● m : Total refrigerant charge in the system
● 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.
● The refrigerant pipings shall be installed in the position where there are no substances that may result
in corrosion.
● The following checks shall be performed for installation:
- The charging amount depends on the room size.
- The ventilation devices and outlets are operating normally and are not obstructed.
- Markings and signs on the equipment shall be visible and legible.
● Upon leakage of the refrigerant, ventilate the room. When the leaked refrigerant is exposed to flame,
it may cause generation of toxic gases.
● Make sure that the work area is safe from flammable substances.
● To purge air in the refrigerant, be sure to use a vacuum pump.
● Note that the refrigerant has no odour.
● The units are not explosion proof so they must be installed with no risk of explosion.
● This product contains fluorinated gases that contribute to global greenhouse effect. Accordingly, do
not vent gases into the atmosphere.
● Because the working pressure for R-32 is 1.6 times higher than that for R-22, use exclusive pipings
and tools specified. In case of replacing an R-22 model with an R-32 model, be sure to replace the
conventional pipings and flare nuts with exclusive ones.
● The models that use the refrigerant R-32 have a different thread diameter for the charging port to
prevent charging failure. Therefore, check its diameter (1/2 inch) in advance.
● Servicing shall be performed as recommended by the manufacturer. In case other skilled persons
are joined for servicing, it shall be carried out under supervision of the person who is competent in
handling flammable refrigerants.
● For servicing the units containing flammable refrigerants, safety checks are required to minimise the
risk of ignition.
