1 Gallon Liquid / 8 Pounds Dry Capacity
The Hoss Fertilizer Injector allows you to feed your garden while you water, ensuring a constant
proportion of fertilizer is being administered to your plants. This will save you a tremendous
amount of time and energy by allowing you to water and fertilize simultaneously. The injector
works great with drip irrigation systems because it puts the fertilizer at the roots of the plants
— right where they need it.
CAUTION: Installing your system improperly can cause risk of water contamination and pose
health risks. Do not aach your feeder to a hose bib or sprinkler line that does not have an anti-
siphon device like a back flow preventer. Back flow preventer is not included with system and is
sold separately.
Do not install system into an irrigation main line before a zone valve. Do not install or leave
system under constant pressure (with water on and no flow out of your garden hose or
drip system) or if pressure exceeds 80 PSI. Flush hose aer each use to vent chemicals
and pressure. Empty tank when freezing conditions are present. Limit exposure to UV
whenever possible to extend the life of the components.

ADDITIONAL INSTALLATION NOTES
A back flow preventer (sold separately)
should be installed to use an injection
system per local plumbing codes.
When possible the Hose Bib
Adapter fiing should always be
the last component installed in any
configuration. Timers, filters, and
pressure regulators may be installed
aer the Hose Bib Adapter.
The included Tubing Shut O Valves
(TVLV) may be used to shut o the unit.
These can be installed in the clear and
black tubing at any point. Tubing valves
normally drip under pressure, this will
not aect the operation of the injector.
Injector includes 5  of clear and 5  of black tubing, you may trim tubing to necessary length.
A timer may be installed before or aer the hose bib connector.

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.

PROPORTIONING CAP
STEP 
Add the fully concentrated product and select the
appropriate cap seing based on the manufacturers
recommended coverage rate. Products do not require
dilution or premixing unless using a Flo-Disc or the
manufacturer’s recommendation.
STEP 
Fill the tank with water until all air is out of the tank. The
system will mix the products automatically when the water
is turned on.
STEP 
Screw cap onto the tank and connect tubing to the cap and
Hose Bib Adapter. Cap and tubing connections are color
coordinated,connect blue to blue and green to green. The
tubing slides over the connectors on the Hose Bib Adapter
and into the connector on the cap.
STEP 
Set the flow adjustment on the proportioning cap to Fast
Feed for quick feeding and to Slow Feed to feed slowly every
time you water. You can also feed at these approximate
rates (rates will vary due to product variations)
Slow 1000:1 2/3 tsp. per gallon
#1 500:1 1 1/3 tsp. per gallon
#2 250:1 1 Tbsp. per gallon
Fast 100:1 2 Tbsp. per gallon
TO REFILL
Shut o pressure to tank, remove tubing from the cap,
remove cap from the tanks, pour the water out of the tank
and go to step one above.
TYPICAL COVERAGE RATES
Water Soluble Products - 1 lb per 1000 sq. .
Liquid Products - 2 cups per 1000 sq. .
Hoss Tools does not provide application recommendations for products
not listed on the Hoss Tools website.
IMPORTANT:
The fertilizers sold by Hoss Tools are approved to be
used in the Injector System due to their Greenhouse
Quality. Not all fertilizers meet the same specifications
and should be inspected thoroughly for quality before
using in your injection system.

ADVANCED FEEDING GUIDE
7
The chart below is intended to be used for a reference to assist in calibrating your injection
system to other manufacturers products.
USING THE CHART
The gallons to empty at a given seing indicates the total water that will be mixed with your
concentrated product before the contents are completely used. If you need to figure ounce per
gallon or tablespoons, you would reference the“Gallons to Empty” section of the chart.
EXAMPLE
Fertilizer bag wants you to apply 1 tablespoon of product per gallon of water and you want to
apply quickly. If you use the Fast seing, it will take 75 gallons to empty the tank. You then need
to add 75 tablespoons to the tank, top o with water, and use the Fast seing until the color
runs out. The same example above, but with a Flo-Disc installed, on the Fast seing the tank
would run out in 19 gallons of water. To get 1 tablespoon per gallon, you would need to add 19
tablespoons to the tank and top o with water.
Notes: All feed rates are approximate and not guaranteed by Hoss Tools due to the high
amount of variables resulting from dierences in irrigation system configuration, product
quality, viscosity, and specific gravity. Feed rates and ratios are provided for convenience only.
Injection feeders should be used for general application of liquid and water soluble products
only and are not marketed as a direct replacement for chemical siphon feeders.
For safe fertilizing practices Hoss Tools recommends the plants be fed at half or 50% of the
manufacturers recommended amount for the first application to prevent any damage to the
plants or landscape.

TROUBLESHOOTING
WHAT PRODUCTS CAN I USE WITH THE SYSTEM?
Any liquid or water soluble powder may be used in the system. Water soluble powders do not
need to be dissolved to work in the system. The Injection process dissolves, mixes, and mea-
sures for you. If your product is clear you must add food coloring or dye so the product will be
visible in the clear output tube.
HOW DO I KNOW WHEN THE FERTILIZER IS GONE?
When the system is operating (water flowing) the clear tube will fill with the color of your fer-
tilizer. When the system is operating and the tube is running clear, turn the proportioning cap
seing to fast,if still clear, the system is out of fertilizer.
MY FERTILIZER IS GONE BUT THE TANK IS FULL OF WATER
The Injection system will always be full of fluid since it replaces the product with fresh water
utilizing a patented process to layer the incoming water over the heavier fertilizer solution. This
process is similar to oil on water or whipped cream on gelatin.
HOW DO I KNOW THE SYSTEM IS WORKING?
When water is flowing through your garden hose or drip system, the color from the fertilizer will
completely fill the clear tube. The color depends on the fertilizer or dye color. The color in the
tube may be lighter or darker depending on how much fertilizer was put into the tank and/or the
injection seing selected on the cap. If you have a full tank of fertilizer and do not see color in
the clear tube with the cap set to fast, refer to the Installation and Flow Requirements sections.
MY SYSTEM IS RUNNING BUT THE LINE IS STILL CLEAR
• First check that your system has water flowing and is not just under pressure. The tube will
only show color when the water is flowing.
• Make sure the tank was filled with the proper amount of fertilizer and dye was added if the
fertilizer did not contain a dye. Also, confirm all air was removed from the tank by topping o
with water.
• Check that the included Hose Bib Connector is installed according to the Installation section.
You may need to rearrange your filter, pressure regulator, and/or timer so our injector fiing is
last in the configuration.
• Check the Flow Requirements section to determine if you need a Flo-Disc or that the correct
Flo-Disc was selected.
• If installed in a sprinkler line adjust the ball valve connector (CBV, sold separately) according
to the instructions provided with the connector. If the system was installed in a sprinkler line
and a coupling ball valve (CBV) connection was not used, one must be installed for proper
function.
MY SYSTEM IS FEEDING TOO FAST
Check that you have selected the appropriate feed seing. Also, if using a Flo-Disc during
installation, make sure the proper disc was selected. Any Flo-Disc will speed up the injection
rate of the system. If using a coupling ball valve connection (CBV) for irrigation pipe, make sure
the valve is properly calibrated. Refer to the CBV instruction manual or Hoss Tools website for
further calibration instructions.
