the room thermostat (by using two
wires 2 x 0,35 mm
2
) to the terminal of control
panel (RP entry).
8. Once you have finished the above procedures,
you can start the boiler. See the „Start-up” section.
While applying thermostat make sure there is no voltage on its entry!
Do not connect any voltage into RP, NA, WZ entries! This can result in perma-
nent controller damage.

Connection to the three-phase electrical system.
PNL - points of neutral and protective conductor
connection
PF - points of phase conductors connection
[1] - temperature limiter
Connection to the single phase electrical system
(for boilers of 4kW,6kW and 8kW)
PNL - connection points of neutral, protective and
phase conductors
[1] - temperature limiter
[2] - additional conductors (for single phase
system only)
Important: 4, 6 and 8kW boilers are factory preset to work as single phase boilers.
If you intend to connect the boiler to a three-phase system, take off the [2] wire set.
