Repeat these steps on the opposite end of the cartridge.
END CAP PREPARATION/INSTALLATION
WARNING
To reduce the risks associated with explosion:
• Only use replacement parts supplied by 3M for this product.
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.
• 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.
NOTICE
• To avoid contamination, gloves are recommended when handling the membrane
cartridges.
There are two options for inserting an end cap. Option 1 is Manual Insertion,
option 2 is Vacuum Insertion. Determine your method of choice and go to that
section.
MANUAL INSERTION
•
(A) Inspect and clean the sealing surface of both end caps.
•
Place L washer around the center nozzle and press it down until it touches
the cap nut.
•
Place the center seal (see Assembly Part "d" on page 3) on the center
nozzle. Press it over the threads and down against the L washer.
Place the center seal washer (thinner washer) over the threads and against
the center seal (see Assembly Parts "e" on page 3). Screw the center seal
nut onto the nozzle. Once it touches the washer,
loosen one turn.
•
(B) Lift the end cap and place the center nozzle into the center tube of the
cartridge. Check the identification marks to ensure the end cap
matches the correct end of the housing.
•
Slowly slide the end cap in until it touches the outer O-ring (lumenside).
Complete this step for both ends of the contactor.
•
Rotate the end cap to align the marks placed on the end cap and the
housing during disassembly.
•
Place the V-Band clamp behind the clamping ridge of the housing. The
clamp will need to remain there until the assembly process is complete.
•
(C) Hook the assembly clips onto the end cap at both ends and adjust
the nut for a secure fit. Repeat this step for the remaining assembly
fixtures.
•
Tighten nuts (2 rotations max at a time) to pull the end cap onto the
cartridge. Tighten in an even manor that will allow the end cap to progress
slowly and evenly. It will be necessary to do the tightening from both ends
of the assembly arms during the installation process.
•
Continue checking the alignment marks on the end caps and housing to
properly align the end caps.
