MEMBRANE REPLACEMENT 
 
NOTE: 

Run the system for a short time with the cleaning valve open to relieve internal pressure. This will 

ensure that the spring clamp can be easily removed in step 2 below.

 

 

1.

 

If the End Cap has the freshwater 
product  hose  attached,  remove 
the hose (see Figure 1). 

2.

 

Use the flat blade screwdriver to 
lift the end of the Spiral Ring on 
the End Cap. Pull the Spiral Ring 
off (see Figure 2). 

 
 
 
 
 
3.

 

Remove  the  end  cap  by  pulling 
gently on the hose barb and end 
cap taking care not to destroy the 
hose barb. 

 

NOTE: 

End  caps  may  not  come  off 

easily.  Grasp  the  hose  barb  gently 
and  pull  the  end  cap  off.  It  may  be 
necessary  to  wrap  a  piece  of  cloth 
around the hose barb (to protect it), 
then grasp the base of the barb with 
the channel lock pliers and leverage 
the end cap up and away. 
4.

 

With  the  end  cap  removed, 
gently  pull  the  membrane 
element out the open end of the 
membrane assembly (see Figure 
3).
