■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.

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.

2. Remove shipping tape from vent door. See Figure 7.

Failure to remove shipping tape will prevent fresh air vent door from opening and may result in dam- age to the vent door cable.

3.Lift chassis level with wall sleeve.

4.Slide chassis into wall sleeve until foam gaskets rest firmly against front of wall sleeve.

5.Screw chassis to wall sleeve with four 13/4-in. long 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.
