Operation
6. Select the next function with the button
7.
Push the menu button to store all selected values and to return to the Home menu.
TURNING OFF MACHINE
1.
Turn the machine off by pressing the button.
2. The symbol on the display will start blinking.
3.
Push the button a second time and the pump will stop immediately.
4.
If no action is taken the pump turns off after 4 seconds.
5. Close the cover and the machine will initiate the cool-down phase and perform a number of vacuum cycles
while the cover stays closed and the machine will turn off automatically after about 15 minutes
Note: These cycles are necessary to cool down the machine and to allow any moisture in the oil of the
pump to evaporate.
FURTHER EXPLANATION OF PACKAGING CONCEPTS
SENSOR-BASED CONTROL
The actual air pressure in the chamber is measured by a sensor. The result of this measurement is digitally
indicated on the LCD display.
Normal air pressure is about 1000 mbar. The vacuum pump of the machine reduces this to about 2-5 mbar.
Depending on the program, the pressure by which certain functions need to take place can be programmed.
Examples are MAP gassing and Soft-Air. The air pressure in time-controlled machines is indicated by the
analog vacuum gauge.
TIME-BASED CONTROL
•
The standard control of a One-Program machine, as well as a Ten-Program machine, is time-based.
•
The Ten-Program time based machine can be converted into sensor-based operation by ordering the
optional sensor kit.
A time-controlled machine is programmed with a time value in seconds, according to which a desired vacuum
is reached. The vacuum measurement is indicated by the analog vacuum gauge. The reading of the analog
vacuum gauge is less accurate than the digital reading of a sensor-controlled machine.
• The Ten-Program machine can be retro-fitted with a sensor kit at a later date. The control system
recognizes the sensor and will automatically switch over to sensor-based operation.
•
In case the sensor should fail, the machine will automatically switch over to time-based operation.
PH2O PROGRAM FOR LIQUID PRODUCTS
•
Only for Ten-Program machines with sensor-based control.
• Specially designed for the packaging of cooled liquid products like sauces and soups at temperatures <
150C (600F).
Under normal air pressure (1000 mbar), water boils at 100°C. At that point, water transfers rapidly from a liquid
phase to a gas phase. At lower air pressure, boiling starts at a lower temperature as well as rapid evaporation.
To avoid product loss through evaporation and spillage, the P H2O program detects the point of boiling and
