1 Features
The Wamix units are vacuum mixers used not only for mixing all kinds of plasters, embedding media and silicones, but also designed for specialised dental procedures and for vacuum-rinsing of prostheses.
When mixing silicones, make sure that the beaker is only filled to the max. height for silicone. Otherwise, silicone could penetrate the interior of the unit itself. A control window on the device makes overfilling visible (see figure 3).
Units have separate drives for vacuum generation and for the mixing mechanism. The agitator of the Wamix-Comfort IV can be turned on and off individually at all times without interrupting the vacuum. An audible signal indicates the end of the mixing process.
This is controlled by a microchip in the Wamix-Comfort IV model. Because the mixing beaker on the Wamix-Comfort IV is held to the rim by vacuum, a vacuum is guaranteed.
Mixers are supplied as wall units, but can be converted for tabletop use at any time. (For accessories, see section 8.5)
- Well-designed and compact vacuum stirrers with powerful, maintenance-free motors.

5 Application
Wamix units are used for mixing all kinds of plasters, embedding media, and silicones under vacuum.
This unit is also suitable for vacuum rinsing of models for special dental procedures. The insulating layer between the model and the prosthesis cannot separate prematurely because the model remains moister in the pressure-embedding unit than when water is used.
Only use the device for this type of application.
6 Before Starting
6.1 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.
ℹ️ Be sure to check for any transport damage when unpacking the goods. Note down any damage if found.
6.2 Installation
Open the box, remove the packing materials, and carefully lift out the device and accessories. Check the included accessories.
The device must stand horizontally on a steady and even surface or may be mounted horizontally to a stable wall using the wall bracket (included in delivery).
If mounting on a wall, ensure that the wall is strong enough to support the unit. Detach the wall mount from the unit and use it as a template for drawing a drilling scheme to drill the Ø 8 mm diameter dowel holes. Leave at least 30-35 cm free space beneath the unit. Use the following hole template (page 8) if mounting the unit on a wall:
⚠️ Install the device in a place where it will not block the working area and the functionality (take the dimensions into account).
⚠️ Do not install the unit outdoors or in places without proper ventilation. Before start-up, be sure the device reaches room temperature.
6.3 Storage
If the unit is to be stored for an extended period, protect it from moisture and dust.
6.4 Mounting Instruction Fastening Set for Wall Mounting
Please check the included accessories:
| Quantity | Name |
|---|---|
| 1 | Securing bracket |
| 1 | Phillips head screw M 4x8 |
| 1 | Washer Ø 4,3 |
| 1 | Serrated washer Ø 4,3 |
| 1 | Slotted screw 4 x 16 |
| 2 | Slotted screw 6 x 50 |
| 2 | Screw anchor S8 |
| 1 | Screw anchor S5 |
Mounting Instruction: Please drill the holes as indicated in the following drilling template. Please make sure before that the wall is really suitable for mounting a device (aerated concrete walls and drywall are problematic).
Drilling Template:
Bohrung=drilling, tief=deep
[Diagram Description: A diagram shows a wall template with dimensions. Two holes are marked for 8 mm diameter, 55 mm deep drilling, spaced 140 mm apart horizontally and 150 mm apart vertically. Below these, a single hole is marked for 5 mm diameter, 30 mm deep drilling, 34 mm from the left edge.]
Secure the enclosed screw anchors as shown in Figure 1. Screw the 6x50 screws into the two upper holes; keep a distance of 6-7 mm to the wall! (Figure 2)
[Diagram Description: Figure 1 shows three screw anchors being inserted into a wall. Figure 2 illustrates a side view of a screw being inserted into a wall, showing an 8 mm to 9 mm gap.]
Screw the securing bracket to the Wamix as shown in Figure 3. Do not yet fully tighten the Phillips head screw, however – you still need to be able to move the securing bracket.
[Diagram Description: Figure 3 shows the underside of the Wamix unit with the securing bracket being attached. Labels indicate 'Washer', 'Serrated washer', 'Phillips head screw', 'Securing angle', 'Screw 4x16', and 'control window'.]
