Positioning of combs
After cleaning the recovery unit make sure the combs are positioned correctly, as shown
in fig. 36. Tighten the nuts on the compressor disk "A" respecting the torque setting of
0.6 Nm. If a torque wrench is unavailable, check that there is a fume passage of 1 mm
between the coils.

4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore
operation, press the RESET button (detail 8 - fig. 1) for 1 second or use the RESET on
the remote timer control (optional) if installed; if the boiler does not restart it is necessary
to eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter "F") which are automat-
ically reset as soon as the value returns within the boiler's normal working range.
Some faults linked to the circulating pump are signalled by the LED located around the
speed selector (fig. 37).
