General Precautions

The refrigerant in the air conditioning system is HFC (Hydrofluorocarbon) R134a.


WARNING: R134a is a hazardous liquid and when handled incorrectly can cause serious injury. Suitable protective clothing must be worn when carrying out servicing operations on the air conditioning system.


WARNING: R134a is odorless colourless. Do not handle or discharge in an enclosed area, or in any area where the vapor or liquid can come in contact with naked flame or hot metal. R134a is not flammable but can form a highly toxic gas.


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


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


WARNING: 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: The refrigerant used in an air conditioning system must be reclaimed in accordance with the recommendations given with a Refrigerant Recovery Recycling Recharging Station.


NOTE: Suitable protective clothing comprises: Wrap around safety glasses or helmet, heatproof gloves, rubber apron or waterproof overalls and rubber boots.
