Safety precautions Warning Intake of dangerous gases or installation in dangerous locations is prohibited. This product does not have an explosion-proof structure. Intake of flammable gases or operation in an explosive atmosphere may result in an explosion caused by sparks due to static electricity, electrical devices, metal contact, etc. - Page 5 Caution When planning ductwork layout, plan it so that resistance is extremely low and air can flow smoothly through the ducts. If blower is operated with duct shaped so that it is blocked, it may result in stall operation. Abnormal vibrations due to stall operation may cause impeller blades to be broken Do not transfer the load of the ductwork to the blower.
