7) Note the low-pressure gauge reading.
8) Leave it at least 5 minutes, and then check the
low-pressure gauge reading for any changes.
If the gauge indicator shows near zero point, it is a
sign of leakage. Check pipe connector points, re-
pair them, and make sure there is no leakage.
9) Follow the can tap operation manual, install to
the refrigerant can.

10) Disconnect the center manifold hose from the
vacuum pump, and connect the hose to the tap
valve.
11) When a 13.6 kg (30 lb) refrigerant container is
used, measure the weight of the refrigerant amount
to use using a scale.

12) Confirm that all the 3 hoses are connected se-
curely to the manifold gauge set.
AC-00027
13) Open the valve on the HFC-134a source.
14) Loosen the center hose connection on the
manifold gauge set (if applicable, press a purge
valve on the manifold gauge set) for a few seconds
to discharge the air in the center hose by the refrig-
erant pressure.
15) Stop the engine and carefully open the high-
pressure valve.
CAUTION:
Do not open the low-pressure valve.

CAUTION:
Never run the engine while charging from the

high-pressure side.
16) Close the high-pressure valve when the low-
pressure gauge reaches 98 kPa (1 kg/cm
Using a leak tester, check the system for leaks.
If any leakage is found after the refrigerant recov-
ery is completed, repair the applicable area.
