Localized stains caused by accidental spillage may be one of three types:
0 Water based stainscaused byfoodstuffs,starches, sugars, soft drinks,fruit stains, washable inketc. These stains
adhere readily to the pile and do not respond to vacuum cleaning. They are best removed immediately using
the procedure detailed below.
0 Oil /grease based stains caused by spillage or other contamination by butter, grease, hand cream, ball point pen
ink, crayon, lipstick etc.
0 A combination of both these types.
Spot Cleaning - Localized Stains
To remove water based stains:
. Blot up liquids and /or scrape off semi-solids using a spatula.
. Sponge the affected area with clean luke-warm water. Use a clean, damp, undyed, cotton cloth to absorb as much

= Rinse with clean, warm water, taking care not to over-wet the carpet.
Absorb excess moisture by laying dry, undyed cloths or white paper towels over the moist carpet under light pres-
. When the carpet is thoroughly dry, vacuum clean the area to lift the carpet pile.
CAUTION: When liquids are applied to the pile, use only a clean cloth or sponge. Do not apply liquids directly to the

sure; replace when necessary.
To remove oil /grease based stains:
. Using a suitable aerosol containing solvent loaded with absorbent powder, spray the affected areas of the carpet.
= Allow the solvent to evaporate and remove the powder containing the grease by using a vacuum cleaner or brush.
m:
CAUTION: Solvents must only be used in well-ventilated areas where naked lights and smoking are prohibited.
The solvent loosens the grease from the fibre and the powder then absorbs the grease-carrying solvent.
Neat solvent, eg dry cleaning
fluid, may be used, but should be used sparingly from a clean white cloth.
To remove stains which are a combination of oil and water based contamination (usually resulting from food or drink):
. Treat combination stains as for water based stains.
. Allow to dry out.
. Treat as for grease based stains.

13.7.6 Repair of Damaged Carpet
The most common cause of accidental damage to carpets is cigarette burns (especially to polypropylene carpet).
These can be repaired easily on new carpets by cutting out the face material in the affected area and replacing with new face material with a latex locking coat of approximately 100g/m2 dry then incorporating a P.S.A.B. (pressure sensi- tive adhesive backing) which would be applied to roll carpet in the form of a laminate film at Firth Furnishings subsidi- ary Textile Bonding, Higham Ferrers, Northampton, UK.
The
film has a peelable release paper, which means that the new material would simply be cut to size, the release paper
removed and then the new carpet pressed into position.
The problem
in replacing areas in old or soiled carpets is that the replacement of damaged areas with new carpet would
create a visual difference, ie un-worn pile, clean appearance, which would then cause the repaired area to stand out
from the rest of the carpet. The only answer would be to abrade the rest of the new carpet to the same degree as the
old carpet.

0 Because HFC 134A is fully recycleable it may be 'cleaned' by the recovery equipment and re-used following
removal from a system.
0 Leak tests should only be carried out with an electronic analyzer which is dedicated to HFC 134A. Never use a CFC 12 analyzer or naked flame type.
0 Do not attempt to 'guess' the amount of refrigerant in a system, always recover and recharge with the correct
charge weight. In this context do not depress the charge or discharge port valves to check for the presence of
refrigerant.
14.1.3 Handling Lubricating Oil
0 Avoid breathing lubricant mist, it may cause irritation to your respiratory system.
0 Always decant fresh oil from a sealed container and do not leave oil exposed to the atmosphere for any reason
other than to fill or empty a system. PAG oil is very hygroscopic (absorbs water) and will rapidly become con-
taminated by atmospheric moisture.
PAG oil is
NOTcompatible with previously used mineral based oils and must NEVER be mixed (Fig. 1). Do not
re
-use oil when it has been separated from refrigerant, following a recovery cycle. Dispose of used oil safely.
14.1.4 System Maintenance
0 When depressurizing a system do not vent
refrigerant directlyto atmosphere, always use Jaguar
approved recovery equipment.
0 Always decant compressor oil from a sealed con- tainer and do not leave oil exposed to the atmosphere
for any reason other than to fill or empty
a system.
PAG oil is very hygroscopic and will rapidly become
contaminated by atmospheric moisture.
0 Plug pipes and units immediately after disconnection
and only unplug immediately priorto connection. Do
not leave the system open to atmosphere.
0 It is not necessary to renew the receiver drier when- ever the system has been 'opened' as previously ad-
vised - see note this page. However,if a unit or part
of the system is left open for more than five minutes,
it may be advisable to renew the receiver drier. This
guidance is based on
U.K average humidity levels;
therefore, locations with lower humidity will be less
critical to moisturecontamination of the unit.
It must
be stressed that there is not
a 'safe' period for workto
be carried out in: ALWAYS plug pipes and units im-
mediately after disconnection and only remove plugs
immediately prior to connection.
J82-387
Fin. 1
U: The receiver / drier MUST be renewed if the compressor has failed or if it is suspected that debris may be in
the system.
0 If replacement parts are supplied without transit plugs and seals DO NOT use the parts. Return them to your
supplier.
0 Diagnostic equipment for pressure, mass and volume should be calibrated regularly and certified by a third
party organization.
0 Use extreme care when handling and securing aluminium fittings, always use a backing spanner and take
special care when handling the evaporator.
0 Use only the correct or recommended tools for the job and apply the manufacturer's torque specifications.

