2 UNITS INSTALLATION
D A N G E R
• Check to ensure that the accesso.ries are packed with
the indoor unit.
• Do not install the indoor units outdoors. If installed out-
doors, 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 utili-
sed 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 prac-
tical 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.

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.
•
