1 — INSTALL BRASS TEE FITTING
1
Turn off the cold water supply to the sink.
2
Turn on the kitchen faucet to release pressure and allow water to drain from the line.
3
Disconnect the cold water line from the 1/2" threaded stem on the bottom of the kitchen
faucet. Attach threaded ends of supplied brass tee to the cold water supply line and shut-off
valve; tighten using an adjustable wrench.
4
Attach 1/4" white tube to the brass tee:
A. Slide the compression nut onto the white tubing.
B. Slide the plastic sleeve onto the white tube.
C. Place brass insert into the opening of white tube.
D. Push the tip of the white tubing into the opening of the brass tee.
E. Slide the compression nut onto the threads of the brass tee.
F. While holding the white tube in place, tighten the compression nut to compress the plastic
sleeve and create a seal.
NOTE:
Use a wrench to ensure complete seal. Avoid over tightening.
5
Do not connect the other end at this time.
1
On the nipple on top of the tank, apply plumber’s
tape 4 or 5 times clockwise around in the same
direction as the threads.
2
Hand tighten the tank connector onto the tank
nipple until secure.
NOTE:
Do not cross thread or
over tighten.
3
Using mount stand, place tank near the system
manifold. Measure 3/8" white tubing to the outlet
side of the system manifold and ensure you
have enough tubing to connect tank and system
manifold as well as enough left to attach faucet
stem and manifold. Cut 3/8" white tubing.

2 — INSTALL SYSTEM MANIFOLD
1
Select an easily accessible area under the sink to mount system
manifold. You want to allow at least a 4 to 6 inch clearance
below the filters to the floor to allow ample space for filter
changes. To help gauge the right location for your system
manifold, insert first and third stage filter sumps into manifold.
Insert sumps by aligning top connection points and push up and
to the right until sumps are locked in.
2
Mark wall placement for mounting screws using
built-in bracket on back of manifold. Make sure holes
are as level as possible.
3
Drill two pilot holes for mounting brackets using 1/8"
drill bit for the system manifold.
NOTE:
Use caution
not to drill into anything beyond the cabinet wall.
4
Insert mounting screws into the wall leaving
approximately 3/8" of each screw exposed.
5
Remove first and third filter sumps from manifold by turning each sump to the left and
pulling down before hanging manifold on wall. Mount manifold on wall and screw in. Be
careful not to over tighten.
4
Install the 3/8" white tubing to the tank:
A.
Push the tubing through the nut, collar and sleeve into the connector.
B.
Unscrew the compression nut from the tank connector to ensure that the tubing is
connected all the way through the collar and sleeve.
C.
Slide the nut to the threads and tighten with a wrench. Avoid over tightening.
