Silencer: 

Reduces drive noise by approximately 10dB*. 

Inlet cone: 

When using fan with inlet side open, this cone should be attached to 
maintain performance. 

Inlet screen: 

When using fan with inlet side open, this screen should be attached to 
ensure safety. 

* Degree of sound reduction depends on installation conditions. 

3 Receiving 

3.1  Unloading upon receipt and product verification 

Although each product undergoes thorough inspection and only products that pass inspection are 
shipped, please verify the following points upon receipt of the product: 

*  Fan is as ordered. 
*  No abnormalities such as breakage, deformation, etc. occurred 

during shipment. 

*  All accessories are included. 
*  Bolts and nuts have not loosened. 

3.2 Movement/transportation 

When lifting the fan to move or transport it, always be sure to use the holes labeled "

つり位置

" (Hang 

here) for lifting. For safety, the fan should be lifted by at least 2 labeled hangers (except for products 
with only 1 hanger). Lifting should be performed by licensed personnel only. 

3.3  Storage until installation 

When fan will be stored until installation, even if the storage location is indoors, cover the entire unit 
with waterproof sheeting. (This is also true for outdoor specifications.) Also, to prevent rusting of the 
bearings, etc., turn the impeller about 10 times once per month. If turning by hand, be careful that your 
hand does not get caught. 

4 Installation 

4.1 Mounting 

4.1.1 

Selecting mounting location 

 

The fan should be installed in locations that meet the following conditions: 

  Locations which are within the temperature range where condensation does not occur. 

(Temperature range: -10 to 40°C; Relative humidity: 90% or less) 

  Location where daily inspection and maintenance can be performed easily. 

  Indoors where rain water will not fall on it. 

  Stable location which is not subject to vibrations.
