Fertijet – enhanced fertigation machine
User manual
1. General Description
Fertijet is a compact, simple and modular fertigation control
system for use in both greenhouses and open field irrigation
applications.
Fertijet is designed for accurate injection of nutrients into the
irrigation water pipe through a set of Venturi type fertilizer
injectors under EC & pH control and optional irrigation
control by the advanced Elgal computerized controller.
Fertijet can be fitted quickly and easily on almost any
irrigation head.
1.1 System Components
A standard Fertijet unit consists of the following components:
• A set of 3 Venturi type fertilizer injectors with a flow rate
of up to 90 GPH each. Each injector contains an electric
fertilizer control valve, an adjustable flow regulator, and a
flexible suction pipe.
• A water pump (1.5, 2.5 or 3 H.P.) with a stainless steel
head, to obtain a flow of water through the fertilizer
injectors and insert the solution into the water pipeline.
• An EC & pH monitor unit, consisting of a transmitter with a 4-20 mA output, galvanic
insulation, a large LCD display and a four-button keyboard for soft calibration.
• A pair of EC & pH electrodes, installed in a sampling cell.
• An Elgal irrigation/ fertigation controller.
• An electrical control panel, also including connection terminal blocks.
• An inlet and an outlet for irrigation water.
1.2 Safety Instructions
¾Before installing and connecting the Fertijet in place, read the “Pre- Installation” manual
carefully and follow all the instructions applicable to Fertijet.
¾To install the Fertijet and associated equipment, follow NFPA 70 directives strictly.
¾Have high voltage (> 60V) electrical connections made only by a local, qualified electrician.
¾Do not operate the Fertijet before ensuring full connection to a valid grounding point (1Ω or
lower).
¾Before removing the electrical box cover, shut the main power switch Off.
¾Before attempting any maintenance work on the booster pump, shut the main power switch
Off.

Procedure
(1) Unpack the Fertijet and rest it on a solid base. Mount the I/O box on a solid wall or post.
(2) Connect the 32mm inlet and outlet pipes to the mainline as shown above.
(3) Connect the blue pipe (water sampling for EC and pH sensor measurements) to the main
irrigation line at a point at least 1.5m (4 feet) downstream from Fertijet’s outlet connection.
Note that the exact recommended distance depends on the water flow speed in the main
pipe. For more accurate calculation, use your Internet browser to refer to the URL:
ftp://ftp.eldarshany.com/pub/literature/fert_calc.xls
(4) Open the EC-pH sampling cup and remove the pH sensor cover.
Fill the sampling cup with water and mount it back in place.
Important: The pH sensor must be immersed
in water at all times.

Connect the pipes from the fertilizer tanks to the fertilizer injector inlets: Fertijet default
settings define Injectors #1 and #2 as nutrients injectors (EC injectors allowing correction
of quantities according to conductivity) and Injector #3 as an acid injector (pH injector
attempting to maintain pH stability). For a different configuration (e.g. two acid injectors
and one fertilizer),change the settings in menu screen no. 5216.
2.2 Wiring
Power Supply Connections
(1) Booster pump power connection:
Have a local, qualified electrician connect the booster pump load according to the marking
sticker at the end of the HD (green) cable.
(2) Controller and communication connection:
Plug the controller and communication (white) cable to the local mains using a connection
box (not a wall socket!). Verify that this power point is protected by a 6A circuit breaker.

3. Irrigation System Setup
Each system is uniquely characterized by own water meter pulse, valve flow rates, fertilizer types
and settings. All of these parameters are necessary for system operation and must be
programmed on the site before the first operation. To set system parameters, follow instructions
as applicable to the program used (see table below):
Fetijet with 1CL_IR Software (Elgal 12/24)
Follow the instructions on “Irrigation software”
manual page I2-1 and top of page I2-2. Fertijet
may be used either as a “standard” system when
applied to the entire irrigation system or as “FertOnly” system when applied to the fertigation
system alone.

