VACUUM MODE

 

Air/Water is extracted from the playing field via subsurface drain lines.  The air and water are then separated in the air/water separator.  The air continues to flow to the SubAir room, proceeds through the SubAir Flow reversing valve, and finally discharged through a exhaust louver.  Water that is removed from the playing field is subsequently discharged air/water separator through float controlled submersible pumps.  The field drainage piping is isolated from the main drain via an isolation valve located in the air/water separator.
