Start-up
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffler:
A loud expansion noise is caused which may damage your hearing.
Particles carried in the air 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.
Carry out all prescribed tests and checks.
The factory settings on the control board in the switchbox must not be
changed on any account without prior approval by the manufacturer.
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.
Emergency shutdown
In any emergency, proceed as described in the section on page 35.
Monitor operation
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffler:
A loud expansion noise is caused which may damage 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!
Only operate the dryer within the permissible limits (see type plate). By
operating the dryer in conditions that go beyond the defined values, the dryer
is subjected to loads for which it has not been designed. This may cause
functional defects.
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).
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 on
page 35)
.
The unit may
only be restarted after all defects have been eliminated.
