CA-239 Wall Sleeve Kit
The CA-239 wall sleeve kit is designed to facilitate the installation of
Magic-Pak units by providing an accurate opening to properly accept a
Magic-Pak unit. During the construction of a building, the wall sleeve
allows for the unit to remain off-site until the construction is completed.
The wall sleeve is comprised of four assemblies (top, bottom and left and
right sides) which assemble easily to form a correctly sized rectangular
box to receive a Magic-Pak unit.
When installed and securely fastened to the supporting wall, the wall
sleeve provides easy access to the finish wall for weather sealing.
The wall sleeve must always be fastened to the supporting wall
and never to the finished wall.
Inspection of Shipment
Upon receipt of equipment, carefully inspect it for possible shipping
damage. If damage is found, it should be noted on the carrier’s freight bill.
Damage claims should be filed with the carrier immediately. Claims of
shortages should be filed with the seller within five days.
Wall Sleeve Assembly
To assemble the wall sleeve, refer to the following directions and Figure 7-
1 on page 7-4.
1. Slide top panel over side panels until retaining clips are engaged in
slotted openings.
2. Place side and top assembly down with the front flange against floor
and slide bottom panel into side panel slip strips until tabs on bottom
panels are locked in place.
3. Attach squaring braces to top and side panels using existing holes.
(Do not remove braces until wall sleeve is secured to building.)
4. Attach the support angles to top and side panels using the #8 x 3/8"
screws provided. Two sets of holes are provided in the panels for
attaching the support angles. The row of holes nearest the front of
sleeve will locate the support angles for 1" spacing and the second
set of holes will locate the angles for 3-3/4" spacing.
5. Wall sleeve must be square in opening before securing sleeve
to building. This is required to assure Magic-Pak unit will slide into
the sleeve.
6. Caulk all seams where bottom panel joins to side panels including the
front corners of bottom panel and the top of side panel slip joints.
Caulk sealing is best accomplished after the wall sleeve is assembled
but before it is placed in the wall opening.
