Installation Procedure
Installation of indoor unit
Installation for air duct of indoor unit 1. Installation for air supply duct
This type of unit uses circular air duct with its caliber of 180mm.
An additional transitive air duct is necessary for the circular air duct to connect to the air supply inlet. It should be also connected to its respective air diffuser separately. See Fig.1. Adjust the wind speed of each air diffuser outlet to keep in line on the whole, so as to meet a demand of the air conditioner in the room.
