Security Brackets Installation
(It is important to install these brackets
to prevent the chassis from being
pushed into the room from the outside.)
Ŷ The brackets must be installed so the flanges are
hooked behind the inside flanges of the wall sleeve.

the sides of the chassis.
To install the security bracket without fully removing
the front grille:
1. Grasp the front grille louvers on both sides at the
recess and pull forward.
2. Remove the filter by pulling forward and out.
3. Remove the two Phillips head screws located in
the upper corners of the grille louver opening. Do
not discard screws.
4. Grasp the left and right rear edges of the front
grille about 6” from the top and pull outward to
release the tabs on the inside of the grille from
the slots in each side of the metal chassis cover.
When released pull out both bottom corners of the

on the lower area of the metal chassis cover.
5. Locate the 2 metal brackets stamped 26” that were
included with the air conditioner. Hook the short
flange of the bracket behind the sleeve inside edge
and rotate it so the long side can be pressed flat
against the metal chassis cover. Adjust so the
bracket can be secured to the metal chassis cover
by 2 screws included with the bracket. Only one
bracket will be needed and can be installed on
either side of the chassis.
6. To reinstall the front grille, push the lower corners
to toward the sleeve until the side tabs click into
the mating slots. Reinstall the two screws removed
earlier and replace the filter and louvers.
For 26” sleeves, hook the short flange of the 26”
bracket behind the sleeve inside edge and secure
to the unit with the two screws provided. Repeat
on the opposite side.
