RTAF Operating Map R134a / R513A / R1234ze
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:
-10°C ≤ Air temperature ≤ 46°C
Discharge
− Low ambient units:
-20°C ≤ Air temperature ≤ 46°C
Measurement conditions:
− High ambient units:
Measurements taken in a room adjacent to the room containing the FWD, at the outlet of the rectangular duct (1.5 m
-10°C ≤ Air temperature ≤ 55°C
long) fixed to its discharge opening.

- For RTAF 250 to 450 with a single pass evaporator, Leaving Water Temperature cannot exceed 18.3°C.
- The curve of limit current may vary from one machine size to another, but it will always be a parallel curve to that
shown in the operating map.
* Economizer is only available in the RTAF sizes 355 & 450 SE/HE/XE and 370, 400, 510 & 550 HSE.
