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),



Scenario C:

- drain for the first time (note down the value),

- wait 2 hours ,



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.

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.

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.

105944

Note:

Use an adjustable mirror wherever access is diffi-cult.

WARNING

After the dye has been used in the refrigerantfluid, it is essential that the reason for using thedye and the date of the operation are marked ona label (provided with the dye capsule). The labelmust be placed near the cold loop filling valves(shock absorber turret) where it is visible.

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.
