Step 2-Install Reverse Osmosis Drain - Kenmore 625.381560 Owner's Manual

Step 2 - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the reject water from
the Reverse Osmosis Filter. You have two options to
choose from:
• Install the Drain Adapter included with your unit
See Figures 6, 7 & 8. This is used in under the sink
installations. The drain adapter kit is installed onto
your sink drain pipe above the P-trap. See Figure 6.
• Use another existing drain in your home
This is usually used in remote location type installa-
tions. The drain tube from the Reverse Osmosis Filter
runs directly to an open drain. See Figures 9 & 10.
NOTE: Local code may dictate which type of drain
installation is used. Other than local code, either drain
installation types may be used. Consult a plumber if you
are not familiar with plumbing procedures.
INSTALL DRAIN ADAPTER KIT
(Under sink Installation)
In an under the sink installation, you normally use the
P-trap drain adapter. A drain adapter kit is included in
your package. Review the drain adapter kit parts in
Figure 8. The drain adapter is always installed in the
sink drain pipe, above or ahead of the P- trap. See
Figures 6 & 8. Be sure to comply with your local plumb-
ing codes. The drain adapter fits 1-1/2" sink drain pipes.
Other drain pipe fittings, purchased locally, may be
needed in addition to the adapter.
1. Slowly disassemble the sink drain pipe between the
sink P-trap and the sink tailpiece. See Figures 6 & 8.
2. Clean the sink tailpiece to assure a leak-tight fit.
3. Install drain adapter directly onto the sink tailpiece
using the ferrule and nut. Snug the nut, but do not
tighten. See Figure 7.
4. Assemble the drain tubing connector to the drain
adapter using the ferrule and nut. Snug the nut, but
do not tighten. See Figure 7.
NOTE: Locate so drain tubing from the Reverse
Osmosis faucet will make a straight run to the adapter,
without dips, loops, low spots or kinks. See Figure 8.
5. Turn the connector to about 45° (10:00 or 2:00 posi-
tion). See Figure 7. Tighten the nut securely.
6. Assemble the P-trap to the drain adapter, and other
drain pipe fittings as required to complete the drain
run. See Figure 6.
NOTE: If needed, you can cut the unthreaded end of
the adapter to make it fit. Do not cut too short or the
adapter will not make a leak-tight seal with the con-
necting fitting.
7. Tighten all connections, but do not over tighten plastic
connections.
