Step 1
From the parts bag locate:
Drain saddle assembly and the 1/4” x quick connect fitting that is needed for the application
For use with a non-air gap installation: use (smaller) 1/4” quick connect fitting x 1/4” mpt
For use with an air gap installation: use (larger) 3/8” quick connect fitting x 1/4” mpt
Step 2
Place the drain saddle but do not tighten. Placement of drain saddle should be located on the vertical tail piece
of the plumbing system at least 2” above the horizontal outlet or trap assembly.
NOTE: On the vertical pipe:
The higher the placement on this pipe, the greater the chance of increased noise in your waste line. Drain
connection should be pointing out or towards you as you look into the cabinet.
On the horizontal pipe as an alternate location:
See illustration A, the drain saddle should be at a 10 o’clock or 2 o’clock position
Step 3
Once the drain saddle is placed, use a 1/4” drill bit, and drill a hole slightly above the drain saddle. Do not drill through
the other side of the pipe. Make sure the one hole is complete with clean edges and clear of debris.
WARNING:
IF DRILLING METAL PIPE, PROTECT YOURSELF FROM SERIOUS INJURY OR FATAL SHOCK, USE A HAND DRILL
OR A CORDLESS DRILL TO MAKE THE HOLE. IF YOU USE AN ELECTRIC DRILL, OUTLET MUST BE GROUNDED.
USE SAFETY GLASSES OR OTHER EYE PROTECTION WHEN GRINDING TO PREVENT POSSIBLE EYE INJURY
DUE TO FLYING PARTICLES.
Step 4
Loosen drain saddle and slide over the 1/4” hole. Make sure the hole in the drain pipe is aligned with the hole in the
drain saddle. Tighten drain saddle using a screwdriver, alternating sides for even tightening.
Step 5
Using Teflon tape (not included) wrap 1/4” male threads on 1/4” x quick connect fitting (selected for air gap or non-air
gap application) using clockwise motion for at least three revolutions. Hand tighten fitting clockwise into drain saddle.
Caution: Do Not Overtighten.
When installing drain saddle on a
horizontal pipe (thats’ the one that goes
across shown in dark)
Install connection at the 10 o’clock or 2
o’clock position (as illustrated to the left)
This allows for the proper flow of RO
drain rejection water and will help to
prevent any cross-contamination.
WARNING:
Avoid mount off the garbage disposal
drain pipes.
