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.

MCY-MHP0406HT-E
MCY-MHP0506HT-E
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 = 0.39 (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.

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 five 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 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 cover of electrical control box, to avoid electric
shock.
Do not remove the cover of electrical control box.
