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.

Storing Refrigerant
Handling Insufficient Refrigerant Level
Handling Compressor Oil
Refrigeration Cycle
Operation
1. The Compressor (1) dr aws low pressure, low
temperature, refrigerant vapour from the evaporator (5)
and compresses it, raising th e refrigerant pressure and
temperature.
2. This high pressure, hot, refrigerant vapour enters the condenser (2), where it is cooled by the flow of ambient
air and changes state into a cooler, high pressure liquid.
3. From the condenser, the liqu id passes into the receiver
drier (3) which has three functions:
• Removes moisture from the refrigerant using a desiccant
• Filters the refrigerant to remove system contaminants
• Stores the refrigerant to cope with varying system refrigerant demands
4. The filtered liquid refrigerant, still at high pressure, then enters the expansion valve (4). Here it passes through a
controlled orifice and emerges as an atomised liquid
spray. This has the effect of reducing the refrigerant
pressure and temperature. The cold refrigerant spray
now flows into the evaporator (5).
5. As refrigerant passes through the evaporator core, it cools the incoming airflow. Heat is absorbed by the
refrigerant, during this process and it once again changes
state, from an atomised cool liquid into a vapour. The
refrigerant vapour then returns to the compressor for the
cycle to be repeated.
An automatic safety valve is incorporated in the compressor,
which will open if the system pressure rises above 41 bar.
The valve will reseat when the pressure drops below 27,6
bar. When the safety valve is open, the compressor will 'free
Warning
The refrigerant container is highly pressurized. If it is subjected to high heat, it could explode, scattering metal fragments and liquid refrigerant that can
seriously injure personnel. Store refrigerant at
temperatures below 40
oC (104 oF).
Caution
If an insufficient refrigerant level is detected while
troubleshooting, do not char ge (add) the refrigerant.
Because an accurate amount of refrigerant cannot be
determined from the pressure indicated on the
recovery / recycling / rechar ging unit, never charge the
refrigerant.
Caution
If there is too much or to o little refrigerant from the
refilling, there may be secondary problems such as
damage to the refrigerant cycl e parts, or a decrease of
cooling performance. Therefore, if it is determined that the refrigerant level is insufficient, completely remove refrigerant from the refriger ant cycle and refill with
refrigerant to the specified amount.
Caution
Use only ND8 compressor oil for this vehicle. Using a PAG oil other than DENSO OIL8 compressor oil will damage the A/C compressor.
Caution
Do not spill the ND8 compressor oil on the vehicle. A drop of compressor oil on the vehicle surface can
damage the paint work. If oil gets on the vehicle, wipe it off immediately.
Caution
ND8 compressor oil has a high moisture absorption
efficiency. If moisture mixe s with the compressor oil,
the refrigerant system could be damaged. Ensure caps
are installed immediately afte r using the compressor oil
or removing refrigerant system parts to prevent moisture absorption.

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.

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.
