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.
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 operating temperature for the 350/350D is 4C to 32C (39F to 90F).
Vacuum pump is filled with synthetic oil that can be used in that range of
temperature.
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.

3. Operation
a. 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 containing the product (see
figure 1). Then it is possible to inject neutral gas from the nozzles, gas flushing
extended product shelf life and also act as a cushion for delicate product. 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 5 cm (2") past the seal bars. The
product should be centered in height in relation to the seal bar by adjusting the
spacers provided (see figure 1).
To obtain a good seal, make sure that no residue of fat is left between the bag's
inner sides where sealing is done.

8
b. Gas flushing (option)
There is an atmospheric pressure of 1 kg/cm2 (14 PSI) 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 neutral gas.
For gas flushing, the bags are placed on the sealing bars, the open ends placed
over the gas nozzles mounted alongside the sealing bar. After evacuation, the
vacuum valve closes and the gas valve opens. Gas quantity (%) can be set in the
program.
The necessary gas tank and pressure regulator mounted on tank is not supplied,
The pressure of the gas regulator should be set at approximately 1/3 kg/cm2 ( 5
PSI ). Each machine has an adaptor for gas connection when gas flush option is
ordered.
c. Electrical bag cut (option)
This option is used to obtain a package that the excess bagtail is cut off close to
the seal.
d. Pressure regulator (option)
This option is used to obtain more sealing pressure between the sealing bar jaw.
Suggested option for low vacuum level packaging or high level gas flushing. Also
recommended for hard to seal laminated bags. Each machine has an adaptor for
compressed air connection when pressure regulator option is ordered.
Recommend pressure regulator adjustment is 1 kg/cm2 (14 PSI), maximum setting
1.3 kg/cm2 (20 PSI),

5. Daily 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. The 350/350D is made to be
clean by hand with a damp cloth, no water can be apply directly on the machine.
Cleaning instructions for gas injection nozzles (option): 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.

15
6. Troubleshooting
a. Failure during packaging cycle
COVER DOWN ERROR’’ message is display on LCD. The input signal of the
down position switch has been lost during cycle execution. Check limit switch
adjustment.
b. Insufficient vacuum
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. Use bone-guard or thicker film for pin-hole leak
caused by sharp edge of the product (bone, etc.). Tear in bag by careless
handling can also be the source of the problem (sharp edge on filling table,
damage made by retailer or customer).
If no leak in the bag can be found, make sure you use a bag of the appropriate
size. Vacuum setting may also be too low. Check vacuum sensor with a remote
vacuum sensor. Sealing bar can also be jammed or sealing valve is not working
properly, see with service center. Vacuum pump may also need a check-up.
c. Faulty seal
Insufficient seal problem can be related to damaged Teflon or silicone rubber. Can
also be from a low sealing pressure, a leaking bellow or the sealing bar are
jammed. If there is no seal at all, the sealing wire may be or one of the electrical
component is not working properly (wire, sealing transformer, contactor. If the
sealing bar have a permanent current, check the contactor. In a case of non-
sticking seal, check bag quality (insufficient layer of poly PE). Seal area have to be
clean of contamination like juice and fat. In that case, use filling accessory.
Warning: Do not increase sealing time more than really necessary; higher
temperature will reduce working life of teflon and silicone rubber.
WARNING: All electrical work described in this brochure
should be done by a QUALIFIED and AUTHORIZED technician.

16
d. Faulty valve
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.
If the 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 (needs to be serviced).
e. Control board failure
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.
7. Maintenance
Routine controls must be made a qualified technician, contact your local service
center.
Routine controls list:
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).

17
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). Follow Busch maintenance schedule.
Check vacuum in chamber with precision vacuumeter.
Check desiccant filter for proper color, change if necessary.
Check function of cycle with various settings of timers.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.
