Recalibration of dewpoint sensor (optional)
In order to ensure accurate dew-
point measuring, we recommend
recalibrating the dewpoint sensor
at least every 12 months. The
recalibration must be carried out
by the manufacturer. This period
depends however on the actual
application and might thus be
extended accordingly.

Warning!
The dew point sensor is a sensitive measuring device. It can be damaged if
subjected to forceful vibrations or shocks. Therefore, please handle the
dew point sensor with great care at all times.
For calibration, the pressure dewpoint sensor must be dismantled. In order to
limit the impact on the dryer operation to a minimum, we recommend that you
contact the manufacturer well in advance (for contact details, see page 9) and
order a new dewpoint sensor. Upon receipt of your old pressure dewpoint sensor,
we will issue a credit note.
After receipt of the new pressure dewpoint sensor, replace the sensor as follows:
►
Hold the box of the dewpoint sensor ready.
►
Release pressure from dryer and shut down the unit (see page 43).
