Controls and Operating
3-22
Heater
The blower control (3) is rotated to select one of three blower speeds. Air
direction can be adjusted by turning the direction controls (4 and 5).
The temperature control (1) is rotated to vary the heater output
temperature. Heater output air is unheated with the control turned fully
anticlockwise and heated by turning clockwise.
Heater/air conditioner outlets (6) may be adjusted to control the air flow
output by opening and closing the control flaps. Air direction can be
adjusted by rotating the complete outlet.
Air Conditioner
Keep all windows and vents closed.
Blower control (3) is rotated to select one of three blower speeds. The air
conditioning will not operate if the blower control is not switched on. Air
direction can be adjusted by turning the direction controls (4 and 5).
Turning control (2) to the right switches on the air conditioning. The air
conditioner output temperature can be controlled using the temperature
control (1).
The heater/air conditioner outlets (6) may be adjusted to control the air
flow output by opening and closing the control flaps. Air direction can be
adjusted by rotating the complete outlet.
NOTICE:
When the air conditioning is switched on, the engine cooling fan
automatically engages.
Air Condition Commissioning Procedure
If the machine has been idle overnight or for an extended period of time,
the refrigerant in the air conditioning unit converts from a gas to a liquid.
This puts the compressor unit under a great deal of strain trying to
compress a liquid instead of a gas, and could cause a failure of the air
conditioning unit.The following commissioning procedure allows the air
conditioning unit to achieve normal operating parameters.
1. Start the machine and allow it to run until the engine is at a normal
operating temperature of 80°C (176°F).
2. Turn the blower control to setting 1.
3. Turn on the air conditioning unit on for 5 seconds then off for
5 seconds.
4. Repeatedly switch the air conditioning on and off for at least 1 minute.
This should be at least 12 repetitions.
5. Commissioning the air conditioning unit is complete and ready for use.
NOTICE:
Follow the instructions given above, otherwise the machine may
be damaged.
