INTRODUCTION
We thank you for trusting the core of your growing success in our hands�
We in Galcon are fully aware how critical the performance and the reliability of your machine is
for your yields, and we are fully committed for supporting and serving this product�
In this manual you will nd general information on how to unpack, connect, adjust
and operate your new Fertijet machine. Fertijet machines comes with variety
of booster pumps, Dosing channels, dosing valves and even pipe dimensions�
Those components are subject for occasional changes as technology advances,
and therefor will only be described here in a general�
Fertijet can be operated either by Galileo Greenhouse app or Open-Field app,
and even by other, non-Galcon controllers. For operation please refer to the
specic applications guiding book.
Multi-channel fertigation machines are needed because some fertilizers cannot
be mixed with others�
Study your fertilizers and avoid wrong mixing� Failing it will result a quick ceramic
sedimentation in the system that is very hard to remove�
Follow the instructions hereby step by step and don’t hesitate to contact our
local representative if necessary�

SAFETY
All hazardous electric voltage jobs must be conducted by a local qualied
electrician and according to local regulations�
Do not leave the electric cabin, the motor cover or any junction box
opened while the machine at work or while you are away�
Some fertilizers and all acids are hazardous:
a� Store them in a locked place, away from reach of children and animals�
b� Always wear rubber-gloves and protecting-glasses when handling
them�
c� Never pour water or other liquids into concentrated acid!
d� Wear a full-face mask when mixing acids.
e� Mark your stock tanks clearly, stating the danger in each�
f� Install a hands-free eye washing sink within a range of 15m from
where the fertilizers are prepared�
All possible out-takes downstream the Fertijet must be
clearly marked NOR FOR DRINK�

INSTALLATION REQUIREMENTS

6Fertijet- Installation Guide and User Manual
To avoid the injection of chemicals to pipelines when not irrigating -
Verify on each installation:
A� Water meter with electric pulse is mandatory on the pipe-line that
the Fertijet is connected, before any distribution. The pulse size
must enable reading (2 pulses) in less than 1 minute�
B� Verify the validity of the water meter and its pulse daily�
C� We strongly recommend an additional pressure switch to be
connected to the controller as a delay condition element�
D� Backow preventer must always be installed upstream the Fertijet,
unless direct pumping from irrigation-dedicated lagoon.

winterization
Winter time in frost-tend area may become harmful for all irrigation components
if not well prepared�
The following steps guide you to safe winterizing� Follow them strictly�
The best time to begin winterization actions is the morning following the last
day of the irrigation Season�
Winterizing
1� Wash all remains of corrosive materials� Fill fresh water in the fertilizer tanks
(in case you have some Fertilizer left for next season, ll a bucket with water
and place it instead of the tank) and operate The system with a program
that will use all the injectors. Ensure a leach of 20 liters (4 gallons) atleast for
each injector.
2� Close all manual valves and turn o all pumps switches. Dene the Elgal
controller “not active”�
3� Disconnect the machine inlet and outlet pipes from the main pipe and tip
their content o.
4� Apart all the available records and bleed any remains of water from the
venturi injectors, electric Valves, check valves and other parts.
5� If main fertilizer nc valves exist – make sure to dry all the 8 mm command
hoses, the solenoid Valve, and both upper and lower chambers of each
valve�
6� Open the booster pump’s draining cork and leave it opened for one hour�
7� Verify draining 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� Return the probe to its place and
fasten its bolt�
9� Clean the machine of all external remains of corrosive materials� Cover the
machine with a sheet�
Do not shut down the controller’s power supply, leaving the elgal
controller powered o for long Time may cause extensive use of the memory
and shorten its life�

18 Fertijet- Installation Guide and User Manual
EC/PH Electrodes
Clean the EC/pH electrodes on a weekly basis� Thus it is recommended to
remove any impurity on the electrodes for 10 minutes with the acid solution
prepared in the acid tank�
Use 4.0 and 7.0 Buer solutions for the pH, and the 1.4 mS/cm solution for
the EC�
For the pH electrode, measure how long it takes the electrode to reach a
reading of 4�0 to 7�0� For this exercise use the pH 4�0 and 7�0 solutions; Whereas
if the time elapsed exceeds 30 seconds, the pH electrode should be replaced to
assure control�

TROUBLESHOOTING
Symptom Possible reason Sulution
The booster pump
doesn’t start when
commanded�
a� Check the main
power�
b� Check the ~24v
breaker in the Fertijet.
c� Check the ~24V fuse
in the Galileo�
d� Make sure line
pressure is above the
stated value of the
pump�
The booster pump
rotates but no suction
power�
a� Check the motor
direction� It must be
as indicated by the
arrow on the motor or
on the pump body�
b� Open the union (or
ange) at the pump
inlet and verify the
free ow of water into
the pump�
a� Change the
sequence between
2 phases (By
electrician)
Dierence between the
line pressure and the
suction pressure is less
than 25 m
Check if the venturi
blocks orice has been
deformed and replace
them if necessary�

20 Fertijet- Installation Guide and User Manual
Symptom Possible reason Sulution
The pressure gauge
between the Venturi and
the pump often indicates
-5 m or less.
Increase the line
pressure or adjust the
PSV at the pump outlet
to higher pressure�
Dosing valve doesn’t
respond to command�
Replace the dosing
valve�
Dosing valve ‘ticks’ but
no ow is detected.
a� Check the fertilizer
supply� Saturated
fertilizer sometimes
crystalizes at cold
environment�
b� Check the inner parts
of the dosing valves�
c� Check the non-
return valve and the
venturi inlet for chips
of plastic that may
escaped the tank’s
lter
a� Dissolve with water
b� Some of the valve
parts, like spring
and diaphragm are
replaceable�
