8.0 CONDENSATE DRAIN
8.1 Drain valve maintenance
•
Close the ball valve located on the filter/stop installed at the drain trap inlet.
•
Depressurize the trap by pushing the TEST button on the control panel.
•
Unscrew the plug in the end of the filter/stop to access the filter screen (F) and
clean it with a compressed air jet.
•
Reassemble and open filter/stop valve.
Cleaning of the drain solenoid valve
8.2 NO LOSS CONDENSATE DRAIN
Electronic drain discharge is the new discharger applicable
to any compressed air systems. It eliminates the
condensate without wasting compressed air.
Electronic drain discharge starts automatically, without the
need of any adjustment. The condensate discharge occurs
to the use of an electronic sensor, which detects the
amount of condensate in the integrated water collecting
tank. The level sensor drives start and duration of the
drainage, so preventing any wasting of compressed air.
At the end of installation, put the system under pressure
and push the TEST key repeatedly to eliminate the air
bubbles contained in the discharger inlet fittings.
To this discharger will be applied the Beko warranty
conditions.
