Canter element controlled combination manifold, valve and filter module system

Abstract

A filter module that is attached to a combination manifold and valve system may be replaced by simultaneously shutting off an inlet opening and an outlet opening of the system while releasing a securing member of the system from a securing position. The simultaneous shutting off and releasing are accomplished by rotating a rotatable structural member of the system from a first position to a second position.

       12 . A method for replacing a filter module that is attached to a combination manifold and valve system, the method comprising:
 simultaneously shutting off an inlet opening and an outlet opening of the system while releasing a securing member of the system from a securing position, by rotating a rotatable structural member of the system from a first position to a second position, the securing member having secured the filter module in operational engagement with the system in the securing position; and   removing the filter module from the system for replacement with a replacement filter module, when the securing member is released from the securing position;   wherein rotating the rotatable structural member from the first position to the second position allows for the releasing of the securing member.   
   
   
       13 . The method of  claim 12 , wherein the securing member slides in a direction defined by an axis, about which the rotatable structural member is rotated, for the releasing of the securing member from the securing position. 
   
   
       14 . The method of  claim 12 , wherein the securing member slides generally in a direction defined by an axis, about which the rotatable structural member is rotated, for the releasing of the securing member from the securing position, and then pivots away from the axis for the removing of the filter module. 
   
   
       15 . The method of  claim 12 , wherein rotating the rotatable structural member from the first position to the second position is limited to rotating ¼ of a turn. 
   
   
       16 . The method of  claim 12 , further comprising simultaneously opening the inlet opening and the outlet opening of the system while drawing the replacement filter module into operational engagement with the system, after removing the filter module from the system for replacement, by rotating a rotatable structural member of the system from the second position back to the first position.
