1. Safety Instructions
• Read all Safety Instructions before using this device.
• This manual contains important safety information. Be sure to comply with all instructions.
• After installing the controller, provide this Installation Manual to the user.
Instruct users to store their room air conditioner Instruction Manual and Warranty in a safe location.
Warning
(Improper handling may have serious consequences, including injury or death.)
■ Users should not install the centralized controller themselves.
Improper installation may result in fire, electric shock, or damage/water leaks if the centralized controller falls. Consult the
retailer or specialty store where you purchased the unit for referral to an installer.
■ The centralized controller should be securely installed in accordance with the enclosed Installation Instructions.
Improper installation may result in fire, electric shock, or damage/water leaks if the centralized controller falls.
■ The unit should be mounted in a location that can support its weight.
If installed in an area that cannot support the unit, the centralized controller could fall and cause damage.
■ Securely attach the electrical component cover to the centralized controller.
If the electrical component cover of the centralized controller is not securely attached, dust or water penetration could occur,
resulting in a fire or electric shock.
■ Mitsubishi components or other designated components should be used for installation.
Improper installation may result in fire, electric shock, or damage/water leaks if the centralized controller falls.
■ When performing electrical work, adhere to the Technical Standards Regarding Electrical Equipment and the Interior Wiring Standards, follow the instructions provided in the Instruction Manual, and be sure to use a dedicated
circuit.
Inadequate circuit capacity or improper installation could result in a fire or electric shock.

■ Mounting Wall
This centralized controller can be mounted on a wall with a thickness of 6–30 mm.
Since the maximum wall thickness for the centralized controller’s mounting screw M4 × 30 8 is 17 mm, use screws of the
appropriate length for the wall thickness if the wall is between 17 mm and 30 mm thick.
(The best length for an M4 mounting screw is the wall thickness plus 13 mm.)

2-2. Selecting an Installation Site
• The centralized controller 1 is an exposed, wall-mounted model.
Install the unit in a dry location.
• For information on selecting a mounting wall, see the “Mounting Wall” in section 2.
■ Switch Box
The centralized controller power and connection wiring is generally direct wired.
The switch box 3 supplied (with switch box covers for 2 units) should therefore be used for installing the centralized controller.
2-3. Electrical Work
• Use 1.5 mm2 power supply wire (2-core + ground).
• For the connection wire C, use a control cable CVV (0.5 mm2 3-core) or equivalent product.
CVV is a control cable which is sheathed in polyvinyl chloride with polyvinyl insulated wires inside.
• Complete the power supply wire and connection wire work before mounting the centralized controller.
• The electrical work should be performed in accordance with the Technical Standards Regarding Electrical Equipment and the
Interior Wiring Standards.
2-4. Assigning Air Conditioner Device Numbers
• The numbers (1–8) displayed on the control panel of the centralized controller 1 correspond to the numbers of each connected
air conditioner (device number).
• Assign air conditioner device numbers that correspond to the numbers shown on the control panel based on the structure of the
building or the layout of the rooms in which the air conditioners are installed.
