Environment-Friendly Alternative Refrigerant R-410A; Nomenclature - LG B62AWYN9L6 Installation Manual

Environment-friendly alternative refrigerant R-410A

- The refrigerant R-410A has the property of
higher operating pressure in comparison with
R22.
Therefore, all materials have the characteris-
tics of higher resisting pressure than R22
ones and this characteristic should be also
considered during the installation.
R-410A is an azeotrope of R32 and R125
mixed at 50:50, so the ozone depletion
potential (ODP) of R-410A is 0. These days
the developed countries have approved it as
the environment-friendly refrigerant and
encouraged to use it widely to prevent envi-
ronment pollution.

! CAUTION
• The wall thickness of the pipe should
comply with the relevant local and na-
tional regulations for the designed pres-
sure 3.8MPa
• Since R-410A is a mixed refrigerant, the
required additional refrigerant must be
charged in its liquid state.
If the refrigerant is charged in its
gaseous state, its composition changes
and the system will not work properly.
• Do not place the refrigerant container
under the direct rays of the sun to pre-
vent it from exploding.
• For high-pressure refrigerant, any unap-
proved pipe must not be used.
• Do not heat pipes more than necessary
to prevent them from softening.
• Be careful not to install wrongly to mini-
mize economic loss because it is ex-
pensive in comparison with R22.
