VI. END CAP ASSEMBLY
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 ASSEMBLY STEPS
End cap connector pieces and O-rings are provided with each cartridge
shipment. Four O-rings (2-124) need to be applied to each end cap to
cartridge connector. One O-ring (2-442) is used on each end cap.
If only one end cap is removed during change-out, then only one O-ring
(2-442) will be used.
Note that the end cap to cartridge connector piece has a short and long
side. The shorter end is inserted into the end cap.
A.
Begin by installing the small o-rings to the end of the end cap to
cartridge connector. There are 4 o-rings for each contactor. Ensure
the o-rings (2-442) are seated compeltely into the grooves on the
end cap to cartridge connector.
B.
Replace the large o-ring (2-442) around the outside rim of the end
cap. Be sure to use the correct o-ring.
C.
Insert the end cap to cartridge connector into the end cap. If
needed a small amount of a 50/50 mixture of water and glycerin
can be applied to the o-rings on the connector.
