Warning:
Be sure to use speci fi ed wires for connections and ensure no external force is imparted to terminal connections. If connections are not fi xed fi rmly,
heating or fi re may result.
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
Some installation sites may require attachment of an earth leakage breaker for the inverter. If no earth leakage breaker is installed, there is a danger of
electric shock.
Do not use anything other than a breaker and fuse with the correct capacity. Using a fuse or wire of too large capacity may cause malfunction or
fi re.
Note:
This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the above table at the
interface point (power service box) of the user’s supply.
The user must ensure that this device is connected only to a power supply system which ful
fi ls the requirement above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
This equipment complies with IEC 61000-3-12 provided that the short-circuit power S
SC
is greater than or equal to S
SC
(*2) 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 S
SC
greater than or equal to S
SC
(*2).

12. Test run
12.1. The following phenomena do not represent faults.
Phenomenon Display of remote controller Cause
Indoor unit does not perform cooling
(heating) operation. “Cooling (heating)” fl ashes When another indoor unit is performing the heating (cooling) operation, the
cooling (heating) operation is not performed.
The auto vane rotates and begins to blow air
horizontally. Normal display If air has been blowing downward for 1 hour during cooling, the unit may
automatically change to horizontal blowing with the control operation of the
auto vane. During defrosting or immediately after heating start-up/shut-down,
the auto vane automatically rotates to blow air horizontally for a short period
of time.
Fan setting changes during heating. Normal display Ultra-low speed operation is commenced at thermostat OFF.
Light air automatically changes over to set value by time or piping temperature
at thermostat ON.
Fan stops during heating operation. Defrost display The fan is set to stop during defrosting.
Fan does not stop while operation has been
stopped. No lighting The fan is set to run for 1 minute after stopping to exhaust residual heat (only
in heating).
No setting of fan while start SW has been
turned on. Heat ready Ultra low-speed operation for 5 minutes after SW ON or until piping
temperature becomes 35°C, low speed operation for 2 minutes thereafter, and
then set notch is commenced (Hot adjust control).
Indoor unit remote controller shows “H0”
or “PLEASE WAIT” indicator for about
fi ve
minutes when turning ON universal power
supply.
“H0” or “PLEASE WAIT” fl ashes The system is being started up.
Operate remote controller again after “H0” or “PLEASE WAIT” disappears.
Drain pump does not stop when unit is
stopped. Light out After cooling operation stops, the unit continues to operate drain pump for
three minutes and then stops it.
Drain pump continues to operate while unit
has been stopped. Unit continues to operate drain pump if drainage is generated, even after the
unit has been stopped.
Indoor unit emits noise when switching from
heating to cooling and vice versa. Normal display This is a switching sound of the refrigerant circuit and does not imply a
problem.
Immediately after startup, the indoor unit
emits the sound of the refrigerant
fl ow.
Normal display Unstable fl ow of the refrigerant emits a sound. This is temporary and does not
imply a problem.
Warm air comes from an indoor unit that is
not performing a heating operation. Normal display The LEV is slightly open to prevent refrigerant, of the indoor unit that is not
performing the heating operation, from being lique
fi ed. This does not imply a
problem.

1. Use dedicated power supplies for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter.
Make sure the power-supply voltage does not drop more than 10%.
4. Speci fi c wiring requirements should adhere to the wiring regulations of the region.
5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed fl exible cord (design 245 IEC57).
6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air Conditioner installer.
