1. Turn off the cold water supply under 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 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 ¼” white tube to the brass tee by following the steps below:
1. Select an easily accessible area under the sink to
mount system manifold. 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. Allow at least 4 to 6
inches of clearance between the bottom of the filters
and the floor to allow ample space to change filters.
1. On the nipple on top of the tank, apply plumber’s
tape 4 or 5 times 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 ⅜” white tubing to your original
“cut” marks to ensure accuracy. Cut ⅜” white tubing.
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.
Do not connect the other end at this time.

2. Make sure the manfold is level. Mark wall
placement for mounting screws using built-in
bracket on back of manifold.
3. Drill two pilot holes for mounting brackets
using ⅛” drill bit for.
NOTE: Use caution not to drill into
anything beyond the cabinet wall.
4. Insert mounting screws into the wall leaving approximately ⅜” of each screw exposed.
5. Remove the sumps from manifold by turning each sump to the left and pulling down before
hanging manifold on wall. Mount manifold on wall and tighten screws. Do not over tighten.
4. Install the ⅜” white tubing to the tank. Slide the compression nut onto the white tubing.
Slide the plastic sleeve onto the white tube. Place brass insert into the opening of white tube.
