Fresh/Recirculation Air Switch - Kenworth Y53-1024 Operator's Manual

Fresh/recirculation Air Switch

The Fresh/Recirculation Air Switch is the rightmost switch on the Sleeper Control
Panel. The two-position switch controls the source of the incoming air to the air
conditioning and ventilation system. With the switch in the FRESH position (Top
position pressed) outside air is introduced to the air conditioning or ventilation
system. In the RECIRCULATION position (Bottom position pressed) sleeper air
is recirculated through the system.
The system can be operated in a ventilation only mode by placing the Air
Conditioning/Heating Switch in the OFF position and moving the Fan Con-
trol Dial from the OFF position. With the Fresh/Recirculation Switch in the
FRESH position, outside air is vented to the sleeper compartment.

NOTE: The Fresh/Recirculation Switch is only opera-
tional when the Fan Control Dial is in the ON position.
When the Fan Control Dial is in the OFF position, the
Fresh/Recirculation door and control will be deacti-
vated. The Fresh/Recirculation door will remain in the
position (open or closed) selected prior to turning the
blower OFF.
