General safety notes
For your own safety, when carrying out any work on the dryer comply with
all applicable national safety regulations!
Risk of injury from escaping compressed air!
Never remove any parts of the dryer, or manipulate the same in any way,
for as long as the plant is still pressurised! Suddenly escaping
compressed air might cause serious injuries.
Before carrying out any work on the dryer, first depressurise the plant.
Hazard caused by exceeding the limit values!
The dryer may only be operated within the defined operating conditions.
Exceeding the maximum permissible conditions can cause serious
injuries and death.
The operating company must ensure the maximum operating pressure
and permissible fluid temperature are not exceeded by installing
corresponding safety devices.
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!
Attention! Start up dryer in discontinuous operating mode!
Discontinuous operation (cut-out mode) and correspondingly frequent
dryer start-ups can cause excessively high flow rates in the dryer.
Frequent pressure surges and excessive flow rates can damage the dryer
as well as its valves and fittings.
A start-up device prevents high flow rates from occurring in the dryer
even in the case of synchronised, automatic compressor start-up. For
discontinuous operation it is therefore necessary to install a pressure
retention valve downstream of the dryer.
Risk of falls!
The dryer must not be misused as a climbing aid! The components have
not been designed for such loads and could fracture.
