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 37).
Dam pressure can be caused by:
a blocked muffler,
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 muffler
The dryer is equipped with a muffler. If the muffler becomes blocked, a dam
pressure is generated which in extreme cases may cause the muffler to burst.
Hazard caused by blocked muffler!
Blocked mufflers can cause a dangerous overpressure to build up which
may cause the mufflers to burst. Flying fragments may cause personal
injury and damage to property.
Therefore, the mufflers must be replaced every 12 months and after each
change of desiccant.
