(3) Preparation of indoor unit
(a) Mounting of connecting wires
S 32, 40 models
(i) Remove lid.
(ii) Remove cover, terminal block cover.
(iii) Connect the connection wire securely to the terminal block.
1
Affix 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 out-
door connections.
3
Affix the connection wire using the wiring clamp.
(iv) Attach the terminal back cover.
(v) Attach the lid.
S 50, 56 models
(i) Open the suction grille, then remove the lid.
(ii) Remove the wiring clamp.
(iii) Pass the connecting wire to terminal block from behind of indoor
unit.
(iv) Connect the connecting wire securely to the terminal block.

Take care not to confuse the terminal numbers for indoor and out-
door connections.
3
Affix the connection wire using the wiring clamp.
(v) Fix the connecting wire by wiring clamp.
(vi) Attach the lid.
(vii) Close the suction grille.
Use cables for interconnection wiring to avoid loosening of the wires.
CENELEC code for cables Required field cables.
H05 RNR3G1.5 (Example)
H Harmonized cable type
05 300/500 volts
R Natural-and/or synth, rubber wire insulation
N Polychloroprene rubber conductors insulation
R Stranded core
3or5 Number of conductors
G One conductor of the cable is the earth conductor
(yellow/green)
1.5 Section of copper wire (mm
(b) Protective taping (Protect the cable with tape at the section where the cable passes through the hole opened on the wall.)
(c) Forming of pipe (Holding down the pipe at the root, change the pipe direction, extend it and adjust according to the
