children will not play with them. If children play with a plastic
bag which was not torn apart, they face the risk of suffocation.

Be sure to shut off the power source of the unit and all
the other unit to connected to the unit before wiring.

Doing so may cause an electric shock or a malfunction.

Use only an earth leakage breaker and fuse of the
specified capacity.

If no earth leakage breaker is installed, it may cause an
electric shock.
Using fuse and wire or copper wire with too large capacity
may cause a malfunction of unit or fire.

A power-supply line and a transmission line do not band
together, or are not contained in the same metal pipe.

Doing so may cause a malfunction of unit.

This appliance must be earthed.

Make sure to install a protective earth(PE) line. Do not
connect the protective earth line to gas or water pipes,
lightning conductors or telephone grounding lines. Improper
grounding may cause an electric shock.

Turn on the power supply for LM ADAPTER.

If being used together with system controller, perform the initialization settings.
The indoor units will be idle until the LM ADAPTER initialization has been completed (LED002 goes out).

* This requires approximately 5 to 10 minutes.(If being used together with system controller, it will be approximately
3 minutes after the completion of the initialization settings.)
If you connect the power to the LM ADAPTER before connecting the power supply to the indoor units, the LED002 might
stay lit.
If this case arises, reset the power supply to the LM ADAPTER.

Confirm that the LM ADAPTER’S maintenance LED (LED003, 004) are not lit.

* If the LM ADAPTER’S maintenance LED (LED003, 004) are lit, refer to the next chapter “6. Troubleshooting”.

(Note 1) Always refer to the previous chapter “4. System Settings” before changing the system configuration,
such as the M-NET address.
* After confirming the above details, always refer to the following section “ 5-4 Test Run ” and make confirmations

with trial operations.
(Note 2) Turn all of the switches in the service switch (SW2) [OFF] to confirm the ON/OFF status of the above maintenance

LED (LED002, LED003 and LED004).
