Precautions for Service Equipment
RECOVERY/RECYCLING/RECHARGING EQUIPMENT
Be certain to follow the manufacturers instructions for machine
operation and machine maintenance. Never introduce any refriger-
ant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufactures instructions for tester opera-
tion and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
Since the vent side of the vacuum pump is exposed to atmospheric
pressure, it is possible for the vacuum pump lubricant to migrate
out of the pump into the service hose if the pump is switched off
after evacuation (vacuuming) and the service hose is not isolated
from the vacuum pump.
To prevent the migration of vacuum pump lubricant into service
hoses, it is necessary to use a valve (which can be manually
opened or closed) near the connection of the service hose to the
pump.
IOn a vacuum pump which is equipped with an isolator valve
(usually part of the vacuum pump), closing this valve will iso-
late the service hose from the pump.
IFor pumps without an isolator valve, be certain that the service
hose is equipped with a manual shut off valve near the pump
end of the hose.
IHoses which contain an automatic shut off valve at the end of
the service hose must be disconnected from the vacuum pump
to prevent the migration of lubricant: as long as the hose is
connected, the valve is open and lubricant may migrate.
One-way valves which open when vacuum is applied and close
under a no vacuum condition are not recommended, because this
valve may restrict the pump's ability to pull a deep vacuum.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Be cer-
tain that the manifold gauge set has the 1/2²-16 ACME threaded
connections for service hoses, and that no refrigerants other than
HFC-134a (R-134a) (along with only specified lubricants) have
been used with the manifold gauge set.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). Be certain that all hoses include
positive shut off devices (either manual or automatic) near the end
of the hoses opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to
an CFC-12 (R-12) A/C system. Although the HFC-134a (R-134a)
couplers will not secure on to the CFC-12 (R-12) system, CFC-12
(R-12) refrigerant and lubricant will be discharged into the HFC-
134a (R-134a) coupler, causing contamination.

REFRIGERANT WEIGHT SCALE
If the scale allows electronic control of the flow of refrigerant
through the scale, be certain that the hose fitting size is 1/2²-16
ACME, and that no refrigerant other than HFC-134a (R-134a)
(along with only specified lubricant) has been used with the scale.
CHARGING CYLINDER
The charging cylinder is not recommended because refrigerant
may be vented into the air from the top valve of the cylinder when
filling the cylinder with refrigerant. Additionally, the accuracy of the
cylinder is generally less than that of an electronic scale or of qual-
ity recycle/recharge equipment.

HFC-134a (R-134a) Service Procedure
DISCHARGING REFRIGERANT
WARNING:
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. To remove R-134a from the A/C system, use service equipment certified to meet the require-
ments of R-134a recycling equipment or R-134a recovery equipment. If accidental system discharge
occurs, ventilate work area before resuming service. Additional health and safety information may be
obtained from refrigerant and lubricant manufacturers.

qA
1. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure oil discharged into the recovery/recycling
equipment.
2. Drain the oil from the ªoldº (removed) compressor into a graduated container, and record the amount of oil drained.
3. Drain the oil from the ªnewº compressor into a separate, clean container.
4. Measure an amount of the new oil equivalent to that drained from the ªoldº compressor, and add this oil to the ªnewº com-
pressor through the drain plug or suction port opening.
5. Measure an amount of the ªnewº oil equivalent to that recovered during discharging, and add this oil to the ªnewº compressor
through the drain plug or suction port opening.
6. If the liquid tank also needs to be replaced, add an additional 5 m(0.2 Imp fl oz) of oil at this time.
Do not add this 5 m(0.2 Imp fl oz) of oil if only replacing the compressor.
