Daily maintenance tasks
Carry out visual and function check on the complete dryer
Check dryer for external damage or unusual noise generation.
Duly eliminate any defects found.
If message SEr. is displayed, a routine service must be completed:
Contact the service department of the manufacturer.
Clean dryer
Remove any loose dust by means of a dry cloth, and, if required, also by means of a
moist and well wrung cloth.
Clean the surfaces with a moist well wrung cloth.
Check dam pressure
If, following depressurisation of a vessel, e.g. after the expansion phase, the overpressure
has not decreased to 0 bar, then there is a residual pressure, designated as dam pressure, in
the vessel.
Check for dam pressure: if the dryer functions correctly, the respective pressure gauge
indicates 0 bar. Then there is no dam pressure.
If the dam pressure is greater than 0.3 bar:
Depressurise the dryer and shut it down (see page 33).
Dam pressure can be caused by:
- a blocked muffl er,
- a blocked dust sieve or
- drying agent which is too old.
The respective necessary maintenance measures are described in the following sections.
Maintenance work to be completed every 12 months
Renew fi lter element of the control air fi lter
The control air fi lter is used to clean the control air and thus ensures that the valve actuators
are working properly. Contaminated or damaged control air fi lters might lead to malfunctions
in the valve actuators. The fi lter must therefore be inspected at least once every year.
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).
