VACUUM PACKAGING MACHINES
1. SETTING UP THE MACHINE:
Before choosing the site for the machine, please consider that you will also need room for packaged and non-packaged products apart from the space needed for the machine itself.
Keep in mind that the machine must not be set up upon uneven ground. Especially with mobile models, the weight of the pump might then cause warping of the machine.
Then the lid will not fit correctly.
Before starting to work, check the oil view glass on the pump, if there is a sufficient quantity of oil in the pump. Never use oil other than recommended by the producer. Never exceed maximum quantity of oil indicated, when adding or changing oil. Verify weekly.
Normal ambient temperature for the vacuum pump is between 10 to 70oC.For temperature below 10oC; it is recommended to use synthetic oil. Please consult factory and pump manufacturer manual for more information or when ambient temperature are outside normal limits.
2. ELECTRICAL CONNECTION:
Electrical connections must be made by qualified personnel. This person must make sure that the electrical entries correspond to the proper voltage and amperage of the machine. GROUNDING INSTRUCTIONS: This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance if it will not fit the outlet; have a proper outlet installed by a qualified electrician.
All vacuum machines are supplied with an electrical schematic drawing. An important step in connecting the machine is to make sure that the pump turns in its correct rotation.
7
The pump should not rotate more than 3 to 4 seconds in the wrong rotation or it may cause serious damage. The proper rotation is indicated by an arrow on the pump motor.
3.OPERATION:
3.1Working principles:
A vacuum packaging cycle is made of 3 stages. First the vacuum is made, the air is completely taken out of the chamber and from bag containing the product. (See figure
1). Then it is possible to inject neutral gas from the nozzles, if the product is delicate. Finally, a mechanism pushes the sealing bar to the rubber support to seal the bag.
To obtain nice packages, the products and the bags have to be of proportional sizes. The bag's opening should never exceed 50 cm(2") past the seal bars. The product should be centered in height in relation to the seal bar by adjusting the spacers provided.
To obtain a good seal, make sure that no residue of fat is left between the bag's inner sides where sealing is done.
3.2 Special packaging:
8
3.2.1 Gas flushing (option):
There is an atmospheric pressure of 1 kg/ sq. cm (14 lbs/sq. inch) upon products when fully evacuated. Products which can be damaged by high pressure must be packaged with a partial vacuum, or the pressure must be counterbalance by inflating the bag with gas (nitrogen or carbon dioxide) before sealing after evacuation.
For gas flushing, the bags are placed on the sealing bars, the open end placed over the gas nozzles mounted alongside the sealing bar. After evacuation, the vacuum valve closes and the gas valve opens. Gas time (sec.) can be set in the program menu.
The necessary gas tank and pressure valve mounted on tank is not supplied, The pressure of the gas regulator should be set at approximately 1/3 kg/sq. cm
( 5 lbs/sq.inch.). Each machine has an adaptor for gas connection when gas flush option is ordered.
3.2.2 Electrical bag cut (optional):
This option is used to obtain a package that the excess bagtail is cut off close to the seal (cannot be used with top and bottom sealing).
3.3 Vacuum packaging operation:

WARNING: All electrical work described in this brochure should be done by a QUALIFIED and AUTHORIZED technician.
3.4Daily cleaning
For hygienic cleanliness, it is imperative to clean chamber and spacers daily. Also clean the lid rubber to assure tight seat of the lid.
Cleaning instructions for gas injection nozzles: Periodically on a regular basis the gas injection nozzles must be removed with the connection tube and soaked in a food grade soap and water solution, then dried and re-installed.
4.TROUBLE SHOOTING:
4.1Failure during packaging cycle:
4.1.1 "COVER DOWN ERROR" message is displayed on LCD(manual units):
The input signal of the down position switch has been lost during cycle execution.
-Check limit switch adjustment.
4.2Insufficient vacuum:
4.2.1Leakage in the bag:
Most frequently, insufficient vacuum in bags is due to leakage in bag and not due to any fault of the machine.
Pin-hole leak for which there is no obvious explanation is due to faulty bag material.
Pin-hole leak caused by sharp edge of the product (bone, etc.).Use bone-guard or thicker film.
Tear in bag by careless handling (sharp edge on filling table, damage made by retailer or customer).
Leakage in lateral or bottom seal, complain to supplier of bags or film.
4.2.2No leakage in the bag:
Bag is too large, therefore the surplus of air remains visible (there is surplus of air in 0.4% of the bag volume in each bag). Use bags of suitable size.
Vacuum time is too short:
Pressure bar is jammed and closes opening of bag during evacuation.
4.2.3Insufficient vacuum in chamber:
If troubles described under 4.2.1 and 4.2.2 do not apply, there is something wrong with the evacuation. To find the leakage quickly, check for leaks with a precision
15
vacuumeter, going back step by step from the chamber to the pump.
At the chamber (measuring point at base of valve) at maximum time of evacuation. If more than 6 torr, proceed directly to the pump, if more than 3 torr: have pump service by pump supplier. If pressure at pump is good, reconnect hoses to pump and measure again.
Verify at vacuum hose connections and valve connections.
When proceeding this way, starting from pump, loss of pressure per step must not exceed 0.5 to 1 torr.
Warning: Verify connections of measuring equipment before verifying machine.
Most frequent points of leakage: lid gasket, damaged vacuum hose or loose hose clamps.
4.3Faulty seal:
4.3.1Insufficient seal:
Damaged teflon or silicone rubber.
Sealing pressure too low, bellows leaking or pressure bar jammed.
Leakers in seal: heating wire mechanically damaged (knicked) or silicone rubber uneven.
4.3.2No seal:
Sealing wire burnt.
Faulty contact in sealing circuit.
Sealing transformer burnt through.
Contactor does not work.
4.3.3Permanent sealing current:
Contactor is jammed check sealing transformer for damage through overload.
4.3.4Seal does not stick:
Insufficient layer of polyethylene (inferior quality of bags).
Seal area extremely contaminated by fat or meat juice. Use filling aid.
Sealing temperature is too low (when using very thick films).
Warning: Do not increase sealing time more than really necessary; higher temperature will reduce working life of teflon and silicone rubber.
4.4Fault in the valve:
Vacuum or air valve does not open.
16
Check whether there is voltage on the magnetic valves during their period of operation.
If there is no voltage a wire is broken or the PC board is damaged.
Lid does not open at the end of the cycle; air enters, but there is still 20 - 40% vacuum in chamber. Vacuum valve does not close.
4.5MC40 Control board failure
NOTE: Refer to menu structure on page 13.
This board software is allowing access to a "Diagnostics Menu". Only qualified service technicians are authorized to access this menu by entering a security password.
By acceding either the "D1 input test" feature or the "D2 output test" feature, a trained technician will be able to quickly know the origin of the problem: pump,
sealing system, pneumatic problem, security switches problem, etc...
Keep in mind that in most cases trouble is due to a leakage, loose electrical Keynesian or evident damage to the main component: vacuum pump, valves..., electrical contactors, thermal overload, fuses holder or transformer.
For assistance do not hesitate to contact your local service technicians.
5.Regular maintenance:
Routine controls to be made at regular intervals: Check teflon for wear.
Check silicone rubber for burnt spots and smooth even position.
Check pressure bar for jamming.
Check lid sealing for damage and hardened spots. Check switch-point of micro switch, adjust if necessary.
Check evacuation hose for damage (contraction of diameter, or abrasions). Check vacuum connections for tightness.
Check oil in pump (oil level in view glass; add if necessary. Regular change of oil - necessity indicated by change of color).
Check vacuum in chamber with precision vacuumeter. Check function of cycle with various settings of timers.
