Cab Climate Control Panel
The climate control panel allows the driver to control
the heating, ventilating, defrosting, and air condition-
ing (A/C) functions. See
Fig. 6.1 . The cab climate
control panel has three knobs to control the functions
of the cab temperature system:
•
fan control knob
•
air selection knob
•
temperature control knob
The climate control panel may also be equipped with
up to three rocker switches to control recirculation,
air conditioning, and bunk override.
All of the dash-face outlets have adjustable louvers
that pivot right and left, and up and down. The out-
lets can be closed by moving the louvers all the way
down. Windshield defrost outlets and the passenger’s
door window defrost outlet have non-adjustable lou-
vers. The bunk outlet (at the right-hand rear corner of
the bunk) has two sets of vertical louvers that oper-
ate like the horizontal dash-face louvers.
Fan Control Knob
The fan control knob activates the fan, which forces
fresh air or recirculated air through the air outlets.
The fan control knob has eight fan speed settings
and an OFF position.
To operate the fan knob, turn knob clockwise to in-
crease airflow, or counterclockwise to decrease air-
flow.
Temperature Control Knob
The temperature control knob is used to select the
desired temperature in the cab. Turn the knob coun-
terclockwise for cool air, or clockwise for hot air.
Air Selection Knob
The air selection knob allows the driver to control the
flow of air through the face outlets, the floor outlets,
the defrost (windshield) outlets, or a combination of
these outlets.
•
Air Conditioning Mode: Cools and dehumidifies
the air inside the cab
•
Face Mode: Directs all airflow through the face
or instrument panel outlets.
•
Bi-Level Mode: Directs the airflow equally to
the face outlets and the floor outlets.
•
Floor Mode: Directs all airflow through the floor
outlets.
•
Floor/Defrost Mode: Directs the airflow equally
to the floor outlets and the defrost outlets.
•
Defrost Mode: Directs all airflow through the
defrost outlets.
IMPORTANT: Operate the air conditioner at
least five minutes each month, even during cool
weather. This helps prevent drying and cracking
of tubing seals, reducing refrigerant leaks in the
system.
NOTE: Shutting off the heater supply gate valve
(if equipped) on the engine limits the ability to
control air conditioning temperature in the cab
and in the sleeper. With the valve shut off, warm
coolant is no longer available from the engine,
and the outlet air temperature controls can’t be
used to change air temperature.
Recirculation Switch
When the recirculation switch is activated, the HVAC
system limits the amount of outside air that enters
the cab. Activate the recirculation switch to prevent
dusty or smoky air from entering the cab. Recircula-
tion mode can also decrease the time required to
cool or heat the cab interior during extreme outside
temperature conditions. When the recirculation mode
