1. Product Description
1.1 Usage and Application
HVC series vacuum packaging machine possesses the advantages of superior function, easy
operation, simple maintenance, wide application etc. It applies to the soft packing material such as
composite film or aluminum-plastic composite film and so on. It can pack grain, food, fruit, seed,
medicine, chemical product, electronic product, precision instrument and meter, rare expensive
metal solid etc in liquid, powder or paste shape. The products after packing can be prevented from
oxidization, mildew, moth, rot and damp, so quality and freshness is guaranteed to prolong the
food’s storage period.
1.2 Product Features
The machine possesses oil-mist removing function, so it unnecessary to connect a pipe for
exhaust.
It is easy to operate this machine. The whole procedure, including lowering the synthetic glass
vacuum lid, vacumizing, gas-filling (if any), heat-sealing, label printing, cooling, air intake and
lifting the vacuum lid, is completed automatically.
The wide range of the temperature of sealing mouth can be applied to the packing bags with
different materials and thickness
There is an emergent stop switch in the control panel. If any exception in the extracting
process, press STOP can interrupt the packing procedure and return to standby state.
1.3 Operating Principle
Put the bags in the vacuum chamber and lower the vacuum lid. Startup the machine, the vacuum
pump runs and will form a vacuum space between the vacuum lid and the vacuum chamber.When
the vacuumizing finished, fill the gas to the vacuum chamber if it is needed. Then the airbag or the
cylinder will force the heating block to lift to hold down the bags in the effect of the pressure
difference inside the vacuum chamber and the outside. The flat heating wire in the heating plate
will become hot and the seal the bag when it is connected with low-voltage heavy current.
Consequently, fill the vacuum chamber with air after cooling down. The whole vacuum packing is
completed

2. Security
2.1 Preparation
This instruction is a detailed description of the carrying, storage, installation, startup, working
condition, maintenance, troubles and repairing.
It is recommended that the machine be installed by trained professional worker.
Please do abide the maintenance instruction.
Please read carefully and understand thoroughly this instruction before the use of the
machine.
Any problem please contact the supplier.
2.2 Notice for Security
Please check the power voltage and the frequency in case of error. No matter three phases
(AC380V/50Hz) or single phase, the yellow-green wire is the protective grounding wire.
Please don’t remove.
Power cord should be placed without pressure or drag and it should be put away when it is
not used.
Don’t’ operate this machine in a corrosive or dusty environment.
Don’t replace the components at will.
Keep the machine clean and remove timely the attached dust in the vacuum chamber.
Cut off the power when the machine is not used.
Please replace the vacuum pump oil timely.
Please keep this manual well for reference.
This machine is produced as per the latest technology and security standard. There maybe
danger or damage under improper operation. Please notice the keywords “DANGEROUS”,
“WARNING”, “TAKE CARE”.
E.g.:
DANGEROUS!

2.3 Operating Environment
The design of this product is running under normal temperature indoor. If the environment is in bad
condition, such as corrosive atmosphere or temperature over 35℃or less than 5℃,please
contact the manufacturer or the supplier.
The vacuum pump oil can be separated in maximum extent during its running, but not totally
separated.
TAKE CARE! UNHEALTHY!
There is residual oil of the exhaust from the vacuum pump. Breathe this gas
for long time is not good for health. This product should be placed in a
ventilating room.
Please choose the special vacuum pump oil if this machine is used for food industry.

Make sure the Power meet the requirement. (see the name plate in the machine)
Make sure the machine stands stably. Use foot plate to fix the machine after it is moved to a
suitable position. The caster should leave the ground if there is any.
Make sure the machine is laid in a horizontal position, which is one of the essential of
trouble-free operation of the machine.
4.3 Filling Oil
TAKE CARE! DAMAGE!
There is no vacuum pump oil in the newly delivered machine. The vacuum
pump works without oil will damage the pump, even in a short time.
Please make sure the vacuum pump has filled with the oil before startup.
Note: The vacuum pump should be transported without oil。
TAKE CARE! DAMAGE!
Filling the oil to the vacuum pump through other position of the pump may
damage the vacuum pump. The oil should be filled through the oil filler
hole.
TAKE CARE! SCALD!
The oil tank is full with high-temperature and high-press oil mist. The user
may get scald by the hot oil mist if the oil filler hole is open. Only when
the oil filler plug is unscrewed can the vacuum pump stop running. Please
screw the oil filler plug when the vacuum pump is working.
Unload the back cover.
Unscrew the oil filler plug with wrench in right size.
Fill the machine with appropriate special oil for vacuum pump. Please refer to the Chapter 7.3
Special Oil for Vacuum Pump.
Make sure the oil level is between 1/2 and 3/4 of the oil level indicator.
Make sure the sealing ring is installed in the oil filler plug. Replace the ring when needed.
Screw the oil filler plug.
Wait for several minutes.
Check whether the oil level is between 1/2 and 3/4 of the oil level indicator. If it is less than 1/2,
please add more.
If the oil level is between 1/2 and 3/4 of the oil level indicator, fix the back cover.
