The size of sealed room should not be too small; otherwise it will affect the unit normal functionality. See diagram

4.4 Placement of System
Selecting a good location for your air conditioner is the most important part of your preparation. Be sure to consider
the size of the area you are cooling, the air distribution needs, and the size of the unit you have chosen. Keeping in
mind that cool air has a tendency to fall; it is highly recommended that you locate the supply air grille as high as
possible in the cabin. Don’t leave the flexible ducting too long; otherwise it will lower the efficiency of the unit. Refer
to the proceeding diagram as an example.
