 Use the field supplied RC wiring with at least 1 mm in thickness of insulation part including the sheath.
Wiring Regulations may differ depending on location. For field wiring rules, please refer to your
LOCAL ELECTRICAL CODES.
You must ensure that installation complies with relevant rules and regulations.
 Be careful not to connect cables to other terminals of indoor units (e.g. power source wiring terminal).
Malfunction may occur.
 Do not bundle together with the power source wiring or store in the same metal tube. Operation error
may occur.
 If noise is induced to the unit power supply, attach a noise filter.

2Mount to the wall.
There are 2 types of wall-mounting methods: Exposed type and Embedded type.
Mounting the bottom case
Tighten the screws securely until the screw heads touch the bottom
case.
(Otherwise, loose screw heads may hit the PCB and cause
malfunction when mounting the top case.)
Do not over-tighten the screws.
(The bottom case may be deformed, resulting in the unit becoming
detached from the surface it is fixed to.)
Connection to the remote controller terminal board
Depress the push button using a round bar or finger, insert the
remote control wiring securely from the wiring insertion slot and
release the push button.
Pull the remote control wiring lightly, and confirm it is secured.
There is the danger of shorting if copper wire is exposed. Make sure
the wire is properly inserted.
