Step B - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the drain water from the
Reverse Osmosis filter. You have two options:
• Install the Drain Adapter included with your unit
As shown in Figures 6 and 7, the drain adapter is installed onto
your sink's drain pipe above the P-trap. This is normally used
for under sink installations.
• Use another existing drain in your home
As shown in Figures 8 and 9, the drain tube from the RO filter
runs directly to an open drain. This is often used for remote
location installations.
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 ADAPTER
(Under sink Installation)
The drain adapter included with your RO system is designed
to fit around a 1-1/2" (3.8 cm) O.D. drain pipe. In the following
procedure, you will install the drain adapter above (upstream
of) the P-trap. See Fig. 6. 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 adapter onto the sink
drain pipe, about 6 inches (15 cm) above the Ptrap (See Fig.
7). Make sure that the Q.C. fitting is toward the direction of the
RO filter.
NOTE: Locate so that the drain tubing from the Reverse
Osmosis filter will run straight to the adapter, with no
dips, loops, or kinks.
2. Using the hole through the drain fitting as a guide, mark the
pipe where a 3/8" (9.5 mm) hole will be drilled (See Fig. 7), and
remove the drain adapter from the pipe.
NOTE: Do not drill through the drain adapter's Q.C. fitting,
as this could damage the o-ring.
3. Drill a 3/8" (9.5 mm) 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 7, and
tighten both sides equally to secure the drain adapter halves
onto the pipe. Do not overtighten.

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. 9. This type of
drain is the preferred over the p-trap drain adapter.
Always be sure to provide a 4 cm 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.

To install a remote drain point, complete the
following steps:
1. Locate the 1/4" (6.35 mm) red tubing on the
Reverse Osmosis filter assembly. See Fig. 8.
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" (6.35 mm) 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
elbow fitting that the drain tube connects to.
Refer to Fig 25. 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. 9.
Provide a 4 cm air gap between the end of the
tube and the drain. See Fig. 9.
