Vehicle Damage Warnings
CAUTION: Observe all relevant safety requirements. Wear suitable eye and skin protection Do not mix HFC 134A and CFC 12 refrigerants. Do not vent refrigerant directly to atmosphere and always use Jaguar approved recovery, recycle and recharge equipment. Note the amount of recovered refrigerant; it will indicate the state of the system.
Working Practices
Be aware of, and comply with all health and safety requirements, whether they be legislative or common sense. This applies to conditions set both for the operator and workshop.
Before commencing any repair or service procedure, disconnect the vehicle battery ground lead and protect the vehicle, where appropriate, from dirt or damage.
Work in a well ventilated, clean and tidy area.
keep all components and tools clean.
Recovery, recycle and recharge equipment must meet, or exceed, the requirements detailed in the Specification sub-section.
Handling Refrigerant
Wear eye protection at all times. Use gloves and keep all skin covered that may come into contact with refrigerant.
Should refrigerant come into contact with eyes or skin, wash the affected area with cool water and seek medical advice; do not attempt to treat the condition yourself.
Avoid breathing refrigerant vapor; it may cause irritation to the respiratory system.
CAUTION: Never use high pressure compressed air to flush out a system. Under certain circumstances a combination of HFC 134A refrigerant, compressed air and a source of combustion (welding and brazing operations in the vicinity), may result in an explosion and the release of potentially toxic compounds.
HFC 134A and CFC 12 refrigerants must never come into contact with each other. They will form an inseparable mixture which can only be disposed of by incineration.
Do not vent refrigerant directly to atmosphere; always use Jaguar approved recovery equipment. Never depress the charge or discharge port valves to check for the presence of refrigerant.
HFC 134A refrigerant is fully recycleable and it may be cleaned by the recovery equipment and therefore re-used following removal from a system.
WARNING: NEVER USE A CFC 12 ANALYZER OR NAKED FLAME TYPE.
Leak tests should be carried out with a UV spot lamp or an electronic analyzer which is dedicated to HFC 134A refrigerant.
Handling Lubricating Oil
Avoid breathing lubricant mist; it can cause irritation to the respiratory system.
Always use 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 contaminated by atmospheric moisture.
PAG oil is NOT compatible with previously used mineral based oils and must NEVER be mixed. Do not re-use oil when it has been separated from refrigerant, following a recovery cycle. Dispose of used oil safely.
System Maintenance
Plug pipes and units immediately after disconnection and do not remove the plugs until immediately before making the connection. Do not leave the system open to atmosphere.
The receiver drier must be renewed if the compressor has failed or if it is suspected that debris may be present in the system.
It is not always necessary to renew the receiver drier if the correct procedures have been followed. However, if a component or part of the system is left dismantled for more than five minutes, it may be advisable to renew the receiver drier. This guidance is based on UK average humidity levels; locations with lower humidity levels will be less critical to moisture contamination. It must be stressed however that there is not a safe period for work to be carried out in.
Do not use any replacement parts supplied without transit plugs and seals - return them to the supplier.
Diagnostic equipment for pressure, mass and volume should be calibrated regularly and certified by a third party organization.
Use extreme care when handling and securing aluminum fittings; always use a backing spanner and take special care when handling the evaporator.
Use only the correct or recommended tools for the job and apply the manufacturer's torque specifications.
