IMPORTANT NOTES:
• Make sure that you maintain a good grip
on the air conditioner so that it does not
fall out of the window opening during the
installation.
• Make sure that you center the unit in the
window so that the L-brackets mate with
the bottom guides. If the unit is not centered properly, it could slide out of the
opening.
3. Carefully lift the air conditioner, and center
it in the window opening, then slide it into
place so that the bottom guides drop into
the two L-brackets you installed in step 2.
