USE OF SYMBOLS The symbols used in this manual refer to the following: WARNING Contains instructions aimed at preventing bodily injury or direct damage to the crops, the NetaJet™ 4G and/or the infrastructure. CAUTION Contains instructions aimed at preventing unwanted system operation, installation or conditions that, if not followed, might void the warranty.
INTRODUCTION CAUTION Read the safety instructions section before beginning installation of the NetaJet™ 4G dosing unit. General instructions • Installation must be performed by authorized technicians only. • Refer to your supervisor if problems occur during the installation procedure. • Installation should be performed on a hard, leveled floor or on a flat, hard, leveled plate.
Immediately after each injection of any of the fertilizer combinations above, flush the NetaJet™ 4G with clean water for at least 2 minutes. In case of doubt regarding the use of any combination of fertilizers, contact your local Netafim™ representative.
DESCRIPTION Features • The NetaJet™ 4G realizes Netafim’s “grow more with less” concept. Based on Netafim’s unique Nutrigation™ technology, it controls the amount of water and fertilizers used, optimizing resource utilization for each specific crop and soil/substrate type. • The NetaJet™ 4G is extremely accurate and reliable, preventing water and fertilizer waste while reducing environmental pollution.
DESCRIPTION Analog dosing channel The NetaJet™ 4G is the first fertilizer-dosing system equipped with Netafim's unique innovative analog dosing channel. The analog dosing channel is the long-awaited solution for very accurate and reliable EC/pH control for Nutrigation™ of high-value greenhouse crops.
• High pressure: 5.8 - 7.5 bar (84.0 - 108.5 PSI) For main line pressures lower than 2.5 bar (36.5 PSI), consult Netafim™. NetaJet™ 4G modes fed by a storage tank The water level in the storage tank should not be higher than 5 meters (16.4 feet) above the NetaJet™ 4G inlet.

ON-SITE PREPARATIONS Infrastructure requirements In order to enable the operation of the NetaJet™ 4G it is essential to meet the specific requirements for each mode such as main line pressure and infrastructure conditions. See the relevant mode description (pages 14-24). NOTE To ensure flow rate stability, the consumption of the different irrigation shifts should be as equal as possible.
ON-SITE PREPARATIONS The fertilizer/acid tanks and lines For the setup of the fertilizer/acid tanks and lines, the following components should be installed: Items of the fertilizer/acid tanks and lines Component Specifications Fertilizer/acid stock tank Between 1 and 6 fertilizer/acid solution stock tanks Manual valve (fertilizer) A manual ball valve on each fertilizer/acid line at the stock tank outlet Fertilizer/acid filter...

INSTALLATION Unpacking and placement Check the ShockWatch label attached to the packaging and ensure the indicator is white. If the indicator is red - follow the instructions on the ShockWatch label. Using forklift, place the NetaJet™ 4G package close to the irrigation system. Carefully open the packaging.
INSTALLATION Before connecting the flexi-tube, thread a stainless steel band clamp on each flexi-tube hose. Heat the tip of each flexi-tube hose in boiling water to make it flexible for insertion. Connect the flexi-tube hose from the fertilizer lines to the hose-nozzle-insert connectors of the dosing channels ensuring 1⁄2 meter (1.7 feet) of transparent, chemical- resistant, reinforced PVC water hose with an internal...

SYSTEM OPERATION Calibration of EC and pH sensors Calibrate the EC and pH sensors (see the enclosed EC/pH Transducer Manual). CAUTION Do not operate the NetaJet™ 4G if the manual isolation valves installed at the inlet and outlet of the system are closed! ATTENTION Unions tend to get loose during transit.

(see the enclosed Controller Manual) If there is any problem during the process, see Troubleshooting in the NetaJet™ 4G User Manual provided with the NetaJet™ 4G and downloadable at https://www.netafim.com/en/digital-farming/netbeat/Fertigation/netajet/ 34 NETAJET 4G INSTALLATION MANUAL...
DOSING CALIBRATION The process of calibrating the NetaJet™ 4G dosing channels is carried out in three stages: 1. Calculation of dosing channel opening percentage To finely calibrate the NetaJet™ 4G dosing channels in order to achieve homogeneous and stable dosing, perform the following calculation for each dosing channel (fertilizers and acids) to determine the amount of suction reduction needed to attain the required fertilizer/acid flow rate.
Page 36
DOSING CALIBRATION Note the required dosing ratio of each fertilizer solution and the dosing ratio of the acid solution (if used). Fill a bucket with 10 liters (2 US gallons) of the client's supply water (without fertilizer or acid). Measure the EC and the pH levels of the water in the bucket using calibrated portable sensors. EXAMPLE Supply water (without fertilizer or acid) 0.3 Using a measuring tube or a syringe, take a dose from each fertilizer solution and from the acid solution (if...
DOSING CALIBRATION With the controller set to operate according to EC/pH values - if the EC and pH values measured in the bucket are within a range of ±30% deviation from the target values, the system will be able to correct them automatically.

After completing the calibration process, fill in the NetaJet™ 4G Hydraulic Conditions Checklist (User Manual, page 45) in three copies. Make sure to fill in all the boxes in the reference row. The NetaJet™ 4G User Manual is provided with the NetaJet™ 4G and downloadable at https://www.netafim.com/en/digital-farming/netbeat/Fertigation/netajet/ 38 NETAJET 4G INSTALLATION MANUAL...
The calibration process involves checking the pressure at several points on the NetaJet™ 4G and readjusting the system pressure regime. Contact your local Netafim™ representative for guidance. Each mode has between 2 to 3 points to attend to. At each point there is a pressure gauge and a valve (PSV or PRV) to adjust.

After completing the calibration process, the NetaJet™ 4G is ready for commissioning. Familiarize the client with the NetaJet™ 4G, the user manual (provided with the NetaJet™ 4G and downloadable at https://www.netafim.com/en/digital-farming/netbeat/Fertigation/netajet/) and the accompanying documents and emphasize the following points: •...
If the installation was not reported or was reported later than 30 days from the date of installation, Netafim™ will warrant the NetaJet™ 4G for a period of 18 months from the date of production, according to its serial number.
