F1:

When this code is displayed, the normal packing cycle has somehow been interrupted.

Examples- the lid being opened to early

F2:

This code indicates that the sensor is not working properly. 

Examples- during start-up of the machine the condition of the sensor is being checked. If the checked values are outside their scope, the failure notice F2 will be displayed.

Rp: 

This code will be displayed when the operating panel is not able to get the correct memory data needed for starting up.

 How to fix Rp error code issue: Switch machine off and on again to check if it can get the correct memory. 

Press the Reprog button. By pressing this button the machine will reset to default setting all other programs will be overwritten. 

One of the service functions is the operation hours counter in order to be able to automatically indicate regular service requirements. This functions sets the number of hours that the pump runs (per 10 hours). Once the number of hours set has been exceeded, the message [OIL] appears on the display. The machine can still be used as usual but the message will keep reappearing on the display.

The factory setting for the program operation hours counter is 500 hours. The following steps can be followed to activate the operation hours counter or to reset it:

Press the FUNCTION SELECT Key for at least 3 seconds.

After 3 seconds the number of operating hours (per 10 hours) will be displayed for about 2 seconds.

After 2 seconds the originally set number of hours will be displayed (per 10 hours).

When the operation hours counter is turned off, the number of operating hours will not be displayed, instead the message [OFF] will immediately appear after pressing the key for 3

seconds.

The original setting can be modified using the + and – keys (between 0 and 990 hours). If set to 0 then the next time
[OFF] will automatically be displayed. The new settings are stored by using the REPROG Key.

The actual operation hours are then also reset to zero.

After pressing the REPROG key, the control panel automatically switches over to operation mode

VACUUM PUMP MAINTENANCE

It is very important to regularly service the pump to ensure extended and correct operation. The following activities are
essential for correct maintenance. If the machine is used regularly then it is advisable to have the pump fully inspected at
least once a year by the supplier to ensure extended and problem free operation. 

Conditioning Program

The conditioning program ensures that the pump is thoroughly rinsed. During the program the pump and oil reaches operation temperature so that the oil can better absorb any moisture and contaminants and filter them. The high
temperature enables any moisture in the pump to evaporate minimising the risk for rust spots.
The program lasts 15 minutes and it is advisable to run it at least once a week.

Turn on the machine, press the key [conditioning program], and close the lid.

The program runs automatically. During the program the large display will display moving lines.
The program can be interrupted at any time using the [STOP] key. It is however important for the sake of good
maintenance that the program completes a full 15 minute cycle and therefore advisable only to interrupt the cycle for
something urgent.
It is also advisable to run the program before using the machine for the first time, after the machine has been stationary
for a lengthy period of time, and especially prior to changing oil.

1. Turn the machine on with the ON/OFF switch. Heat up the pump with the condition program when machine has
stood idle for some time.

2. Fill the vacuum bag with product. Select the correct format bag that easily fits around the product but is not too
large for the product. Ensure hygienic conditions during this operation. Packaging materials, product and hands
must be clean and if possible dry.

3. Lay the vacuum bag on the working plate. The open side must be laid over the sealing bar or silicone holder. The
bag may however not extrude from the chamber. If the product is a lot lower than the height of the sealing bar or
silicone holder then insert plates which are supplied standard with the machine can be used. This makes the
operation easier and reduces the cycle time.

4. The vacuum bag must be laid without folds over the sealing bar or silicone holder.

5. For a gas flush system the opening of the vacuum bag must be pulled over the gas
nozzles (see illustration).

6. Multiple vacuum bags can be placed over the sealing bar/silicone holder if the
sealing bar/silicone holder is longer than the vacuum bag. Vacuum bags may not
however be laid on top of each other on the bar/holder. If there are multiple bars/holders
then all bars/holders can of course be used during the same cycle.

7. Use the [PROG] key to choose the desired program. See page 17 for instructions about programming.

8. Close the lid and the machine automatically runs through the full cycle of all activated functions. The lid opens
automatically when the last function “ventilation” has been completed.

9. If necessary the cycle can be partially or fully interrupted by pressing the [VACUUM STOP] key or the [STOP] key.
The [VACUUM STOP] key interrupts the active function (vacuum, gas flushing, sealing, or soft-air ventilation) and
automatically continues with the next function.
The [STOP] key interrupts the entire cycle and goes immediately to the ventilation function.

10. After cycle completion, the packed product (or products) can be removed from the machine.

11. If the machine is equipped with a cut-off sealing system then the remaining flap on the vacuum bag can be torn off.

The lid can stick due to moisture suction. Moisture suction can be elliminated by: 1. Removing all product from the deck. 2. Cleaning all parts of the deck. 3. Drying all parts of the deck. Run a cycle. Does the lid continue to stick? If the answer is no, the lid was sticking due to moisture suction. We recommend cleaning the deck at the end of each daily use or as needed if sticking occurs during operation. If cleaning the deck did not change the issue, check the condition of the springs. The springs may need to be adjusted. Also, inspect all spring brackets. Any damaged springs or brackets should be replaced.

If you are noticing a strong oil smell, there are numerous possiblities:

1. Power/Voltage
   What is the power in your building?
   What is the voltage of your machine?
   
   Operating the machine with the wrong voltage can damage motor and pump. Contact a qualified technician or electrician to fill out the Power Chart Form » and compare it to the machine's voltage. You can find the voltage on the serial plate on the back side of the machine.
   
   
2. Pump Oil
   What type of pump oil is in your machine?
   What is the room temperature where the machine is being operated?
   
   Your pump may overheat if operated with lighter oil in higher temperature environments. A strong oil smell would be a sign for it. If this is the case, you have to change the oil and replace the oil filter.
   
   
3. Machine Level
   The machine can only run properly when it is leveled so that the oil can be distrubuted evenly inside.

4. Check Filters

     If filters are not properly installed, it could cause there to be a strong oil smell.
