CAUTION

The appliance is designed to be a built-in
appliance. It shall not be accessible to the general
public. Adequate measures have to be taken to

Install the unit in a place strong enough to
support its weight.

Poor installation is hazardous. It also causes
vibrations and unusual operating noise.

Provide the service space and the inspection
holes.

(Be sure to provide the inspection holes to inspect the
air filters, the heat exchange elements and fans.)

Do not install the unit directly against a ceiling or
wall.

(If the unit is in contact with the ceiling or wall, it can
cause vibration.)

This is a class A product. In a domestic
environment this product may cause radio
interference in which case the user may be
required to take adequate measures.

CAUTIONS
on installing the ducts

The parts marked with (*) are effective in reducing
blowing noise.

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.

When selecting installation materials, consider the
required volume of air flow and noise level in that
particular installation.

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.

Access inside the unit is only allowed through the
service hole. Install grilles in case no ducts are
installed.

Unit sound pressure level is less than 70 dB(A).
