AIR CONDITIONINGGeneral information 62A
INFORMATION ON THE FLUID
A label in the engine compartment details the specifi-cations of the refrigerant fluid (refer to the « Air condi-tioning - new R134a refrigerant » booklet ).
For retrieval, vacuum extraction and refilling theR134A gas, use only the high-pressure hose from thefilling station.
104112
Note:
- Plugs must be fitted to the disconnected air condi-tioning hoses to prevent moisture from enteringthe system.
- Do not remove the plugs from the replacementparts until last.
- Check for leaks, with the engine running and theair conditioning and blower at their maximum set-tings, during the five minutes following refilling.
- The instructions for adding oil ( (see 62A, Air con-ditioning) ) must be strictly adhered to when workis being carried out on the components of the airconditioning circuit.
- When replacing valves, the tightening torque mustbe adhered to strictly 0.8 daNm .
62A-2
AIR CONDITIONINGMaintenance 62A
Recommended annual operations:
- clean and blast the engine cooling condenser and ra-diator,
- to ensure that the cold air blower unit's condensedwater outlet is not blocked.
To check that the refrigerant system has been filled re-gularly, refer to the Warranty and Servicing booklet.
I - AIR CONDITIONING CONTROL ANTI-BACTERIAL CLEANER
Spray the entire aerosol of cleaner, fitted with a no-zzle, through the passenger compartment filter duct.
Leave to work for 15 minutes .
Operate the ventilation fan very slowly for 5 minutes.
Equipment required

WARNING
It is mandatory to follow the safety instructionswhilst working on the cold circuit( (see Safety ins-tructions)
.
Note:
Treat the air conditioning system with a specialcleaner after each winter period or extendedperiod of non-usage to prevent odour when thesystem is in operation.
WARNING
Spraying the cleaning product through the airinlet is strictly forbidden as it could damage theair conditioning blower.
62A-3
AIR CONDITIONINGMaintenance 62A
II - RECOVERING REFRIGERANT FLUID
There are three possible scenarios to consider when recovering refrigerant or checking the refrigerant load:
- the engine and air conditioning work (Scenario A),
- the engine works but not the air conditioning (Sce-nario B),
- neither the engine nor the air conditioning work(Scenario C).
Scenario A:
- Operate the air conditioning until the cooling fanassembly is triggered twice,
- turn the engine off,
- drain for the first time (note down the original va-lue),
- wait 15 minutes ,
- check that the relative pressure is no more than 0bar ,
- start the draining cycles again if the relative pressu-re is above 0 bar ,
- add together the values of the various drainingoperations, the load is confirmed as being correct ifthe amount of refrigerant is the specified load + 35g or - 100 g .
Scenario B:
- run the engine until the cooling fan assembly is trig-gered twice,
- turn the engine off,
- drain for the first time (note down the value),
- wait 15 minutes ,
- run the engine until the cooling fan assembly is trig-gered twice,
- drain for the second time (note down the value),
- start the draining cycles again if the relative pressu-re is above 0 bar ,
- add together the values of the various drainingoperations, the load is confirmed as being correct ifthe amount of refrigerant is the specified load + 35g or - 100 g .
Scenario C:
- drain for the first time (note down the value),
- wait 2 hours ,
- start the draining cycles again if the relative pressu-re is above 0 bar ,
- add together the values of the various drainingoperations, the load is confirmed as being correct ifthe amount of refrigerant is the specified load + 35g or - 100 g .
III - CREATION OF A VACUUM
It is essential to create a sound vacuum before loa-ding, otherwise the air conditioning will be faulty.
There are two scenarios to consider:
- the vacuum should be created immediately afterdraining (scenario A ),
- the creation of a vacuum should be carried out aftera delay of several hours or days (scenario B).
Scenario A:
- the creation of a vacuum lasts 20 minutes .
Scenario B:
- creating the vacuum takes 45 minutes to removeany residual moisture.
Test the sealing once the vacuum has been created(some stations do this automatically).
IV - FILLING
Top up the oil with the recommended type and quan-tity of oil, depending on the work carried out.
Refill the system.
Empty the pipes on the (filling station) .
Check that the system is operating correctly.
Check for leaks.
Note:
- The air conditioning circuit is fitted with a singlerefill valve, some filling equipment requires onlythe use of the high pressure pipe ( refer to thefilling station instructions ).
- Depending on the scenario, run the system fora few minutes before recovering the coolant toimprove drainage.
IMPORTANT
These procedures must be followed in order to avoid:
- gas escaping when the circuit is opened,
- damaging the environment by releasing gas intothe atmosphere when the circuit is opened orduring creation of a vacuum.

