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 ma-
chine (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 lid
•Installation and removal of 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

Miknetum MPR 500

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 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 aid and that it is locked!
No person may be present in the swivel range of the
drum!
The drum can only be swivelled after the lifting aid has
moved to the bottom. Prior to starting a recipe, the lifting
aid 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 lid!
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 lid, the goods will fall out of the
machine.
Each time before you start working, make sure that the lid
seal has been inserted correctly. For this, check during
program start whether a pressure loss is indicated on the
pressure display (if the machine can create a vacuum). If
this is the case, the seal has been mounted correctly. Oth-
erwise check the seal.

Miknetum MPR 500
13
Please refer to the brief instructions supplied with your
machine regarding the manual operation of the manual
switch control.
The 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 lid by actuating it again.
The drum can be set to any position between 30° and
102° (= discharging position) so that it can be used for
any operating process.
The tablet PC may only be operated by finger touch or
with a stylus. Using any objects (e.g. knife) for operation
is prohibited!
