Liqui-Cel
™
MM 0.5x1 and 0.75x1 Series
Membrane Contactors
Prior to any start-up procedure, proper installation is required.
Please read and follow all safety information, warnings and instructions in this manual. Failure
to follow all product warnings and instructions could cause serious injury and property
damage. Retain these instructions for future reference.
Intended Use and Product Selection:
3M™ Liqui-Cel™ Membrane Contactors are intended to remove dissolved gasses and bubbles
from compatible liquids or to add gasses to a liquid stream. Liqui-Cel products are for use in
industrial separation applications of industrial fluids only, in accordance with the applicable
product instructions and specifications. 3M Liqui-Cel MM 0.5x1 and 0.75x1 Series Membrane
Contactors are not constructed of US FDA Title 21 CFR § 174-186 compliant materials. Not for
use in food contact applications.
Since there are many factors that can affect a product's use, the customer and user remains
responsible for determining whether the 3M product is suitable and appropriate for the user's
specific application, including user conducting an appropriate risk assessment and evaluating
the 3M product in user's application.
Restrictions on Use:
3M advises against the use of these 3M products in any application other than the stated
intended use(s), since other applications have not been evaluated by 3M and may result in an
unsafe or unintended condition. Do not use in any manner whereby the 3M product, or any
extractable or leachable from the 3M product, may become part of or remains in a medical
device, drug, cosmetic, or food or drink additive or supplement; or in applications involving
life-sustaining medical applications or prolonged contact with internal bodily fluids or tissues. If
you are considering using this 3M product for a restricted use, you must first contact 3M with
information about your proposed application to request prior written authorization for supply.
If your process may result in dangerous concentrations of explosive, flammable, toxic or
oxidizing liquids or gases in the membrane contactor or the system, contact 3M prior to use.
SAFETY INFORMATION
Explanation of Signal Word Consequences
WARNING
Indicates a hazardous situation which, if not avoided, could result in serious injury or death.
NOTICE
Indicates a situation which, if not avoided, could result in product or system damage.
Read entire product manual. Failure to follow all product instructions and warnings could cause personal injury and/or
property damage.
WARNING
–
To reduce the risks associated with liquid bursting or gas explosion and/or exposure to chemicals and
membrane contactor damage:
• To prevent buildup of pressure inside the membrane contactor, do not block or valve off all gas/vacuum ports during
operation or downtime.
• Do not exceed maximum operating pressure or temperature limits. Cleaning should be conducted at the minimal temperature and
pressure required to clean the contactor, never exceeding the maximum operating pressure and temperature limits of the contactor.
• Implement workplace safety risk controls according to local applicable laws and regulations.
• Always use appropriate personal protective equipment (PPE) when installing, servicing, operating, cleaning or disposing of
the membrane contactor.
To reduce the risks associated with fire and explosion:
• Do not introduce explosive, flammable, toxic or oxidizing liquids or gases in dangerous concentrations into the membrane
contactor or the system.
NOTICE
– To reduce membrane contactor or system damage:
• Care must be taken not to drop, hit or impact the membrane contactor.
• If the membrane contactor is used with air sweep, then the temperature should not exceed 35°C (95°F). For membrane
contactors used with vacuum only this statement does not apply.
• To avoid contamination of the process fluid, gloves are recommended when handling the membrane contactors.
• 3M Liqui-Cel Membrane Contactors should be stored dry and in a sealed plastic bag or shrink wrap material to help
prevent the introduction of contaminants into the membrane contactor.
• 3M Liqui-Cel Membrane Contactors should be stored in their original box, or other opaque box, and should not be installed
where they are exposed to direct sunlight.
• Store 3M Liqui-Cel Membrane Contactors dry at temperatures < 50°C (122°F), but preferably at lower temperature such
as <35°C (95°F), to not risk reduced lifetime. Membrane contactors should always be stored above freezing temperatures,
and if stored at low temperature, they should be allowed to equilibrate to room temperature before use.
• Do not allow membrane contactors containing microporous hollow fiber membranes to come into contact with surfactants,
oil, or organic solvents, such as pure alcohols, glycol, acetone, etc., to reduce the risk of membrane wet out. SP-series
membrane contactors containing polyolefin membrane are not subject to this restriction.
• Filtered, de-chlorinated, and deionized water is recommended for mixing cleaning solutions. If a pH shift occurs, water
containing sparingly soluble compounds of Ca, Mg, Fe, Al, and silica (SiO2) etc. could precipitate from the solution and
block or damage the membrane. Ensure that your water is free of these compounds.
• Cumulative exposure of the membrane to oxidants, such as ozone, chlorine, hydrogen peroxide, peracetic acid, etc., should
be restricted to reduce the risk of membrane oxidation.
ATTENTION:
Disposal
At end of life, dispose of the membrane contactor or cartridges in accordance with all applicable local and government regulations.
Hazards from Chemicals
The chemicals that User selects to use in connection with the membrane can present their own hazards. User should follow all
safety information and related requirements provided by the chemical supplier and applicable regulations, as well as conduct
User’s own workplace safety, hazard and application assessment. This document cannot and does not address all safety and/
or safe handling requirements that different chemicals could present. User is responsible for ensuring that chemicals are only
used by persons familiar with their use and hazards (for example, personnel who have received hazardous material training),
and who have the appropriate protective equipment as specified in their organization’s safety program and the chemical’s
safety datasheet (SDS). User assumes all responsibility for the suitability and fitness for use as well as for the protection of the
environment and for health and safety involving such chemicals.
Product Selection and Use:
Many factors beyond 3M’s control and uniquely within user’s knowledge and control can affect
the use and performance of a 3M product in a particular application. As a result, customer is solely responsible for evaluating
the product and determining whether it is appropriate and suitable for customer’s application, including conducting a
workplace hazard assessment and reviewing all applicable regulations and standards (e.g., OSHA, ANSI, etc.). Failure to
properly evaluate, select, and use a 3M product and appropriate safety products, or to meet all applicable safety regulations,
may result in injury, sickness, death, and/or harm to property.
Warranty, Limited Remedy, and Disclaimer:
Unless a different warranty is specifically stated on the applicable 3M
product packaging or product literature (in which case such warranty governs), 3M warrants that each 3M product meets
the applicable 3M product specification at the time 3M ships the product. 3M MAKES NO OTHER WARRANTIES OR
CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OR CONDITION OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR ARISING OUT OF A COURSE OF DEALING, CUSTOM, OR
USAGE OF TRADE. If a 3M product does not conform to this warranty, then the sole and exclusive remedy is, at 3M’s option,
replacement of the 3M product or refund of the purchase price.
Limitation of Liability:
Except for the limited remedy stated above, and except to the extent prohibited by law, 3M will not
be liable for any loss or damage arising from or related to the 3M product, whether direct, indirect, special, incidental, or
consequential (including, but not limited to, lost profits or business opportunity), regardless of the legal or equitable theory
