CAUTION
 • We strongly recommend the removal of the old 
wall sleeve and the installation of a new LGE 
Wall Sleeve. If you decide to keep the existing 
wall sleeve, you have to redirect the louvers 
at the back of the wall sleeve illustration. The 
use of pliers is recommended. If you DO NOT 
redirect, you run the risk of poor performance 
or product failure. This is not covered under the 
terms of the LGE warranty.
 • Pick a location which will allow the conditioned 
air to blow into the area you want. Good 
installation with special attention to the proper 
position of the unit will lessen the chance that 
service will be needed.
