• 

R32 is heavier than air—as well as other refrigerants—so tends to accumulate at the base (in the vicinity of the floor). If R32 accumulates around base, it may reach 

a flammable concentration in case room is small. To avoid ignition, maintaining a safe work environment is required by ensuring appropriate ventilation. If a refriger

-

ant leak is confirmed in a room or an area where there is insufficient ventilation, refrain from using of flames until the work environment can be improved by ensuring 

appropriate ventilation.

•   Refrigerant pipes connection shall be accessible for maintenance purposes.

•   Install outdoor units in a place where at least one of the four sides is open, and in a sufficiently large space without depressions. 

•  When installing the unit in an area that is enclosed with walls such as a 

verandah, be sure to have enough space as shown below. 

  In this case, the air conditioning capacity and power consumption might 

deteriorate.

•  When there is a lack of airflow or there is a possibility of becoming short 

cycle, install an outlet guide and make sure there is enough space behind 

of the unit.

•  When installing two or more units, do not install the units in front or behind 

each other.
