SAFETY INFORMATION
Read, understand, and follow all safety information contained in these
instructions prior to the use of this 3M
Retain these instructions for future reference.
Intended Use:
This Liqui-Cel Membrane Contactor is intended to add to or remove
dissolved gases from non-dangerous liquid streams. It is expected that all
users be fully trained in the safe operation of membrane contactors.
Membrane contactors are intended for installation and operation by
qualified installers and operators in accordance with all operating
guidelines, installation instructions, and any other industry requirements.
Use in any other application may not have been evaluated by 3M and may
lead to an unsafe condition.
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.
• 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.
CAUTION
To reduce the risks associated with environmental contamination:
• At the end of useable life, dispose of the membrane contactor or cartridges
in accordance with local regulations and laws.

EXPLANATION OF SIGNAL WORD CONSEQUENCES
EXPLANATION OF SAFETY AND RELATED SYMBOLS
NOTICE
• The membrane contactor(s) should not be stored where they are exposed to
direct sunlight. Membrane contactors should always be stored in sealed bags
or shrink wrap material and in the original box or other opaque box.
• Store dry membrane contactor(s) at temperatures < 49° C (120° F) with low
to moderate humidity levels (<60% relative humidity).
• Avoid contact with surfactants/solvents or oxidants (e.g. ozone, chlorine) to
prevent wet-out or oxidation of the hydrophobic membrane.
• To avoid contamination, gloves are recommended when handling the
membrane cartridges.
• Do not use dope or metal connections to connect to plastic connections of
the membrane contactor.
• Failure to follow any instructions in this guide will void any warranty, if any
exists.
New contactors are shipped fully assembled and do not require cartridge insertion.
However, contactors in the field may periodically require cartridge change-outs. This
document provides guidelines on how to change-out cartridges for 8 x 20-inch
stainless steel membrane contactors.
IMPORTANT: Hollow fiber cartridges are shipped in sealed, plastic covers to protect
the membrane from contaminents. It is recommended that customers DO NOT open
the replacement cartridges until they are ready to install.
IMPORTANT: For customers that perform hot sanitization, it may be necessary to
apply some force to remove the end cap to Cartridge Connector piece from the
cartridge. The old cartridge may be damaged in this process, so be sure a new
replacement cartridge is available before starting the change-out procedure.
Securing the contactor
The end-user/operator is responsible for making sure the contactor is properly
secured before starting cartridge replacement. Be sure the contactor cannot roll, fall,
slide or make any movement that may cause injury, damage the contactor or damage
other system components.
