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. 11. This type of
drain is the preferred over the p-trap drain adapter.
Be sure to provide a 1-1/2" 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.

Drain
To install a remote drain point, complete the follow-
ing steps:
1. Locate the 1/4" red tubing on the Reverse Osmosis
filter assembly. See Fig. 10.
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" 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 28. 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. 11.
Provide a 1-1/2" air gap between the end of the tube
and the drain. See Fig. 11.
