Running-in operation
Whenever moving parts have been replaced, it is
necessary to run-in both the compressor and the
magnetic clutch.
Compressor running-in
Reassembled compressors must be run-in after
the leak test (see next page).
1. Check that the compressor contains the
specified amount of oil.
2. Interconnect the suction fitting and the dis-
charge fitting with the flexible hose.
3. Connect the two connector ports using a
flexible hose
4. Run the compressor at 500r/min for 30 min-
utes to 60 minutes. This operation may be
performed by an electric motor or the engine
of an automobile.
5. Replace the oil.
6. Repeat the leak test.
Magnetic clutch running-in
1. Install the clutch on the compressor.
2. Install the compressor on the test bench,
and operate the compressor by running the
system.
3. Maintain the compressor speed at 500 rpm.
Operate the A/C switch through the ON/OFF
cycle at least 50 times (“ON” for 10 seconds
and “OFF”for 10 seconds).
CAUTION!
While the compressor is being run-in in step
3 above, check the outside temperature of
the front head. If the temperature exceeds
80°C (176°F), stop the running-in operation.
Resume the operation when the head has
cooled.
