CAUTION
• Ratio of the connectable Indoor Units to the Outdoor: Within 50
~ 130%
• Ratio of running Indoor Units to the Outdoor: Within 10 ~ 100%
• A combination operation over 100% cause to reduce each in-
door unit capacity.
!
CAUTION
• The wall thickness of the piping should comply with the relevant
local and national regulations for the designed pressure 3.8MPa
• Since R410A is a mixed refrigerant, the required additional re-
frigerant 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 prevent it from exploding.
• For high-pressure refrigerant, any unapproved pipe must not be
used.
• Do not heat pipes more than necessary to prevent them from
softening.
• Be careful not to install wrongly to minimize economic loss be-
cause it is expensive in comparison with R22.

BEFORE INSTALLATION
Environment-friendly Alternative Refrigerant
R410A
The refrigerant R410A has the property of higher operating pressure in
comparison with R22.
Therefore, all materials have the characteristics of higher resisting
pressure than R22 ones and this characteristic should be also consid-
ered during the installation.
R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone
depletion potential (ODP) of R410A is 0. These days the developed
countries have approved it as the environment-friendly refrigerant and
encouraged to use it widely to prevent environment pollution.
