these operating instructions
2.2.
Installation
The tumbler model HR 2035 has to be installed on a plain, horizontal, non-slip and stable
surface. If necessary the machine has to be screwed tight in addition.
Recommended height of the working surface about 800 mm. Pay attention to the required counter
space.
2.3.
Electrical installation
Before you plug in the machine, you have to check if the current supply is the same as indicated on
the rating plate. In case there are discrepancies you have to inform the supplier or technical service.
Under no circumstances plug in the machine!
The socket-outlet has to be equipped with earthing contact. It has to be connected according to customary
regulations.
A defective socket-outlet may damage the machine or endanger the operator.
The socket has to be installed at a place which can be reached easily by the operator, so that in case of
emergency the plug can be pulled out quickly. In any case the socket must not be under the counter or at a
place which cannot be reached easily.
In case it is necessary to exchange the plug, this has to be done by an electrician or the after sales service.
2.4.
Oil filling of the vacuum pump
The vacuum pump is generally supplied without oil filling and it has to be filled before the first operation of the
machine.
After having filled the vacuum pump with oil the machine must not be tilted more than 400as
otherwise oil gets into the vacuum chamber and due to this the vacuum pump could be
destroyed.
Pay attention to this fact especially when moving the machine to another place or in case of a repair. If the
machine has to be tilted you have to let out the oil before.
For filling the pump screw off the filling screw "1"
and fill in oil supplied with the machine.
The viewing glass "2" has to be filled approximately 3/4.

3.3.
Filling of the drum
Never fill the drum more than half of the height of the drum. In case the maximum filling height
is exceeded there is a risk that the vacuum pump is sucking liquid. As a result the pump will be
destroyed.
3.4.
Tilting lever
In order to avoid heavy lifting of the filled drum we recommend to fill the drum when it is mounted on the basic
device. For this purpose there is available at the right side a tilting lever in order to lift the drum in filling position.
For filling the drum the device is tilted upwards as shown below. Then position the drum on the coupling as shown
below for filling it.

After that mount the chicane and fill the drum. Place the lid on top of the drum and lock it as shown on the
following photos. Before putting on the tube tilt the device in any case downwards.
In case there should come out liquid under no circumstances put on the tube. Overfilling!!!
3.5.
Connection of the connecting tube
Engage the connecting tube into the tube connection of the lid. In case there should come out liquid of the
open end of the connecting tube the maximum filling height is exceeded in any case. In this case you have
to empty the drum until the maximum filling height is reached.
Engage now the connecting tube into the plug-in coupling of the water separator.
3.6.
Control
Before starting the operation of the machine you have to control again the following points:
1. Is the drum positioned correctly on the coupling?
2. Is the connecting tube engaged correctly on both sides? Is there any liquid in the tube?

Meaning of the display
In case you have not yet made any changes in the several programs the display shows the following digits:
01 00 00 000 000
This means in detail the following:
PLU Nummer –PLU number
Arbeitszeit –time work
Pausenzeit –time pause
Gesamtzeit –total time
Vorlaufzeit –lead time
When switching the machine on at the main switch the machine is generally in the PLU mode of the first PLU
number. This means that pre set programs can be called up . The electronic control can store 11 different PLU
programs and 1 manual program.
The first two digits show the actually adjusted PLU. In this case PLU No. 01.
During the program flow the PLU number does not change. All other numbers are changing continuously after
having started the machine and always show the actual status.
The following two numbers are showing the programmed working time, 05 minutes. This is the time while the
drum is turning. Each minute the indication will be reduced by 1 until the display shows zero. Then the drum stops
immediately.
The two following digits are showing the programmed breaking time. As soon as the drum stops the breaking time
starts. When the pre set number of cycles is reached the drum is aerated. Also the breaking time is reduced by 1
per minute until the display shows zero. After that the cycle starts new.
The next three digits show the calculated total time, in this case 043 minutes. By means of this you have an
indication when the program will be finished.

