NOTE 
■ Before installing the air deflector, remove the mesh enclosure to 
avoid blocking the air supply.
■ Mounting the shutter on the unit limits the air volume, cooling 
(heating) capacity, and efficiency depending on the shutter 
angle. Do not mount the shutter or keep it angled to under 15°.
■ Only one bending site is allowed in the air duct (see as above 
figure) or the unit may not function normally.
■ Please install a soft connector between the air duct and machine 
to reduce noise.
■ The Air-duct device should not larger than the cover, because 
you have to lift the upright and panel to dismantle them.
■ Independently install the wind scooper. Do not combine the wind 
scoopers between units or a fault may occur. Figure 4-34 shown 
shows incorrect installation.
