3M SF1XX instruction manual Inlet valve closed, Check shut-off valve position

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.

Cartridge Change-out Procedure

CAUTION

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.

2Depressurize 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.

Troubleshooting

	Inlet valve closed	Check shut-off valve position
No water flow through system
	Filter clogged	Replace cartridge
Not enough water to the	Low incoming water pressure	Check source
downstream application(s)	Filter clogged	Replace cartridge
Short filter life	Temporarily dirty water	Change cartridge or install an
		additional upstream pre-filter.
