Address setting
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.
• The addresses can be set manually.
Automatic addressing:
setting addresses using SW15 on the interface P.C. board on the header outdoor unit
Manual addressing:
setting addresses on the wired remote controller.
* When setting an address manually, the wired remote controller must temporarily be paired with an
indoor unit one-to-one. (when the system is organized for group operation and no Remote controller)
REQUIREMENT
• High voltage parts exist in the electrical control box.
If you set addresses on an outdoor unit, operate the
unit through the access door shown on the illustration
on the right to avoid electric shock. Do not remove the
cover of electrical control box.
* After
fi
nishing operations, close the access door cover
and
fi
x it with the screw.

Regulation of high frequency wave
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
caused 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.
