• Consider the air distribution from the indoor unit to the space of the room, and select a suitable location so that
uniform air temperature distribution can be obtained in the room. lt is recommended that the indoor unit is
installed 2.5 to 3 meters from the floor level.
• Do not install flammable parts in the service space for the indoor unit.
• Avoid obstacles which may hamper the air intake or the air discharge flow.
• Do not install the indoor unit in a machinery shop or kitchen where oil vapor or its mist flows to the indoor unit.
The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance, and may deform and
in severe case, break the plastic parts of the indoor unit.
• Pay attention to the following points when the indoor unit is installed in a hospital or other facilities where there
are electromagnetic waves from medical equipment:
(A) Do not install the indoor unit where the electromagnetic wave is directly radiated to the electrical box,
remate control cable or remate control switch.
(B) lnstall the indoor unit and components at least 3 meters from the electromagnetic wave radiator.
(C) Prepare a steel case and install the remate control switch in it. Prepare a steel conduit tube and wire the
remate control cable in it. Then, connect the ground wire with the box and the tube.
(D) lnstall a noise filter when the power supply emits harmful noises.
• To avoid any corrosive action to the heat exchanger, do not install the indoor unit in an acid or alkaline
environment. lf the indoor unit has to be installed in such environments, use corrosion-proof type unit.
Ensure that the below calculated nu mber is within 0.3kg/m
