1 Features
Wamix is a manufacturer of vacuum mixers used not only for mixing all inds of plasters,
embedding media and silicones, but also designed for specialised dental procedures and
for vacuum-rinsing of prostheses.
When mixing silicones, ma e sure that the bea er is only filled to the max. hei ht for
silicone. Otherwise, silicone could penetrate the interior of the unit itself.
Units have separate drives for vacuum generation and for the mixing mechanism. The
mixer in the Wamix-Classic and -Injector IV versions can be switched on and off at any
time by pressing a button, without interruption of vacuum.
Until changed, the current preset mixing time (up to 999 sec.) becomes the default for
subsequent use. An audible signal (approx. 5 sec.) indicates the end of the mixing
process, time display flashes.
The vacuum is guaranteed because the bea er on the Wamix-Classic and -Injector IV is
held to the flange by the vacuum. Mixers are supplied as wall units, but can be converted
for tabletop use at any time. (For accessories, see 8.5)
•compact vacuum stirrers with powerful, maintenance-free motors

5 Application
Wamix equipment is used for mixing all inds of plasters, embedding media and silicones
under vacuum.
The vacuum can be as high as approx. 900 - 950 mbar.
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.

7 Start-up / Installation
Chec that the mains voltage and the voltage requirements of the mixer are the
same, then plug in the power cable.
Only for Wamix-Injector IV:
Install a compressed air line in accordance with the technical data. Be sure to use the
correct hose size if the line is long (inside diameter min. 6 mm). Provide a servicing unit for
each line and use a pressure regulator to maintain a constant pressure.
Accidental mixin is not possible because the motor cannot start until the
beaker is held to the rim by the vacuum. The mixin 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 usin the slot and
fasten the safety hook to the wall. Than reti hten the screw on the chassis
to prevent it comin loose.
Warnin : Use only beakers with the new curved seal (171708).
When usin the 115 V version you have to install the power pack Order no.
171976. Therefore you plu 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 plu ed into the house socket. In order to mount the power pack at the
table stand please use the enclosed screws M6.

Pos. 2 Pos. 1

Start-up / Installation
Switch on green master switch (1) (vacuum mixing).
Only for Wamix-Injector IV:
Open compressed air valve
When the device is used for the first time, the vacuum first needs to be adjusted at the
throttle valve (for the vacuum generator) using a screwdriver. The recommended input
pressure is a minimum 5 bar. The throttle valve (see fi . 4) is located on the front lower
right of the chassis (remove the blac cover). Slowly open the valve from its zero position
(to the left = +, to the right = -), until the needle is in the green zone. The best vacuum
will not be obtained if the valve is fully open - a middle setting is best. This should be
adjusted later if the pressure changes.
Wamix-Injector IV: If the needle does not reach the big end of the green zone on
the pressure gauge during the setting, there is too little flow to the unit. Chec the
compressed-air supply.
If the equipment will not be used for an extended period, switch off the compressed-
air supply and the vacuum mixer.
12
Remove the blac cover –
the spindle of the throttle
valve for the vacuum is
located behind it.

8 Operation
8.1 General operatin instructions
All instructions for usin the unit, whether in verbal or written form, are based
on our own experience and experimentation and can only be re arded as
uidelines.
Fill the beaker to the Max marking. The vacuum will draw any excess material
into the system.
The beaker will come away automatically once the vacuum is removed. To
avoid dama in the seal, never remove the beaker by force.
The sealin surfaces between the beaker and the plate has to be clean -
likewise the rotor fastenin s and the beaker lid - to ensure trouble-free
operation.

8.2 VACUUM MIXING with the Wamix
By default, the timer is set to 60 seconds.
6.2.1 Wamix-Classic IV
1. Set the mixing time on the timer (1) (up to 999 sec.) using the buttons (4 and 5).
A: Automatic mixin = turning nob (7) you can ma e a free choice of 200 rpm until 600
rpm. – mixing time is stored until a new time is set.
B: For manual mixin = set the turning nob (7) to “0”, and switch the mixer on once
vacuum is created, turning nob (7) to the position which you need.
Please note: The timer (total time) starts countin down as soon as sufficient
vacuum is achieved (beaker securely attached to the device). As this therefore
corresponds to the mixin time, the mixer can be switched on and off any number of
times (e. . for pre- and post-vacuum). The be innin and end of the mixin time can
be read on the timer display (6).
2. Place the mixing materials in the bea er and mix by hand until the powder is well mixed
with the liquid.
3. Seal the bea er with a lid.

5. The mixer switches on automatically (depending on the settings – see point 1) for the set
period of time. At the end of this period, an alert si nal sounds for 5 seconds, after
which the timer display (6) flashes until the main switch (2) is switched off.
6. Ta e hold of the bea er before you switch off the master switch (1) (vacuum).
After the vacuum in the bea er drops, the bea er will no longer be clamped to the unit.
6.2.2 Wamix-Injector IV
1. Set the mixing time on the timer (1) (up to 999 sec.) using the buttons (4 and 5).

10 Care and maintenance
10.1 Cleanin
Disconnect the power plug before starting any maintenance wor .
The identification plate has always to be ept in easily legible condition and has
not to be removed.
Remove external dirt from time to time with some form of cold cleaner.
Use only cold cleaners to avoid damaging the paintwor 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 bea er clean. When not in use, fill with water to just below the mixer.
Cleaning mixing bea ers in an ultrasonic bath, especially if plaster solvents are
also used in the bea er, will inevitably result in changes to the structure of the
bea er material and will therefore damage the mixing bea er.
18

10.2 Maintenance
Allow the condensers to dischar e before you open the mixer.
Our vacuum mixers do not require servicing. Ma e sure the unit is ept clean and
that the rim seal for the bea er (vacuum seal) is not damaged.
10.2.1 Changing the filter
Fig. 5
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).
