6 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. If installed, open the bypass valves of the dryer.
2. Close off the air supply from the compressor towards the dryer by closing the external inlet
valve (if installed).
3. If installed, close the
outlet valve.
4. 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).
5. Start the compressor and wait for pressure.
6. Slowly open the inlet valve.
7. Check the connections of the dryer for air leaks and remedy if necessary.
8. Switch the dryer on by putting main switch S1 in position I.
9. Let the dryer operate for several hours with the external outlet valve closed.
10. In case the silencers were removed, refit the silencers.
11. Gradually open the external outlet valve.
12. If applicable, close the bypass valves of the dryer.
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 the air
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.
It is therefore recommended to operate the dryer for a number of days with the outlet
valve closed.
Normal start
If the dryer has not been used for more than 3 months, refer to section Initial startup. 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. If installed, close the external
outlet valve between the dryer and the dry air consumer.
3. Start the compressor and slowly open the external inlet valve.
4. Switch the dryer on by putting main switch S1 in position I.
5. Gradually open the air outlet valve.
6. If applicable, close the bypass valves of the dryer.
