VACUUM PACKAGING MACHINES
1. SETTING UP THE MACHINE:
Before choosing the site for the machine, please consider that y ou wil l also need room
for packaged and non-packaged products apar t from the space needed for th e machine
itself.
Keep in mind that the machine must not be set up upon uneven ground. Especially wi th
mobile models, the weight of the pump mig ht 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 corresponds to the proper voltage and amperage of the
machine. GROUNDING INSTRUCTIONS: This appliance must be connected to a
grounded, metal, permanent wir ing system; or an equipment-grounding conductor must
be run with the circui t conductors and connected to the equipment-groundi ng terminal or
lead on the appliance. A quali fied electrici an should be c onsulted i f there is any doubt
as to whether an outlet box is properly grounded.
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.
The pump should not rotate more than 3 to 4 seconds in the wrong rotation or it
may cause serious damage. The proper r ota ti on i s indicated by an arrow on the
pump motor.
3.OPERATION:
3.1 Working 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 contai ning the product. (See figure
1). Then it is possible to inject neutral gas from the nozzles, if the product is delicate.
SIPROMAC INC.

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 r elation to the seal bar b y adj usting 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:
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.
9
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).

WARNING: All electrical work describe d i n thi s brochure should be done by
a QUALIFIED and AUTHORIZED technician
.
3.4 Daily cleaning:
For hygenic 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 nozzl es: 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:
4.1 Failure during pa ckaging cycle:
4.1.1 "VACUUM ERROR" message is displayed on LCD:
No pressure variation is picked up by the PCB transducer during the vacuum sequence
within a preset period of time.
- Check vacuum lines for potential leaks or kinks.
4.1.2 "GAS FLUSH ERROR" message is displayed on LCD:
No pressure variation is picked up by the PCB transducer duringthe gas flush sequence
within a preset period of time.
- Check gas flush and vacuum lines for potential leaks or kinks.
4.1.3 "ATMOSPHERE ERROR" message is displayed on LCD:
No pressure variation is picked up by the PCB transducer during the atmosphere
sequence within a preset period of time.
- Check vacuum lines for potential leaks or kinks.
4.1.4 "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.
17
4.2 Insufficient vacuum:
4.2.1 Leakage 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.
4.2.2 No 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 level is too low:
Pressure bar is jammed and closes opening of bag during evacuation.
4.2.3 Insufficient 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 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.
Caution:Verify connections of measuring equipment before verifing machine.
Most frequent points of leakage: lid gasket, damaged vacuum hose or loose hose
clamps.
18
4.3 Faulty seal:
4.3.1 Insufficient 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.
4.3.2 No seal:
Sealing wire burnt.
Faulty contact in sealing circuit.
Sealing transformer burnt through.
Contactor does not work.
4.3.3 Permanent sealing current:
Contactor is jammed check sealing transformer for damage through overload.
4.3.4 Seal 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).
Caution: Do not increase sealing time more than really necessary; higher temperature
4.4 Fault in the valve:
Vacuum or air valve does not open.
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.
will reduce working life of teflon and silicone rubber.
