CRS AFS Purifier I

Connecting the Manifold

NOTE: Do NOT remove the black plastic covers from the check 

valves until manifold installation is complete! 

 

1. The manifold block must be connected to the gas lines.  

 

   The compression fittings on the block fit 1/8” stainless  

 

    steel tubing (202900) or 1/4” stainless steel tubing 

 

   (202902). If you need to connect the filter to lines of 

 

   another diameter, adapters will need to be installed first.

 

2. Select the bracket, bench-mount (L-shaped) or wall- 

 

    mount (flat), which you intend to use. Use the bracket  

 

   first to mark the holes on the bench or wall where the  

 

   manifold will be mounted. 

 

   The bench-mount bracket can also be attached without  

 

   screws by using the supplied double sided tape (see 

 

   pictures on page 9).

 

 

3.Drill the holes to mount the bracket, either to fit the 

 

  anchors provided or to fit the screws without anchors,  

 

  depending on the requirements. 

 

    • In the case of the Bench Mount II configuration 

 

      (see pictures on page 8), the bracket needs to be 

 

      screwed into place first, before mounting manifold to 

 

      the bracket.

 

4. If it is not already in position. Insert the long hex-head  

 

   screw into the back of the manifold. Fasten one of the  

 

   brackets to the manifold.

 

5. Fasten the bracket to the bench or wall in the correct  

 

   position.
