1. Use and Characteriscs
Use:
This vacuum packing machine possess the advantages of superior funcon, easy operaon, simple maintenance and extensive
applicaon. It applies so packing materials such as complex lm or aluminium foil complex lm. It can pack solid, liquid or
powder and paste grain, food, fruit, seed, fragrant arcle, medicine, chemical product, electronic product, precision instrument
and meter, rare expensive metal etc. in the vacuum or can ll them with inert gas under vacuum condions. The products
packed by the machine are prevented from oxidizaon, mildew, moth, rot and damp, and can guarantee quality and freshness
so as to prolong the food’s storage period.
Characteriscs:
1. This machine is easily used. From pressing the cover of the machine to draw out air, heang the sealing, prinng the
label, cooling, lling with gas and opening the cover of the machine, the whole course is automacally controlled.
2. The regulang ranges of the sealing temperature and me are very wide so that the machine is able to pack various
materials.
3. There is an emergency stop buon on the control panel. If the packed items are abnormal during drawing air, you can
press the emergency stop buon to stop the packing procedure.
2. Specicaons and technical parameters
Basic technical parameters
3. Control panel layout
The control panel should be set rst before operang the machine:
1. The lid of the device must be open in order to change the sengs.

3. Control panel layout Connued
2. .Turn on the power switch located next to the plug and the pilot lights will turn on. Press the “Vacuum” or “Sealing”
buon and the “Increase” or “Decrease” buons to change the me for drawing air and heat-sealing to corresponding
numbers (for instance: if “28” for drawing air and “15” for sealing, then the me of drawing air is 28 seconds and the
sealing me is 1.5 seconds).
3. Firmly press down the lid of the machine and once the vacuum pump starts to draw air then the lid of the machine will
seal shut automacally. The “Decrease” and “Increase” buons control the me of drawing air by regulang the degree
of the vacuum according to the packing requirement. Pressing “Increase” will increase the degree of vacuum and press-
ing “Decrease” will reduce the degree of vacuum.
4. Once air drawing has reached the set me, the course of air drawing will end.
5. Aer the compleon of air drawing, the procedure of sealing begins. There are 3 dierent heat sealing temperatures for
materials of variang thickness, low, medium, and high. Press the “Seal Temperature” seng to cycle through the
dierent temperatures, select the one that will suit your packaging thickness. Change the sealing me by pressing the
“Sealing” buon and the “Decrease” and “Increase” buons, raise the sealing me slowly in order to prevent the seal-
ing temperature from geng too high and burning the sealing parts or from melng the packaging materials.
6. Sealing ends once it is has reached the set sealing me. The atmosphere will enter into the vacuum room through the
solenoid valve, then the cover of the machine will open automacally. The whole procedure is nished, and the next
packing cycle is prepared and ready to go.
4. Before Use
Before operaon, you must be well acquainted with the operaon and use instrucons.
1. You must ll the vacuum pump with NO. 68 Food Grade Oil up to 3/4 height of the oil window before starng the ma-
chine. (It is recommended to empty and ush any old oil before adding the NO. 68) At the end of each cycle, the oil level
should not be lower than 1/2 height of the oil window. Do not ll with too much oil as to avoid the oil spraying out. The
oil pump is located behind the panel in the back of the machine.
2. The machine should be placed horizontally in good venlaon and without corrosive gas and dust.
3. Whether using three-phase four-wire or single-phase power, both should be connected with the protecve earth wire
separately for safety.
4. Before starng the machine, select the “Seal Temperature”, the sealing me, and the vacuum me to suit your require-
ments.
5. Plug the machine into power and ip the switch to “ON” and press down the cover of vacuum to start the vacuum
pump. If the temperature is low or the lubricang oil in the vacuum pump is thick, then start the vacuum packing ma-
chine several mes unl the lid of the machine is sealed. (Before starng the machine, turn o the “Seal Temperature”
seng buon to avoid damaging the sealing cloth.)
If the vacuum pump gives out a lot of noise and the vacuum gage’s pointer does not move, then the vacuum pump’s rotary
direcon is wrong—the dynamo’s fan should rotate an-clockwise and the three-phase power should change any two of the
three power terminals (single-phase power hasn’t this phenomenon).

5. Operaon procedure
1. Plug the machine into power and choose a packing bag to your requirements.
2. Regulate the heat-seal temperature and time, and choose a high or low heat-seal temperature for sealing. Select your
“Seal Temperature” and your sealing time. To prevent melting or wrinkling the packaging, and to avoid damaging the
Teflon coated fabric (sealing cloth) and other parts, start out with a low temperature and a short sealing time.
3. The vacuum drawing time should correspond to the contents in the packaging and to the value of the vacuum gage. To
get the best effect when packaging wet or special products, it is recommended that you prolong the air drawing time
after the vacuum degree reaches 0.1Mpa (the longest time is 99 seconds).
4. Place the packing bag in the vacuum chamber, the bag mouth should be placed on the heating frame flatly.
5. After finishing the above, the machine is ready to start. Press down the cover of the machine, and the machine will start
automatically.
6. The Vacuum packer will form an airtight seal and draw air for the entered in time.
7. Once the time for the air drawing has ended, the machine will seal the packaging for the entered in time. After the pack-
age is sealed, the machine will end the packaging procedure and open the lid, ready for the next item to be packaged.
6. Other maers
1. One surface of the silicone rubber strip is cross hatch plane and the other surface can be for installing parcle and
prinng label.
2. During work, press the emergency stop button if it is necessary to stop the machine urgently, then the cover of the ma-
chine will open automatically.
3. If you are not using the machine, the power (power switch outside of the machine) should be turned off.
4. The external power wire’s sectional area should be bigger than the inside wire’s sectional area.
5. If elevation above sea level is much higher in the location, than the environmental pressure will be much lower and so
the value of the vacuum pressure gage will correspond lower (see table).
