Preparation of indoor unit
Mounting of connecting wires
① Remove the lid.
② Remove the terminal cover.
③ Remove the wiring clamp.
④ Connect the connecting wire securely to the terminal block.
1) Connect the connection wire securely to the terminal block. If
the wire is not affixed completely, contact will be poor, and it is
dangerous as the terminal block may heat up and catch fire.
2) Take care not to confuse the terminal numbers for indoor and
outdoor connections.
⑤ Fix the connecting wire by wiring clamp.
⑥ Attach the terminal cover.
⑦ Attach the lid.
Installing the support of piping
Piping is possible in the rear, left, left rear,

Use cables for interconnection wiring to avoid loosening of the
wires. CENELEC code for cables Required field cables.
