G
The naked part of the wire core should be 10 mm and fix it to the terminal tightly. Then try to pull the
individual wire to check if the contact is tight. Improper insertion may burn the terminal.
G
Be sure to use only power cables approved from the authorities in your country. For example in Germany:
Cable type: NYM 3x1.5mm

, (fuse = 20A time delay)
Please refer to the installation manual for wire connection to the terminals of the units. The cabling must
G
meet the standards of electrical installation.
G
There is a AC voltage of 240V between the L and N terminals. Therefore, before servicing, be sure to
remove the plug from the AC outlet or switch off the main switch.

Insulation And Maintenance Of Pipe Connection
G
The connected terminals should be completely sealed with
heat insulator and then tied up with rubber strap.
G
Please tie the pipe and power line together with vinyl tape as
shown in the figure showing the installation of Indoor and
Outdoor units. Then fix their position with holders.
G
To enchance the heat insulation and to prevent water
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
G
Completely seal any gap with putty.

CAUTION
!
G
Please use a new socket. Accident may occur due to the use of old
socket because of poor contact.
G
Please plug in and then remove the plug for 2 – 3 times. This is to
ensure that the plug is completely plugged into the socket.
G
Keep additional length for the power cord and do not render the
plug under external force as this may cause poor contact.
G
Do not fix the power cord with U-shape nail.

Before installation, the power source must be checked and necessary
wiring work must be completed. To make the wiring capacity proper, use
the wire gauges list below for the lead-in from a pole transformer and for
the wiring from a switch board of fuse box to the main switch and outdoor
unit in consideration of the locked rotor current.

fixed on wall or beam.
To operate the remote controller at its holder, please ensure
G
that the unit can receive signal transmitted from the controller
at the place where the holder is to be fixed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the fluorescent light. Therefore,
during the installation of the remote control holder, please
switch on the light, even during day time, to determine the
mounting location of the holder.
The controller must
