The distance between air duct outlet and air conditioner outlet is according to the length of
actually installed air duct and in service behavior of the static pressure terminal: Installation
sketch map for long and short air duct is showed below, when connect to short air duct, using
low static terminal (terminal color is white), the distance between air duct outlet and air
conditioner outlet is no more than 0.5m; when connect to long air duct, using middle static
terminal (terminal color is red), the distance between air duct outlet and air conditioner outlet
could be within 5m at this point.
As figure shown, suspend and install the unit.
Drain piping of condensed water should keep a downhill grade of 1% or more. Use insulating
pipe to cover the drain piping of condensed water to keep warmth.

Installation for air duct of indoor unit
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.
