34065 Oil injectOr fOr Servicing r-134a a/c SyStemS

WARNING

Unplug the unit before beginning service
work. Incorrect use or connections can
cause electrical shock.

Wear eye protection when working with
refrigerants. Contact with refrigerant can
cause eye injury.

Use extreme caution when disconnecting
hoses. Pressurized refrigerant may be
present in hoses. Point hoses away from
you and anyone nearby.

Use only PAG oil in the oil injector, and
then only to service vehicles with R-134a
A/C systems. Use of other oils, or use
with other types of A/C systems, will
result in system failure.

Use only with refrigerant type R-134a.
Cross-contamination with other
refrigerant types will cause severe
damage to the A/C system, and to
service tools and equipment. Do not mix
refrigerant types through a system or in
the same container.

The oil injector is designed for use with a manifold
gauge set. Oil is charged into the system through the
blue low-side hose while the system is in a vacuum.

Note: It is important to keep the oil level above the
end of the dip tube in the bottle (at a minimum of one
ounce) to prevent air from entering the system.

HOOK-UP AND OPERATION

1. Recover used refrigerant from the system

following the manufacturer’s specications.

2. Open both manifold gauge valves, and verify
there is no pressure present on both gauges.

3.

While the system is in a vacuum, close the
manifold’s red high-side and blue low-side valves.

For Manifold: Attach the oil injector to the refrigerant
port of the manifold using a charging hose.

For Charging Stations: The oil injector should
already be installed onto the manifold. See
“Installation Instructions” on the next page.

4. Verify there is sufcient oil in the bottle. If not,

unthread the bottle from the cap, add oil to the
bottle, and thread the bottle tightly onto the cap.

5. Open the manifold’s blue low-side valve.

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 certied to meet the
requirements of SAE J2210 (R-134a recycling
equipment). If accidental system discharge occurs,
ventilate the work area before resuming service.
Additional health and safety information may
be obtained from refrigerant and lubricant
manufacturers.

Do not pressure test or leak test HFC-134a
service equipment or vehicle A/C systems using
compressed air. Some mixtures of air/HFC-134a
have been shown to be combustible at elevated
pressures. These mixtures are potentially

dangerous and may result in re or explosion

causing injury or property damage. Additional
health and safety information may be obtained from
refrigerant and lubricant manufacturers.

Do not open valve to pressurized system. The
No. 34065 Oil Injector is not designed for use with
high pressure.

6. Note the oil level in the injector bottle; then open
the oil injector valve. Watch the calibrations on
the bottle, allowing the correct amount of oil to
be charged into the system. Close the oil injector
valve to stop the oil charge (but do not go below
one ounce).

For Manifold: Close the low-side manifold valve,
and verify all valves are closed. Disconnect the oil
injector from the manifold, and continue recharging
or proceed with the next service operation.

For Charging Station: Close the oil injector valve;
then continue recharging as needed, or proceed with
the next service operation.

INSTALLATION INSTRUCTIONS

Follow these steps to install No. 34065 Oil Injector
on the 34100 Smart Cart or 34050 Manual Charging
Station:

1. Turn off the MAIN POWER switch, and unplug
the station from the power source. The station
must be disconnected from the vehicle.

2. Remove the 1/8" hex pipe from the left end of

the manifold, and install the tting adapter

included with the oil injector.

3. Attach No. 34065 to the adapter. The station is
ready for use.