0 14.9 GENERAL SYSTEM PROCEDURES
14.9.1 Leak Test
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. When checking for non visible leaks use only
a dedicated HFC 134A electronic analyzer
and apply the probe all round the joint / connection.
Should a leak betraced to a joint,checkthatthefixing issecuredtothecorrecttightening torque before any other action
is taken.
Do not forget to check the compressor shaft seal and evaporator.
CAUTION : Never use a dedicated CFC 12 or naked flame type analyzer.
14.9.2 Charge Recovery (System depressurization)
The process of HFC 134A recovery will depend on the basic characteristics of your chosen recovery/ recycle I recharge
equipment, therefore, follow the manufacturer's instructions carefully.
Remember that compressor oil may be drawn
out of the system by this process, take note of the quantity recovered
so that it may be replaced.
CAUTION: Observe all relevant safety requirements.
Wear suitable eye and skin protection
Do not mix HFC 134A with CFC 12. Do not vent refrigerant directly to atmosphere and always use Jaguar approved recovery I recycle I re- charge equipment.
Take note of the amount of recovered refrigerant, it will indicate the state of the system. 0
14.9.3 Evacuating the System
This process, the removal of unwanted air and moisture, is critical to the correct operation of the air conditioning sys-
tem. The specific procedures will vary depending on the individual characteristics of your chosen recovery I recycle / recharge equipment and must be carried out exactly in accordance with the manufacturers instructions. However,
it is recommended that the initially only the HIGH side valve be opened at the start of the procedure. 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 evacu- ation process completed. If a vacuum is not registered on the LOW side it may indicate that the expansion valve is
jammed closed or that the system is blocked. This simple check may save time and effort when the system is re- charged.
Moisture can be highly destructive and may cause internal blockages due to freezing, but more importantly, water sus- pended in the PAG oil will damage the compressor. Once the system has been opened for repairs, or the refrigerant
charge recovered, all traces of moisture MUST be removed before recharging.
14.9.4
The amount of oil drawn out during a recovery procedure will be dependent on the state of the system and the rate
of recovery. The quantity will be approximately 30 to 40 ml; this may vary, and the figure is given only for guidance.
The oil separator vessel in the recovery equipment must be clean and empty
at the start of the process so that the quan- tity of oil which is drawn out may be accurately measured.
Oil may be added by three methods,
1 and 2 being direct into the system and 3 with the compressor off the vehicle;
1. Via the recovery I recycle 1 recharge station.
2. Proprietary oil injector.
Adding Lubricating Oil - Compressor Related
1ynfa: Equipment manufacturer's instructions must be adhered to when using direct oil introduction.
3. Directly into the original, or new unit, because of rectification work to the existing compressor, or the need to fit a new compressor.
Original
From an existing compressor, drain the oil into a measuring cylinder and record the amount. Flush the unit out
with fresh PAG oil and drain thoroughly, Replenish the compressor with the same amount of PAG oil that was
originally drained out and immediately plug all orifices ready for refitting to the vehicle.
