3M Filtrete 3US-PS01, Installation And Operating Instructions Manual

For Use With Cold Water Only.

NOTE: Remove items from under the sink. Place catch basin there to collect small amounts of water that may run 
out when disconnecting water supply lines.

1.  Turn off cold water supply valve and remove existing water 

supply tubing and/or fitting.

2.  Select and mark a location under the sink that allows access 

for filter change.

3.  Using filter head/bracket as a guide, fasten Filter Head Assembly 

to wall with #2 Phillips mounting screws supplied. 

Mark hole locations so that there is 1 1/2

"

 between the 

screws (see Figure 1), from center of each screw. When 
installed, filter bottom should be at least 2 1/2

"

 from sink 

cabinet floor to facilitate cartridge change. Install screws, 
but only halfway, so you can easily slip the bracket to wall 
before firmly setting screws.

4.  Determine length of tubing required from filter head/

bracket to faucet and from water supply line to filter 
head/bracket by holding tubing in place ensuring it is of 
appropriate length. Do not kink tubing as this will impede 
water flow. If necessary, loop tubing around to avoid it 
being kinked.

Cut tubing straight with a utility knife. (See Figure 2).

5.  Install faucet adapter fitting to faucet. This should be a 

snug fit. 

Do not overtighten.
