This series of air conditioners can be arranged in two air return modes: 1. Air return from the back (Factory default);
2. Air return from the bottom (can be adjusted on site. See the following gures.)
Note:
The downward air return mode will increase noise 3-5dB(A). It is recommended to install the air conditioner in
downward return air mode 2 if enough space is available.
