Attaching The Drain Hose; Installing The Return Air Grill - Dometic Kohler 7APU Operation And Installation

Attaching The Drain Hose

Climb under the sleeper with the length of 5/8" diameter
hose and the small hose clamp. Secure the hose to the hose
barb with the clamp. Secure the hose to something under the
sleeper that is fixed. Fashion the hose such that is forms a
trap, such as a plumber's running trap. The trap will help
keep fumes and bugs out by providing a water seal.

Installing the Return Air Grill

Install the return air grill so that the path between the grill
and the coil face of the unit is open and unrestricted. The
path should not be any smaller in square inch area than the
size of the coil face. Place the grill so that it will not be
covered up by cargo, sheets, boxes, etc.
