GENERAL INFORMATION

Air conditioning system precautions

General
The air conditioning system contains fluids and 
components which  could be potentially hazardous to 
the service engineer or the environment if  not 
serviced and handled correctly. The following 
guidelines are intended to  alert the service engineer 
to potential sources of danger and emphasise the  
importance of ensuring the integrity of the Air 
Conditioning operating  conditions and components 
fitted to the vehicle.

Where necessary, additional specific precautions are 
detailed in the relevant sections of this Manual which 
should be referred to prior to commencing repair 
operations.

The refrigerant used in the air conditioning system is 
HFC-134a  (Hydrofluorocarbon) R134a. Always 
adhere to the following precautions:

WARNING: Servicing must only be carried out by 
personnel familiar with both the vehicle system 
and the charging and testing equipment. All 
operations must be carried out in a well 
ventilated area away from open flame and heat 
sources.

WARNING: Do not allow a refrigerant container to 
be heated by direct flame or to be placed near 
any heating appliance. A refrigerant container 
must not be heated above 50 

°

C.

Do not leave a container of refrigerant without its 
cap fitted. Do not transport a container of 
refrigerant that is unrestrained, especially in the 
boot of a car.

WARNING: Do not smoke or weld in areas where 
R134a is in use. Inhalation of concentrations of 
vapour can cause dizziness, disorientation, 
incoordination, narcosis, nausea or vomiting.

R134a is odourless and colourless. Do not 
handle or discharge in an enclosed area, or any 
area where the vapour and liquid can come in 
contact with a naked flame or hot metal. R134a is 
not flammable but can cause a highly toxic gas.

WARNING: Do not allow fluids other than R134a 
or compressor lubricant to enter the air 
conditioning system. Spontaneous combustion 
may occur.

WARNING: R134a is a hazardous liquid and when 
handled incorrectly can cause serious injury. 
Suitable protective clothing, consisting of face 
protection, heat proof gloves, rubber boots and 
rubber apron or waterproof overalls, must be 
worn when carrying out operations on the air 
conditioning system.

WARNING: Due to its low evaporating 
temperature, R134a must be handled with care. 
R134a splashed on any part of the body will 
cause immediate freezing of that area. Also, 
refrigerant cylinders and replenishment trolleys 
when discharging will freeze skin to them if 
contact is made.

WARNING: Under no circumstances should 
refrigerant hoses be disconnected without first 
discharging the system.

Do not disconnect any pipes in an air 
conditioning refrigeration system unless trained 
and instructed to do so. A refrigerant is used 
which can cause blindness if allowed to contact 
eyes.

WARNING: Refrigerant must always be recycled 
before re-use to ensure that the purity of the 
refrigerant is high enough for safe use in the air 
conditioning system.

Recycling should always be carried out with 
equipment which is design certified by 
Underwriter Laboratory Inc. for compliance with 
SAE J1991. Other equipment may not recycle 
refrigerant to the required level of purity.

A R134a Refrigerant Recovery Recycling 
Recharging Station must not be used with any 
other type of refrigerant.

Refrigerant R134a from domestic and 
commercial sources must not be used in motor 
vehicle air conditioning systems.
