AIR CONDITIONING AND HEATING SYSTEM CONTINUED
Heater Coil
00012
The heater coil is a device that is similar to a radiator. The heater coil heats the cab of the machine. The heater coil
is exposed to the air which passes across the evaporator coil. The heater transfers the heat from the hot engine
coolant into the air that is traveling across the heater coil. The heat transfer will heat up the air that is flowing to the
cab, which also reduces the temperature of the coolant that is flowing back to the engine cylinder.
Water Valve
00012
The water valve is a device that is used to regulate the flow of engine coolant to the heater coil and the flow of
engine coolant from the heater coil.
The water valve is connected to a mechanical cable. The mechanical cable is connected between the control knob
in the cab and the water valve. The control knob opens the valve and the control knob closes the valve.
