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 depressur-
ised!
◊ Do not modify the factory settings of the control system in any way without prior consulta-
tion 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 ttings as steps or holding points! The components might fracture,
or the distortions which occur may cause internal damage on the dryer. It is possible to get
injured by slipping from the components with consequent breakage of the same and subse-
quent expulsion of the compressed air!
◊ Never leave tools, loose parts or cloths in, at or on the dryer.
◊ Following maintenance work, always check all ange and bolt connections for leakage and
secure seating.
◊ Only use replacement parts that are suitable for the relevant function and meet the techni-
cal requirements stipulated by the manufacturer. This is always the case, if you use original
replacement parts only.
Removal and disposal
Hazard due to a sudden release of pressure!
Never remove any parts of the dryer, or manipulate the same in any way, for as
long as the dryer is still pressurised! A sudden escape of pressure may cause
serious injuries.
Depressurise the plant before carrying out any work on the dryer.
Notes on the disposal of used desiccant
As the used desiccant is contaminated with various substances, its properties differ from
those of new desiccant. For this reason, the manufacturer or supplier of desiccant cannot
give any information on the used product.
Deliver used desiccant to a controlled dumping while heeding local of cial regulations.
Waste codes
◊ New product: 060899 (European waste code).
◊ Used product: These codes are governed by the industrial use and must therefore be deter-
mined by the waste originator.
