Recovery
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system
CAUTION: Exposure to air conditioner relrigerant and
lubricant vapor or mist can illitate eyes, noss and
throat. Avoid breathing the ail conditioner refrigerant
and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
compressed air.
!@@ some mixtures ot air and R'13'[a havo been
strown to be combustiblg at elevated pressures and Gan
resuh in fire or explosion causing iniury or property dam-
age, Never use compressed air to pressure test R-134a
service equipment or vehicle air conditioner systems.
Additional health and safetv information may be obtained
from the refrigerant and lubricant manufacturers.
1, Connect a R-'134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown. tollowing
the equipment manufacturer's instluctions.
2. Measure the amount of refrigerant oil removed from
the A/C svstem after the recovery process is com-
pleted.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the Iy'C system before charg-
tno.

Remove the self-tapping screws and clamps from
the housings.
Carefully separate the housings, then remove the
evaporator.
lf necessary, remove the expansion valve.
NOTE: When loosening the expansion valve nuts, use
a second wrench to hold the expansion valve or the
evaporator pipe. Otherwise, they can be damaged
5. Assemble in the reverse order of disassembly Make
note of following items.
. Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage.
. Install the expansion valve capillary tube so that
it is in direct contact with the suction line. Then
wrap wath taPe.
. Reinstall the Ay'C thermostat sensor to its original
location.

from the refrigerant and lubricant manuJacturers'
When an A,/C System has been opened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a R-134a refrigerant recovery/
recycling/charging station. (lf the system has been
open for several days, the receiver/dryer should be
replaced, and the system should be evacuated for
several hours.)
Connect a R-134a refrigerant recovery/
recycling/charging station to the vehicle, as shown'
following the equipment manufacturer's instruc-
trons.
NOTE: lf low pressure does not reach more than 93 3
kPa (7OO mmHg,27.6 in.Hgl in 15 minutes, there is
probably a leak in the system Partially charge the
system, and check for leaks (see Leak Test)

Open the high-pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.

Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 9 10.5 ozlper yea. or better.
lf you find leaks that require the system to be opened(to repair or replace hoses. fittings. etc.), recover the
system according to the Recovery Procedure on page
22-27.
After checking and repairing leaks. the system must
be evacuated (see System Evacuation on page 22-451.
