ADOPTION OF R32 REFRIGERANT
This air conditioner adopts the HFC refrigerant (R32) which does not destroy the ozone layer.
This outdoor unit is designed exclusively for use with R32 refrigerant. Be sure to use in combination with a R32
refrigerant indoor unit.
Regulation of harmonic current
<Single-phase Model>
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than
or equal to Ssc (*1) at the interface point between the user's supply and the public system. It is the
responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network
operator if necessary, that the equipment is connected only to a supply with a short-circuit power Ssc greater
than or equal to Ssc (*1).

This unit complies with EN 61000-3-11.
However, the impedance of the power supply system to be connected to the unit at the incoming power
point must be less than the Zmax given below.
In order to meet this condition, consult with the supply authority as required.
Zmax = 0.403 (Ω)
In addition, it is recommended that voltage drops occurring during the unit's operation in the area at the power
input shall be around 3.3% of the nominal power-supply voltage or less.
<Three-phase Model>
This equipment complies with IEC 61000-3-2 as professional equipment.
