  • Page 4: Safety

    SAFETY CAUTION Read the safety instructions before using, maintaining or troubleshooting the NetaJet™ 4G. Safety instructions • All safety regulations must be applied. • Ensure that the installation is carried out in a manner that prevents leaks from the NetaJet™ 4G, the fertilizer/acid tanks and lines, the peripherals and the accessories (contaminating the environment, soil or ambient area).

  • Page 5: When Using Acid/Chemicals

    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.

  • Page 6: Description

    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.

  • Page 30: Dosing Calibration

    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 31 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...

  • Page 32: Calibration Of The Netajet™ 4G While Irrigating

    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.
  • Page 33 DOSING CALIBRATION If the EC and pH target values cannot be attained, and the dosing valves are opened more than 85%, measures should be taken to increase the dosing ratio - if feasible, slightly increase the concentration of the fertilizer solution and/or reduce the water flow rate to the field during irrigation. If not - consult the agronomist/consultant.
