III.  END CAP REMOVAL 

 

  WARNING

 

  

To reduce the risks associated  with crush or impact related injuries:

•  Always ensure the membrane contactor is properly secured. Be sure the 

membrane contactor cannot tip, roll, fall, slide or make any movement that 

may cause injury or damage to other system components.

•  No liquid, vacuum or sweep gas should be running through the contactor 

when changing cartridges or other parts. Membrane contactors should be 

completely drained of liquid before attempting to service. 

• Care must be taken not to hit or jar (shock) the membrane contactor.

 

  

To reduce the risks associated with lifting or moving:

•  Always consult the product datasheet or operating guide for membrane 

contactor weights. Use appropriately rated lifting equipment for lifting or 

moving heavy membrane contactors. 

•  Drain liquid from the contactor before moving. 

Do not

 move a membrane 

contactor while it contains liquid.

NOTICE

•  To avoid contamination, gloves are recommended when handling the 

membrane cartridges.

END CAP REMOVAL STEPS

A.

 

Begin by removing both retaining clips from the end cap with a  

5 mm hex key.

B.

 

Using pliers (or other suitable tool), pull the tab of the end cap 

retaining clip free. Then, remove the retaining ring from the end cap 

and set aside. Do not discard.

C.

 

Ensure that the screw in the end cap removal tool is inserted all the 

way into the hole so the screw head is flat against the bar.
