Monitoring dryer operation
The dryer operates fully automatically. However, you should carry out the regular
checks described in the Chapter
Maintenance and repair of the dryer
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!
With dewpoint-sensing control
Display of dewpoint
The digital display at the front of the switch box shows the currently measured
dewpoint. The range of display is –100 °C (-148 °F) to +20 °C (68 °F). The
dewpoint at which a switchover is made is preset at the factory.
► After commissioning or extensive maintenance work, check the dewpoint
display at the dryer.
Under certain circumstances, the desired dewpoint is only reached after
prolonged operation.
