Maintenance and repair of the dryer

KA-MT 10-95/D3
To ensure precision dew point measurement,
it is recommended to replace the dew point
sensor every year. This period depends howev-
er on the actual application and might thus be
extended accordingly.
Dewpoint sensor (1)
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.
In order to limit the impact on the dryer operation to a minimum, we recommend that you
contact the manufacturer well in advance and order a new dewpoint sensor. 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 30 )
Loosen the screw at the adapter (1) and disconnect signal cable with the adapter and
seal.
Remove dewpoint sensor from the sensor cell (3) by turning the nut (2).
Take the new dewpoint sensor (2) from the box, remove the protective caps (4, 5) and
screw it into the sensor chamber (3).
Place seal onto sealing face; connect adapter (1) and secure it by tightening the screw.
If no other maintenance work is to be carried out: Restart the dryer (see page 31 ).
Place the protective caps (4, 5) onto the old dew point sensor and dispose of it in accor-
dance with the applicable regulations.
