1) The components D, E and the drain fitting of the kit are mount-
ed on the bottom of the wall sleeve prior to the installation of
the sleeve. When a subbase in not used, a suitable area on
the bottom of the sleeve is selected which is inside the room.
And when a subbase is installed, the drain should be installed
at a minimum of 3 – 1/2 inch from the front flange of the wall
sleeve. A minimum clearance should be provided for the sub-
base as shown in the figure on the right.
2) Cut out the template in the lower right hand corner of the
sleeve to locate the field drilled holes. See detail A on the last
page on how the components have to be installed after the
holes are drilled in the bottom of the wall sleeve. If the drain
fitting is not connected to an indoor drainage system immediately after the wall sleeve is installed, then it must be plugged
with a cork to prevent indoor water spilling in case of rain.
An indoor tube or hose must be installed on the drain fitting and inter connected to the drain system inside the building.
Install the two blank off plates C and gaskets A on the outdoor portion(flange) of the wall sleeve as shown in the figure on
the last page. These components may be installed after the wall sleeve is secured in the wall opening just prior to the instal-
lation of the condenser grille and chassis.
