Connectivity with KX6 series
[A] [B]
SAF is the energy recovery ventilation unit which can recover heat energy from exhaust air to supply air and "has no air processing
function, but FDU-F is air processing unit which can treat the supply air closer to room temperature by cooling or heating in connection
with KX6 refrigerant system and exhaust air is discharged to outside of the room.
Combination with KX6 series
In case OA processing units only
are connected with KX6 outdoor units
In case both of OA processing units
and dedicated air-conditioner
are connected with KX6 outdoor unit.
The total capacity of FDU-F is 50~100% of outdoor capacity
and max quantity of FDU-F is 2 units.
