Start up dryer
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffler:
A loud cracking noise occurs which can injure your hearing.
Particles carried in the air flow 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!
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, first depressurise the plant.
The more powerful the dryer is, the more noise may be generated during
operation. Therefore, 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 97/23/EC.
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), immediately close the
compressed air supply line and set the ON/OFF switch of the dryer to
0
in
order to disconnect it from the power supply. Afterwards depressurise the
dryer (see also chapter
,
page 37). 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 24).
►
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!
