holes.
(Be sure to provide the inspection holes to inspect the

CAUTIONS
on installing the ducts
I
The parts marked with (*) are effective in reducing
blowing noise.
I
When using the unit at a quiet place, use the optional
silencer box and flexible duct at the part of the air
discharge outlet on the indoor side "SA" (supply air to
room) of the unit, to counter the noise.
I
When selecting installation materials, consider the
required volume of air flow and noise level in that
particular installation.
I
When the outdoor air infiltrates into the ceiling and the
temperature and humidity in the ceiling become high,
insulate the metal portions of the unit.
I
Access inside the unit is only allowed through the
service hole. Install grilles in case no ducts are
installed.
I
Unit sound pressure level is less than 70 dB(A).
