Page 4: Safety Precautions
1. Safety Precautions Warning Intake of hazardous gas and installation in a hazardous location are strictly prohibited. This blower does not have an explosion-proof structure. Intake of flammable gas or operating the blower in a location with an explosive atmosphere may lead to explosion due to a spark caused by static electricity or contact with an electric device, metal, etc. - Page 5 Caution When installing piping, minimize the resistance to ducts, pipes, etc., for air to flow smoothly. If the blower is operated with the duct closed, it may enter stall operation status, which may cause the impeller blade to generate abnormal vibration, leading to an impeller damage accident.
- Page 6 The blower cannot take in solid material, dust or liquid. Intake of them may cause an accident resulting in damage. In the case of deceleration by an inverter, etc., a resonance between the main body and a duct around it may cause an increase in vibration or generation of sound at a specific frequency (rotation speed).
