Description an
d Operation
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 o
f, and comply with al
l 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 ex ceed, the requirements detailed in the Specification sub-
section.
Handling Refrigerant

We
ar eye protection at all times. Use gloves and keep all
skin covered that may come into contact with refrigerant.
Should refrigerant come into co ntact 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 comp ressed air to flush out a system. Under certain ci rcumstances a combination
of HFC 134A refrigerant, compressed air and a source of combus tion (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 neve r 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 atmo sphere; always use Jaguar approved recove ry equipment. Never depress the charge
or discharge port valves to check for the pr esence 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 ANALYZ
ER 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 Lubricati
ng Oil
Av
oid breathing lubricant mist; it can cau
s
e irritation to the respiratory system.
Always use fresh oil from a sealed containe r and do not leave oil exposed to the atmosphere for any reason other than to fill
or empty a system. PAG oil is very hygr oscopic (absorbs water) and will rapidly become contaminated by atmospheric
moisture.

PAG oil is NOT compatible with previously used mineral based oi ls and must NEVER be mixed. Do not re-use oil when it has
been separated from refrigerant, following a re covery cycle. Dispose of used oil safely.
System Maintenance
Plug pipes an
d units immediatel
y after disconnection an d 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 susp ected that debris may be present in the
system.
It is not always necessary to renew th e receiver drier if the correct procedur es 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; lo cations with lower humidity levels will be less critical to
moisture contamination. It must be stressed however th at there is not a safe period for work to be carried out in.
Do not use any replacement parts su pplied without transit plugs and seals - return them to the supplier.
Diagnostic equipment for pres sure, mass and volume should be calibrated regularly and certified by a third party
organization.
Use extreme care when handling and securi ng aluminum fittings; always use a backing spanner and take special care when
handling the evaporator.
Use only the correct or re commended tools for the job and apply the manufacturer's torque specifications.
