2. Slowly pressurise the plant by opening valve A slowly.
Constantly check the pressure at the pressure gauges. Both absorbers must reach operating pressure.
3. Switch on the power supply to the electronic control.
4. The control system starts the pressure build-up phase in the two adsorbers. Subsequently, the regeneration
phase is started in one adsorber, while the adsorption phase is started in the other.
5. Note that moisture from the ambient air might have entered the vessels and the adsorbent during transport and/
or storage of the plant. Before commissioning the plant, it should therefore be regenerated for minimum 3 hours
before shut-off valve B to the compressed air system is opened!
6. Slowly open valve B, thus connecting the plant to the compressed air system.
7. If valve C was open during commissioning, close it.
The plant is now fully commissioned and works automatically and continuously from now on.

WARNING Risk of personal injury during plant operation
During plant operation, the following mechanical risks exist: Sudden pressure relief in
components such as the silencers; loud blow-out noise during pressure release.

6.1. Operating mode

When the plant is in operation, you can select the desired operating mode, i.e. "time control" (see "4.4.3. Time
control", page 33) or "dew point control" (see "4.4.4. Dew point control (optional)", page 33) at the text display.
In standard operating mode, the plant is run continuously and automatically.
With intermittent operation (see "4.8. Intermittent operation", page 34), the plant remains in stand-by mode after
completion of the pressure build-up, and if no compressed air is consumed.
Stand-by state is indicated on the standard control unit by an LED. In the version with dew point control, it is
indicated in plain text.

6.2. Service mode

In service mode, service messages are displayed and can be acknowledged. These messages are displayed,
if service A or B must be performed and when a service has been completed (see "2.3.4.1. Service messages
(standard version)", page 17).
