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.
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.

Do not put any foreign material into the indoor unit
-
and check to ensure that none exist in the indoor unit
before the installation and test running. Otherwise a
fire or failure, etc., may occur.

-
harmful noises..
This unit is exclusive non electrical heater type indoor
-
unit. It is prohibited to install a electrical heater in the
field.
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.
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.
