INSTALL A DRAIN POINT AND AIR GAP
(for a 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. 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.
To install a remote drain point, complete the
following steps:
1. Locate the 1/4" red tube and determine whether
it is long enough to reach from the Reverse
Osmosis assembly to the drain point.

2. If longer tubing is required, see parts list in back
of manual and replace the red tube with an
adequate length of 1/4" tubing.
3. Cut one end of the drain tube square.
4. Insert this tube all the way into the red collet
fitting on the Reverse Osmosis filter assembly.
See illustration on page 21.
5. Pull on the tubing to be sure it is held firmly in
the fitting.
NOTE: A flow control insert is located inside the
elbow fitting that the drain tube connects
to. Leave this fitting in place.
6. Route the tubing to the drain point and secure at
the end with a bracket (not included). Provide a
1-1/2" air gap between the end of the tube and
the drain.
