may be 20cm X 20cm or 16cm X 25cm or 10cm X 40cm for each Plasma unit
installed. This opening may be on the top, front or side of the cabinet, it may be
orientated vertically or horizontally. The return air opening must be no more than 6M
away from the Rangehood location and vent into the same room. The opening must
not be made in the bottom of an overhead cabinet.

return air opening should be as large as practically possible for the application, to
reduce the possibility of air noise from the air returning to the kitchen. The return air
opening must be placed in a location that does not allow end user access to the
Plasma Unit or Rangehood.
