INSTALLING THE RETURN AIR VENT

The return air vent will be mounted under the bunk in the side panel on the passenger side. It will just fit between the panel supports on the backside of the kick panel.

(Note: if your return air kit has the two 12½" x 5½"grills instead of the single square grill, either use a 4" hole saw to cut at least two holes behind each grill or use a reciprocating saw to cut out the rectangular holes for these grills.)

Locate the supports and cutout for the grill. Use a hole saw to cut out the four corners (Fig. 8), and a reciprocating saw to complete the hole for the vent (Figs. 9-10).

Remember, good air flow from the return air grill to the CHEB evaporator coil is critical for your air conditioning system to perform correctly. Do not allow anything to block this air flow.
