VTL-66
< PRECAUTION >[WITH 7 INCH DISPLAY]
PRECAUTIONS
Ventilate work area before resuming service if accidental system discharge occurs. Additional health
and safety information may be obtained from refrigerant and lubricant manufacturers.
 Never release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant each time an air conditioning system is discharged.
 Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
 Never store or heat refrigerant containers above 52°C (126°F).
 Never heat a refrigerant container with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
 Never intentionally drop, puncture, or incinerate refrigerant containers.
 Keep refrigerant away from open flames: poisonous gas is produced if refrigerant burns.
 Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-
cation.
 Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
Refrigerant ConnectionINFOID:0000000003894451
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
 Expansion valve to evaporator
 Refrigerant pressure sensor to liquid tank
O-RING AND REFRIGERANT CONNECTION
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Never confuse O-
rings since they are not interchangeable. Refrigerant may leak at the connection if a wrong O-ring is
installed.

WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.
 Store it in the same way at it is when mounted on the car when the compressor is removed. Failure
to do so causes lubricant to enter the low-pressure chamber.
 Use always a torque wrench and a back-up wrench when connecting tubes.
 Plug immediately all openings to prevent entry of dust and moisture after disconnecting tubes.
 Connect the pipes at the final stage of the operation when installing an air conditioner in the vehicle.
Never remove the seal caps of pipes and other components until just before required for connection.
 Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
 Remove thoroughly moisture from the refrigeration system before charging the refrigerant.
 Replace always used O-rings.
 Apply lubricant to circle of the O-rings shown in illustration when connecting tube. Be careful not to
apply lubricant to threaded portion.
 O-ring must be closely attached to the groove portion of tube.
 Be careful not to damage O-ring and tube when replacing the O-ring.
 Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.

PRECAUTIONS
 Perform leakage test and make sure that there is no leakage from connections after connecting line.
Disconnect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
Service EquipmentINFOID:0000000003894452
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation 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.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched
OFF after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following.
 Vacuum pumps usually have a manual isolator valve as part of the
pump. Close this valve to isolate the service hose from the pump.
 Use a hose equipped with a manual shut-off valve near the pump
end for pumps without an isolator. Close the valve to isolate the
hose from the pump.
 Disconnect the hose from the pump if the hose has an automatic
shut-off valve. As long as the hose is connected, the valve is open
and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
