3. Welcome
Thank you very much for your purchase of a Henkovac vacuum packaging machine. In order to guarantee
the reliability, longevity and robustness of your equipment, we only used materials of the highest
quality in the fabrication of your machine. During its design, it was our goal to make it easy to use and
simple to maintain.
Based on your purchase of this machine, we assume that you are familiar with the fundamentals of
vacuum packaging. For additional information and guidance about vacuum packaging applications, we
recommend that you contact your dealer.
3.1. Service from your Dealer
For technical support, please contact your dealer.
Please have the following information available:
• Machine type
• Serial number
You can locate the serial number on the front page of the original manual. In addition, you can find it on
the identification plate on the right-hand side or back-side of your machine.
3.2. YouTube Henkovac Channel - Instruction and Service Videos
Instructional videos are placed onYouTube for the operation and service of your machine. You may locate
these videos on the YouTube website under “Henkovac Channel”.
4. Installation of Machine
General
• Level the machine on a flat firm surface
• Position the machine in such a manner that the pump is unobstructed and properly ventilated
• Engage the locks on the wheels, if so equipped
• Check the oil level in the pump; add oil if necessary
- Never operate the machine when the oil level is low
Table-Top Model
Mobile and Double-
Chamber Models
Oil sight glass
Oil sight glass
Wheel locks
Electrical Connection 3-phase vacuum pump
If the machine is incorrectly hooked up to a three-phase electrical connection,
the pump will make excessive noise. If this happens, take the following steps:
• Turn the pump off immediately
• Switch the phase wires
• Make sure that the rotation direction of the pump matches the arrow on the
motor housing

Turning on Machine
• If so equipped, like some mobile and double-chamber models, turn on the main
power switch on the back of the machine
• Push the on/off button on the control panel of the machine
4.1. Gas Connection for MAP Applications (Modified Atmospheric Packaging)
• Connect the gas supply line to the inlet on the back of the machine
• Maximum pressure: 1 bar
• Anchor the gas cylinders securely to prevent them from falling over
• Make sure that the work area is well-ventilated
• To assure that you use the appropriate gas for your application, consult
your dealer or gas supplier
• Assure a good connection and use high-quality materials
4.2. Compressed Air Connection for Additional Sealing Pressure
• Additional sealing pressure is usually recommended for MAP applications
only
• The M4-M8 and the D1-D6 models with the option Gas/MAP are standard
equipped with a compressed air inlet
• Extra sealing pressure is not necessary and not available for the Table-Top,
M1, M2, M3
• Consult your dealer for installation details
• Maximum pressure: 1 bar
• Assure a good connection and use high-quality materials

6. Digital Control with LCD Display
Some Henkovac vacuum machines have a control system with just one Program (P1). Other machines
have an optional expanded control system, which can accommodate up to 9 custom programs (P1-9).
6.1. One-Program Control System
Henkovac machines with the One-Program
control system can be programmed for the
following 2 functions:
1. Vacuum time (seconds)
2. Sealing time (seconds)
• The values for vacuum and sealing times are selected by the user and saved in program P1
• During operation, the LCD display will show symbols to indicate the active function and the progress
of the packing cycle
• The actual vacuum pressure is indicated by the analog vacuum gauge
Plug & Play
• When turning on the machine for the first time:
- running time of the vacuum pump is pre-set at 30-40 seconds and the sealing time at 2 seconds.
Vacuum is indicated on the analog vacuum gauge.
• When turning on the machine after that, program P1 will contain the most-recently used settings
• The vacuum and sealing times are easily adjusted to match the needs for the application

Menu Button
- Confirms and saves the entered values for vacuum and sealing times
- Returns to the Home menu
6.2. Operating the Machine with One-Program Control System
On:Turns the machine on
- The machine will start up in the most-recently used program
- The pump of a machine with a transparent cover will start when the cover is closed
Off:Turns the machine off
- When pressing the button once, the symbol will start blinking and the pump will stop after
about 4 seconds
- When pressing the button a second time, the pump will stop immediately
- Closing the cover will initiate the cool-down phase; the machine will complete a number of vacuum
cycles before turning off automatically
Stop-function
- Stops the machine at any point in the packing cycle and aerates the chamber
Reset-function
- While programming, resets the program value to its original setting
Press the menu button to return to the Home menu
Stops the current function and initiates the next step in the cycle
- By pressing the of the sealing button , the vacuum function stops and the program jumps to
the sealing function
- While packing sauce or soup, the package may be sealed as soon as product boiling is detected
Entering the desired vacuum time
- By pressing the + or – of the vacuum button , the vacuum time can be increased or decreased
The selected value is confirmed and saved by pressing the menu button
- Press the button to reset the original value
Entering the desired sealing time
- By pressing the + or – of the sealing button , the sealing time can be increased or decreased
The selected value is confirmed and saved by pushing the menu button
- Press the button to reset the original value

Service Symbol
- After a number of operating hours or packing cycles, the service
symbol will briefly appear on the display when the machine is
turned on. In addition, the display indicates how many hours or
cycles remain before an oil change is required
When turning off the machine with the button, the symbol will start blinking
- The pump will stop after about 4 seconds
- Press the button a second time and the pump will stop
immediately
- Close the lid; the machine initiates the cool-down phase and per-
form a number of vacuum cycles before turning off automatically
- These additional cycles allow any moisture in the oil of the
pump to evaporate. This increases the longevity of the machine and minimizes the need for oil
changes and pump maintenance
- Except for regularly changing the oil in the pump (important!), the machine requires little other rou-
tine maintenance
6.3. Ten-Program Control System
In addition to vacuum and sealing times, Henkovac machines with a Ten-Program control system may
be programmed for several additional functions. Each of the 9 customizable programs is either
1. time-controlled
2. sensor-controlled
6.3.1. Time-Based Operation (vacuum gauge: mbar)
• The values for vacuum and sealing time, as well as
the values for several optional functions, are selected
by the customer and saved in any of 9 customizable
programs P1-9
• When operating a packaging machine with a time-based program, the actual vacuum pressure is indicated by
the analog vacuum gauge.The number of seconds of vacuum time remaining is shown on the LCD display
Plug & Play
• When turning on a time-based machine for the first time, it will start up in the PA program AUTOMATIC . This
is a pre-set factory program with 30-40 seconds vacuum time and 2 seconds of sealing time
• When turning on the machine after that, it will start up in the most-recently used program
Optional installation of a Sensor or Soft-Air
• A machine with a time-based control program can be upgraded to sensor-based operation at a later
date by installing the optional sensor kit
• The Soft-Air feature can also be installed at a later date by ordering the optional soft-air kit
6.3.2. Sensor-Based Operation (digital display: mbar)
• When operating a packaging machine with a sensor-based program, the actual vacuum pressure is digi-
tally shown on the LCD display in mbar (standard setting) or in % vacuum
Plug & Play
• When turning on a sensor-based machine for the first time, it
will start up in the PA program AUTOMATIC . This is a pre-set
factory program with 5 mbar of vacuum and 2 seconds
of sealing time
• When turning on the machine after that, it will start up in the most-recently used program
Optional installation of Soft-Air
• The Soft-Air feature can also be installed at a later date by ordering the optional soft-air kit
