Maintenance and repair of the dryer
In order to allow maintenance work on the dryer to be carried out efficiently and
without danger for maintenance personnel, you should comply with the following
instructions.
Notes on maintenance
Warning!
Maintenance tasks may be carried out only by authorized and qualified
specialist personnel, and only with the plant in a switched off and
depressurised condition.
Danger!
There is a very considerable risk of personal injury, when carrying out
work on the activated and pressurised dryer.
Before commencing any maintenance tasks always shut down the dryer
as described on page 35!
Note:
According to national regulations an inspection of the pressure vessel
could be required periodically by an independent monitoring body.
Carry out all maintenance work only when the plant has been shut down and
depressurised!
Bolt connections must be undone with care! Note ram pressure values!
Otherwise emerging media may cause personal injury.
Do not modify the factory settings of the control system in any way without
prior consultation with the manufacturer.
Never carry out welding work on a vessel or modify the same in any way!
Following maintenance work, always check all flange and bolt connections
for leakage and secure seating.
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.
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.
