11.1

Preparing the installation site

Do NOT install a heat reclaim ventilation unit or air suction/discharge
grille in the following places:
▪ Places, such as machinery plants and chemical plants, where
noxious gases or corrosive components of materials such as acid,
alkali, organic solvent and paint are present.
▪ Places, such as bathrooms, subject to moisture. Moisture can
cause electrical shock, electric leakage and other failures.
▪ Places subject to high temperature or direct flames.
▪ Places subject to much soot. Soot clings to air filter and heat
exchange elements, disabling them.

Preparing the unit

CAUTION
See "2 Specific installer safety
sure this installation complies with all safety regulations.
INFORMATION
▪ Flexible ducting with sound insulation is effective to
reduce blowing noises.
▪ When selecting installation materials, consider the
required volume of air flow and the acceptable level of
noise for that particular installation.
▪ When room 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 inspection hole to access the inside of
the unit.
▪ The sound pressure level is less than 70 dBA.
