Air Conditioning (A/C) System (12.03)
Climate Control (12.00)
May 2007 Workshop Manual 12-3-3
The A/C unit houses the evaporator, heater matrix and air
flow flaps.
The unit also incorporates two servo motor operated air
distribution flaps.
1. Regulates airflow to the cabin vents.
2. Regulates airflow to the defrost / demist air ducting.
When the cabin air flap is open, air is ducted to the cabin via
face and foot level air vents.
Condensate (water) which forms on the evaporator fins is
drained out of the unit case through a drain hose, located at
underneath / rear of the evaporator.
Refrigerant System

Warning
Do not perform a pressure test or leak test for R-134a service equipment and or vehicle A/C using
compressed air. Some mixtures of air and R-134a have
been shown to be combustible at elevated pressures.
These mixtures, if ignited, ma y cause injury or property
damage. Additional health and safety information may
be obtained from refrigerant manufacturers.
Warning
Do not allow refrigerant to leak near a fire or any kind of heat. A poisonous gas may be generated if
refrigerant gas contacts fire or heat such as from
cigarettes and heaters. When carrying out any
operation that can cause refr igerant leakage, extinguish
or remove the above mentioned heat sources and
maintain adequate ventilation.
Warning
Handling liquid refrigerant is dangerous. A drop of
refrigerant on the skin can result in localized frostbite. When handling refrigerant, wear gloves and safety
goggles. If refrigerant sp lashes into the eyes,
immediately wash them with clean water and consult a doctor.
Warning
Avoid breathing A/C refrigerant or lubricant vapor.
Exposure may irritate eyes, nose and throat. Also, due
to environmental concerns , Aston Martin recommend
the use of a recovery/recycling/recharging unit when
draining R-134a from the A/C system. If accidental A/C
system discharge occurs, vent ilate the work area before
resuming service.

May 2007 Workshop Manual 12-3-9
Maintenance
Assessment of the A/C system operating efficiency and fault
classification may be achieved by using the facilities on a
Recovery / Recycling / Recharging unit.
Follow the manufacturer's instructions implicitly and observe
all safety considerations.
Connections
Only use hoses with connectors which are dedicated to
HFC 134a charge ports.
Recovery
Read manufacture’s instructions and warnings before
completing any recovery / evacuating and charging
operations.
Warning
Under no circumstances should connections be made with the A/C system in operation or valves open. Should valves be open and a vacuum pump or
refrigerant container attached, an explosion could
occur as a result of high pressure refrigerant being forced back into the vacuum pump or container.
Warning
Handling liquid refrigerant is dangerous. A drop of
refrigerant on the skin can result in localized frostbite. When handling refrigerant, wear gloves and safety
goggles. If refrigerant sp lashes into the eyes,
immediately wash them with clean water and consult a doctor.
Caution
Do not attempt to adapt this unit for R-12 as an A/C
system failure will result. Recovery / Recycle /
Recharging equipment has sp ecial connections to avoid
cross contamination wi th R-12 systems.
The A/C unit’s overfill li mitation mechanism has been
calibrated specifically for use with the 50 lb. (23 Kg)
refillable refrigerant tank.
Run the A/C system for a few minutes before starting the
recovery procedure as this wil l enable more refrigerant to
be recovered. Turn the A/C system off before starting the
procedure.
Ensure the A/C system has pre ssure in it before beginning
the recovery process; if there is no system pressure there is
no refrigerant to recover.
Ensure that the oil drain valve is closed.
Caution
The Recovery / Recycling / Re charging unit relies on a
weighing mechanism to weight the quantity of oil
removed. Ensure that the Recovery / Recycle /
Recharging unit is not disturbed during the recovery procedure.

12-3-10 Workshop Manual May 2007
1. Connect an R-134a Recovery / Recycling / Recharging
unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to evacuate the A/C system.
Evacuation
The removal of unwanted air and moisture, is critical to the
correct operation of the A/C system. Moisture in the system
can be highly destructive and may cause internal blockages
due to freezing; water suspended in the lubricating oil will
damage the compressor. Once the A/C system has been
dismantled, or the refrigerant charge recovered, all traces of
moisture must be removed before charging.
Read manufacture’s instruct ions and warnings before
completing any Recovery / Recycling / Recharging
operation.
1. Connect an R-134a Recovery / Recycling / Recharging unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to evacuate the A/C system.
Charging
Read manufacture’s instruct ions and warnings before
completing any Recovery / Recycling / Recharging
operation.
1. Connect an R-134a Recovery / Recycling / Recharging unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to charge the A/C system.
Compressor oil may be drawn ou
t during this process, take
note of the quantity recovered so that it may be replaced.
It is recommended that initiall y only the high-side valve be
opened at the start of the pr ocedure. After a short time a
small depression should be seen on the low-side, at which
point the low-side valve may be opened and the evacuation
process completed. If a vacuum is not registered on the
low-side, it may indicate that the expansion valve is
permanently closed or that th e system is blocked. This
simple check may save time and effort when the system is
recharged.
Caution
Do not exceed the specificat ion when charging the A/C
system with refrigerant. Doing so will decrease the
efficiency of the A/C unit or damage the refrigeration cycle parts.
Caution
Always start the charging of refrigerant from the high-
pressure side. If charging st arts from the low-pressure
side, vanes of the A/C compressor will not be released and abnormal noise may result.

4. Close all the vehicle doors and windows.
5. Measure the ambient temperature and high / low pressure side reading of Recovery / Recycling /
Recharging unit gauges.
6. Verify that the intersection of the pressure reading of the Recovery / Recycling / Recharging unit gauges and the
ambient temperature is in the shaded zone.
If there is any fault, inspect the refrigerant system according
to the troubleshooting chart.

8. Wait until the A/C output temperature stabilizes.
9. After the blower air is stabilized, read the dry-bulb
thermometer.
10. Verify the ambient temperature.
11. Verify the temperature is in the shaded zone.
If there is any fault, inspect the refrigerant system according
to the troubleshooting chart.
Vacuum Check
1. Stop the vacuum pump, note the high and low pressure side readings of the Recovery / Recycling / Recharging
unit gauges and wait for 5 min.
2. Check the high and low pressure side readings of the Recovery / Recycling / Recharging unit gauges.
1 If the readings have changed, inspect for leaks and go to Evacuation (Refer to ’E vacuation’, page 12-3-10).
2 If the readings have not changed, go to Charging (Refer to ’Charging’, page 12-3-10).
It is recommended th
at a free standing air mover is placed
in front of the conden ser / cooling system.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.
System Pressure Fault Classification
This table should be used in conjunction with the graphical representations of 'High side' pressure / ambient temperature
and 'Low side' pressure / evaporator temperature. Caution
Observe ALL safety precautions associ ated with ultraviolet equipment.
If erratic or unusual gauge movements occur, check the equipment against known Recovery / Recycling / Recharging unit
gauges.
