Features

Mixing and dosing of addition-vulcanizing 1:1 two-component silicones. For even dosage of both components, both must have similar viscosity. The additional quantity flow control ensures an optimum mixing ratio. Should there be discrepancies, for example, for technical reasons (wear of the pump), or following a change of components with different viscosity, the mixing ratio can be adjusted.

Advantages:

• Mixing head with separate output openings – mixing of A and B components while mounting or dismounting the mixing cannula is impossible
• Automatic production of homogeneous silicone material without any loss or bubbles at the press of a button
• Saves material and time by filling more than one bowl at the same time with just a single mixing cannula
• Forced mixing by a disposable mixing cannula, pink with a bayonet mount
• Containers with quick couplings mounted directly on the device
• With quick coupling for mounting of 1 kg and 6 kg or 25 kg
• 1 kg: adapter set available, pad stand not required, connection hoses not required
• 6 kg: adapter set available, optional small pad stand available, (usage with pad stand: connection hoses required)
• 25 kg: tall pad stand required, adapter set with connection hoses required
• The included 2×2 liter material containers feature a quick coupling and can be used immediately.

Safety Guidelines

Configuring and operating this equipment requires precise knowledge and observance of the instructions in this user manual. The equipment is designed only for its intended application.

WARNING:
Servicing and repairs should be carried out only by authorized specialists. Disconnect the power plug before starting any maintenance work.
Make sure that the equipment is connected to the correct power source.
Always keep the two silicone components separated – never mix up the connections! The mixing of components would cause the silicone within the device to harden, making extensive repairs to the device in the Hamburg plant necessary.
Drill a ventilation hole using a drill or similar tool at the upper side edge of the 1-liter bottle or 6 kg or 25 kg can. Do not tighten the caps of the 2-litre material containers, but just fit them loosely to ensure proper ventilation.
After hardening and before further usage, fit a new mixing cannula.

WARNING: Never use a hardened mixing cannula!
Note that while using bulk containers, the cans must be positioned at a height higher than the device. Optional pad stands are available on request.
Leave about 2-3 cm minimal filling inside the containers to avoid air getting into the system and the need for demanding to bleed of the device.

WARNING: It is very important to pay attention to this minimal filling! The pump must never be used without material (never “running dry”)!

Before Starting

Transport
Before transporting the unit, ensure that it has been unplugged from the power socket. Make sure that it is packed correctly in order to avoid accidental damage. Be sure to check for any transport damage when unpacking the goods. Note down any damage if found.

Installation

Open the box, remove the packing materials, and carefully lift out the device and accessories. Check the included accessories.
The device has to stand horizontally on a steady and even surface.

Install the device in a place where it will not block the working area and the functionality (take the dimensions into account). Make sure that there are about 10 cm of free space on each side to guarantee air circulation (heat dissipation).

Do not install the unit outdoors or in places without proper ventilation.
Before start-up, be sure the device reaches room temperature.

Storage
The unit location is very important when it comes to workplace safety, even if it is only to be set up there for a short period. The room should be dry, well ventilated, and vibration-free. An even temperature and wooden supports also help. The unit should not be stored or set up outdoors. If the unit is to be stored for an extended period, protect it from moisture and dust.

Installation/ Start-up

Before starting the unit, connect up the following:

• Remove the closing plugs from the connections and dosage head.
• Finally, insert the power plug into the socket, making sure that the mains and the unit operate on the same voltage.

When using 2 Litre Material Containers (included):

Fill the material container with the relevant component.
Warning: Insert the container filled with colored silicone compound – component B – into the color-marked entry at the back of the device. Do not mix up! If you mix up the closings even for a short time, the device must be disassembled and cleaned.

Very important: Do not tighten the caps of the material containers, but just fit them loosely to ensure proper ventilation.

When using 1 kg Bottles:

Remove the closings of the bottles filled with two-component silicone and screw the above-mentioned metal quick closings (accessories) onto the bottles.
Warning: Screw the color-marked quick closings onto the bottles filled with colored silicone compound – component B. Do not mix up! If you mix up the closings even for a short time, the device must be disassembled and cleaned. Insert the bottles with quick closings into the entry on the back of the device (the bottles will be upside down).

Very important: Drill a ventilation hole using a drill or similar tool at the upper side edge of the bottles to ensure proper ventilation.

When using 6 kg Bulks:
Remove the closings from the cans filled with two-component silicone and screw the adaptor set onto the cans.
Warning: Screw the color-marked adapter onto the can filled with colored silicone compound – component B. Do not mix up! If you mix up the closings even for a short time, the device must be disassembled and cleaned.
Insert the can with quick closings into the entry on the back of the device (the can will be upside down).

Very important: Drill a ventilation hole using a drill or similar tool at the upper side edge of the can to ensure proper ventilation.

