the motor for the furnace head
is in an inappropriate position
(provided that the ‘close furnace
head’ key is not defective):
Situation A

on before the furnace head (1) is
mounted (initial start-up or after
maintenance of the furnace
head):
Press STOP to acknowledge the
error message. After that, press
the ‘close furnace head’ key.
Secure the furnace

the furnace head (1) is correctly
mounted.

key. If Err 22 reappears, press

the error occurring immediately
after switching on the furnace,
i.e. during the self-diagnosis.
Same as situation B.

to be switched off and on again
at the end of the procedure to
make sure that the self-diagnosis
is repeated.
