Installation 

Important

 

  

 

1) Select a location where the typical temperature and 

humidity of the measured fluid can be sensed and 
where the wind speed requirements are met. 

2) Make sure that the temperature and humidity elements 

are entirely immersed in the measured fluid.    Also, 
make sure that air can pass over the side of the 
sensor. 

3) Allow adequate service clearance at the front of the 

cover. 

4) When installing in steam heating air handling unit, 

make sure the steam does not directly expose.    (It 
may exceed the extreme operating condition.)   

5) When inserting the insertion part facing upward, 

prevent dew condesation.    (The condensated dew will 
remain in the fileter cap and measurement difference 
will occur until it becomes dried.)   

 CAUTION 

 

Do not step on the unit. 

 

Mounting 7803 series (duct mounted) 

1) Prepare the mounting bracket in advance. 

Attach the mounting label at the sensor mounting 
position and make a hole in the duct at the point 
indicated on the label. Fix the mounting bracket onto 
the duct with M4 screws, inserting packing between 
the duct and the bracket. 
Cover the duct with an insulating material. (If you cover 
the duct with an insulating material first, fill the 
clearance between the bracket and the duct with the 
insulating material after fixing the bracket.) 

 
2) Turn the stopper of the main unit to the left and insert 

the main unit into the bracket, aligning the claw to the 

bracket groove.    Fix it by turning the stopper 45 ° in 
the clockwise direction. 

 

 

Mounting 7813 series (air handling unit 
mounted) 

1) Prepare the mounting bracket in advance.    Attach a 

mounting label at the desired mounting position and 
make a hole in the air handling unit return air chamber.   
Fix the mounting bracket onto the duct with M4 screws 
(included) between the duct and the bracket. 

2) Turn the stopper of the main unit to the left and insert 

the main unit into the bracket, aligning the claw to the 
bracket groove.    Fix it by turning the stopper 45 ° 
clockwise.
