3. Refrigerant Recovery Proce-
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 recycle the gas.
• When recycling the discharged refrigerant,
keep service cans on hand. Because the recov-
ery 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-26, PROCEDURE, Compressor Oil.>

of manifold gauge set are fully closed.
4) Install the low/high pressure hoses to the service
ports on the low/high pressure sides of the vehicle
respectively.
5) Connect the center hose to the refrigerant recov-
ery system.
6) Follow the operation manual to activate the re-
frigerant recovery system.
