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.
