■INSTALL CHASSIS IN SLEEVE (See Figures 11 to

13)

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 lb. For personal protection, seek help when lifting the unit. Lift unit by holding unit basepan.

2.If retrofitting into a GE, Amana, Trane, or Friedrich wall sleeve/grille, remove any existing foam seals from competitive manufacturer’s grille before installing unit.

3.Remove shipping tape from vent door. See Figure 11.

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

4.Carefully remove power cord packing material and discard.

5.Lift chassis level with wall sleeve.

6.Slide chassis into wall sleeve until foam gaskets rest firmly against front of wall sleeve. See Figure 12.

7.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. For Carrier wall sleeves, use the top-most and bottom-most screw holes. For competitive wall sleeves, line up the correct attachment holes on the chassis with the holes in the sleeves. See Figure 13.
