class I and must be connected to the protective earth
conductor.
The unit must be durably connected to permanently
I
installed lines.
I In order to meet the current safety requirements, an
all-pole disconnecting device must be present on the
installation side. The contact gap must be at least 3 mm.
I The continuous-flow heater is suitable for enclosed
(pressurized) operation only.
I The tap fittings must be permitted for operation with

I
must be disconnected from the mains voltage and
the water supply cut off!
Only connect the electric supply after the water
I
supply.
