• Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
• Be careful when connecting service equipment.
• Do not breathe refrigerant or vapor.
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. 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.
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

B
• Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
• Be careful when connecting service equipment.
• Do not breathe refrigerant or vapor.
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.
3. If the low-pressure does not reach more than 93.3
kPa (700 mmHg, 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 on page 21-
59).

2. Evacuate the system (see page 21-57).
3. Add the same amount of new refrigerant oil to the
system that was removed during recovery. Use
only DENSO ND-OIL 8 refrigerant oil.
4. Charge the system with the specified amount of
R-134a refrigerant. Do not overcharge the system;
the compressor will be damaged.
Select the appropriate units of measure for your
refrigerant charging station.
5. Check for refrigerant leaks (see page 21-59).
6. Check for system performance (see page 21-60).

• Compressed air mixed with R-134a forms a
combustible vapor.
• The vapor can burn or explode causing serious
injury.
• Never use compressed air to pressure test
R-134a service equipment or vehicle air
conditioning system.
• Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
• Be careful when connecting service equipment.
• Do not breathe refrigerant or vapor.
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.
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
1. 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.
2. Open high pressure valve to charge the system to
the specified capacity, then close the supply valve,
and disconnect the charging station fittings.
Select the appropriate units of measure for your
refrigerant charging station.
3. Check the system for leaks using a R-134a
refrigerant leak detector with an accuracy of 14 g
(0.5 oz) per year or better.
4. If you find leaks that require the system to be
opened (to repair or replace hoses, fittings, etc.),
recover the system.
5. After checking and repairing leaks, the system
must be evacuated.
