4. Indoor Unit and Outdoor Unit Capacity Index
4.1 Selection procedure
■Outdoor units selection
In general, outdoor unit may be selected as follows, though the location of the unit, and usage of the room, etc.
should be considered.
The combination of indoor and outdoor unit was to be decided that the sum of indoor unit capacity index should
be smaller than the max. combination capacity of outdoor unit. Up to Max.9 indoor units can be connected to one
outdoor unit. It is recommended to choose a large capacity outdoor unit if the installation space is large enough.
MULTI Inverter (1 phase)
■Indoor units selection
Look up the table on combination of indoor and outdoor unit, and determine the appropriate indoor unit capacity
which satisfies the given thermal load.
For proper system operation, refer to the following:
1. At least 2 indoor units should be connected to outdoor unit.
2. Total capacity of indoor units connected should be minimum 40% of outdoor unit rated capacity.
3. Calculation method for the connectable total capacity of indoor unit sum up the capacity of indoor unit, but high
static duct type indoor unit capacity weights 1.3 times.

2. Specifications
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. Performances are based on the following conditions :
• *Cooling : Indoor Ambient Temp. 27°CDB / 19°CWB, Outdoor Ambient Temp. 35°CDB / 24°CWB
• *Heating : Indoor Ambient Temp. 20°CDB / 15°CWB, Outdoor Ambient Temp. 7°CDB / 6°CWB
• Interconnected Pipe is standard length and difference of Elevation (Outdoor ~ Indoor Unit) is 0m.

Multiple piping type
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. Performances are based on the following conditions :
• *Cooling : Indoor Ambient Temp. 27°CDB / 19°CWB, Outdoor Ambient Temp. 35°CDB / 24°CWB
• *Heating : Indoor Ambient Temp. 20°CDB / 15°CWB, Outdoor Ambient Temp. 7°CDB / 6°CWB
• Interconnected Pipe is standard length and difference of Elevation (Outdoor ~ Indoor Unit) is 0m.
6. This product contains Fluorinated greenhouse gases.
