• Do not install the indoor units outdoors. If installed outdoors, an
electric hazard or electric leakage will occur.
• Consider the air distribution from each indoor unit to the space
of the room, and select a suitable location so that uniform air
temperature in the room can be obtained.
• Avoid obstacles which may hamper the air intake or the air
discharge flow.
• Pay attention to the following points when the indoor units are
installed in a hospital or other places where there are electronic
waves from medical equipment, etc.
- Do not install the indoor units where electromagnetic wave is
directly radiated to the electrical box, remote control cable
or remote control switch.
- Install the indoor units and components as far as practical or
at least 3 meters from the electromagnetic wave radiator.
- Prepare a steel box and install the remote control switch in
it. Prepare a steel conduit tube and wire the remote control
cable in it. Then connect the ground wire with the box and
tube.
- Install a noise filter when the power supply emits harmful
noises.
