(5) Evacuation (repeat)
1) Close the valve of the refrigerant cylinder. Then
remove the charging hose (green) from the
refrigerant cylinder, and connect it to the
refrigerant recovery machine.
< NOTE >
Keep the high pressure valve and the low
pressure valve of the gauge manifold closed.
2) Using the procedure under “Evacuation”, evacuate
the system until the high pressure gauge indicates
30 inHg (100 kPa) or higher. (For 15 minutes or more.)
3) After evacuation is complete, close the high and
the low pressure valves of the gauge manifold.
CAUTION
Make sure to evacuate the system twice or
more using the repetitive vacuum method.
Evacuate the system an additional time on
rainy or humid days.
10.4 Refrigerant Charging Work
(1) Refrigerant charging
4) Remove the charging hose (green) from the
vacuum pump, and connect it to the refrigerant
cylinder (R-410A).
5) Loosen the nut on the gauge manifold side of the
charging hose (green). Open the valve of the
