Connection Conditions›
The following restrictions must be observed in order to maintain the indoor units’ connection to the same
system.
The total connected capacity of the standard indoor units and fresh air treatment units must be between›
50% and 100% of the capacity of the air conditioning outdoor units. The connected capacity of the fresh air
treatment units must not exceed 30% of the capacity of the air conditioning outdoor units.
A fresh air treatment unit can also be used exclusively. The connected capacity of the fresh air treatment unit›
must be between 50% and 100% of the capacity of the air conditioning outdoor unit.

Total connected capacity of standard indoor units and fresh air›
treatment unit does not exceed 100%.
System capacity of 20 HP = indoor unit capacity of 20 HP.›
Connected capacity of fresh air treatment unit does not exceed›
30% of this.
Since system capacity of 20 HP x 0.3 = 6 HP > fresh air›
treatment unit capacity = 5 HP.
2. 100% FRESH AIR INTAKE POSSIBLE
By introducing outdoor air into the room and adjusting the outdoor air temperature via fixed discharge temperature
control, the system reduces the load on the air conditioner.
System Example›
Check that system connected capacity is within the appropriate range.
