• Because your air conditioner contains R-32
refrigerant, make sure that it is installed, operated,
and stored it in a room whose floor area is larger
than the minimum required floor area specified in
the following table:

– A : Minimum required floor area
• IMPORTANT: it's mandatory to consider either the
table above or taking into consideration the local
law regarding the minimum living space of the
premises.
• Minimum installation height of indoor unit is 0.6 m
for floor mounted, 1.8 m for wall, 2.2 m for ceiling.
Installation of the outdoor unit
• While in installation or relocation of the product, do
not mix the refrigerant with other gases including
air or unspecified refrigerant. Failure to do so may
cause pressure increase to result in rupture or
injury.
• Do not cut or burn the refrigerant container or
pipings.
• Use clean parts such as manifold gauge, vacuum
pump, and charging hose for the refrigerant.
• Installation must be carried out by qualified
personnel for handling the refrigerant. Additionally,
reference the regulations and laws.
• Be careful not to let foreign substances (lubricating
oil, refrigerant, water, etc.) enter the pipings. The
application of oil or refrigerant deteriorates the
pipings to result in drain leakage. For storage,
securely seal their openings.
• When mechanical ventilation is required, ventilation
openings shall be kept clear of obstruction.
• For disposal of the product, follow the local laws
and regulations.
• Do not work in a confined place.
• The work area shall be blocked.
