5. Indoor Unit and Outside Unit Capacity Index
5.1 Outside Unit Selection
See the indoor unit capacity tables for given Indoor and outside(outdoor) temperature. Select the unit whose
capacity is the nearest to or greater than given load.
Note
Individual Indoor Unit capacity is subject to change by combination. Actual capacity has to be calculated according
to the combination by using outside unit capacity table.
5.2 Outside Unit Selection
Allowable combinations are indicated below. In general, outside unit can be selected depending on the location of
the unit, zoning and usage of the rooms.
The indoor and outside unit combination is determined by comparing the sum of indoor unit capacity index with
each Outside Unit. It is recommended to be the nearest to 100% combination ratio or to be smaller than that. Refer
the table below. To manage cooling/heating load properly, it's better to be selected the bigger capacity outside unit
rather than the nearest, if the installation space is large enough.
Allowable Total Capacity Index Table of Combined Indoor Units
* Capacity Index is same as the capacity(kW).

CAUTION
•Ratio of the running Indoor Units to the Outside: Within 10 ~ 100%
•A combination operation over 100% cause to reduce each indoor unit capacity.
Combination ratio (50~200%)
Notes :
1. We can guarantee the operation only within 130% Combination Ratio.
If you want to connect more than 130% combination Ratio, please contact us and discuss the
requirement.
2. In case that operating indoor units ratio to rated capacity of Outside unit is more than 130%, the airflow
should be operated as low step in the all indoor units.

3. Power factor could vary less than ±1% according to the operating conditions.
4. Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
Sound power level is measured on the rated condition in the reverberation rooms by ISO 3741 standard.
Therefore, these values can be increased owing to ambient conditions during operation.
5. Sound values of combination model are calculated values based on sound results of independent models.
Sound values can be increased owing to ambient or installation conditions during operation.
Sound values of system [dB(A)] = 10*log [10^(A1/10)+ ... +10^(An/10)] , A1~An means sound values of independent models.
6. Performances are based on the following conditions :
• Cooling : Indoor Ambient Temp. 27°CDB / 19°CWB, Water inlet temp. 30°C
• Heating : Indoor Ambient Temp. 20°CDB / 15°CWB, Water Inlet temp. 20°C
• Interconnected Pipe Length is 7.5m and difference of Elevation (Outdoor ~ Indoor Unit) is 0m.
7. *** : The number in parentheses means maximum connectable indoor units in accordance with outdoor units combination (160~200%).
The recommended ratio is 130%.

1. Due to our policy of innovation some specifications may be changed without notification.
2. Wiring cable size must comply with the applicable local and national codes. And “Electric characteristics” chapter should be considered for electrical
work and design. Especially the power cable and circuit breaker should be selected in accordance with that.
3. Power factor could vary less than ±1% according to the operating conditions.
4. Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
Sound power level is measured on the rated condition in the reverberation rooms by ISO 3741 standard.
Therefore, these values can be increased owing to ambient conditions during operation.
5. Sound values of combination model are calculated values based on sound results of independent models.
Sound values can be increased owing to ambient or installation conditions during operation.
Sound values of system [dB(A)] = 10*log [10^(A1/10)+ ... +10^(An/10)] , A1~An means sound values of independent models.
6. Performances are based on the following conditions :
• Cooling : Indoor Ambient Temp. 27°CDB / 19°CWB, Water inlet temp. 30°C
• Heating : Indoor Ambient Temp. 20°CDB / 15°CWB, Water Inlet temp. 20°C
• Interconnected Pipe Length is 7.5m and difference of Elevation (Outdoor ~ Indoor Unit) is 0m.

Note
1. Due to our policy of innovation some specifications may be changed without notification.
2. Wiring cable size must comply with the applicable local and national codes. And “Electric characteristics” chapter should be considered for electrical
work and design. Especially the power cable and circuit breaker should be selected in accordance with that.
3. Power factor could vary less than ±1% according to the operating conditions.
4. Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
Sound power level is measured on the rated condition in the reverberation rooms by ISO 3741 standard.
Therefore, these values can be increased owing to ambient conditions during operation.
5. Sound values of combination model are calculated values based on sound results of independent models.
Sound values can be increased owing to ambient or installation conditions during operation.
Sound values of system [dB(A)] = 10*log [10^(A1/10)+ ... +10^(An/10)] , A1~An means sound values of independent models.
6. Performances are based on the following conditions :
• Cooling : Indoor Ambient Temp. 27°CDB / 19°CWB, Water inlet temp. 30°C
• Heating : Indoor Ambient Temp. 20°CDB / 15°CWB, Water Inlet temp. 20°C
• Interconnected Pipe Length is 7.5m and difference of Elevation (Outdoor ~ Indoor Unit) is 0m.
7. *** : The number in parentheses means maximum connectable indoor units in accordance with outdoor units combination (160~200%).
The recommended ratio is 130%.
8. This product contains Fluorinated greenhouse gases.(R410A, GWP(Global warming potential) = 2,087.5)
