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 cause much more noise. It is recommended to install the air conditioner in 
downward return air mode 2 if enough space is available.
Body installation
1. Use M10 lifting bolts.
2. Ceiling removal: For different building structures, please consult with indoor decoration personnel about actual 
conditions.
a. Ceiling reinforcement: To ensure the ceiling is horizontal and will not shake, the ceiling base frame must be 
reinforced.
b. Cut off and remove the ceiling base frame.
c. Reinforce the end faces left when the ceiling is removed and further reinforce the base frame that x both ends 
of the ceiling.
d. After the body installation is complete, it is time to install pipes and wires. Before installation, choose a suitable 
installation position and determine the outgoing direction of pipes. Especially in case that a ceiling exists, please 
pull refrigerant tubing, drain hose, indoor and outdoor connecting wires, control wires to their connection positions 
prior to hanging the machine.
