31 - AIR CONDITIONING
Refrigerant Recovering/Draining
WARNING
 Take extra care when servicing the A/C system under high pressure.
 Because there is refrigerant under high pressure in the A/C system, it must be serviced by professional
technician. Otherwise, a wrong service procedure may cause a serious danger or fatal injury.
 If A/C system is discharged unexpectedly, ventilate the work place before servicing. In a closed work
place, a large amount of refrigerant is discharged, which may cause oxygen reduction and result in
smothering, causing a serious or fatal injury.

ENVIRONMENTAL PROTECTION
 Never drain the refrigerant in A/C system into the atmosphere directly, and avoid environmental
contamination.
CAUTION
 It is necessary to recover refrigerant with R134a refrigerant special recycling machine.
 DO NOT work near the open flame.
 Always dispose of recovered refrigerant as specified.
 Never charge R-12 to the refrigerant system which is designed to use R134a. These refrigerants are
incompatible, which could damage the A/C system.
 DO NOT race engine when vacuum pump operates or vacuum exists in the A/C system. Failure to do so
may result in serious damage to the A/C compressor assembly.
1. Open the hood, and loosen the joint cover of A/C high/low pressure line.
2. Connect the refrigerant recycling machine to A/C high/low pressure line joint.
a. Connect the red connector to A/C high pressure line
joint (1).
b. Connect the blue connector to A/C low pressure line
joint (2).
3. Open the high pressure valve and low pressure valve of refrigerant recycling machine.
4. Choose the "recovering" item on machine and make it start to operate.
5. Check the low pressure value on pressure gauge to ensure that the recycling is completed, and then turn
the machine off.
6. Disconnect the connections between refrigerant recycling machine and A/C line joint.
7. Reinstall the cover onto the refrigerant line joint.
