3Operating instructions
Please refer to the short instructions supplied with your machine for
the operation of your Miknetum.
Also observe Chapter 1 Safety instructions!
Make sure that you are connected to the right machine
with your tablet PC!
Depending on the application programs, the drum is
moved automatically. While the program is running, no
person may stand within the working range of the

Miknetum MPR 1500
11
machine (front distance at least 1.2 m over the entire ma-
chine width).
Before the drum moves automatically, a 5 second alarm
(horn) sounds.
If the power fails when a user program is being executed
the machine will react as follows when the power supply
is reinstated: it will start up again automatically and the
program will continue from that point at which it was in-
terrupted by the power failure. The startup warning
(horn) will sound before this restart.
In its respective life cycle phases (transport, commission-
ing, setup, operation, cleaning, decommissioning,
care/maintenance, dismantling/disposal), this machine is
designed for single person operation!
When using this machine, no other person may be present
near the machine. The exception (2-man operation):
•Installation and removal of inside and outside lid
•Installation and removal of inside lid holder
•Installation and removal of tumbling arm
•Installation and removal of mixing arm
•Installation and removal of standard trolley support
•Installation and removal of protective gearbox cover
•Transport of machine and machine parts
•Maintenance work inside the drum
Depending on the user programs, temperatures down to -
25 ℃may be generated in the drum. Take the corre-
sponding precautions.
Do not touch the tumbling arm / mixing arm with your
hands or any object when they are moving! Their rota-
tional speed while the inside lid is open is restricted for
safety reasons!
Make sure before each lifting operation that the standard
trolley sits correctly in the standard trolley support of the
lifting unit and that it is locked!
No person may be present in the swivel range of the
drum!
The drum may be swivelled only when the outside lid is
closed and locked!

Miknetum MPR 1500
12
The drum can only be swivelled after the lifting unit has
moved to the bottom. Prior to starting a recipe, the lifting
unit must therefore be moved down again!
When emptying the drum corresponding appropriate pre-
cautions must be taken to ensure that no person stands in
the discharge area of the machine!
Make sure when mounting (or adjusting) the tumbling
arm, mixing arm (alternative blind plug), standard trolley
support as well as the chain on it that the pertaining lock-
ing pins are correctly locked!
No person may stand in the swivel range of the lids!
The operator must make sure that no persons, who do not
know the hazards of the machine or cannot anticipate
them, are about in the area of the machine!
If the drum is inclined downwards and you aerate the
drum or even open the inside lid, the goods will fall out of
the machine.
Remember that the outside lid and its lock may jump open
during unlocking!
Make sure each time work commences:
•that the outer lid is closed and locked!
•that the lid seal has been inserted correctly by
checking at program start whether a pressure loss is
indicated on the pressure display (if the machine is
able to create a vacuum). If this is the case, the seals
have been mounted correctly. Otherwise, check the
seals.
Please refer to the brief instructions supplied with your
machine regarding the manual operation of the manual
switch control.
The inside lid cannot be opened when there is a vacuum
in the machine or if it has not yet been fully aerated.
If you interrupt a program by pressing "Pause", you will be
prompted to aerate when "Open lid" is actuated. Only af-
ter the drum has been evacuated will you be able to open
the inside lid by actuating it again.
