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: 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.

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.
