3M™ Under Sink Reverse Osmosis Water Filter Systems 3MRO

Delivering cleaner, clearer, better tasting drinking water.

The 3M™ Under Sink Reverse Osmosis Water Filter System 3MRO is a great option in water filtration – delivering cleaner, clearer, better tasting drinking water. This system is installed under the kitchen sink and provides on-demand filtration for drinking water, coffee, tea, baby formula* and cooking purposes. This under sink reverse osmosis multi-stage filtration system is NSF certified to reduce a number of impurities for improved water quality, taste and appearance. It reduces particulates,* chlorine taste and odor, arsenic, barium, lead, parasitic protozoan cysts, chromium (both hexavalent and trivalent), cadmium, copper, radium, TDS and turbidity. 3MRO501 also reduces nitrates and nitrites.

*Tested and verified by manufacturer’s laboratory.

To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the filter cartridges at the required interval, at the rated capacity or sooner if a reduction in water flow occurs is required. The filter life is dependent on actual use and incoming water quality.

Installation

This reverse osmosis drinking water filter system includes everything needed for most installations, including a polished chrome dedicated faucet, quick-connect fittings, an attached mounting bracket and tubing. Also included is a built-in shut-off valve that allows for changing the Sanitary Quick Change filters. To install the water filter system, you will need a drill (cordless recommended), an adjustable wrench, a Phillips head screwdriver and a razor knife or tube cutter.

For informational purposes only. Please refer to the system manual for complete installation and use instructions. It is recommended this system be installed by a qualified professional.

Steps 1-2: Install dedicated faucet. Relieve water pressure from the cold water line.

Steps 3-4: Install the faucet adaptor. Install the drain connection.

Steps 5-6: Mount the system on the cabinet wall. Install the included filters.

Steps 7-8: Make tubing connections. Turn the water on. Check for leaks.
