*2) As an outdoor unit is located in a lower position than indoor unit, level difference is 40m. If outdoor unit is located in a higher position than indoor
unit, level difference is 110m or under. (If the level difference is higher than 50m, make a decision simulating by PDM kit installation Guide software
whether the PDM kit should be installed or not.) *PDM kit: Pressure Drop Modulation kit
The refrigerant amount of the system must be less than 100kg.
