Wall Sleeve Installation
Afterthewallopeningischeckedandapprovedforstrength,
location, size, and clearances, install the wall sleeve as
follows:
1. Remove the outside enclosure panel from the wall
sleeve.
3. Locatethesleevewithintherangeofminimumprojec-
tions, as shown in Figure 2, so both sides are at least
the minimum projection from the wall.
2. Slide the wall sleeve into the wall opening. Do not
distortthecabinetshapetofitthewallopening;theunit
chassis must fit snugly and uniformly into sleeve.
4. Check the level of the wall sleeve. For proper drain-
age, the sleeve should be level from side to side and
one-quarter bubble front to back (outside).
Preinstallation Considerations(cont.)
Waterproof barrier should remain in place until the unit
is installed. An accessory metal front panel is available
and sold separately.
A condensate drain tube is included. (Figure 10)
Attached to bottom rear flange of wall sleeve with two
