RTAF Operating Map
To check unit configuration versus ambient, refer
to operating map figure below: Standard ambient,
High ambient or Low ambient.
Sound power levels
− Standard ambient units:
Discharge
-10°C ≤ Air temperature ≤ 46°C
− Low ambient units:
Measurement conditions: -20°C ≤ Air temperature ≤ 46°C
Measurements taken in a room adjacent to the room containing the FWD, at the outlet of the rectangular duct (1.5 m
− High ambient units:
long) fixed to its discharge opening. -10°C ≤ Air temperature ≤ 55°C
