(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 larger. (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.
