Scope of Delivery:
230 V dosing pump, stainless steel suction lance with foot filter and
2.5 m suction + 2.5 m return hose, 5 m pressure hose, electric
connection, nozzle kits, weld-on tubes (for fastening the nozzles on
the screw conveyor).
Standard 400 E (0.18 KW) 2 nozzle holders with nozzle kits
Standard 600 E (0.37 KW) 3 nozzle holders with nozzle kits
Standard 950 E (0.37 KW) 4 nozzle holders with nozzle kits
Quick Guide:
The following steps must be carried out prior to the first start-up of the
dosing device:
1. Screw together the suction lance. If required, seal the thread
nipple with sealing tape.
2. Unscrew the foot filter and fill the suction line with liquid. Replace
the foot filter. This is a one-time process required exclusively for
first commissioning.
3. Fully open the control valve (6) by turning it counter-clockwise.
4. Use the black button on the switch housing to switch on the pump.
5. Use the red (emergency stop) switch to switch off the pump. To
restart the pump, turn the red (emergency stop) switch clockwise.
Important! The pump must not run dry for more than 1 minute.
After a short time, the floater in the flow indicator will start to float. The
scale shows the flow rate in l/h. In order to adjust the flow rate, turn the
control valve (clockwise = reduction; counter-clockwise = increase).
In order to check the flow rate, it is necessary to measure the pump
volume in litres. This is done by placing the nozzles into a bucket and
running the pump with the desired preservative. Leave the pump
running for one minute. Measure the quantity and compare it with the
pump setting, which may be readjusted if required.

The viscosity of some preservatives depends on the temperature.
They become more viscous at cold temperatures and less
viscous at hot temperatures, which is why it is necessary to
measure the pump volume in litres.
Use the provided weld-on tubes to fix the nozzles on the screw conveyor.
The provided tension springs are pulled around the screw conveyor tube
and hooked in on the other side.
The dosing device must be rinsed with water from time to time. The
same applies when the device has not been used for several days. At
the beginning of the frost season, the device must be topped up with
antifreeze.
Wear acid-resistant gloves, safety glasses and a respiratory mask
during all work. Your safety is of paramount importance. When
working with preservatives, always have a bucket of clear water
within reach. In the event of an accident, you will thus be able to
rinse the affected body parts immediately.
It is imperative to read the safety data sheets of the respective
preservatives and to observe the manufacturer's instructions!

Important Instructions Regarding the Handling of
Preservatives
Preservatives are mixtures of strong organic acids which, in their diluted
form, have a caustic effect on the skin and mucous membranes. When
handling the product, it is therefore required to follow the precautions
commonly applicable to acids. It is imperative to wear protective
glasses, protective gloves and respiratory masks. If preservatives come
into contact with the skin, the affected area must be immediately rinsed
with plenty of water.
When grain is treated in closed rooms and/or poured into reservoirs and
silos or onto threshing floors, the acid smell may cause a nuisance to the
personnel working there. Good ventilation of the storage rooms should
therefore be ensured during this time. If possible, consider the wind
direction when selecting a set-up location for the dosing device. The
unpleasant smell will disappear a few minutes after the dosing process
and/or grain storage.
Caution! It is imperative to observe the safety data sheets and dosing
tables provided by the respective preservative manufacturers
and/or suppliers.
Storage instructions and information on how to behave in
emergencies are to be found in the DIN safety data sheets
which have to be provided by each acid manufacturer and/or
supplier.

OPERATING INSTRUCTIONS
1. What work steps are to be performed?
-Integration of the dosing device into the work process
-Mounting of the nozzle holders on the mixing screw
-Power supply of the device
-Measurement of the grain moisture
-Determination of the required acid quantity (in kg/100 kg of grain)
-Determination of the grain screw's conveying capacity (in t/h)
-Determination of the acid quantity to be injected (in kg/h)
-Selection of the nozzle size and the pressure
-Adjustment of the required pump pressure
-Functionality and tightness checks
-Connection of the dosing device to the acid tank
-Activation of the equipment combination and monitoring during
operation
2. Integration of the dosing device into the work
process
The device can be integrated into all common work processes in the
area of feed grain storage (conveyor screw or trough conveyor). The
dosing device uses at least 2 dosing nozzles (or 3 nozzles in case of
grain maize) to add the preservative at the respective starting points of
conveyor screws with a minimum length of 3 m.
From a conveying capacity of 50 t/h, it is necessary to use 3 nozzles (or
4 nozzles in case of grain maize) for the preservation of grain maize or
grain.
It is imperative to add the preservative via a screw conveyor.
After that, the grain may be transported with any means of conveyance
(conveyor belt, elevator, blower).

3. Mounting of the nozzle holders on the screw
conveyor tube
The nozzle holders must be attached to the lower end of the screw
downstream of the grain inlet. The drill hole must have a diameter of
approx. 16 mm. The nozzle holders should be placed at a distance of
1.5 times the spiral coil of the screw (approx. 20 cm).

5. Maintenance and Care
Good maintenance of the device is indispensable due to the
corrosiveness of acids. After each use, but especially before any long-
term dosing interruptions, it is imperative to thoroughly rinse the entire
line system with water. The nozzle must be removed for that purpose.
Three buckets are required for the rinsing process: one bucket of clean
water for the suction pipe and one bucket each for the return pipe and
the nozzle hoses.
Caution! At the end of the season, after completion of this
cleaning process, the line system must additionally be
rinsed with antifreeze (Caution! Frost risk!).
Shortly before switching off the device, the suction pipe should be pulled
up so that most of the liquid will be sprayed out. After that, switch off the
device.
Important
Before the new season starts, the line system must of course be
thoroughly rinsed and checked for tightness. Apart from that, it is
required to check all hose connections and their fittings.
