SAFETY INFORMATION
CAUTION
Read, understand, and follow all safety information contained in these instructions prior to installation and use of the CFSBWF Series Backwashing
Filtration Systems. Retain these instructions for future reference.
Intended use:
The CFSBWF Series Backwashing Filtration Systems are intended for use in reducing undesirable aesthetics in water in commercial establishments
and have not been evaluated for other uses. The system is intended for indoor installations near the entry point of a water line, and must be installed by
qualifi ed professional installers according to these installation instructions.

WARNING
CAUTION
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 or moderate injury and/or
property damage.

Indicates a potentially hazardous situation, which, if not avoided, may result in property damage.
WARNING
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.
To reduce the risk of physical injury:
• Shut off inlet water supply and depressurize system as shown in manual prior to service.
To reduce the risk associated with a hazardous voltage:
• If the electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a suffi cient ground connection
across the fi lter installation piping — refer installation to qualifi ed personnel.
• Do not use the system if the power cord is damaged — contact qualifi ed service personnel for repair.
To reduce the risk associated with back strain due to the heavy weight of the various system components:
• Follow safe lifting procedures.
CAUTION
To reduce the risk associated with skin, eye, and respiratory tract irritation from dust from fi lter media during installation:
• Gravel and several types of fi lter media may be used in this product, depending upon the application. During installation, dust may cause irritation to skin,
eyes, and respiratory tract, and may affect lungs.
• Utilize a NIOSH-approved dust fi lter mask and appropriate eye protection when handling and pouring gravel and fi lter media.
• To request an MSDS relating to this product, call 203-238-8965 or visit the web at http://solutions.3m.com/wps/portal/3M/en_US/MSDS (click MSDS
search). For emergencies, call 800-364-3577 or 651-737-6501 (24 hours).
CAUTION
IMPORTANT NOTES
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use instructions before installation and use of this water treatment system.
• Installation and use MUST comply with existing state or local plumbing codes.
• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).
• Do not install on hot water supply lines. The maximum operating water temperature of this fi lter system is 110°F (43.3°C).
• Do not install systems in areas where ambient temperatures may go above 110°F (43.3°C) or below 40°F (4.4°C).
• Do not install if water pressure exceeds 100 psi. 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.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if over tightening occurs.
• Do not install in direct sunlight or outdoors.
• Mount system in such a position as to prevent it from being struck by other items used in the area of installation.
• Ensure all tubing and fi ttings are secure and free of leaks.
• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.
• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.
• Do not apply heat to any fi tting connected to Bypass or Control Valve as damage may result to internal parts or connecting adapters.
• Install on a fl at/level surface. It is also advisable to sweep the fl oor to eliminate objects that could pierce the brine tank.
To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water fl ow should match arrow on control valve. The Inlet and Outlet of other water treatment
equipment products will vary depending on the control valve brand used.
IMPORTANT NOTES
• Failure to follow instructions may result in leakage and will void warranty.
• Since some media dissolves as it elevates pH level, it will increase the hardness. If your dwelling is equipped with a tankless water heater, the
installation of a water softener may be necessary to prevent the heater coil from plugging.

SECTION 1: BEFORE INSTALLATION
Inspecting And Handling Your Filter:
Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.
Handle the fi lter with care. Damage can occur if dropped or set on sharp, uneven projections on the fl oor. Do not turn the fi lter upside down.
Make Sure Your Water Has Been Thoroughly Tested:
An analysis of your water should be made prior to the selection of your water conditioning equipment. Your dealer will generally perform this service for you,
and may send a sample to the factory for analysis and recommendations. Enter your below for a permanent record.
IMPORTANT NOTE:
Hydrogen sulfi de (H2S) must be tested for at the well site. For accuracy, the sample must be drawn with the pump RUNNING and the test be completed
within ONE minute after the sample is drawn.

There are several different fi lter media which can be used in this fi lter. Each is designed to improve a particular aesthetic problem. NONE OF THEM SHOULD
BE USED TO MAKE NON-POTABLE WATER SAFE TO DRINK. The following descriptions indicate not only what the media is designed to do, but also points out
their limitations.
Neutralizer
NEUTRALIZATION (C or N Media) helps prevent corrosion of copper pipes and plumbing fi xtures by correcting low pH (acidic) water conditions. This process
is similar to adding lime to acidic soil or to taking an antacid. C Media is used for moderate pH correction (pH 6.0 - 6.8). N Media, which dissolves more
rapidly, is used for more extreme conditions (pH 5.5 - 6.0 and as low as 5.0 under certain conditions). Both types of media are consumed during neutraliza-
tion and must be replenished periodically.
IMPORTANT NOTE
Since neutralizer media dissolves as it raises pH, it will increase the hardness. To help protect your water heater from the "scaling effect" of hard water,
a Scale Inhibitor Filter or Water Softener should be installed after the neutralizer.
