2. Measure the amount of refrigerant oil removed from the A/C system after the recovery process is 

completed. Be sure to put the same amount of new refrigerant oil back into the A/C system before 
charging.  

SYSTEM EVACUATION 

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove 
HFC-134a (R-134a) from the air conditioning system. 

If accidental system discharge occurs, ventilate work area before resuming service. 

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers. 

1. When an A/C System has been opened to the atmosphere, such as during installation or repair, it must be 

evacuated using a R-134a refrigerant recovery/recycling/charging station. (If the system has been open 
for several days, the receiver/dryer should be replaced, and the system should be evacuated for several 
hours.)  

2. Connect a R-134a refrigerant recovery/recycling/charging station (A) to the high-pressure service port (B) 

and the low-pressure service port (C), as shown, following the equipment manufacturer's instructions. 
Evacuate the system. 

CAUTION:

z

Air conditioning refrigerant or lubricant vapor can irritate your eyes, 
nose, or throat.  

z

Be careful when connecting service equipment.  

z

Do not breathe refrigerant or vapor.

3. If the low-pressure does not reach more than 93.3 kPa (700 mm Hg, 27.6 in. Hg) in 15 minutes, there is 

probably a leak in the system. Partially charge the system, and check for leaks (see step 3 of 
REFRIGERANT LEAK TEST ).
