3,1,8 Press ”SET” button to enter the state of voltage selection. There are tree
grades of sealing voltage, that is, ”high”, ”middle” and ”low”. Every time
you press ”SET” button, the display will indicate one voltage grade
accordingly. The indicator will illuminate in orange color.
4. Prepare before Use
4,1 Read operation manual carefully before using machine.
4,2 According to relevant regulation, fill the vacuum pump with HFV-32 high-
speed vacuum pump oil or N32 engine oil before starting the machine.
Oil level must remain at 1/2 to 3/4 of oil site glass. DO NOT OVERFILL!
4,3 The machine should be placed flat in environment with good ventilation
free of corrosive gas and big dust.
4,4 The machine should be grounded properly for electrical safety.
4,5 After opening the buckle, the vacuum lid will open automatically and the
machine is ready for work.
4,6 Press down the vacuum lid, the motor of vacuum pump stars to work after
getting power.
5. Operation Procedure
5,1 Connect to power supply. (Close air switch).
Adjust the parameters of every function, including vaccum, sealing and
cooling. Meanwhile, select suitable sealing voltage.
Select sealing voltage and regulate sealing time. There are three grades of
voltage optional, namely, high, middle and low. The sealing time should be
adjusted from low to high gradually. The seal without melting or wrinkle is
considered best. The amplitude modulation should not be too wide to
prevent the temperature from going up too high in case the Teflon tape and
other parts may be burn out.
Vacuum time should be tested and decited according to material of
packing objekt. For packing wet or other special products, it may be
necessary to prolong the vacuum time properly after the vacuum degree
reaches –0.1Mpa in order to get the best effect. The maximum setting is
99 seconds. Please decide as request.
Lay the pouch flat in the vacuum chamber with the opening of the pouch
across the sealing bar.
