Intended use:
The 3MDW101 Drinking Water System is intended for use in fi ltering potable water in homes and has not been
evaluated for other uses. The system is installed at the point of use and typically installed under a sink. System
must be installed as specifi ed in the installation instructions by a qualifi ed professional.
Indicates a potentially hazardous situation, which, if not avoided, could result in
death or serious injury and/or property damage.
Indicates a potentially hazardous situation, which, if not avoided, may result in minor

To reduce the risk associated with choking:
•
Do not
allow children under 3 years of age to have access to small parts during the installation of this product.
To reduce the risk associated with ingestion of contaminants:
•
Do not
use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or
after the system. Systems certifi ed for cyst reduction may be used on disinfected water that may contain fi lterable
cysts. EPA Establishment #070595-CT-001.
To reduce the risk associated with a hazardous voltage due to an installer drilling through existing electric
wiring or water pipes in the area of installation:
•
Do not
install near electric wiring or piping which may be in the path of a drilling tool when selecting the position to
mount the fi lter bracket.
To reduce the risk associated with property damage due to water leakage:
•
Read and follow
Use Instructions before installation and use of this system.
• Installation and use
MUST
comply with all state and local plumbing codes.
•
Protect fi lter from freezing
, remove replacement fi lter when temperatures are expected to drop below 40°F (4.4°C).
•
Do not
install systems in areas where ambient temperatures may go above 110°F (43.3°C).
•
Do not install on hot water supply lines.
The maximum operating water temperature of this fi lter system is
100°F (37.8°C).
•
Do not install
if water pressure exceeds 120 psi (827 kPa). If your water pressure exceeds 80 psi (552 kPa), you
must install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check your
water pressure.
•
Do not install
where water hammer conditions may occur. If water hammer conditions exist you must install a water
hammer arrester. Contact a plumbing professional if you are uncertain how to check for this condition.
• Where a backfl ow prevention device is installed on a water system, a device for controlling pressure due to thermal
expansion must be installed.
•
Do not
use a torch or other high temperature sources near fi lter system, cartridges, plastic fi ttings or
plastic plumbing.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape
only
, pipe dope properties may
deteriorate plastic.
•
Do not
install in direct sunlight or outdoors.
•
Do not
install near water pipes which will be in path of a drilling tool when selecting the position to mount the bracket;
• Mount fi lter in such a position as to prevent it from being struck by other items used in the area of installation
(waste baskets, etc.);
• Ensure that the location and fasteners will support the weight of the system when installed and full of water.
• Ensure all tubing and fi ttings are secure and free of leaks.
• Do not install unit if collet is missing. Contact 3M if collets are missing from any fi ttings.
• The disposable replacement fi lter
MUST
be replaced every 6 months, at the rated capacity or sooner if a notice-
able reduction in fl ow rate occurs.
• Failure to follow instructions will void warranty.
• Allow a minimum of 2.5” (6.4 cm) clear space under fi lter to facilitate fi lter change.
• Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.
