FOR DRAIN COUPLING, DRAIN-BOA
When installing,
center clamps in
the clamp groove
at all three ports.
Preferred coupling
loction - above
trap inlet nut.
Rotate coupling as needed before clamping.
This coupling depicted before the clamps are installed.
(If large stainless screw drive clamps are used (ref.
Fig.6), their width must be 0.50" (preferred).
3/8" or 1/2" O.D. Polyethylene tubing from air gap
unit or air gap dispensing faucet.

Depicts certain dimensions and marking cut 3/8"
or 1/2" poly tubing square and wet only with water
before inserting to "stop".
(Above Fig. shows partial cutaway of inlet port for

Minimum
overlap at each
end approx.
0.70" (1.78cm).
Cut (B)
2"
This allows at
least 1" above
inlet nut for
removal and
possible trap
replacement if
ever needed.

An option not normally used
but if 1/8" dia. nylon rod is
used, carefully drill 3/32" hole
only thru this pilot hole. (NOT
both sides).
Push tunnel shape end of part
(97001) into tubing, leaving
seat end exposed about 0.1"
(0.25cm).
