PRECAUTIONS
Precaution for Service of Compressor
INFOID:0000000005930830
• Plug all openings to prevent moisture and foreign matter from entering.
• When the compressor is removed, store it in th e same position as it is when mounted on the car.
• When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor”
exactly. Refer to MTC-17, "
Maintenance of Oil Quantity in Compressor".
• Keep friction surfaces between clut ch and pulley clean. If the surface is contaminated, with oil, wipe
it off by using a clean waste cloth moistened with thinner.
• After compressor service operation, turn the compresso r shaft by hand more than five turns in both
directions. This will equally distribute oil inside the compressor. After the compressor is installed,
let the engine idle and operate the compressor for one hour.
• After replacing the compressor magnet clutch, ap ply voltage to the new one and check for usual
operation.
Precaution for Service EquipmentINFOID:0000000005930831
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.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer’s instruct ions for tester operation and tester maintenance.
VACUUM PUMP
The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure. So the vac-
uum pump oil may migrate out of the pump into the service hose.
This is possible when the pump is switched off after evacuation (vac-
uuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
• Usually vacuum pumps have a manual isolator valve as part of the pump. Close this valve to isolat e the service hose from the pump.
• For pumps without an isolator, use a hose equipped with a manual shut-off valve near the pump end. Close the valve to isolate the
hose from the pump.
• If the hose has an automatic shut -off valve, disconnect the hose
from the pump. 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 a no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2 ″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified oils.
