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.
