b. Air Conditioning Unit The air conditioning unit (5) cools end ventilates the ambulance
patient compartment. It is mounted on the front wall of the patient compartment, and is designed
to provide a section between cooling and recirculating inside air and cooling outside air. The inside
air section is used when maximum cooling is required under conditions of high temperature and
humidity. The outside air is used for most air conditioning situations and for vent mode. Fan speed
end temperature may be varied as required.
c. Personnal Heater. Because the heater in the cab is not sufficient to heat the patient
compartment, e personnel heater is provided within the patiant compartment. It produces heat by
burning a mixture of fuel and air in a stainless steel heat exchanger and burner assembly. The heater
is designed to bum fuel from the trucks fuel tank. It can be manually controlled from a control unit
(6) located at the base of the lower litter berth on the right side of the patient compartment.
d. Domelight and Focus Lights. There is a fluorescent domelight (2) over the canter aisle of
the patient compartment to provide light for medical purposes. When the service lights/blackout
toggle switch the ‘“BLACKOUT” position and the rear doors or door between the cab and patient
compartment is open. the domelight goes off and a blackout light (3) comes on. When more light
is needed, four focus lights (1) (two on each wall) can be used. The lights can be pulled from thair
wall mounts and mounted in any of six mounting blocks, or they can be hand held if needed.
1-18. TRUCK LOADING
a. Proper loading of the truck is governed by weight limits and load distribution. The trucks
era rated in tame of Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Rating (GAWR).
These ratings are beead upon the weekest component in the suspension system (axles, springs, tires,
or wheels.
(1) Gross Vehicle Weight Rating (GVWR). The Gross Vehicle Waight Rating (GVWR) is
the maximum allowable loaded weight of the truck, driver, passenger(s), and payload,
measured in pounds. Tha rating takes into account the capabilities of the engine,
trarsmission, frame, springs, brakes, axles, and tires.
(2) Gross Axle Welght Rating (GAWR). The maximum load that can be put on front and
rear axles.
b. A certification Iabel, located on the trailing edge of the operator’s left-hand door, specifies
these ratings and shows the maximum waight that the front axle can carry (front GAWR) and tha
maximum weight that the rear axle can carry (rear GAWR).
C. The example below shows a fully loaded truck, tha maximum GVWR (1), tha front GAWR
(3), and the back GAWR (2).
Curb weight equals the weight of the truck without driver, passenger or cargo, but includes fuel and coolant.
