Maintenance and service
This section describes the process of maintaining the adsorption dryers including the overall
safety precautions which have to be taken during maintenance work.
The cleaning intervals depend largely on the operating conditions. Therefore check your
adsorption dryer after every drying process.
If required, the inside of the device can be carefully cleaned with compressed air. Wear pro-
tective goggles and ensure that all internal components are cleaned.
• Rotor, rotor drive, drive belt, fan, heater and hygrostat (if any) must be checked at regular
intervals.
The device casing can be opened and inspected after removal of the screws and taking off
the lid.
