Close the external inlet valve in case the compressor needs to be restarted. The high
air speed in the startup phase of the compressor may damage the desiccant.
During operation
The LEDs for PDP warning and PDP alarm are only functional if the dryer is equipped
with a PDP sensor!
Stopping
To stop the dryer, proceed as follows:
1. If installed and if necessary, open the bypass valves of the dryer so that the application will
still receive compressed air.
2. Close the external
inlet valve between the compressor and the dryer and the external outlet
valve between the dryer and the dry air consumer.
3. Let the dryer operate for a period without consumption, to depressurize the vessels.
4. Switch off the dryer.
If the dryer is stopped for a longer period, keep the external inlet and outlet valve
closed to avoid moisture from entering the dryer.
Under no circumstances shall compressed air be allowed to flow through the dryer
when the electrical power is switched off. This will result in terminal failure of the
desiccant material and regeneration will no longer be possible.
