8. Operating Procedure

 

 

          Warning

 

1. 

Be sure to confirm that there is no leakage after ventilation.

 

* 

If there is a leak, retighten the bolts and nuts. (See the figure below) 

(Tightening pressure may drop due to the packing properties during product 
transportation and installation.) 
 
 

 

 

 
 

 

 
 
 
 
 
 
 
 

2. 

Do not cause the occurrence of water hammer.

 

* 

Otherwise, the expansion joint may be damaged, causing external leakage. 

3. 

When using high temperature fluid, do not touch the product with bare hands.

 

* Failure to follow this notice may result in burns. 

 
 
 
 

Check for leakage
