3. Install the receiver/dryer in the reverse order of removal, and note these items:

Replace the O-rings with new ones, and apply a thin coat of refrigerant oil
(SP-10) before installing them. Be sure to use the correct O-rings for
HFC-134a (R-134a) to avoid leakage.

Install the cap to the specified torque. It is made of resin a can be easily
stripped.

REFRIGERANT RECOVERY

CAUTION:

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.

NOTE:

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 an 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.

High-Pressure And Low-Pressure Service Port

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

CAUTION:

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.

1. When an A/C System has been opened to the atmosphere, such as during

installation or repair, it must be evacuated using an 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 an 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
