temperatures begin to reduce the efficiency of the
heat pump. The heat pump will not operate when
the outside temperature falls below 36 degrees F.
To operate the heat pump:
See the air conditioning/heat pump
manufacturer’s information in your InfoCase for
complete operating instructions.
Check your Air Filter
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.
•
The A/C return air filter should be checked
monthly for dirt build-up and cleaned or
replaced as needed. See “Air Conditioner
Filter” elsewhere in this section.
CENTRAL AIR CONDITIONER
NOTE: See “Electronic Thermostat” for
instructions on turning the air
conditioner on and changing the
temperature settings.
The central air conditioner is located behind
the louvered body panel on the right (passenger)
side of the coach. The panel can be opened for
maintenance and periodic service. (See
“Condenser Coils” elsewhere in this section.)
The cooled air is forced through ducts in the
ceiling of the coach. Inside air returns to the air
conditioner through a filter system in the rear
bedroom area of the coach. (See “Air Conditioner
Filter” elsewhere in this section.)
Condenser Coils
The condenser is located behind the louvered
body panel on the right side of the coach. The
condenser is the large, black, rectangular area
that looks like a car radiator. The panel is hinged
at the top edge to allow opening for periodic
cleaning or service. Remove the screws under the
lower edge of the panel and swing it upward for
access to the condenser.
Periodically sweep debris carefully from the
fins of the condenser. Rinse dust off with clean
water. The condenser coils must be clean and
free of dust, debris and insect particles, etc., for
the air conditioner to cool efficiently.
Further Information
See the air conditioner manufacturer’s
operating instructions supplied in your InfoCase.
They contain detailed operating instructions,
special precautions and basic troubleshooting.
AIR CONDITIONER FILTER
The disposable furnace-type filter must be
inspected monthly and replaced periodically so
the air conditioner will operate efficiently.
The air filter is woven fiberglass, which
cannot be cleaned and should be replaced when
coated with dust.
