Maintenance work to be completed every 12 months
Check air quality
Especially for critical applications, we recommend to annually check the quality of the pro-
cessed medical breathing air (this check should be carried out by a qualifi ed authority).
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!
