13 - 5 Cautions in installation

Do not use a HRV or an air suction / discharge grille in the following
places.
• Place such as machinery plant and chemical plant where gas, which
contains noxious gas or corrosive components of materials such as
acid, alkali, organic solvent and paint, is generated. Place where
combustible gas leakage is likely.
Such gas can cause fire.
• Place such as bathroom subjected to moisture.
Electric leak or electric shock and other failure can be caused.
• Place subjected to high temperature or direct flame.
Avoid a place where the temperature near the HRV unit and the air
suction / discharge air grille exceeds 40°C. If the unit is used at
high temperature, deformed air filter and heat exchange element
or burned motor result.
• Place subjected to much carbon black.
Carbon black attaches to air filter and heat exchange element,
marking them unable to use.

• Install the anchor bolt (M10 to 12) in advance.
Pass the ceiling suspension fixture through the anchor bolt and
secure the anchor bolt with washer and nut. (Before installation, check
for foreign objects such as vinyl and paper remaining inside the fan
housing.)
• The ceiling suspension fixture is fitted on top of the standard unit. If
the anchor bolt is long, install it on the bottom of the unit. (Be sure to
screw in the removed mounting screw on top to prevent air leakage.)
Install the duct caution name plate properly on the indoor
side (SA·RA) and outdoor side (EA·OA).
