OPTION D.
DRAIN LINE ADAPTER INSTALLATION (Fig. 3D)
DO NOT install the drain line downstream of a
disposal or in a horizontal pipe. Install the provided
drain line adapter under the sink as shown.
The baffle-tee or y-connector shown must be in place
(purchase and install if necessary) 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,
which could result in a clogged drain line. The drain
line adapter should be aligned vertically so that the
hose connection points in a direction 45°off vertical.
(See Fig. 3E.) This installation MAY result in a slight
drain noise in the sink drain when the Reverse
Osmosis system is operating. Rotate the Drain Line
adapter tee assembly slowly until noise is minimized.
Generally, 180° opposite the existing horizontal
pipe/baffle-tee is a good orientation.
CAUTION!
DO NOT INSTALL DRAIN LINE ADAPTER
DOWNSTREAM FROM DISPOSER.
When installed, the tubing must not have any dips,
kinks, loops, etc. The tubing must be cut to length
to provide a straight routing from the faucet to the
drain (Fig. 3F). See instructions in the “Filtration
Drain Connection Installation” section for details
and options.
INCORRECT INSTALLATION WILL RESULT IN WATER
BACK-UP IN THE DRAIN LINE, WHICH WILL LEAK AT
THE FAUCET!
