SECTION I
Drain Kit
A field supplied condensate drain kit is required for total
elimination of cooling or heat pump condensate.
When installing a condensate drain kit, (either internal or external drain), it is recommended that installation of the drain
kit be completed before installing the wall sleeve. Instructions
for drain kit installation are shipped with the drain kit.
Wall Structure
3. Drill two 3/16" holes through each side of the sleeve
approximately 4" from top and 4" from bottom of sleeve.
Screw four #10 x 1" screws (included) or appropriate
fasteners for your installation, through holes in sides of
opening.
NOTE: Do NOT put any screws or drill any holes in the bottom
of wall sleeve, unless required by the installation of a PXDR10
Condensate Drain Kit.
A subbase or other means of support MUST be used if sleeve
projects more than 8" into room. Refer to subbase installation
instructions for additional information.
Sleeve Installation
For Deep Wall Installation See Section II
The following instructions apply ONLY to walls less than 13
1/4"" in depth.
1. From inside the building, position wall sleeve in opening
and push through the wall so it protrudes at least 1/4"
on the outside, note Figure 2.
2. Position the wall sleeve so that it is positioned with a
slight tilt towards the outside to facilitate condensate
drainage. It should be level side-to-side. DO NOT allow
any pitch toward the inside.
Figure 2. Dimensions
4. Apply sealant around the wall sleeve where it projects
through the inside and outside wall surfaces. Apply
sealant to screw heads or tops of fasteners used in Step
#3.
NOTE: When sealing sleeve on outside of building, be care-
ful NOT to let sealant block the two condensate drain
holes or the four overflow slots at the bottom flange of
the sleeve.
5. If chassis and exterior louver are to be installed later,
leave the weatherboard and center support in place,
otherwise remove and dispose of them.
