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

7. Allow station to recover refrigerant from 

system.

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 in compliance with SAE 
J2210. Other equipment may not recycle 
refrigerant to the required level of purity. A 
R134a Refrigerant Recovery Recycling
