Installation Instructions

FILTRATION DRAIN CONNECTION (cont.)

PREFERRED INSTALLATION: OPTION C—WET-VENTED P-TRAP INSTALLATION

Install a p-trap under the sink to be used exclusively for 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 slip joint nut and washer as shown. The drain line MUST be routed through the air gap provided in the RO water faucet. Locate the Reverse Osmosis p-trap as high as possible (minimum of 4” above horizontal).

Optional disposer

SECONDARY INSTALLATION: OPTION D—DRAIN LINE 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, ensuring 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.