Never take off the drum from the machine before you have switched off the machine at the
main switch.
Never touch the driving and guiding rolls while the machine is in operation.
5.4.3.
Modifying a selected PLU number
In case the factory values do not meet your request you can change the single values at any time.
First adjust the PLU number you would like to modify.
Then push the button ’change indication’ and keep it pushing for at least 6 seconds.
The indication changes and shows:
Time Work 05
Now you can change the working time with the buttons ’+ and –’ in minutes. Adjustable between 1 – 99.
With the button ’change indication’ you get to the next indication.
Time Pause 03
Also here you can change the time with the buttons ’+ and –’ in minutes. Adjustable between 1 – 99.
With the button ’change indication’ you get to the next indication.
Num. Cycles 05
Here you adjust how many times the program flow is repeated. When you enter 5 this means the drum is turning
five times and there will be five times a break. Also here you can change the value with the buttons ’+ and –’.
Adjustable between 1 –99.
With the button ’change indication’ you get to the next indication.
Lead Time 000
Remember: This is the time running before the real program starts working. Also here you can change the value
with the buttons ’+ and –’in minutes. Adjustable between 0 – 999.
With the button ’change indication’ you get to the next indication.
VAC. CYCLES 02
Here you can adjust how many cycles should be effected without aerating the drum. In this example the drum is
aerated after each second cycle. Also here you can change the value with the buttons ’+ and –’. Adjustable
between 1 –20.

Seite 13
With the button ’change indication’ you get to the next indication.
Time 1 Vac 65
Here you adjust how much time the vacuum pump is working after having started the program and after each
aerating. Indication in seconds. Adjustable between 1 –99.
There is a difference between vacuum time 1 and vacuum time 2. The first vacuum time is used during the
program flow only when the program is started and after one aerating. In this example the machine is effecting the
following program after having pushed the button start / stop: start of the vacuum pump for 65 seconds (Time 1
Vac), turning of the drum for 5 minutes, stopping of the drum for 3 minutes, start of the vacuum pump for 25
seconds (Time 2 Vac, this time is adjusted in the next step), turning of the drum for 5 minutes, stopping of the
drum, aerating of the drum for 30 seconds (Time Airing, this time is adjusted in the step after next), three minutes
break, start of the vacuum pump for 65 seconds (Time 1 Vac), turning of the drum for 5 minutes, etc. until 5
cycles have been executed. At the end of the program the drum will not be aerated in order to prevent a probable
development of germs. Aerating of the drum is only effected when pushing the start / stop button. As a hint for this
status the display shows at the end of the program PUSH STOP
With the button ’change indication’ you get to the next indication.
Time 2 Vac 25
Here you adjust how long the vacuum pump should be switched on after the cycle breaks in which the drum was
not aerated. Indication in seconds. Adjustable between 1 –99.
The air contained in the meat is sucked out during the process which results in a reduction of the vacuum. In
order to achieve again a complete vacuum the vacuum pump switches on for this time before the drum starts
turning.
With the button ’change indication’ you get to the next indication.
Time Airing 30
Here you can adjust how long the drum should be aerated when the "Vac Cycles" are reached.
In case you prefer to keep a remaining vacuum the time has to be adjusted accordingly low. If you prefer
complete aerating accordingly high. Also here you can adjust the time with the buttons ’+ and –’. Indication in
seconds. Adjustable between 1 –99.
With the button ’change indication’ you get to the next indication.
Pre-Time 00
Here you can adjust whether you want a pre-working time under vacuum before the normal cycles starts. If you
adjust a time here the program will do the following: After pushing the start button the lead time will expire if a lead
time is adjusted. The vacuum pump is switched on for the time adjusted under Vacuum Time 1 and the drum will
be evacuated. After that the drum starts turning for the adjusted Pre-Time. After this time the machine starts with
the normal program. Indication in minutes. Adjustable between 0 –99.
When pushing again the button ’ change indication’ the display changes to “Time Work”. Now you can check
again all values by pushing several times the button . If all values are correct do not touch any button for 2
seconds and all modified values are saved and the display returns to the basic indication.
The procedure can be effected with each PLU number.
5.5.
Working in the manual mode
By means of the button ’PLU’ you can change from the manual mode to the PLU mode and the other way around.
In the manual mode the display shows the letter MA instead of the PLU number and it looks as follows:
MA 05 00 000 000
You should choose this mode in case you are in need of a certain program only for a short time and you do not
want to reprogram your PLU numbers.
The working process is the same in both modes.
5.5.1.
Starting the manual mode
Also in the manual mode you can start the machine at any time by pushing the button
’automatic on / off’.
You can see that the machine started as the corresponding times are now shown on the
display.
The program flow can be interrupted at any time by pushing the button "automatic on / off". The program will be
interrupted immediately then and the drum will be aerated.
When starting the program flow again the cycle starts from the very beginning.
Risk of bruises.

