• 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. The unit must
not be installed below 2.3 metres from the floor level, with a
recommended installation height between 2.3 and 3 metres 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.
• Install a noise filter when the power supply emits harmful noises.

• This unit is exclusive non electrical heater type indoor unit. It is

• 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 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.
