Safety notes on specific operating phases
16
HDK350_EN_01_2005-05-10
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.
Loud noise generation!
During expansion the pressure is released suddenly through the
expansion valve. A loud cracking noise may occur.
Always wear ear protection, therefore, when you are next to the dryer
during operation.
The more powerful the dryer is, the more noise may be generated during
operation. Temporarily, the actual noise emission may even exceed
95 dB(A). 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
Depressurising and shutting
down the dryer
on
page 43)
.
The unit may only be restarted after all defects
have been eliminated.
Maintenance of the dryer and fault removal
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 maintenance work only when the plant has been shut down and
depressurised!
The factory settings on the control board in the switchbox must not be
changed on any account without prior approval by the manufacturer.
Bolt connections must be undone with care! Note ram pressure values!
Otherwise emerging media may cause personal injury.
Never carry out any welding on a vessel or change the same in any other
way!
Never use pipes and fittings as steps or holding points! The components
might fracture, or the distortions which occur may cause internal damage on
the dryer. There is a risk of injury by slipping off the components,
components breaking off, and expanding compressed air!
Never leave tools, loose parts or cloths in, at or on the dryer.
Following maintenance work always test all flange and bolt connections for
leak tightness and secure seating.
