see page 33, replace if necessary.
Check amount of regeneration air (270 -
300 l/h), replace double non-return
valve (
39
) if necessary, see page 41.
Check hose, replace diffusor if neces-
sary.
Check cycle time, see page 31.
Watch relay KY1 u. KY2, check wiring
and plugs of solenoid valves.
Replace solenoid valves
Red signal-LED „
Fault / Fel“
(
20
) on
the instrument panel (
2
