Installation
Installing the Wall Sleeve in Wall Opening
1. Position the wall sleeve into the wall. The rear (outside) edge of the wall sleeve should extend
at least 1/4” beyond the outside wall in order to properly caulk, prevent sealing the drain
holes in the rear flange of the case, and to facilitate easy installation of an accessory drain (if
desired). If it is desired to have the rear grille flush on the outside, a drip rail must be installed
under the case and caulking applied between the drip rail and case.
