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.

 

 

Attach metal screens to the inlets and outlets of fans and 
ducts. 

If ducts are not attached to the inlets and outlets of fans or if the 
ends of the attached ducts are left open, be sure to attach a screen 
to cover the opening. 
If no screen is attached, parts of a person's body or objects may 
get sucked in or sucked-in objects may be blown out, leading to a 
serious accident.

 

 

Do not place your face close to the outlet. 

Small debris, etc. sucked in by the fan may fly out of the outlet at 
high speed. If such objects get in the eye, it may result in loss of 
eyesight. Because of this, do not place your face close to the 
outlet.

 

 

When hanging, be sure to use the holes labeled "

つり位置

(Hang here). 

Hanging by other parts may result in deformation of the fan, or 
cause an accident by tipping over or falling down.

 

 

Do not increase speed using an inverter, etc. 

Doing so increases the centrifugal force and air flow pressure force on the rotator, which may cause 
the impeller to break, burnout of the motor due to excessive loads, etc.

 

Caution

 

 

When planning ductwork layout, plan it so that resistance is 
extremely low and air can flow smoothly through the ducts. If fan 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 fan. Doing so may 
result in deformation of the fan, causing the rotator to come in 
contact with the housing, resulting in a fire or breakage.

 

 

Be sure that there are no objects which may tip over or fall due to 
vibrations or air flow force in the area around fans or ducts. Such 
objects may result in an accident in such cases.
