2.For Ventilation
When the product is used (with the damper opened) for ventilation, take such measures as to
ensure sufficient ventilation around the installation location. When ventilation around the product
is not sufficient, hot air discharged through the exhaust port may cause increase in temperature
of the location or fume and gas generated from the sample may fill the space. Be sure to connect
the exhaust duct to the exhaust port to ensure discharge of hot air to the outside. The exhaust
duct is optionally av
ailable and should be ordered separately. See “P. 70 List of Accessories.”
