Installing the Plenum on the Front of the CHEB

Using a ¼" nutdriver, remove the plastic 5" or 7" oval hose adaptor. Find the 4"x 6" (or 4"x4") distribution plenum. Install the weather stripping on the contact surfaces and place over the hole on the unit. Reinstall the screws into the new plenum.

Installing the CHEB

Install the CHEB on the passenger side of the truck.

Locate the CHEB template (supplied with the unit) and position it with the “edge of the unit” 1-1½" from the factory HVAC unit mounting foot. The “edge of the

ENGLISH

unit” line with the notations for the quick connections should be nearest the bunk wall. The line of the “edge of the unit” should be approximately 5" from the bunk wall.

Mark for the two quick connect holes 3½" off the “edge of the unit” using the construction lines. Drill through the rubber mat with a 2½" hole saw (DO NOT DRILL THROUGH THE METAL). Then drill through the metal with a 1-7/8" holesaw.

Drill the drain hole with a 1-5/8" hole saw.

Drill for mounting brackets for the CHEB using the following recommnedations:
