-
If the unventilated area is smaller than the minimum installation area, the air conditioner
should not be installed in this area.
-
The installation height is the minimum installation height, that is, the minimum installation
height of the cold air pipe or indoor unit, whichever is the lowest. The following table is
determined according to the minimum installation height of 1.8 meters and 2.2 meters
-
If the required minimum installation height is less than 1.8 meters, the minimum installation
space must be recalculated.
