11. Gradually open the external outlet valve, keeping the pressure inside the dryer above
65.3 psi (4.5 bar).
12. As required, close the bypass valves of the dryer.
13. Press the stop button 0 and switch off the voltage to the dryer.
14. Plug the PDP-sensor.
15. Open the air supply towards the PDP-sensor.
At initial start-up, dust can be released. It is recommended to replace the
cartridges of the silencers after approximately one week of operation. An
optional Sonic nozzle is available to avoid damaging of the desiccant at start up
If the application allows air that is not dried optimally, the valve towards the air
consumer may be opened even when the PDP temperature is too high. In this
case, it will take more time for the desiccant to dry completely
6.2 Start-up
Description
If the dryer has not been used for more than 3 months, refer to the chapter "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. Cut off the air supply towards the PDP-sensor.
3. If installed, close the external outlet valve between the dryer unit and the dry air
consumer.
4. Slowly open the external inlet valve.
5. Switch the dryer on.
6. Gradually open the external outlet valve, keeping the pressure inside the dryer above
65.3 psi (4.5 bar).
7. As required, close the bypass valves of the dryer.
8. Open the air supply towards the PDP-sensor.
An optional Sonic nozzle is available to avoid damaging of the desiccant at start
up.
If the dryer is started and stopped automatically, precautions must be taken to
avoid damaging of the desiccant.
Close the external inlet valve in case the compressor needs to be restarted. The
airspeed in the start-up phase of the compressor may damage the desiccant.
