1.8 SELECTION CHART SELECTION CHART
Correct the cooling and heating capacity in accordance with the operating conditions. The net cooling and heating capacity can be
obtained in the following way.
Net capacity = Capacity shown in the capacity tables (1.8.1) × Correction factors shown in the table (1.8.2) (1.8.3) (1.8.4).
Caution: In case that the cooling operation during low outdoor air temperature below -5°C is expected, install the outdoor unit
where it is not influenced by natural wind. Otherwise protection control by low pressure will be activated much more
frequently and it will cause insufficient capacity or breakdown of the compressor in worst case.
