formation - Climate Control System
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.