When using 25 kg Bulks:

Note that while using bulk containers, the cans must be positioned at a height higher than the device. Optional pad stands are available on request.
Remove the closings from the cans filled with two-component silicone and screw connection hoses onto the cans.
Warning: Screw the color-marked connection hose onto the can filled with colored silicone compound – Component B – screw on. Do not mix up! If you mix up the closings even for a short time, the device must be disassembled and cleaned.
Place the can, e.g. on the optional pad stand, to make sure that it will be placed higher than the dosage device (can be upside down), and insert the connection hoses with quick closings into the entry on the back of the device.

Very important: Drill a ventilation hole using a drill or similar tool at the upper side edge of the can to ensure proper ventilation.

Replacing Bottles/ Cans:
Remove the quick coupling/bottle adaptor from the device by pulling up the lock. Screw the quick coupling/bottle adaptor onto the new bottle/can and connect as explained above.

Take special care to never confuse the bottles or connection hoses A+B – not even for a short time – since the silicone within the connections and pipes hardens instantly! The cleaning procedure is very demanding and may only be performed by authorized repair companies.
Note that while using bulk containers, the cans must be positioned at a height higher than the device. Optional pad stands are available on request.

Operation

General Operating Instructions
All instructions for using the unit, whether in verbal or written form, are based on our own experience and experimentation and can only be regarded as guidelines.
Switch on the device; the toggle switch lights green (right side of the unit).

Note for the Quantity Flow Control/ Setting of Quantity Flow Controller
The adjusting screws are located on the side panel of the machine. (Behind the both-sided bores of the hood, please use a screwdriver.)

• Controller closed = rotary knob is turned down quite right until it stops.
  100% of the component flows from the reservoir to the mixing tip

• Controller open = control range: from 2 to max. 4 turns to the left.
  A part of the component flows from the container to the mixing tip and a remaining part of the component flows in the bypass circuit.

• Controller open = About 4 turns to the left. 100% of the component flows in the bypass circuit so that no material flows to the mixing tip.

Initial Start-up and Material Change
The unit will be delivered with a testing liquid filled in!
Observe at the first start-up * or at material change necessarily the following,
because otherwise, this will cause a mixing of the test liquid and the material or of “old” and “new” material:
(Please pay attention to sections 3 and Sections 7.1 – 7.5! )

One-time procedure to clean up the hoses and the dosing pump:
Place an empty bowl under the mixing head without a mixing tip. The quantity flow controllers are located behind the both-sided bores of the hood. Turn both quantity flow controllers 2 ½ to 3 to the left from the closed position (stop far right) to the open position by using a screwdriver.

Now press the red button and hold it down until both components run out of the openings simultaneously and without air bubbles.
Afterward, close the quantity flow controller and check the mixing ratio. If it is not 1:1, there is the possibility to reduce the quantity flow of the component that is delivered too much. Therefore open the quantity flow controller of that component in small steps (from 2 turns to the left in 1/8-turns) in order to optimize the mixing ratio. After each adjustment, are- inspection is necessary.

Using the Mixing Tips and Dosage
Mount the mixing cannula by turning it 90° on the mixing cannula adaptor (clean the adaptor before if necessary). Place the bowl or the model to be used for doubling the system under the mixing cannula. Press the red button: 1:1 mixed silicone runs out of the mixing cannula.

We recommend collecting a small amount of the mixture initially output and just letting the substance output subsequently run into the form. You can fill more forms without changing the mixing cannula as long as the period between the single dosage operations lies within the dripping time of the used silicone (about 4 min.). The dosage machine 1:1 dispenses mixed silicone as long as you press the red button.

After use, leave the mixing cannula attached to the device and allow the remaining silicone to vulcanize. This closes the openings of both components sufficiently.

A new mixing cannula has to be fitted after hardening and before further usage.

WARNING: Never use a hardened mixing cannula!

Very important:
Do not continue operation if one or both containers are empty; otherwise the pipes will convey air (observe the minimum liquid level of the containers: ~ 2-3 cm!).

Troubleshooting

mixing cannula.
No silicone output.| Mixing head clogged.| Clean mixing head carefully.

Warning: Silicone components must not get in contact with each other!

No silicone output.| A and B component was mixed up; silicone within the device system has hardened.| The device needs to be disassembled and cleaned by a qualified technician.
No silicone output.| Minimum liquid level of the silicone containers was reached; system has sucked in air.| Add silicone compound. Position a container under the mixing head without the mixing cannula, press the red button and hold it until both components run out even and without bubbles from the mixing cannula adaptors.

Clean the mixing head and connect a new mixing cannula if necessary.

Silicone output without 1:1 ratio.| Silicone components do not have similar viscosity.| We recommend using Wassermann doubling silicones WaSil soft and WaSil speed.
Silicone output without 1:1 ratio.| Gears within the pump are not evenly worn.| With light wear, please see 8.2 notes to the setting of the quantity flow controller. Should this not suffice, the device needs to be inspected by a qualified technician.
