3M SF1XX User Manual

 

• Failure to follow instructions may void warranty.

 • Allow a minimum of 3” (7.6 cm) clear space under filter to facilitate cartridge change.
 • Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.
 • Some local codes may require the use of a licensed plumber or certified installer when disrupting a potable

water line.

SF1XX High Flow series water filtration systems combine chlorine taste and odor reduction with particulate 
reduction, and help protect equipment from the potentially harmful effects of scale formation, even at application 
temperatures to 200°F (93°C). The inlet water enters the manifold on the left rear side and exits through the scale-
inhibitor feeder on the right front side. The capacity of the system is equal to the flow rate and capacity rating for 
the filter cartridges used.

The water inlet is on the left rear side and the outlet is on the right front side. These are identified with labels. The 
fitting size is 3/4” NPT (Male). A built-in check valve (non-return) is incorporated into the outlet.

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 from freezing, remove filter cartridge when temperatures are expected to drop below 40°F (4.4°C);

 

• Do not install on hot water supply lines. The maximum operating water temperature of this filter system is 

100°F (37.8°C).

  •

Do not install if water pressure exceeds 125 psi (862 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.

 • Any non-metallic fittings used in the installations must be of adequate rating for the line pressure.
  •

Do not use a torch or other high temperature sources near filter system, cartridges, plastic fittings or plastic  

       plumbing.
 • On plastic fittings, 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 fittings, as damage may occur if overtight-

       ening occurs.
  •

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 filter in such a position as to prevent it from being struck by other items used in the area of installation.
 • Ensure that the location and fasteners will support the weight of the system (Approx. 10.5 lbs [4.8 kg]) when

installed and full of water.

 • Ensure all tubing and fittings are secure and free of leaks.
 • The disposable filter cartridge

MUST be replaced every 12 months or at the rated capacity or if a noticeable   

        reduction in flow rate occurs.
