Installation modes of Indoor unit
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 figures.
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 (figure 2) if enough space is available.
