R410A Temperature/Pressure Chart
Table 7
the ambient and liquid temperatures should match
values given in Table 6. Refrigerant must be added to
lower approach temperature and removed to increase
approach temperature. Loss of charge results in low
capacity and efficiency.
5. If the system is low on charge, R410A refrigerant
must be added. Be aware of the R410A refrigerant
cylinder. It will be light maroon colored. Refrigerant
should be added through the suction valve in the
liquid state.
Some R410A cylinders are equipped
with a dip tube which allows liquid to be drawn
from the bottom of the cylinder without turning
the cylinder upside-down. The cylinder will be
marked if it is equipped with a dip tube.
