Have you checked your air filter lately?
Closed or blocked vents and a dirty air filter
can hinder the efficiency of a heat pump. See Air
Conditioner Filter for location and instructions.
• 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 filter should be checked monthly for dirt
build-up and replaced as needed. The air fil-
ter is a disposable woven fiberglass type,
which cannot be cleaned and should be
replaced when coated with dust.
CENTRAL AIR CONDITIONER
NOTE: See "Electronic Thermostat" for instruc-
tions on turning the air conditioner on
and changing the thermostat settings.
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
opens for easy maintenance and periodic service.
(See "Condenser Coils") The cooled air is forced
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".)
Air Conditioner Filter (Coach model 36C)
The disposable furnace type filter is located in
a slide-in bracket inside the passenger side of the
rear bed cabinet. The filter must be inspected and
replaced periodically so the air conditioner will
operate efficiently.
APPLIANCES & INTERIOR FEATURES
To Replace the A/C Filter:
