•
Check to ensure that the accessories are packed with the indoor unit.
•
Do not install the indoor units outdoors. If installed outdoors, an elec-
tric 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.
•
Avoid obstacles which may hamper the air intake or the air discharge
flow.
•
Pay attention to the following points when the indoor units are in-
stalled 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 con-
nect 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 prohib-
ited to install a electrical heater in the field.
•
Do not put any foreign material into the indoor unit and check to en-
sure that none exist in the indoor unit before the installation and test
running. Otherwise a fire or failure, etc., may occur.

•
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.
