Renew muffl ers
The dryer is equipped with a muffl er. If the muffl er becomes blocked, a dam pressure is gen-
erated which in extreme cases may cause the muffl er to burst.
Hazard caused by blocked muffl er!
Blocked muffl ers can cause a dangerous overpressure to build up which may
cause the muffl ers to burst. Flying fragments may cause personal injury and
damage to property.
Therefore, the muffl ers must be replaced every 12 months and after each
change of desiccant.
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffl er:
◊ A loud cracking noise occurs which can injure your hearing.
◊ Particles carried in the air fl ow act like bullets and can injure your eyes or
skin.
Always wear eye and ear protection, therefore, when you are in the vicinity of
the dryer!
Depressurise the dryer and shut it down
(see page 33 ).
Unscrew muffl er as shown in the opposite
fi gure.
Replace muffl er and secure it.
Restart dryer (see page 34).
Renew dewpoint sensor
To ensure precision dew point measurement,
it is recommended to replace the dew point
sensor every year. This period depends howev-
er on the actual application and might thus be
extended accordingly.
