WARNING:
- Check to ensure that the accessories are packed with
the indoor unit.
- 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. It
is recommended that the indoor units be installed 2.3 to
3 meters from the floor level. If the unit is installed
higher than 3 meters, it is also recommended that a fan
be utilised to obtain uniform air temperature in the room.
- 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.
- This unit is exclusive non electrical heater type indoor
unit. It is prohibited to install a electrical heater in the
field.
- Mount suspension bolts using M10 (W3/8) as size, as
shown below:

CAUTION:
- Do not install the indoor units in a flammable
environment to avoid a fire or an explosion.
- Check to ensure that the ceiling slab is strong enough.
If not strong enough, the indoor unit may fall down on
you.
- Do not install the indoor units, outdoor unit, remote
control switch and cable within approximately 3 meters
of strong electromagnetic wave radiators such as
medical equipment.
- Do not install the indoor units in a machinery shop or
kitchen where vapor from oil or mist flows to the indoor
units. The oil will deposit on the heat exchanger,
thereby reducing the indoor unit performance, and may
deform. In the worst case, the oil damages the plastic
parts of the indoor unit.
- To avoid any corrosive action to the heat exchangers,
do not install the indoor units in an acid or alkaline
environment.
