Attention
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 fall of the unit.)

Installation
example
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.
For the RC wiring of field supply, please use insulated wires with sheath.
The insulation thickness should be at least 1 mm.
Regulations on wire diameters differ from locality to locality. For field wiring
rules, please refer to your LOCAL ELECTRICAL CODES before beginning.
You must ensure that installation complies with all relevant rules and regulations.
