8) Leave it at least 5 minutes, and then check the
low-pressure gauge reading for any changes.
When a gauge indicator shows near to zero point,
this is a sign of leakage. Check pipe connector
points, repair them, make sure there is no leakage
by air bleeding.
9) Following the can tap operation manual
instructions, install it 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 refrigerant amount in use using
a weighting scale.
12) Confirm that all the 3 hoses are tightly con-
nected to the manifold gauge set.
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) only for a couple
of seconds to allow the air in the center hose to
escape by the refrigerant.

15) Carefully open the high-pressure valve with
the engine stopping.
CAUTION:
Do not open the low-pressure valve.
CAUTION:
Never run the engine during 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.
17) After confirming that there are no leaks with
the leak test, charge the required amount of refrig-
erant.
CAUTION:
Never run the engine during charging from the
high-pressure side.
18) Close the high-pressure valve when;
¼ the readings of low- and high-pressure gauges
become almost equal, after the charging speed is
reduced,
¼ the HFC-134a source becomes empty, or
¼ the system is filled with the gas.
