■ INSTALL CHASSIS IN SLEEVE (See Figures 6 to 9)
1. Inspect foam gaskets (top, bottom, both sides) on
chassis. Replace foam gaskets if torn or missing.

screws taped to the control box. Screw holes are
located on both sides of the mounting angles of the
chassis. Use only the top and bottom screw holes
on each side. See Figure 9.
IMPORTANT: The gaskets combine with the sleeve
face to create a weather barrier. If the chassis is
installed in a non-Carrier sleeve, this weather bar-
rier may not be effective.
Chassis weighs up to 150 lbs. For personal protec-
tion, seek help when lifting the unit. Lift unit by
holding unit basepan.
Failure to remove shipping tape will prevent fresh
air vent door from opening and may result in dam-
age to the vent door cable.