AIR CONDITIONINGSafety advice 62A
The specific gravity of refrigerant fluid is higher thanthat of air and it falls to the ground. This results in a riskof asphyxiation. Consequently, when working on thesystem ensure that there are no pits, wells, ventilationshafts, etc. any nearer than 5 m away, and start up thegas extraction equipment.
At temperatures above 100˚C , caused by a hot spotfor example, the refrigerant fluid decomposes and pro-duces a highly irritant gas.
It is possible to place components in the drying ovenafter painting or to carry out work near the system if thetemperature does not exceed 80˚C .
The correct routing of the pipes must be observed.
Ensure that the refrigerant piping is correctly fitted sothat it will not come into contact with metal parts in theengine compartment.
IMPORTANT
The following must be worn when handling refrige-rant fluid:
• gloves,
• protective eyewear (with side shields where possi-ble).
- In the event of refrigerant fluid coming into contactwith the eyes, rinse thoroughly with clean water for15 minutes .
- Keep eyewash available if possible.
- If refrigerant gets into your eyes, consult a doctorimmediately. Inform the doctor that the burns werecaused by refrigerant R134A .
- If the fluid comes into contact with other unprotec-ted parts of the body (even though the safety ins-tructions were followed), rinse thoroughly withclean water for 15 minutes .
IMPORTANT
- Any work involving refrigerant fluid must be carriedout in a well-ventilated area.
- The refrigerant must not be stored in a well, a pit,a hermetically sealed room, etc.
- Refrigerant fluids are colourless and odourless.
IMPORTANT
It is forbidden to carry out welding or brazing on:
- components of the air conditioning system whenthese are in place,
- the vehicle, due to the risk of overheating a com-ponent of the air conditioning system.
IMPORTANT
- Repairing any faulty components of the air condi-tioning system is strictly prohibited.
- All faulty components must be replaced.
IMPORTANT
Smoking is strictly prohibited in the vicinity of arefrigerant fluid circuit.

AIR CONDITIONINGCoolant circuit check 62A
Leak screening table
There are two types of device for detecting leaks:
- electronic sensors,
- tracer detectors.
I - ELECTRONIC DETECTORS
This device is used to measure variations in thequantity of refrigerant in the air: it emits an audiblesignal depending on the extent of the variation.
The device must be initialised before the check is carried out. To do this:
- immobilise the device,
- calibrate the device at one point in the compart-ment.
This point then acts as a scale for detecting rates ofcontamination.
This device is highly sensitive: when a leak is detec-ted, only follow the line of the circuit as closely aspossible to limit variations due to other gases.
This device only detects relatively substantial leaks.
II - TRACER DETECTORS
Leak detection by tracer involves adding a dye to therefrigerant and locating the points where fluid isbeing lost using an ultraviolet light.
Component Detection area Part to be replaced
after first check
Part to be replaced after
filling and second check
Condenser Inlet or outlet Pipes Condenser
Evaporator Connection bracket Pipes Connection bracket and/or evaporator
Compressor Inlet or outlet Pipes Compressor
Dehydrationcanister
Inlet or outlet Pipes Dehydration canister
Note:
Use the electronic detector and then the tracerdetector to check for leaks.
WARNING
Always refer to user instructions for the devicebefore carrying out any work.
WARNING
Make sure that the sensor at the end of the rod iskept extremely clean and in good condition.
IMPORTANT
Safety instructions must be followed when wor-king on the air conditioning circuit (see 62A, Airconditioning, Safety advice, page 62A-7) .
WARNING
The procedure described must be followed.
Note:
This leak-detection procedure should only beused as a last resor t for « leaks that cannot befound » .
62A-11
AIR CONDITIONINGCoolant circuit check 62A
The refrigerant fluid leak-detection procedure isbased on the use of a dye available in the form of athrowaway capsule (1) : leak traces are revealedusing an ultraviolet light (2) .
The dye remains in the air conditioning system.
It is possible to check the condition of the cold loopusing an ultraviolet light without adding a new cap-sule.
If there is nothing to indicate that dye has been used previously (label, etc.):
- place a cloth,
- release a small jet of refrigerant through the twovalves,
- shine the ultraviolet light inside the valves,
- check for fluorescent traces.
Add a measure of detection dye if there are no fluo-rescent traces and a label.
Affix a label.
Record the date on which the dye was added.
1 - Adding dye to the circuit
Fit the system for adding the dye to the low-pressurevalve, and using union (3) for vehicles fitted with asingle valve.
Add the dye to the circuit.
Run the air conditioning for approximately 15 minu-tes .
2 - Leak-detection procedure
Carry out an initial check (with the engine stopped)by sweeping the circuit with an ultraviolet light.
Carefully clean the outside of the refrigerant circuit.
Run the air conditioning until the leak can be detec-ted (if no leak is detected, check the condition of theevaporator).
105944
WARNING
It is forbidden to introduce dye into the cold loopif fluorescent traces appear.

CLIMATE CONTROLOperating principle 62B
Only special features of climate control are describedin this section .
For sections not dealt with ( (see 62A, Air conditio-ning) ) and ( (see 62C, Manual air conditioning) ).
I - POWER MODULE
In automatic climate control, there are eight ventilationspeeds.
The fan assembly power module is controlled by a vol-tage modulated by the air conditioning computer.
This control voltage is always 12 V , it is the control si-gnal (square signal) which varies:
- the amplitude and frequency do not change,
- but the cyclic ratio changes.
II - FLAP CONTROL MOTORS
These motors are located in the climate control unit and act on different flaps to direct the flow according to certain criteria:
- the mixer motor (1) is used for mixing the hot and coldair,
- the distribution motor (2) directs the air flow into thepassenger compartment via the vents,
- the recirculation motor (3) allows the air in the pas-senger compartment to be reused by isolating it fromthe external air.

III - PASSENGER COMPARTMENT TEMPERATURE SENSOR
This sensor supplies information on the interior tempe-rature.
It is a negative temperature coefficient thermistor loca-ted behind the rear-view mirror.
IV - EXTERNAL TEMPERATURE SENSOR
It is a negative temperature thermistor located in the ri-ght-hand rear-view mirror.
V - INSOLATION SENSOR
This sensor informs the computer of the intensity of su-nlight to correct the air flow to the air vents.
It is located in the centre of the dashboard.
