Inside Return Air Vents

Air conditioner filters are located inside the
Return Air Vents throughout the ceiling of the
coach and must be inspected monthly and
cleaned periodically so the air conditioners will
operate efficiently.
Supply airflow comes from the vents located
on the driver side of the coach. Return Air Vents
are located on the passenger side of the coach. It
is the Return Air Vents in which the cleanable air
filters are installed.
It is recommended to use mild soap and warm
water to clean the air filters. When finished,
allow air filters to air dry.
NOTE: There are multiple Supply and Return
Vents throughout the coach. Therefore,
you must remember to remove each
separate air filter from each Return Air
Vent to clean.
