Normal start
If the dryer has not been used for more than 3 months, refer to section Initial start-up. In all other cases, proceed
as follows:
1. Cut off the air supply from the compressor towards the dryer by closing the external inlet valve.
2. Close the air supply towards the purge control sensor.
3. Close the external outlet valve between the dryer and the air consumer.
4. Start the compressors and slowly open the external inlet valve.
5. Ensure the dryer is powered on.
6. Gradually open the air outlet valve.
7. If applicable, close the bypass valves of the dryer.
8. Open the air supply towards the purge control sensor.
During operation
• At regular intervals, check the status of the dryer on the central controller display (ES-MED).
If the warning/alarm LED is alight, consult section
• Check the dew point regularly.
If the dew point is too high, consult section
• Regularly check the differential pressure gauge of the filters. Replace the filter cartridge if the pressure
drop is too high.
• Regularly check the sight glass on the filters. Water in the sight glass means the automatic drain is
inoperative.

Close the external inlet valve in case the compressor needs to be restarted. The high air
speed in the start-up phase of the compressor may damage the desiccant.
• All valves, couplings and pipes used/installed after the unit must be free from oil and
grease (hydrocarbon contamination below 550 mg/m
50 micrometer).
• For the location of the external inlet valve and external outlet valve (customer's
installation), see section Installation proposal.
