When using acid/chemicals
ACID HAZARD
When using acid - always observe the acid manufacturer's safety instructions.
WARNING
Always use protective equipment, gloves and goggles when handling fertilizers, acid and
other chemicals!
WARNING
Exceeding the recommended acid concentrations will damage the dosing channels.
WARNING
Substances such as chemicals for pest/disease control might be corrosive and damage the
FertiKit™ 3G. When using any substance other than fertilizers or acids not exceeding the
concentrations in the table above, always observe the manufacturer's instructions for corrosivity.
In case of any doubt, contact your Netafim™ local representative.
CAUTION
There are fertilizer combinations that at high concentration might induce crystallization in the FertiKit's
lower manifold and cause clogging of the pipes.
Fertilizer combinations prone to induce crystallization:
• Calcium Nitrate + Ammonium Sulfate => Calcium Sulfate
• Calcium Nitrate + Potassium Sulfate => Calcium Sulfate
• MKP + Calcium Nitrate => Calcium Phosphate
• MAP + Calcium Nitrate => Calcium Phosphate
• Phosphoric acid + Calcium Nitrate => Calcium Phosphate
When injecting these fertilizer combinations:
• Make sure to dilute each fertilizer to the allowed concentration in the fertilizer tank prior to
injection through the FertiKit™.
• Imediately after each injection of any of the fertilizer combinations above, flush the FertiKit™ with
clean water for at least 2 minutes.
In case of doubt regarding the use of any combination of fertilizers, contact your Netafim™ local
representative.

FERTIKIT 3G INSTALLATION MANUAL 9
DESCRIPTION
Operating principle
The FertiKitTM doses the various fertilizers and acid into a homogeneous solution and injects it into the
irrigation water main line. The suction of the fertilizers and acid in the dosing channels is based on the
Venturi principle. This requires a pressure differentiation - available on the main line or supplied by the main
line pump or the FertiKit's dosing booster.
Modularity
The modular FertiKitTM 3G concept is based upon an array of interchangeable components that enables
rapid assembly of a wide range of configurations.
Each FertiKitTM is delivered according to the precise customer’s order, either fully factory assembled or
assembled by the local dealer.
The dealer stocks the assortment of the FertiKitTM interchangeable components.
This concept enables the dealer to assemble any specific FertiKitTM according to the customer’s
order, saving the need to stock a large quantity of fully assembled FertiKitTM units of various common
configurations.
The modular FertiKitTM 3G concept ensures prompt delivery schedules without delays!
Stock selection option
Enables the dosing of multiple fertilizers through a single dosing channel (in cases where simultaneous
dosing is not required). Suits all modes of FertiKitTM.Available in a wide variety of configurations, from a
single dosing channel with 2 fertilizers to as many dosing channels and fertilizers as required. For further
information, contact Netafim™.
Compatibility
The FertiKitTM 3G can be incorporated in an existing or a planned project; in either case it offers a highly
cost-effective solution for NutrigationTM by taking maximum advantage of the infrastructure conditions.
Any available pressure surplus can be used for the FertiKit’s operation. In order to configure the most
cost-effective FertiKitTM, making the maximum use of available pressure.
ATTENTION
Calculations are either in metric or in US units - consistency in the type of units used is essential.
Service
Servicing the FertiKitTM 3G is a prompt and simple process. The dealer keeps a small quantity of
interchangeable components on hand, for replacement on site within a few minutes.
Maintenance
To prevent failures and extend the life cycle of the FertiKitTM, regular maintenance must be carried out
by the user, such as periodic rinsing of filters and calibration of the EC/pH sensors. For full maintenance
instructions, see Maintenance in the User Manual (The User Manual is provided with the FertiKit™
and can be downloaded at https://www.netafim.com/en/digital-farming/netbeat/Fertigation/fertikit/).

pressure (around 0 bar/psi) this allows the use of high-efficiency
Venturis with high suction capacity and low motive flow consumption.
Since all the main line water flows through the system, slight
pressure losses at the FettiKit™ outlet should be considered
(see the table below).
