the Reverse Osmosis drain line. A wet-vented p-trap is
a p-trap that shares a common vent/stack. Attach the
drain line adapter to the p-trap and secure it with the

ADAPTER INSTALLATION
CAUTION:
Using Option D may result
in clogging under adverse conditions and requires
periodic inspection/cleaning by the user.
DO NOT INSTALL THE DRAIN LINE DOWNSTREAM
OF A DISPOSER OR IN A HORIZONTAL PIPE.
Install
the drain line adapter under the sink as shown (parts
included). The baffle tee shown must be installed
to prevent a clog in the Reverse Osmosis drain line.
Route the drain line from the air gap to the drain
line adapter, ensure that there are no dips, loops or
low spots in the line. The drain line adapter should
be aligned vertically so that the hose connection
points upward (the hose connection should never
be allowed to drop below 45
°
from this vertical
position). This installation MAY result in a slight drain
noise in the sink drain when the Reverse Osmosis
system is regenerating. If this happens, simply place
the sink drain stoppers in the strainer to suppress it.
