dure
A: PROCEDURE
CAUTION:
• During operation, be sure to wear protective
goggles and protective gloves.
• Connect the refrigerant recovery system with
the manifold gauge set to discharge the refrig-
erant from the A/C system and reuse it.
• When reusing the discharged refrigerant,
keep service cans on hand. Because the dis-
charge rate with the recovery system is approx.
90%, service cans are necessary to charge the
refrigerant.
• Follow the detailed operation procedure de-
scribed in the operation manual attached to the
refrigerant recovery system.
1) Perform the compressor oil return operation.
<Ref. to AC-25, PROCEDURE, Compressor Oil.>
