● Check to ensure that the ceiling is sufficiently
strong to sustain the Switch Box. If the ceiling is
weak, abnormal sound and vibration may occur.
● When the electronic expansion valve in the
Switch Box is activated, a change in the typical
refrigerant flow sounds may be heard or
perceived from the Switch Box. Take the
following action to minimize the sound.
(A) Install the Switch Box inside the ceiling. As for
the ceiling material, select a material like a
plasterboard at least 9mm (1 inch), which
minimizes operation sound.
(B) Do not install the Switch Box in a place near
bedrooms or hospital rooms.
● When the operation is changed to cooling/
heating mode, a change in the typical refrigerant
flow sounds may be heard or perceived from the
Switch Box .
Therefore, install the Switch Box in the ceiling of
the corridor so that the refrigerant flowing sound
may not be heard in the room.
● Do not install the Switch Box in a hot or humid
place, such as a kitchen, to prevent
condensation on the outer surface of the
Switch Box .
When installing the Switch Box in such
places, apply additional insulation.
● Pay attention to the following points when the
Switch Box is installed in a hospital or other
facility where there are electronic waves from
medical equipment.
(A) Do not install the Switch Box where the
electromagnetic wave is directly radiated to
the electrical box or communication cable.
(B) Install the Switch Box and components as far
as practicable or at least 3m (10 ft) from the
electromagnetic wave radiator.
(C) Install a noise filte when the power supply
emits harmful noises.
● Ensure the installation place is convenient
for the refrigerant piping or electrical wiring
connection.
● Do not drill, or drive screws into the cabinet.
Use only mounting points provided.