5.5.2.
Modifying the condition in the manual mode
The modification of the conditions in the manual mode is effected in the same way as it is done with the
modification of a PLU number.
Only the start of the modification is different. In case you would like to modify the manual mode only push shortly
the button ’change indication’.
The indication changes and shows:
Time Work 05
Now you can change the working time with the buttons ’+ and –’. All other steps are the same as the steps within
the PLU mode.
5.6.
Note
Here again the following note:

a probable development of germs. Aerating of the drum is only effected when
pushing the start / stop button.
As a hint for this status the display shows at the end of the program PUSH STOP
6.
Cleaning
Before initial operation and after a longer period of standstill the machine has to be cleaned carefully.
With permanent use of the machine you have to clean it at least one time per day or if necessary also a few times
per day. For cleaning proceed as follows:
6.1.
How to proceed with cleaning
Switch off the machine.
Pull off the plug
Take off the drum from the machine
6.1.1.
Cleaning of the machine
Wipe the machine with a moist cloth and dry it afterwards.
Note: For cleaning only use usual washing-up liquids. Do not use scratching or scouring cleansing
agents or devices.
The machine is only drip-proof. Therefore do not use high pressure cleaning devices, water
hoses or similar devices. Furthermore you must not pour water over the machine. Danger of
short circuit or machine defect. In such cases any claims regarding warranty will be refused.
6.1.2.
Cleaning of the drum
Disengage the connecting tube on both sides and take it off.
Take off the drum from the basic device.
Take off locking ring and lid.
Take out the chicane of the drum by slightly pulling it.

Reassembling the parts
Reassemble the parts in reverse order.
7.
Maintenance
Clean the machine at least one time per day.
Slightly oil the couplings of the connecting tubes one time per day.
For oiling the machine only use acid free oil.
Check the oil level of the vacuum pump daily.
After each filling of the drum check the water separator.
7.1.
Oil change at the vacuum pump
When the oil level has sunk under the lower edge of the viewing glass there has to be made an oil change.
Also if you find out during the daily control that liquid has penetrated into the pump you have to make an oil
change. You will recognise this by a milky white colour of the oil. In this case change the oil immediately as
otherwise there is the risk that the pump gets rusty inside. In this case any warranty claim will be refused.
7.1.1.
How to proceed the oil change
Lift up the machine by using the tilting lever and place a flat
collecting container under the waste oil screw. Loosen this
screw by means of a hexagon socket screw key. Now let
the machine down. Leave it like this for at least two hours,
or even better during the whole night. Screw tight the waste
oil screw, open the oil filling screw. Fill in new oil,
BV 32 app. 0,2 litre, through the oil filling screw 1. Control
the oil level at the viewing glass 2, it should be filled up to ¾.
Then screw tight again the filling screw with a hexagon socket screw key.
7.2.
Water separator
In case the drum should have been overfilled by error, the water
separator tries to hold back the sucked liquid. For this reason you
have to control each time before starting the program and before
the vacuum pump works the first time if water is accumulated in
the water separator. If this should be the case interrupt the
program immediately and reduce the filling level in the drum.
Also when working correctly it can happen that water will be
accumulated in the water separator. It has to be let off in any case.
In order to let off the water proceed as follows:
Switch off the machine.
Make sure that there is no more vacuum. The vacuum meter has to show zero. If there is still a vacuum in the
machine you have to remove the connecting tube from the drum. Only if the vacuum escaped completely from the

Seite 16
machine open the drain plug 1, size of key SW 14, at the lower end of the water separator. The water drains off
outwardly.
When the water has drained off completely close again the drain plug.
In case the container should be dirty loosen the upper screw 2with a key size SW 10, turn off the container, clean
it and fix it again.
Now you can engage the connecting plug again and restart the machine.
