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.
DUCTED ROOF AIR
CONDITIONING SYSTEM
The furnace thermostat also controls ducted
roof air conditioner operation when the
thermostat switch is placed in "cool" position.
All cooling functions controlling to setpoint
have a short cycle protection time delay of 3
minutes. There will be no delay if the cycle OFF
time exceeds 3 minutes.

NOTE: The ducted roof air conditioning system
has ceiling registers that can be closed if
necessary to force more cool air toward
a specific area of the coach or to route
cool air away from a specific area. If too
many vents are closed, however, it can
cause the air conditioner unit to shut
down, particularly in high humidity
conditions.
