5.5 Preparing the installation of the
ducts
INFORMATION
▪ Flexible ducting with sound insulation is effective to
reduce blowing noises.
▪ When you select installation materials, consider the
required volume of air flow and the acceptable level of
noise for that particular installation.
▪ When the return air infiltrates into the ceiling and the
temperature and humidity in the ceiling become too
high, insulate the metal parts of the unit.
▪ ONLY use the service hole to access the inside of the
unit.
▪ The sound pressure level is less than 70 dBA.
CAUTION
▪ For safety reasons, the required minimum length of the
ducting is 1.5 m. If the ducting is shorter, or if no
ducting is installed, then you MUST install grilles in the
duct openings or the openings of the unit.
▪ Make sure no wind can blow in the ducting.
