1.

 

Servicing the product should be done only by qualified technicians for this type of work. 

2.

 

Make  sure  that  you  know  the  exact  type  of  the  system  fluid.  Act  accordingly  and  comply  with  all  the  relevant 

standards and regulations set for handling this type of fluid. 

3.

 

Before disconnecting the product from the system and before releasing the residual pressure do NOT: 

-

 

loosen or unscrew the product bolts; 

-

 

remove any protection cover; 

-

 

Open any service port. 

4.

 

Before any maintenance or non-regular operation, shut off the Isolation valves and release the residual pressure: 

A.

 

 For control valves with a pressure release outlet, slowly open the pressure release plug or the ball valve and make 

sure that all pressure is released.  

B.

 

 For  control  valves  without  a  pressure  release  outlet,  slowly  unscrew  the  flange  bolts  until  all  the  pressure  is 

released from the valve. 

5.

 

Make sure the control valve is empty of all liquid prior to commencing maintenance. 

6.

 

Remove the product from the line only after ensuring that internal pressure has been released. 

7.

 

Place warning signs around the work area as required by the local standards and procedures. 

8.

 

Inspect the product’s safety stickers and replace any damaged or faded sticker. 

9.

 

Manual cleaning of the product and/or its components using high water pressure or steam should be performed in 

accordance with its specific cleaning instructions, the local standards and regulations and without endangering the 
operator or the vicinity. 

10.
