Installation of Return Air Vents

The LG200 HVAC unit is capable of delivering approximately 278 cubic feet per
minute of cooled air. In order to supply the blower motor, a return air vent must
be installed if not already present. A 4 inch hole, or the equivalent in smaller
holes, is sufficient to supply the HVAC with return air from the sleeper. It is
common to port return air vents between the cabinets and the face of the bunk
as this leaves them less visible.