4.3 Fertigation Automation Adjustment
This chapter is intended to clarify some special features of Fertijet, which are not explained in the
Elgal manual. Please read the complete irrigation chapter in the Elgal manual to better
understand the fertigation method of the Elgal controller.
Description
Fertijet does not pre-set the point where the EC-pH sample is taken. This decision is left to the
technician who installs the machine. This point and the length of the pipe to the sampling cell
both have a considerable effect on the fertilizer automation function. When the program changes
the water-to-fertilizer ratio, a timer is set to define the minimum time to the next change (if
required). This function serves to identify the impact of the last change as soon as possible, then
make the next change. Performing the second change before reading the results of the first one
would cause overshooting, and the EC and pH may never become balanced. On the other hand, a
slow reaction is not desirable either.
Calculating the shortest response time is not an easy task. If you have Internet access, you can
find an on-line calculator for that purpose at:
ftp://ftp.eldarshany.com/pub/literature/Fert_Calc.xls (“Fertijet balancer” sheet). All you have to
do is type your application details in the appropriate cells, and the calculator will come on with
the results.
If you do not have access to the Internet, use this formula:
Rt = ht + dt + Dt + 3
where:
SQ – the flow of the smallest shift in the irrigation system
D – the internal diameter of the main pipe
Dl – the distance between the fertilizer insertion point and the sampling outlet in the main pipe
(cm)
Dt – the delay time in the main pipe; Dt = (((D / 2)2 * π) * Dl) / SQ
dl – the length of the 32mm pipe from the Fertijet outlet to the main pipe (m)
dt – the time in the 32mm pipe (sec); dt = dl / 13.9
hl – the length of blue sampling hose (m); ht = hl / 0.4

Fertimix User´s ManualFertijet Manual
ht – the time in blue sampling hose (sec)
Rt – the response time required
Dl
Fertijet
dl

Figure 8: Rt Calculation
Notes
¾Calculation as above may be problematic since different units are used in different countries.
¾The last 3 seconds added to the calculation represent probe’s response time.
¾“dl” is subject to many changes as may be caused by line pressure, pump model (MXH 405
or 805), number and type of Venturi pumps, and even fertilizer valves position (on or off).
However, as you will find when you do the calculation, as long as you do not install the
Fertijet at a distance greater than one or two meters from the insertion point, the effect on the
calculation would be negligible.
Procedure
(1) Calculate shortest response time (Rt) as above.
(2) Save calculation result under the respective parameter in the controller. To save, press
<5241> and <R> on the controller panel or (for PC users) click <settings>, <Irrigation>,
<Fertigation setup>.
The text displayed on the panel will be “Change fert. Delay – sec.”, with a default value 8.
Enter calculation result, then press <Enter>.
(3) Move to the next parameter. The text displayed will be “Delay at start – sec.”, with a
recommended value two and a half times the change delay. Press <Exit>.
(4) You will now be prompted to save the last changes. Press <Enter> to confirm the default
setting, or, if you use a PC, click the key icon and change the desired parameters.
A second click on the key icon will send your changes to the controller after confirmation.

5.2 Winterizing
Winter time in frost- ridden areas may prove quite harmful to all irrigation components if not
duly prepared. The following steps will guide you in safe winterizing. Follow them strictly.
When to Winterize
The best time to winterize is the morning after the last day of the irrigation season.
Procedure
(1) Wash out all corrosive material residues. Fill the fertilizer tanks with fresh water (if you
have some fertilizer left for next season, fill a bucket with water and place it instead of the
tank), then run the system with a program that will use all the injectors. Ensure that each
injector receives at least 20 liters (4 gallons) of water.
(2) Close all manual valves and turn all pumps switches Off. Define the Elgal controller “Not
active”.
(3) Disconnect Fertijet’s inlet and outlet pipes from the main pipe and tip over to drain of all
contents.
(4) Dismantle all records and bleed all water residues from the Venturi injectors, electrical
valves, check valves and other elements as required.
(5) In applications employing main fertilizer NC valves, make sure to dry all the 8mm
command hoses, the solenoid valve, and both the upper and lower chambers of each valve.
(6) Open the booster pump’s draining cap (Figure 9) and leave it opened for 1 hour.
(7) Verify bleeding of all pipes.
(8) Remove one of the probes from the EC-pH sampling cell and drip in 50cc (2 OZ) of
concentrated antifreeze material. Re- fit the probe in place and secure with bolt.

(9)
Clean the Fertijet of all external residues of corrosive materials. Cover the Fertijet with a
sheet. Do not shut controller’s power supply down! – leaving the Elgal controller
powered down for an extended period of time may drain the memory backup lithium
battery.
