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