instructions

Warning against hazardous electrical voltage

Different parts of the dryer carry electrical current.

 

These parts may be

connected, opened, and maintained by authorized specialist personnel only.

Warning against overpressure

The entire dryer is under pressure. Before commencing any work, the plant
must be depressurised.

Warning against sudden air ejection

When the vessels are depressurised, air flows suddenly out of the sound
absorber:

„

 

This causes a sudden loud cracking noise.

„

 

Due to particles carried in the air flow, there is a very considerable risk of
eye injury.

When working on the dryer, always wear eye and ear protection equipment.

Skid risk

When emptying and filling the vessels with drying agent, there is a risk of
skidding caused by spilt drying agent.
