Page 10: Pl Modes (Pl/Ps/Pr/Rl)
DESCRIPTION PL modes (PL/PS/PR/RL) Operating principle: The pressure differential required to generate fertilizer suction via the Venturis is produced by a booster pump integrated in the FertiKit These modes of operation, where the lower manifold is under low pressure (around 0 bars/PSI), permits the use of high-efficiency Venturis with high suction capacity and low motive flow consumption. -
Page 11: Pb Mode
DESCRIPTION PB mode Operating principle: The pressure differential required to generate fertilizer suction via the Venturis is produced by a booster pump integrated in the FertiKit This mode of operation, where the smaller system pump is installed upstream from the Venturis, permits the use of a small booster pump, reducing the investment required and saving energy. -
Page 12: Sp Mode
DESCRIPTION SP mode Operating principle: The pressure differential required to generate fertilizer suction via the Venturis is produced by a booster pump integrated in the FertiKit This mode of operation, where the system pump is installed upstream from the Venturis, permits the use of a smaller booster pump, reducing the investment required and saving energy. -
Page 13: Ms Mode (Ms/Rs)
DESCRIPTION MS mode (MS/RS) Operating principle: For systems operating under negative suction - from a reservoir or a tank [max. height: 6 meters (20 feet)] Utilizes the main line pump pressure. Saves the need for a dosing booster. Flow rate: 20 - 700 m³/h (85 - 3000 GPM) Suitable for main line pressure: Upstream from the pump: -0.3 - +0.6 bar (-4 - +9 PSI) At the outlet of the pump: 2.5 - 6.5 bars (36 - 94 PSI) -
Page 14: Il Mode
DESCRIPTION IL mode Operating principle: The pressure differential required to generate fertilizer suction via the Venturis is produced by a booster pump integrated in the FertiKit In this mode of operation, the lower manifold is at low pressure (around 0 bar/psi) this allows the use of high-efficiency Venturis with high suction capacity and low motive flow consumption. -
Page 15: St Mode
DESCRIPTION ST mode Operating principle: For systems operating at low pressure - from an on-ground reservoir or a tank [max. height: 6 meters (20 feet)] The dosing booster pump also serves as main line pump. Supplied with a manual or a semi-automatic filter. Flow rate: 1 - 16 m³/h (4.4 - 70 GPM) Suitable for main line pressure: Upstream from the pump: -0.3 - +0.6 bar (-4 - +9 PSI) -
Page 16: Pd Mode
Saves the need for a dosing booster. Also suitable for applications where there is no electricity on the site (contact Netafim™). Flow rate: 10 - 200 m³/h (44 - 880 GPM) Suitable for main line pressure: 4.5 - 8.0 Bars (65 - 116 PSI) -

Page 25: Appendix 1 - Calibration
APPENDIX 1 - CALIBRATION The process of calibrating the FertiKit is carried out in three stages: 1. Calculation of dosing channels opening percentage To finely calibrate the FertiKit in order to achieve homogeneous and stable dosing, perform the following calculation for each dosing channel (fertilizers and acid) to determine the amount of suction reduction needed to attain the required fertilizer/acid flow rate. - Page 26 APPENDIX 1 - 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.

Page 27: Tm While Irrigating
APPENDIX 1 - 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 28 APPENDIX 1 - 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.
