Air Conditioning System

Heating, Ventilation & Air
Conditioning Operation
The air conditioning circuit operates by the
pressuriser fan drawing clean air into the cabin
through the carbon filter. This fan pressurises the
cabin with clean air and forces air out any holes or
leaking seals in the cabin ensuring no impurities can
be drawn into the operator's clean environment.
The blower fan then pulls air through the air
conditioning evaporator and heating evaporator
and pushes it to the demist and roof vents. If the
air conditioning compressor is engaged the air
conditioner evaporator will cool the air as it is drawn
though it. If the heater thermostat is turned to heat,
the air will warm again as it passes through. If the
heater is off, the cool air passes through to the vents.
Compressor
The air conditioning compressor is located on
the front side of the engine. This compressor is
connected to the engine by a v-belt. The compressor
is engaged when ever the cabin blower fan switch
is energised. The thermostat will cycle the air
compressor if the evaporator gets to cold.
Condensor
The air conditioning system condenser is located in
front of the engine radiator. The condenser is cooled
by air being drawn through from the engine fan. The
condenser requires regular cleaning of dust and any
debris.
NOTE: Take care not to damage the condenser coils
or fins when cleaning the condenser.

Receiver Dryer
The air conditioning receiver dryer is fitted to
the right hand chassis rail under the cabin. This
component captures any moisture that is circulating
in the air condition system. Moisture in the air
conditioning system freezes and causes blockages.
The component must be replaced any time the air
conditioning system is opened or serviced.
Heating System
Coolant from the engine flows through the heater
core causing it to radiate heat into the cabin when
the engine is up to temperature. The volume of the
water travelling through the system, and therefore
the amount of heat transferred, may be adjusted by
setting the temperature on the A/C head unit.
To enable the heating core to be isolated from the
engine two taps have been installed. The first tap is
located on the right hand side of the engine behind
the radiator. The second tap is located at the header
tank.
NOTE: If the heating is not working when the engine
is warm, ensure that the isolating taps are allowing
coolant to flow through to the heater core.
