Emergency shutdown
In the event of an emergency, shut down the dryer as described on
page 35.
Start up dryer
The more powerful the dryer is, the more noise may be generated during
operation. Therefore, the owner must provide suitable protective equipment
(e.g. ear protection).
Only operate the dryer within the permissible limits. By operating the dryer in
conditions for which it has not been designed, functional faults may be
caused.
Depending on the size of the dryer and the compressed air network and the
respective legal requirements in your country, it may be necessary to perform
initialisation according to the directive for pressure equipment.
Check the dryer regularly for externally visible damage and defects. Any
changes, even in its operating behaviour, must be reported immediately to
the competent office or person.
In the event of an emergency or if a safety-relevant disruption occurs (e.g.
escaping compressed air, defective component), the dryer must be shut down
immediately as described in the section
Trockner drucklos machen und außer
on page 35). The dryer may only be restarted after all
defects have been eliminated.
Before start-up, ensure that no tools or other foreign parts have been left lying
in a part of the dryer where they might pose a hazard to the dryer being
started up.
Open compressed air supply and switch on dryer
For start-up, please proceed in the sequence shown here.
► Ensure that the compressed air inlet and outlet valves installed by the owner
are closed.
► Ensure that the compressed air system upstream of the dryer is pressurised.
If necessary, pressurise (switch on compressor).
The ambient temperature must not drop b
Make sure sudden pressure build-up is avoided! If pressure builds up too
fast, this may cause damage to the dryer. Therefore, the compressed air
inlet valve must always be opened quite slowly!
► Installation area
► Check that the full operating pressure is shown on both pressure gauges.
► Switch on dryer: to this end, set the ON/OFF switch to
I
.
If the dryer is taken into operation for the first time, or after a change of desiccant,
the following intermediate step is meaningful. When restarting (after a few hours),
the following intermediate step can be skipped.
