Space requirements

1. Since refrigerant noise can be generated during the MCU operation, do not install the unit on the ceiling of the places

that requires silence such as bedrooms, libraries, hospitals and offices etc.

2. Do not install the MCU in the ceiling of the living area. Otherwise, noise generated from the MCU may disturb people in

that area and cause inconvenience.

<Spaces with developed ceiling>

<Ceiling of the office>
