Is the airflow blocked?
Closed or blocked vents and a dirty air filter
can hinder the efficiency of a heat pump.
• Be sure ceiling vents are open to distribute
heat pump output air. Also make sure furni-
ture, clothing items, packages or other
obstructions do not block the air return air
grilles beneath the rear bed.
• The air conditioner filter should be checked
monthly for dirt build-up and replaced as
needed. The air filter is a disposable woven
fiberglass type, which cannot be cleaned and
should be replaced when coated with dust.
See Air Conditioner Filter for location and
instructions.

SYSTEM
NOTE: See "Electronic Thermostat" for instruc-
tions on turning the air conditioner on

The central air conditioner is mounted in an
exterior compartment on the left (driver) side of
the coach. (See page 0-4.) The compartment door
APPLIANCES & INTERIOR FEATURES
opens for easy maintenance and periodic service.

through ducts in the ceiling of the coach. Inside
air returns to the air conditioner through a filter
system beneath the rear bed. (See "Air Condi-
tioner Filters".)

which is hinged near the head of the mat-
tress. It is supported by gas props while
open.
• Lift the filter out of the bracket assembly
beneath the access panel.
• Place the new filter into the bracket, being
careful to observe airflow markings on the
TM
edge of the filter.
