8 - INSTALLATION INFORMATION AND INSTRUCTIONS
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
illustration purposes. Nylon rod, ball and seat (kit DC97)
may be a possible option later).
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).

steel screwdrive clamps on the large ports.
(Either tubing or solid plug (97002) must be installed at
all times, otherwise leakage will occur out this port).

If metal
clamps are to
be used, do
not over
torque screw
drive clamps -
just snug with
screw driver
Included special
plug (97002) must be
clamped as shown
at all times except
when tubing is used.
Insert plug only to
the stop ring. If not
used, tape plug to
back of coupling for
future use if needed.
Remove small clamp
first, to remove plug or
tubing.

*If necessary to
install as shown, then
side inlet port to be on

be rotated apporx. 45"
in either direction as
best dictated by each
installation site.
