Drip systems with less than 120 gallons per hour (GPH) water flow may require an Flo-Disc
in order to inject solution into the drip system. There are three discs provided in the kit for
these conditions.
NOTE
The Flo-Disc is not intended for pressure reduction and
cannot be used for this purpose. The Flo-Disc will create a
stronger bypass through the tank to speed up injection at
lower water flow rates.
IMPORTANT
You must have colored fertilizer in the injector tank or
food dye to adjust the system. Let the system run for
a few minutes to make sure the fertilizer is not flowing
before installing or changing the Flo-Disc. If there is no
color in the clear tube, the system is not flowing and a
more restrictive Flo-Disc is required for operation.
When using a Flo-Disc, pre-dilute products 3 parts water
with 1 part product (25% Strength).
White Flo-Disc - 120 to 60 gph
Black Flo-Disc - 60 to 30 gph
Red Flo-Disc - 30 to 7.5 gph
STEP 
Estimate your water flow by multiplying the number of
drip emiers on your system by their gallons per hour
flow rating. (If you do not know your water flow you can
use trial & error starting without a Flo-Disc. If no color is
present in the clear line insert a Flo- Disc starting with the
white.
STEP 
Remove the Hose Washer from the swivel nut on the Hose Bib Adapter. For easy removal, use
pliers to grab the O-Ring tab or a plain end screw driver.
STEP 
Push the proper Flo-Disc into the Hose Bib Adapter until it presses firmly against the Flow
Restricter in the center of the Hose Bib Adapter. The water flow will hold the Flo-Disc in place.
STEP 
Replace the Hose Washer and follow steps 2 through 4 in the “Installing your Injection System”
in these instructions.
