  • Page 9: Electrical Safety

    The unit is powered from the mains voltage. There is a potential hazard of electrocution or fire resulting from a short circuit. You must therefore adhere to the following safety instructions: • Keep the housings of electrical components closed. • Keep the electrical parts dry. NutriJet - user - 00.002...

  • Page 10: Safety With Mechanical Parts

    The fan of the electric motor on the system pump is protected by a cover. • The motor protection switches the system pump off if it is consuming too much current due to overloading. The process computer detects this situation and then shuts down the entire unit. NutriJet - user - 00.002...

  • Page 11: Residual Risks

    Because the unit is usually connected to other external electrical equipment the unit has not been fitted with an emergency stop. The installer must install a separate emergency button near the unit which can be used to switch off the entire installation. NutriJet - user - 00.002...

  • Page 12: Product Description

    The pressure and capacity of the irrigation water supplied by the unit are dependent on the pump on the unit. Optionally, you can choose to regulate the pressure of the irrigation water with a frequency controller. NutriJet - user - 00.002...

  • Page 18: Operating Principle

    • NutriJet Bypass: the unit is installed next to the main line. Part of the water is guided out of the main line, via the unit, back to the main line. The unit delivers such a high dosage that the correct dosage is achieved after mixing in the main line.
  • Page 19 The rinse water is discharged via the drain line (42). If not already present on the unit, a non-return valve (43) must be installed behind the filter. If non-return valve (43) is present on the unit, non-return valve (13) is not required. NutriJet - user - 00.002...

  • Page 20: Nutrijet Bypass

    (4) and the outlet line (14) must be equipped with a manually operated valve (5). The operation of other components of the NutriJet Bypass and those of the NutriJet Inline are the same. A frequency controller, EC pre-control or post-filtration cannot be used with the NutriJet Bypass.

  • Page 21: Transport And Storage

    Transport and storage Transport and storage Only Priva approved installers/service engineers who have received product-specific training from Priva are allowed to transport and store the unit. The work to be performed by the installer for transport and storage is described in the unit’s installer manual.

  • Page 26 If you use supply water with an EC value that is too high it is possible that no fertilisers or a very small quantity of fertilisers will be dosed. NutriJet - user - 00.002...

  • Page 27: Maintenance And Repair

    • Some maintenance activities may only be performed by authorised Priva installers/service engineers who have received product-specific training from Priva. This is indicated in the preventative maintenance schedule. • Switch the unit off using the main disconnect switch before carrying out any maintenance work.

    During the production of irrigation water, the pressure on the line to the venturis is too low (page 33) NutriJet Bypass: The suction pressure on the line after the mixing chamber is too low or too high (page 33) A fertiliser, acid or lye is not being dosed (page 33) The desired EC value is not being achieved (page 34) The EC value swings wildly and ‘overshoots’...
  • Page 34 NutriJet Bypass: EC control is unstable (page 32) NutriJet Bypass: The pressure on the pressure reducing valves in the incoming line is too The first manometer on the pressure reducing valves in the incoming line indicates too low a pressure.
  • Page 35 Clean the dirt filter (see Cleaning the inline dirt filter (page 27)). NutriJet Bypass: The suction pressure on the line after the mixing chamber is too low or too high Possible cause Solution The pressure reducing valve or valves in the bypass line Priva Partner: adjust the pressure reducing valve or have not been adjusted correctly.
  • Page 36 • Increase the concentration of the acid or lye. The supply water contains too much bicarbonate. Priva Partner: install a pre-treatment system for the supply water. The nutrient recipe has been set incorrectly. Adjust the quantity of acid or lye in the nutrient recipe, taking into account the quantity of bicarbonate in the supply water.
  • Page 37 Reduce the quantity of acid or lye in the recipe. The supply water contains too little bicarbonate. Priva Partner: install a flow rate ratio control to mix the supply water with another water source that contains the correct amount of bicarbonate.

  • Page 38: Troubleshooting - Process Computer

    Some irrigation valves no longer open Possible cause Solution A fuse of the relevant fuse group on the I/O board has Priva Partner: replace the defective fuse (see Zekeringen burned out. vervangen). The measured fertiliser concentrations do not match the recipe...

    When using reverse osmosis water, but in some cases rain water also, too low a quantity of HCO (< 0.10 mmol/l) may be deemed to exist in the supply water. Dosing acid may give rise to an unstable chemical reaction in the irrigation water. NutriJet - user - 00.002...
  • Page 43 Dosing acid may then result in there being insufficient time to neutralise the bicarbonate. Stabilisation is possible by pre-treating the supply water using a Priva Neutralizer with an acid injection and aeration system. The treated supply water is then stored in a stock tank.

  • Page 44: Preparing An Acid Supply

    To dilute this to 3% (weight percent), it is necessary to mix the contents of the barrel with 315, 470 or 640 l fresh water. Always pour the acid into the water instead of the water into the acid, and always stir the mixture thoroughly to homogenise it. Example NutriJet - user - 00.002...
