►
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 39).
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.
Weekly maintenance tasks
Check differential pressure on the filters (option)
For details see filter instruction manual.
Monthly maintenance tasks
Check the function of the condensate trap on the upstream filter (option)
For details see filter instruction manual.
