To connect the electrical wiring on the
indoor unit
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ For instructions on how to connect the decoration panel
and the sensor kit, see the installation manual delivered
with the panel or the kit.
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
It is important to keep the power supply and the transmission wiring
separated from each other. In order to avoid any electrical
interference the distance between both wirings should ALWAYS be
at least 50 mm.
NOTICE
Be sure to keep the power line and transmission line apart
from each other. Transmission wiring and power supply
wiring may cross, but may NOT run parallel.

User interface cable
: Route the cable through the frame,
connect the cable to the terminal block, and fix the cable with a
cable tie.
3
Interconnection cable
(indoor↔outdoor): Route the cable
through the frame, connect the cable to the terminal block
(make sure the numbers match with the numbers on the
outdoor unit, and connect the earth wire), and fix the cable with
a cable tie.
4
Divide the small sealing (accessory) and wrap it around the
cables to prevent water from entering the unit. Seal all gaps to
prevent small animals from entering the system.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
5
Reattach the service cover.
NOTICE
When closing the service cover, make sure that the
tightening torque for screws is ≤1.5N•m.
▪ Following installation is for pair type or multi-system. For more
installation options, see the Installer reference guide of the indoor
unit.

Field settings
Make the following field settings so that they correspond with the
actual installation setup and with the needs of the user:
▪ Ceiling height
▪ Design decoration panel (if applicable)
▪ Air flow direction
▪ Air volume when thermostat control is OFF
▪ Time to clean air filter
Setting: Ceiling height
This setting must correspond with the actual distance to the floor,
capacity class and air flow directions.
▪ For 3-way and 4-way air flows (which require an optional blocking
pad kit), see the installation manual of the optional blocking pad
kit.
▪ For all-round air flow, use the table below.
