On this unit, it is required to set the addresses of the indoor units before starting air conditioning.
Set the addresses following the steps below.
CAUTION
• Be sure to complete the electric wiring before setting the addresses.
• If you turn on the outdoor unit before turning on the indoor units, the CODE No. [E19] is indicated on the
7 - segment display on the interface P.C. board of the outdoor unit until the indoor units are turned on. This is not
a malfunction.
• It may take up to ten minutes (normally about
fi
ve minutes) to address one refrigerant line automatically.
• Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)
• Running the unit is not required for address setting.
Before setting the address, set the DIP-SW on the header outdoor unit interface P.C. board.
1. Follow the steps below to open the electrical control box cover
(1). Loosen the screws on the left and right side of the electrical control box cover.
(2). Remove the screw A for MMY-SUG160,180, 200, 220 and 240.
(There is no screw A for MMY-SUG080, 100, 120 and 140.)
Screw A
(3). Hold the lower side of the electrical control box cover to draw it toward you while lifting it up, and remove the
electrical control box cover.
Regulation of harmonic currents
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)
Furthermore, when similar equipment or other equipment which may cause harmonic current emissions are to be
connected to the same interface point with this equipment, to reduce the risk of possible problems which may be
cause from addition of those harmonic current emissions, it is recommended to make sure that the short-circuit
power Ssc at the interface point is greater than the sum of the minimum Ssc required by all the equipment which
will be connected to the interface point.
