3M SF1XX Manuel D’Utilisation

Equipment Start-up Procedure
1.   Turn on incoming water to system.
2.   Pressurize system by rotating the inlet ball valve handle 1/4 turn counter-clockwise to the “ON” position.
3.   Check for leaks.
4.   Use any downstream vent to remove trapped air. 
5.   Flush system in accordance with the Performance Data Sheet for the water filter cartridge.  System is now 

ready to use.

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.

 • The disposable filter cartridge

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

reduction in flow rate occurs.

The water filter cartridge will need to be changed every 6-12 months or when low pressure is indicated on the 
manifold’s pressure gauge, whichever occurs first. Depending on local water quality, you may need to change the 
cartridges prior to the recommended change-out.

1.  Shut off the inlet water by rotating the inlet ball valve 1/4 turn clockwise to the “OFF” position.
2  Depressurize system.
3.  Push tab to release cartridge locking mechanism while simultaneously rotating cartridge slightly to the left.
4.  Using both hands and holding cartridge from the bottom, rotate the cartridge a quarter turn to the left and 

gently pull down. IMPORTANT NOTE: A small amount of water will drain from manifold as cartridge is re-
moved.

5.  Remove sanitary cap from new cartridge. Install cartridge with a quarter turn to the right until cartridge comes 

to a complete stop. 

6.  Remove the small scale inhibitor cartridge by rotating to the left (counterclockwise) until the threads are dis-

engaged. Replace with a new cartridge by rotating to the right (clockwise) until the threads are fully engaged
and snug, regardless of final label orientation. 

7.   Slowly turn the inlet ball valve on the manifold 1/4 counter-clockwise to the “ON” position and check for 

leaks.

8.  Flush system in accordance with the Performance Data Sheet. System is now ready for use.
