Functions
The flow mixer comprises a storage tank which is separate from the mixing pipe. During operation, the dry material is fed into the mixing pipe by means of the transport/dosing shaft. In the mixing pipe, the mortar is mixed after water has been added.

Setup / initial operation

Attention:
The machine must be disconnected from the mains supply before all cleaning and maintenance work as well as assembly and disassembly of, e.g., the mixing tube, mixing shaft, metering shaft, safety grille, electrical units!
Assembling the mixing tube: Tightly fasten the pipe to the funnel housing using the two clamping levers on the water inlet. Make sure that both sealing surfaces are free of incrustations and clean.
Inserting the mixing shaft: Insert the shaft through the mixing tube and insert it into the transport/metering shaft. Here, too, remove any soiling first. Do not grease the end of the mixing shaft!
Fixing the mixing shaft: The cover fastened to the mixing shaft is tightly fastened to the mixing tube by means of the two front clamping levers. Ensure a clean sealings surface here, too.

Caution:
The safety screw in the middle of the cover must remain in place even during cleaning work! Otherwise, the operating safety of the mixing shaft is insufficient during assembly and disassembly!
Connect the water supply to the mixing pipe
Install and secure the protective grid with the bag opener rail

Water connection
Use a 3/4″ water hose as the supply line. A water back pressure of at least 3.5 bar is recommended.

Note:
Bleed the water supply line before connecting!
Tip:
Before the material container is filled, test for correct function of the mixer and bleed the water supply line on the unit. Shut-off the drain tap at the bottom on the pipeline. Remove the water supply line from the mixing tube and point into a bucket. Close the metering valve on the water supply line of the unit and open it again approx. 10 turns. Press the green On switch. The shafts begin to rotate and water escapes from the water supply line. Press the red Off button: The device stops, the solenoid valve shuts off the flow of water. Reconnect the water supply line to the mixing pipe.
Fill the material hopper with material.
Place the catchment container below the mixing tube outlet.
Switch the mixer back on at the green On switch and regulate the viscosity of the escaping material at the metering valve by closing the valve.

There will be a delay before material with the set viscosity exits the material outlet due to the length of the mixing tube.

Important:
For a constant mixing result, sufficient material must always be filled into the material hopper – the metering shaft must not be visible!

• Once the desired viscosity has been set, switch off the unit using the red Off switch.

Please note:
Mix the resulting material with a hand mixer and possibly thicken it by adding dry material, it can be used for manual processing.
Now place a catchment container or the funnel of a feed pump under the outlet.

Avoid operating breaks of more than 30 minutes! Never expose the mixer to direct sunlight during operation.

Power supply
The DMS 25 PRO flow mixer must be connected to an approved site power distributor with residual current circuit breaker or to a house mains connection with a residual current circuit breaker. A 16 A fuse is required. When using the mixer with several units (e.g., plaster pump and compressor), it is advisable to connect the units to different electrical circuits Use a connecting cable of 3 x 2.5 mm².
In order to prevent voltage loss and the risk of damage as a result, using a connecting cable no longer than 50 m is recommended. Cable drums must always be unreeled completely, then distribute the cables and do not lay them on top of each other.

Safety instructions
No more than one sack of material must be placed on the machine`s safety guard.
Only remove the safety guard and mixing pipe after disconnecting the machine from the mains.
Run all hoses and cables so as to rule out stumbling hazards to the extent possible.
Place the machine on a flat and firm surface.
The machine does not have a suspension device for crane transport!

Cleaning the flow mixer
Empty the machine`s storage tank when you finish work.
Use the red Off button to switch the machine off and isolate it from the mains.
Disconnect the water connection.
Remove and clean the mixing pipe and the mixing shaft.
Clean the storage tank and the metering unit (dry if possible).
Assemble the machine again.
Keep the shaft connections clean, dry and free from grease.
