(3) Preparation of indoor unit
(a) Mounting of connecting wires
S SRK25, 35GZ-L1
(i) Remove lid
(ii) Remove cover, terminal block cover
(iii) Insert connecting wire to terminal block securely.
1 Insert connecting wire up to the terminal block securely. If
poor insertion of conductor may result in imperfect contact
between the conductor and the terminal causing heat genera-
tion which may result in fire hazard.
2 Be careful not to confuse terminal numbers of connecting
wire between indoor and outdoor unit.
3 Use wiring clamp for connection wiring to avoid loosening
of the wire.
(iv) Install cover, terminal block cover.
(v) Install lid.
S SRK502Z-L
(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.
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.
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.

Note (1) Connection wiring should not exceed 15 m. If this length is exceeded, communication
errors are likely to occur between the outdoor and indoor units, which could stop the air
conditioner.
(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
circumstance.)
