Operating instructions
Safety
Always observe all relevant safety instructions.
Initial start-up
To start up the dryer for the first time or after a long period of standstill, proceed as follows:
1. Open the bypass valves (if installed) of the dryer.
2. Close the air supply towards the PDP sensor (dryers with PDP sensor).
3. Close off the air supply from the compressor towards the dryer by closing the external inlet valve (if
installed).
4. Close the outlet valve (if installed).
5. Remove the silencers to prevent the silencers from getting clogged by the desiccant and wear a dust
mask, safety glasses and ear protection. (This is only required at initial start-up or after the desiccant
was replaced).
6. Start the compressor and wait for pressure.
7. Slowly open the inlet valve.
8. Check the connections of the dryer for air leaks and remedy if necessary.
9. Switch the dryer on by pushing the Start button (14) on the Purelogic™ controller.
10. Let the dryer operate for several hours with the external outlet valve closed.
11. In case the silencers were removed, refit the silencers.
12. Gradually open the external outlet valve.
13. If applicable, close the bypass valves of the dryer.
14. Open the air supply towards the PDP sensor (dryers with PDP sensor).
If the application allows air that is not completely dry, the valve towards the dry air
consumer may be opened even before the optimal Pressure Dew Point (PDP) is
reached. In this case however, it will take more time for the desiccant to dry completely.
At initial start-up, and specially when the dryer is loaded from the beginning, it can take
a long time before the dew point is reached.
For a dew point of -100 ˚F, it can take up to more than 10 days before this value is
reached.
It is therefore recommended to operate the dryer for a number of days with the outlet
valve closed.
