Peterbilt 379 Installation Guidelines

INSTALLING THE RETURN AIR VENT

The supplied return air vent(s) should be installed under the bunk, in the same area where the CHEB will be mounted. Your package may contain either one large grill with a mounting frame or two smaller 12.5" x 5.5" surface-mount grills. We suggest using a hole saw and reciprocating saw to cut out the hole for the large grill. If you received the two 12.5" x 5.5" grills instead of the one large grill, use a 4" hole saw to cut at least two holes behind each grill. Use of the recip- rocating saw is optional for those grills (Figs. 6-8).

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.
