Introduction
•Hydrofuse is a new concept in fertilizing that works with existing irrigation (sprinkler)
systems and automatically dispenses fertilizers to all lawns
and gardens.
•Hydrofuse is a quality patented product made exclusively in
the USA. It is designed to provide many years of reliable use
and requires only minimal maintenance.
•The Hydrofuse system will work with virtually any automatic
commercial or residential irrigation system that uses a Timer
(also called “Controller” or “Clock”).
Precautionary Statements
•This system operates on 110 – 120 volts AC, and uses only 60
watts when running. The power supply is UL listed, and all internal voltages are 24 VAC.
However, never touch any wires or electrical parts when the Power is switched on.
•The Hydrofuse system is designed to virtually use any water-soluble fertilizer. Fertilizers
must completely dissolve in the water. Any solids left in the liquid fertilizer supply container
may clog the pump or supply tubing which will void the warranty and may cause
unpredictable results.
•Please be sure to adhere to all Federal, State and local regulations when installing or using
Hydrofuse products.
The following pages show you how to install the Hydrofuse system. Please follow
this guide in sequence for the easiest and most effective installation.

Back Flow Prevention
Please be sure to adhere to all Federal, State and local
regulations when installing or using
Hydrofuse products. Back Flow valves may be subject to
specific regulations in your area.
Planning out the Installation
When planning out the installation, look at the irrigation system layout from the viewpoint of how it will be
easiest to connect the Hydrofuse system.
Firstly, select the best place to install the Flow Sensor / Injection Point in the irrigation Main Line should be
installed after the sprinkler system backflow device but before the mainline tee’s off to go different directions
and BEFORE the first irrigation valve.
Once this is done, you can then determine the best location for the Hydrofuse machine itself. The Flow Sensor
and Injection Point comes with 20 feet of cable / tubing so ideally mount the machine as close as possible to
the where you will connect to the irrigation main line. The machine needs to be mounted to a wall, and there
should be a 120-volt outlet nearby.
Note: Because the Hydrofuse system uses a Flow Sensor it will work with any number of irrigation zones. It
will sense the actual water flow and precisely inject the correct amount of fertilizer to suit the quantity of
water flowing in each zone.

Preparation
Before you leave to do the installation, make sure you have all the equipment needed. Below is a checklist of
what you will usually need. It may be helpful to check each off each thing before you start.
Note: None of the following is supplied with the machine because the parts required vary depending on
the particular installation.
Tools Checklist
1. Toolbox with all common tools.
2. Spade to dig trench (If needed for your installation).
3. Drill with drill bits, hole saws, etc.
Parts Required for Installation
1. 5 gallons fertilizer solution to fill the machine. Note: It will take approx. ½ gallon to prime the machine
before it will start to operate.
2. Four # 12 screws 1 ½” long to mount box to Garage/House (Tap Cons for Concrete, Wood Screws for
Wooden walls, etc.).
3. Silicone sealer to seal mounting screws on machine.
4. Pipe fittings to connect the Flow Sensor and Injection Point into the irrigation system main water pipe
(Included, covered on page 4)
5. Pipe Sealing Compound to seal the pipe fittings for Flow Sensor.
6. Clips to attach tubing to the side of the Garage/House.
7. Optional: ½” conduit to protect tubing if tube is to run in a position where it could be damaged (not
included but available at Home Depot or Lowes).
Performing the Installation
Note: Before you start, it’s a good idea to mentally go through the whole job making sure that you have everything you
need to complete the whole installation process.
1. Location for the Machine. Pick a good location where you will easily be able to run the injection tubing,
Flow Sensor, and also a 120 V power outlet to plug the system into.
2. Mount to the wall using four 1 ½” long # 12 screws. Use appropriate screws for the material the wall is
made of - wood or masonry. Choose a height that is good for your customer so they can easily operate the
system and use a level to ensure the machine is not at an angle. Tip: If desired the box can be painted to
match the color of a house.
3. Seal the Screws with a small amount of silicone sealer to ensure water does not enter the enclosure.

IMPORTANT: Before continuing turn off the water supply to the irrigation system. When done turn the
water back on.
4. Connect the Flow Sensor and Injection Point into the irrigation main line. This must be downstream of
the backflow preventer and before any of the valves. Often the easiest place to inject is right next to the back
flow valve as shown in some of the pictures next page.
IMPORTANT: The Hydrofuse system must be installed with adequate backflow protection to comply with applicable
Federal, State, and Local Codes.
We supply the Flow Sensor and Injection Point and the common PVC fittings used to connect them into your
main line. Customer is responsible to provide PVC fitting needed to tap into the mainline if PVC supplied fitting
will not adequately provide a mainline tap.
Here are the common fittings that you may need to purchase. Fittings are very cheap and easily obtained from
SprinklerWarehouse.com or local hardware store:

Irrigation Pipe Sizes
Many irrigation systems use a 1” size main line. The Flow Sensor supplied is 1” for this reason. If your main
line is ¾” / 1” / 1¼” you can use the supplied Flow Sensor. For ¾” and 1 ¼” just use a reducer to plumb in the
Flow Sensor. These are included with the purchase of the machine.
Installing the Parts
The Injection Point and Flow Sensor can be plumbed in a number of ways as long as they are fitted in the main
irrigation line, above ground level and downstream of the Backflow Valve. The Injection Point should be
downstream of the Flow Sensor so that fertilizer doesn’t pass through the Flow Sensor.
The Flow Sensor needs to be installed
correctly. Note the arrow which indicates the
direction of flow. The flow is from the
backflow valve, then through the Flow Sensor,
then through the Injection Point.
The Flow Sensor needs to be installed with
the wires facing down. This is so water cannot
enter the switch.

The pictures below show various ways the Injection Point
and Flow Sensor can be plumbed in. Use these pictures as
a guide to help you determine what configuration is best
for the way your irrigation system is laid out.

When assembling PVC fittings use appropriate cement for the type of irrigation tubing you have. PVC plastic
is the most common but there are other types so check what your system has before buying extra fittings and
cement. Follow instructions on cement bottle to ensure correct joints.
5. Fitting the Injection Point –Apply Teflon tape then screw the reducer into the T fitting you installed in
the irrigation main line. Again, apply Teflon tape then screw the grey Check Valve into the reducer and
tighten with reasonable force. Connect one end of the 20’ length of tubing by pushing it firmly onto the end
of the check valve inside the blue band.

6. Route the Electrical Cable – cut the
zip tie holding the electrical cable
and push the plug down through the
grommet at the bottom of the
machine as shown:
7. Run the Injection Pipe and the Flow Sensor to the Hydrofuse unit. It’s best to run them in a piece of ½”
diameter flexible or rigid conduit. This protects them from shovels, weed whackers, etc.
8. Run the Flow Sensor cable - through the hole in the bottom of the electrical enclosure.
Next, run them both through the hole in the bottom of
Hydrofuse unit. From there connect the injection tube to
the right side of the pump. Push the tube firmly into the
pump fitting.
