Filling the spray liquid tank and flushing water tank through the suction connection

WARNING
Health hazard due to contact with contaminated flushing water
To prevent contamination of the flushing water tank with crop protection product, the following procedure must be followed while filling:

To clean the liquid circuit:

First fill the spray liquid tank with 500l of water.
Switch off the agitator before filling the flushing water tank.
Fill the flushing water tank with water up to the target fill level. Do not stop the filling procedure prematurely.
Then fill the spray liquid tank up to the target fill level. At the same time, flush in the spray agent.
NOTE
Depending on the season and marking on the machine, the machine can be delivered with a biodegradable antifreeze in the spray liquid tank. The antifreeze can either be sprayed out at first deployment with the spray liquid or it can be pumped out before filling the tank.
Antifreeze that was emptied out can be reused or disposed of properly.

  1. If the water hardness is higher than 15° dH (German water hardness):

    Add polyphosphate-based hardness stabilisers.
  1. Take both parts 1 of the suction hose out of the parking position.
  1. Couple the two parts of the suction hose together.
  2. Take the suction strainer out of the front storage compartment and install it on the suction hose.
  3. Place the end of the suction hose with the suction strainer in the withdrawal point.
  1. Open the cover 1 of the control panel.
  1. Take off the sealing cap 1.
  2. Couple the suction hose on the suction connection 2.
  1. Select on the pressure valve chest DA.
  1. Run the spray liquid pump on the TwinTerminal.
  2. Select .
  3. Enter the target fill level for the spray liquid tank and the flushing water tank.

  1. To increase the filling capacity by activating the additional injector:

    To do so, set switch tap IJ to a position between 0 and .

To avoid contamination of the flushing water tank, the spray liquid tank must be filled with 500l of water before the flushing water tank can be filled.

  1. When the fill level of the spray liquid tank has reached 500l:

    Switch off the agitator on the TwinTerminal.
  2. Select on the pressure valve chest DA.

The flushing water tank will be filled.

  1. When the flushing water tank is filled:

    Select on the pressure valve chest DA.
  2. Switch on the agitator on the TwinTerminal.

Filling of the spray liquid tank will be resumed.

  1. If spray agent will be added:

    Flush in the spray agent during the filling procedure, Flushing in spray agent

or

Suction-extract the spray agent from a container during the filling procedure, Suction-extraction of spray agent from containers.

  1. If the pH value of the finished spray liquid is higher than 7:

    Add citric acid or a special acidifing agent.

  1. To take a filling pause for flushing in the spray agent:

    Pull the lever for pressure valve chest DA forward.

  2. To stop the filling pause:

    Press the lever to the position.

If the injector was additionally switched on to increase the filling capacity, it must be switched off before the target fill level is reached. Otherwise, the filling via the injector will not be taken into account by the automatic fill stop and the target fill level will be exceeded.

  1. Set switch tap IJ to position 0.

Filling is automatically stopped when the target fill level has been reached. The suction hose is still filled with water.

  1. Uncouple the suction hose from the suction connection

or

To drain the suction hose through the suction strainer:

With the lever 1 on the suction strainer, open the non-return valve and drain out the water remaining in the suction hose. Then uncouple the suction hose from the suction connection.
  1. Fit the sealing cap on the suction connection.
  2. Select on the pressure valve chest DA.
  3. Close the cover of the control panel.
  4. Disconnect the two parts of the suction hose and the suction strainer.
  5. Fasten both parts of the suction hose in the parking position on the right and left mudguard.
  6. Clean the suction strainer, dry it and stow it in the front storage compartment.
