4. Installing the Drain Clamp
NOTE: If you have a single-basin
sink with a disposal unit, call
Technical Support for options.
NOTE: Before installing the drain
clamp, check the drain pipes under
the sink for corrosion. Corroded
pipes should be replaced before
continuing with installation.
• Attach the drain clamp to a vertical section of the drain pipe, about 6
inches above the trap. Make sure the opening on the drain clamp is facing
towards the drinking water faucet.
• Using the fitting hole of the drain clamp as a guide, drill a 1/4-inch hole
through one side of the drainpipe.
• Remove the drain clamp from the
drain-pipe and enlarge the hole
with a 3/8-inch drill bit. Use a file
to remove rough edges from the
drilled hole.
• Make sure the black rubber gas-
ket is adhered to the inside of the
drain clamp and place the drain
clamp assembly over the drilled
hole. Look through the hole and
posi-tion the clamp so that the
center of the clamp hole is slightly
higher (about 1/16-inch) than the
center of the drilled hole.
• Tighten the clamp securely.
• Screw the plastic compression nut onto the drain clamp until hand-tight.

Connecting the Faucet to the Drain
This is a gravity drain line. Any loops, kinks or sharp bends must be
eliminated before proceeding. Failure to create a straight line to the drain
may result in reject water leaking through the air gap in the faucet onto the
countertop and below the faucet.
CAUTION
1. Align the larger reject (3/8-inch) black tubing from the faucet with the
compression nut on the drain clamp. Create as straight and smooth a path
as possible with the tubing. Do not kink tube. Cut the tubing squarely below
the nut and remove the internal and external burrs.
2. Loosen the compression nut two complete turns. Insert the black tubing
into the nut until it stops. Tighten with fingers, then tighten 1 to 2 turns with
a wrench.
6. Installation of Mounting Screws
1. If system is being installed under the kitchen
sink, locate it on back or right wall. Make sure
to allow ample space for installation. To change
the filter cartridges, a minimum of 1-1⁄2 inches
of clearance is required under-neath the filter
housings. A minimum of 2 inches of clear-ance
from the left side of the unit is also required or
5 inches from the left bracket mounting screw
hole.
2. Install mounting screws at least 15 inches from
cabinet floor and 7-inches apart.
3. Leave a 5/16-inch space between the head
of the screw and the wall to slip bracket onto
screws.
NOTE: Each section of tubing on the RO Assembly has a cap that must be removed
before inserting tubing. Please remove all cap during installation.
7. Connecting the Faucet and the Drain to the System
1. Locate the reject or drain 1/4” black tubing from the drinking water faucet.
This tube is the smaller of the two. Place a mark on the tubing 5/8-inch
from the end. Moisten the end of the tubing with water and insert tubing
into the quick-connect fitting on the flow restrictor found on the of system
behind the membrane. If tubing is not firmly connected, leaking will occur.
It is important for the tubing to be inserted all the way until the mark is
flush with the outer edge of the quick-connect insert.
NOTE: Tubing may be quickly and easily removed from the fitting if
necessary by pressing the collar around the fitting then pulling the tubing
with your other hand.
2. The blue tube from the bottom of the faucet threaded metal tube is
inserted into the outlet of the post filter. Push the free end of the tubing
into the quick connect fitting.
