Residual current circuit breaker (E)
When the installation is protected by means of
a residual current circuit breaker, which trips
when the appliance is connected, this may be
due to moisture in the heating element. When
an appliance containing a heater element has
not been used for a long period or stored in
a damp environment, moisture can enter the
element.
This should not be seen as a fault, but is
e
e nne n e
n e
the main supply via a socket without a safety
cut-out so that the moisture can be eliminated
from the element. The drying time can vary
from a few hours to a few days. As a preventive
measure, the unit should occasionally be run
for a short time when it is not being used for
extended periods of time.
Packaging
Packaging materials are chosen with
consideration to the environment and are
therefore recyclable.

• Functions and settings of the FC control
system, see the FC manual.
For units with electrical heating, also check the
following:
• Power supply to electric heater coil; check

2. Mark and disconnect the cables to the PC
board.
3. Unhatch the board from its PCB snap-in
