! CAUTION
• The above list indicates the order in which the individual work
operations are normally carried out but this order may be varied
where local conditions warrants such change.
• The thickness of the piping should comply with the relevant local
and national regulations for the designed pressure 3.8 MPa.
• Since R410A is a mixed refrigerant, the required additional refrig-
erant 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.)

Notes :
1) Rating capacity on heating of Multi V IV Pro is same to rating
capacity on cooling. Please, do refer heating capacity in the
performance table carefully when you design heating capac-
ity by outdoor ambient temperature. All model selection for
capacity is not responsibility of LG.
2) We can guarantee the operation only within 130% combina-
tion ratio. If you want to connect more than 130% combina-
tion ratio, please contact us and discuss the requirement.
3) In case that operating indoor units ratio to rated capacity of
outdoor unit is more than 130%, the airflow should be oper-
ated as low step in the all indoor units.
4) In case of Space Saving Model (ARUN***LLN4), we can rec-
ommend the operation within 120% combination ration for
two or more combination.
5) The numbers in parentheses means maximum connectable
indoor units in accordance with outdoor units combination.
