WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.
WARNING
▪ Do NOT use locally purchased electrical parts inside
the product.
▪ Do NOT branch the power supply for the drain pump,
etc. from the terminal block. This could result in
electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes
without thermal insulation as such pipes will be very hot.

components
NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.

7.2 To connect the electrical wiring to
the indoor unit
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.
NOTICE
▪ Keep the power line and transmission line apart from
each other. Transmission wiring and power supply
wiring may cross, but may NOT run parallel.
▪ In order to avoid any electrical interference, the
distance between both wirings should ALWAYS be at
least 50 mm.
Electrical work should be carried out in accordance with the
installation manual and the national electrical wiring rules or code of
practice.
