4. How to Use 

 

Air flow adjustment method (for the air curtain type only) 

①

 Measure the air flow at the blow port of air curtain. 

Run exhaust and fan blowers with the operation key and open the door fully.    Provide 

a  guide  plate  of  about  100  mm  at  the  blow  port.    Divide  the  opening  into  five  equal 

portions and measure the air flow in a center of each of these portions with a wind speed 

indicator.

②

 From the average of air flow values obtained from five points, calculate the air flow using 

[Formula 1] and compare the calculated value with the standard supply air flow (Page 

41) for each type.    When the air flow thus calculated deviates from the standard value, 

adjust it with a damper handle of the ceiling supply duct.
