With an increasing duration of operation, a higher overpressure can be indicated
during regeneration. This overpressure during regeneration is also designated as
dam pressure.
The dam pressure should not exceed 0.3 bar, otherwise read the instructions
on page 45.
During the pressure build-up phase the indication on the pressure gauge
should again rise to operating overpressure level.
Emergency shutdown
In the event of an emergency, shut down the dryer as described on
page 39.
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), the dryer must be shut
down immediately as described in the section on
page 39)
.
The unit may
only be restarted after all defects have been eliminated.
