Safety Notes

General Safety Notes

•All equipment undergoes final inspection and testing before leaving our factory. However,

if equipment is damaged during shipping or through any other circumstances, it must not

be used in service. Please check the device regularly for damages. Damaged parts

should be replaced immediately.

•All power/air/water/gas sources should be rated for the demands of the device as listed in

the technical data sheets. Maximum ratings must not be exceeded. All VDE (Verein

Deutscher Elektro-Ingenieure) standards should be followed. Equipment should be

grounded according to standards.

•Adherence to valid regulations regarding necessary checks (e.g. according to Accident

Prevention & Insurance or electrical equipment) is exclusively taken over by the

buyer/user of this product.

•This device has been designated to be used only for its intended purpose. All other

applications must be prohibited for safety reasons as otherwise the manufacturer’s

warranty expires.

•The device should be set-up in a clean, well-ventilated room, if necessary under a hood.

•Supporting surfaces should be straight, flat and adequately stable.

•Don’t place anything on top of the machine.

•To avoid injury, appropriate protection should be worn (e.g. gloves, safety glasses, safety

shoes, hearing protection etc.)

•If the machine is defective or working improperly it must be taken out of service. In case

of further use of the machine the owner will be held responsible for any consequential

damage.

•To prevent accidents from water, fire or explosion, all power/air/water/gas sources should

•In case of leaking water out of housing or tank shut down device and call service.

•Mobiles may lead to malfunctioning of the device and should be switched off near the

device.

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.

During long periods of non-use disconnect the device from mains supply.

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.

Mixing with reduced 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.

Pushing again PROG-key, settings are stored. Mixing time is stored and can be restarted

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 requirements).

Maximum filling level of the mixing bowl (10) is paddle top. (Note: please avoid overfilling,

see chapter 5 troubleshooting.)

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.

Activate the vacuum relief valve (9) for mixing with reduced vacuum:

−Opening the vacuum relief valve (9), vacuum is reduced.

−Closing the vacuum relief valve (9) vacuum is increased.

(Note: As soon as vacuum drops below -0,4 bar the bowl has to be held tight. Please

observe the gauge (2).)

Start mixing procedure with timer (1) key START (minus key). Mixing starts. Mixing 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 manually.) The pump switches off, initializing a flooding of the mixing

bowl.

The mixing bowl is ready to take out mixture.
