Specific Safety Instructions
•Don’t mix any alienated material or material containing solvents, dangerous to health.
•The pump and other conducting components are not explosion-proof. Application with
burnable substances is therefore prohibited.
•Don’t use any high-viscosity material leading to a considerable decrease in mixing speed.
•If the machine gets unusually hot, turn off immediately.
•Don‘t put your hands into the running driving axle and never put the mixer on the support
without a bowl.
•Don’t overfill the mixing bowl.
Note:
The mixing bowl is dishwasher-proof and may be cleaned with solvent-free cleaning
agents. The mixing bowl is non-resistant to some chemicals like e.g. concentrated mineral
acids, aromatic hydrocarbons and chlorinated hydrocarbons as ester, ether and ketone.
Keep the housing clean and dry.
Installation
The electric equipment is being delivered fully installed. The sealed plug can be connected
directly to the mains supply 230 V/16 A. For installation please refer to chapter 2.
Installation
The device can be used as a wall-mounted (see chapter 12 wall mounting) or bench-top
unit.
Use the device only in a dust-free environment.
Preparation for Installation
Insert the attached power cord into the power outlet (6) of the device.
Put the power plug of the RETOMIX MINI into a socket. Now the device is ready for use.

Operation
Mixing with vacuum
Use timer (1) to set mixing time.
Programming: Press key PROG.
−Press once –hours
−Press twice –minutes
−Press three times –seconds
−Use + and –to change settings for hours/minutes/seconds.
Pressing again PROGR, settings are stored. Mixing time is stored and can be started at
any time.
Special feature:
Speed display (11) indicates zeroes: Push and hold all three keys for a couple of
seconds. Display indicates time:
00:00 00
Continuous mixing is started by pressing Start when display indicates: 00:00 00.
OPTION: Mixing time may be changed with the speed control (12) even during running
mixing procedure (according to material).
Maximum filling level of the mixing bowl (10) is paddle top. (Attention: avoid overfilling,
see chapter 5 overfilling.)
Insert the mixing bowl (10) into the bowl support (7), slightly pressing the bowl. Vacuum
pump starts automatically after a couple of seconds. You can release the bowl. (while
observing the gauge (2). As soon as vacuum drops below -0,4 bar the mixing bowl has to
be held tight.)
Start mixing procedure with timer (1) key START (minus-key). Mixing starts and may be
interrupted at any time with the key STOP (minus-key).
After time has elapsed the paddle stops. The device emits a beeping sound twice and the
vacuum pump maintains the vacuum.
Activate the switch for flooding (3) until the pressure at the gauge (2) has returned to „0“.
(while observing the gauge (2). As soon as vacuum drops below -0,4 bar the mixing bowl
has to be held tight.) The pump switches off, initializing flooding of the mixing bowl.
The mixing bowl is ready to take out mixture.

has to be held tight manually.) The pump switches off, initializing a flooding of the mixing
bowl.
The mixing bowl is ready to take out mixture.

11
Mixing bowl for alginates (special accessories)
In order to prevent power residues from falling from the edge of the bowl into the mixed
alginate, first of all water and power should be premixed without vacuum.
Put power and water into the bowl, mixing it with reduced vacuum (Procedure see
chapter 4.2.)
Mixing time is dependent on used material (see manufacturer’s indications).
During the first ten seconds a lower mixing speed of approx. 400 min-1 should be
selected, then speed should be increased to 600 min-1.
Troubleshooting
Device doesn’t start. (Power switch (2)
doesn’t shine after switching on).
a. No power at the socket (Check fuse of
the building).
b. Machine’s (5) has blown (unplug the
machine and replace the fuse. The fuse
holder is loacted at the device’s plug).
Bubbles in investment material (low
vacuum).
a. Dirty lid surface of the mixing bowl →
clean it.
b. Dirty gasket at the bowl support (7) →
clean it.
c. O-ring of mixing bowl (10) is untight –
clean it.
d. Adjust vacuum relief valve (9).
Bowl isn’t fixed although gauge indicates
max. vacuum.
