Items Notes Countermeasures
Noise of the outdoor unit Note that the noise level specified on the
specification sheet is measured an
anechoic room. The noise level varies
much depending on the installation condi-
tion (e.g. echo condition) on site. ΠDo not install in a place such as resi-
dential area where silence is required.
ΠConsult the dealer when the noise is a
concern at the installation site.
Influence of noise Low noise is generated from the power
supply, the transmission line, or the unit
body as a microcomputer is used in the air-
conditioner. Equipment, such as wireless
microphones or medical equipment, that
amplifies a minute electric signal may mal-
function due to noise if the unit is installed
adjacent to such equipment.
If the unit is installed adjacent to equip-
ment, such as electric discharge machine,
that generates high noise, the unit may
malfunction due to noise generated from
such equipment. To avoid this, take coun-
termeasures described on the right. ΠInstall the equipment, such as receiv-
ers or antennas of wireless micro-
phones, that may malfunction due to
noise as far as possible away from the
transmission line, the power supply of
the unit, or the unit body.
ΠKeep the power supply line of the
equipment that emits high noise away
from the power source of the air-condi-
tioner, and install the transmission line,
the power supply line, and the unit
body as far as possible away from
such equipment.
