5 ton High Efficiency A5 Duct Technical Manual

For steel roof beam structure, install and use directly the supporting angle steel.
Overhang the indoor unit onto the hanging screw bolts with block. Position the indoor unit in a float
level by using the level indicator, otherwise it may cause water leakage.
2.2 Designing and connecting the duct
Check the filter of the indoor unit, and then install the canvas air passage underneath the dust proof
net.
Install a filter at an easy-to-maintain place such as intake pipe. If without the filter, the duct will gather
on the air heat exchanger and lead to fault and water leak of the air conditioner.
In order to suppress noise effectively, install noise suppression and sound insulation devices,
especially in the noise-sensitive spaces such as meeting rooms.
For connection of the flange plane, use non-flammable canvas adapter to prevent transmission of
vibration.
Air inlet and air outlet duct should be apart far enough to prevent air outlet entering air inlet.
