• 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.
• 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.
• Mount suspension bolts using M10 (W3/8) as size, as shown below:

• 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.
• When lifting or moving the indoor unit, use appropriate slings to avoid
damage and be careful not to damage the insulation material on units
surface.
