Operate the dryer only within the permitted limits (see type plate). If the unit is
operated under conditions where the defined limit values are exceeded, it is
exposed to stresses for which it is not designed. This can result in
malfunction or failure of the dryer.
The higher the capacity of the dryer, the more noise it produces during
operation. The operator must therefore provide suitable protective equipment
(earmuffs).
The dryer must be regularly inspected for visible damage. Any observed
changes, including changes in the operation behaviour, must be immediately
reported to the responsible person.
In the event of an emergency and if safety-relevant malfunctions are
observed (e.g. escaping compressed air, higher noise level, defective
components), the dryer must be immediately switched off (see page 42). The
unit may only be restarted after all defects have been eliminated.
Servicing and troubleshooting the dryer
Risk of injury from escaping compressed air!
Never remove any parts of the dryer, or manipulate the same in any way,
as long as the unit is pressurised! Suddenly escaping compressed air
might cause serious injuries.
Prior to any work, release all pressure from the unit.
Carry out all maintenance work only when the plant has been shut down and
depressurised!
Do not modify the factory settings of the control system in any way without
prior consultation with the manufacturer.
Bolt connections must be undone with care! Note ram pressure values!
Otherwise emerging media may cause personal injury.
Never carry out welding work on a vessel or modify the same in any way!
Never use pipes and fittings as steps or holding points! The components
might fracture, or the distortions which occur may cause internal damage on
the dryer. There is a risk of injury by slipping off the components, components
breaking off, and expanding compressed air!
Never leave tools, loose parts or cloths in, at or on the dryer.
Following maintenance work, always check all flange and bolt connections for
leakage and secure seating.
Only use replacement parts that are suitable for the relevant function and
meet the technical requirements stipulated by the manufacturer. This is
always the case, if you use original replacement parts only.
