Control Panel Outlet Locations
The heater control panel is located on the dash to the right of the instruments. The
indicated switches and levers control the motors and air outlets as shown.
The heater is located in the right front corner, forward of the entrance door. An
optional auxiliary unit is located under the driver's seat. Electrical switches and me-
chanical diffusers control the volume and direction of airflow. The main heater has
a three-speed control switch for manual low or high speed operation, and an ad-
ditional maximum output position for flash defrosting or extreme conditions. All the
air from the main heater blower is directed to defrosting when the main outlet and
foot warmer outlet are closed.
The Noise Suppression switch on the left side switch panel turns off all heaters
and radio to allow the driver to hear sounds outside the bus; for example, at a rail-
road crossing. When the switch is in the "on" position, neither the heater blowers nor
the radio will operate.
