Start up dryer
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffl er:
◊ A loud cracking noise occurs which can injure your hearing.
◊ Particles carried in the air fl ow act like bullets and can injure your eyes or
skin.
Always wear eye and ear protection, therefore, when you are in the vicinity of
the dryer!
Risk of injury from crushing!
During the switching from adsorption to regeneration, there is a risk of injury
from crushing at the universal shaft and the drives. During switching, stay clear
of these components!
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 plant is still pressurised! A sudden escape of pressure may cause
serious injuries.
Before carrying out any work on the dryer, fi rst depressurise the plant.
◊
The more powerful the dryer is, the more noise may be generated during operation. There-
fore, the operator 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 offi ce or person.
◊
In the event of an emergency or if a safety-relevant disruption occurs (e.g. escaping com-
pressed air, defective component), the dryer must be shut down immediately as described
in the section on page 33). The unit may only be restarted after all defects have been
eliminated.
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
(see installation example on page
22
).
Ensure that the compressed air system upstream of the dryer is pressurised. If necessary,
pressurise (switch on compressor).
Slowly open compressed air inlet valve!
Avoid sudden pressure build-up in any circumstance! 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!
Slowly open the compressed air inlet valve, installed by the owner, upstream of the dryer.
Switch on dryer: to this end, set the ON/OFF switch to
I
If the dryer is taken into operation for the fi rst time, or after a change of drying agent, the
following intermediate step is meaningful. In the case of a restart situation, the following
intermediate step can be skipped.
