.Turn on the power switch located next to the plug and the pilot lights will turn on. Press the
“
Vacuum
”
or
“
Sealing
”
button and the
“
Increase
”
or
“
Decrease
”
buttons to change the time for drawing air and heat
-
sealing to corresponding
numbers (for instance: if
“28”
for drawing air and
“15”
for sealing, then the time of drawing air is 28 seconds and the
sealing time 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 automatically. The
“
Decrease
”
and
“
Increase
”
buttons control the time of drawing air by regulating 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 time, the course of air drawing will end.
5.
After the completion of air drawing, the procedure of sealing begins. There are 3 different heat sealing temperatures for
materials of variating thickness, low, medium, and high. Press the
“
Seal Temperature
”
setting to cycle through the
different temperatures, select the one that will suit your packaging thickness. Change the sealing time by pressing the
“
Sealing
”
button and the
“
Decrease
”
and
“
Increase
”
buttons, raise the sealing time slowly in order to prevent the seal-
ing temperature from getting too high and burning the sealing parts or from melting the packaging materials.
6.
Sealing ends once it is has reached the set sealing time. The atmosphere will enter into the vacuum room through the
solenoid valve, then the cover of the machine will open automatically. The whole procedure is finished, and the next
packing cycle is prepared and ready to go.
4. Before Use
Before operation, you must be well acquainted with the operation and use instructions.
1.
You must fill the vacuum pump with NO. 68 Food Grade Oil up to 3/4 height of the oil window before starting the ma-
chine. (It is recommended to empty and flush 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 fill 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 ventilation and without corrosive gas and dust.
3.
Whether using three
-
phase four
-
wire or single
-
phase power, both should be connected with the protective earth wire
separately for safety.
4.
Before starting the machine, select the
“
Seal Temperature
”,
the sealing time, and the vacuum time to suit your require-
ments.
5.
Plug the machine into power and flip the switch to
“
ON
”
and press down the cover of vacuum to start the vacuum
pump. If the temperature is low or the lubricating oil in the vacuum pump is thick, then start the vacuum packing ma-
chine several times until the lid of the machine is sealed. (Before starting the machine, turn off the
“
Seal Temperature
”
setting button 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
direction is wrong—the dynamo
’
s fan should rotate anti
-
clockwise and the three
-
phase power should change any two of the
three power terminals (single
-
phase power hasn
’
t this phenomenon).