Carefully hook in the device. Check whether the device hangs loosely (i.e., moving back and forth on the screws). If this is the case, tighten the 6x50 screws until the device hangs securely. Finally, tighten the securing bracket. First at the wall, then tighten the screw on the device itself (Figure 3).
7 Installation / Start-up
ℹ️ Before starting the unit, connect up the following: Insert the power plug into the socket, making sure that the mains and the unit operate on the same voltage.
Start-up: Turn on the green switch (see (4) fig. 4).
ℹ️ Accidental mixing is not possible because the motor cannot start until the beaker is held to the rim by the vacuum. The mixing time also needs to be set.
⚠️ Before you start your vacuum mixer, make sure that the safety hook has been fastened under the unit. Push the hook to the wall using the slot and fasten the safety hook to the wall. Then retighten the screw on the chassis to prevent it coming loose.
⚠️ Warning: Use only beakers with the new curved seal (171708).
ℹ️ When using the 115 V version, you have to install the power pack Order no. 171976. Therefore, plug in the conductor of the Wamix into the socket (Pos.1) of the power pack. The conductor of the power pack (Pos.2) has to be plugged into the house socket. In order to mount the power pack at the table stand, please use the enclosed screws M6.
[Diagram Description: A diagram shows the rear of the unit with two connection points labeled 'Pos. 1' and 'Pos. 2', indicating where the power pack connects.]
ℹ️ Switch the vacuum mixer off if the unit will not be used for an extended period.
8 Operation
8.1 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.
ℹ️ Do not fill the beaker higher than to the Max marking. Too much added material otherwise is taken up by the vacuum into the system. In the "control window" (Figure 3) the absorbed material is visible. An early switching off the unit reduces the cost of repairs!
ℹ️ The beaker will come away automatically once the vacuum is removed. To avoid damaging the seal, never remove the beaker by force.
ℹ️ The sealing surfaces between the beaker and the plate must be clean, likewise the rotor fastenings and the beaker lid, to ensure trouble-free operation.
8.1.1 Speed Adjustment
This unit is equipped with a speed regulation of the agitator from 200 – 600 rpm.
A: Automatic Agitator-Boost Connection: Adjusting knob (1) is between 200 min⁻¹ - 600 min⁻¹ individually adjustable. The agitator starts automatically and immediately when vacuum is sufficient (fig. 4).
B: Manual Agitator-Boost Connection: Adjusting knob (1) position "0". After the vacuum was built, set the adjusting knob (1) between 200 min⁻¹ - 600 min⁻¹ (fig. 4).
ℹ️ Please do not use the speed "0" longer than 240 sec.!

10 Care and Maintenance
10.1 Cleaning
⚠️ Disconnect the power plug before starting any maintenance work. The identification plate has always to be kept in easily legible condition and has not to be removed.
ℹ️ Remove external dirt from time to time with some form of cold cleaner. Use only cold cleaners to avoid damaging the paintwork or removing the lettering.
The equipment should be cleaned at regular intervals to ensure trouble-free operation. It requires only normal cleaning (sponge, damp cloth, mild detergent) and no further chemical additives.
Solvents must not be used to clean the front panel!
Keep the beaker clean. When not in use, fill with water to just below the mixer.
ℹ️ Cleaning mixing beakers in an ultrasonic bath, especially if plaster solvents are also used in the beaker, will inevitably result in changes to the structure of the beaker material and will therefore damage the mixing beaker.
10.2 Maintenance
ℹ️ Allow the condensers to discharge before you open the mixer.
Our vacuum mixers do not require servicing. Make sure the unit is kept clean and that the rim seal for the beaker (vacuum seal) is not damaged.
10.2.1 Changing the Filter
[Diagram Description: An image shows the underside of the Wamix unit, highlighting the mixer mechanism and rim. A screw labeled '1' is indicated near the filter area.]
Remove screw (1) (on the left, near the mixer mechanism on the rim under the unit). The filter swings loose at the forward end of the screw. After changing the filter, do up the screw finger-tight (do not forget the O-ring).
10.3 Warranty
ℹ️ The warranty period for our equipment is 12 months. If faults occur within the warranty period, contact your dental depot or get in touch directly with our service department.
Your equipment should only be operated in perfect condition. If faults occur which could harm operators or third parties, the unit should not be used until it has been fixed.
