DIRECT FREE COOLING PLENUM (UNDER UNITS)
This accessory is installed on the top of the unit, and is used to
take in cool outside air and then deliver it directly into the air-
conditioned environment. The plenum is supplied with 2
motorised dampers (one for the outside air + 1 for the inside
air), managed by the unit's microprocessor controlled, which
modulate the quantity of air taken in from the outside to ensure
the room temperature set point is maintained.
This accessory is not available on AF units.
