heck and comply with local plumbing codes as you plan,
C
then install a cold water supply fitting. Refer to the
Specifications page for supply water requirements. The fitting
must provide a leak-tight connection to the RO 1/4" tubing. A
typical connection using the included water supply fitting is
shown in Figure 6. An optional connection using standard
plumbing fittings (not included) is shown in Figure 6B.
NOTE: Local code may dictate which type of water fitting is used. Consult a plumber if you are not familiar
with local codes or plumbing procedures.

(Included)
This fitting will be installed on the cold water pipe. The fitting
must provide a leak-tight connection to the Reverse Osmosis
1/4" tubing. Locate the cold water line in the sink cabinet. It
is recommended, but not required, that the cold water line be
soft water.
Complete the following steps to install the water supply fitting.
1. Close the hot and cold water shutoff valves under the sink
where the cold water supply fitting will be installed, and
open faucet(s) to relieve pressure.
2. Disconnect the existing cold water line from the water
shutoff valve.
3. Make sure that the water supply fitting’s gasket is inside
the female threaded portion of the fitting.
4. Install the water supply fitting onto the cold water shutoff
valve, where the existing cold water line was removed,
and hand tighten. Be careful not to cross thread or overtighten.
5. Connect the existing cold water line to the male threaded
portion of the water supply fitting and hand tighten. Be
careful not to cross thread or overtighten.

Step B - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the drain water from
he Reverse Osmosis filter. You have two options:
t
• Install the Drain Adaptor included with your unit
As shown in Figures 7-9, the drain adaptor is
nstalled onto your sink’s drain pipe above the P-trap.
i
This is normally used for under sink installations.
• Use another existing drain in your home
As shown in Figures 10 and 11, the drain tube from
the RO filter runs directly to an open drain. This is
often used for remote location installations.
NOTE: An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
NOTE: Local code may restrict the type of drain
installation to use. Either drain installation type, if
permitted by code, may be used in under sink or
remote location installations. Consult a plumber if
you are not familiar with plumbing procedures.
INSTALL DRAIN ADAPTOR
(Under sink Installation)
The drain adaptor included with your RO system is
designed to fit around a standard 1-1/2” O.D. drain
pipe. In the following procedure, you will install the
drain adaptor above (upstream of) the P-trap. See Fig.
7 & 9. Be sure to comply with local plumbing codes.
NOTE: Before starting this procedure, inspect the
drain pipe under the sink for corrosion, and replace
if necessary, before continuing with installation.
1. Test fit the two halves of the drain adaptor onto the
sink drain pipe, about 6 inches above the P-trap
(See Fig. 8). Make sure that the Q.C. fitting is
toward the direction of the RO faucet (See Fig. 9).
NOTE: Locate so that the drain tubing from the
Reverse Osmosis faucet will run straight to the
adaptor, with no dips, loops, or kinks.
2. Using the hole through the drain fitting as a guide,
mark the pipe where a 3/8” hole will be drilled (See
Fig. 8), and remove the drain adaptor from the pipe.
NOTE: Do not drill through the drain adaptor’s
Q.C. fitting, as this could damage the o-ring.
3. Drill a 3/8” dia. hole in the pipe and remove flash.
4. Clean the sink tailpiece to assure a leak-tight fit.
5. Place the halves of the drain fitting back onto the
sink drain pipe. Use a pencil or similar pointed
object to align the Q.C. fitting so that it is centered
on the hole you drilled.
6. Assemble the nuts and screws, as shown in Figure
9, and tighten both sides equally to secure the drain
adaptor halves onto the pipe. Do not overtighten.
7. Do not connect black tubing to the Q.C. fitting at this
time. It is done after the RO faucet is installed.

INSTALL A REMOTE DRAIN POINT
AND AIR GAP (Remote Location)
Route the drain tubing to an existing drain in the house.
A floor drain, laundry tub, standpipe, sump, etc. are
suitable drain points. See Fig. 11. This type of drain is
the preferred over the p-trap drain adapter.
Always be sure to provide a 1-1/2” air gap between the
end of the hose and the drain point. This will prevent
water from backing up into the system.
NOTE: Check your local plumbing codes.

FIG. 11
To install a remote drain point, complete the
following steps:
1. Locate the 1/4” red tubing on the Reverse Osmosis
filter assembly. See Fig. 10.
2. Determine if this length is long enough to reach the
drain point. Longer lengths of tubing (see parts list in
back of manual) may be needed.
3. If longer tubing is required, disconnect the 1/4” red
tubing and replace with an adequate length of tubing
to reach the drain point. Refer to Step F later in the
manual on how to disconnect and connect tubing.
NOTE: A flow control insert is located inside the
fitting that the drain tube connects to. See No. 12
on page 22. Leave this fitting in place.
4. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 11.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 11.
