Pulling vacuum and vacuum treatment
1. Prepare the Item for treatment: Before beginning the procedure,
prepare the item by stabilizing it or removing any excess moisture,
dust, or debris.
2. Place the Item in the Chamber: Put the item to be treated in the
vacuum chamber, ensuring that it is positioned in the center and
doesn't touch the sides or lid. It is recommended to place a silicone
mat at the bottom when degassing to prevent pouring liquid from
spilling.
3. Seal the Chamber: Make sure that the lid is properly aligned with the
vacuum chamber and that the gasket is clean and free from debris.
4. Start the Vacuum Pump: Turn on the vacuum pump and set the
desired vacuum pressure based on your requirements.
5. Monitor the Vacuum Pressure: Keep an eye on the vacuum pressure
throughout the process. If it drops, check for leaks in the chamber or
hoses.
6. Stop the Vacuum Pump: When the stabilization process is complete,
turn off the vacuum pump. Wait for the vacuum pressure to return to
atmospheric pressure before opening the chamber.
7. If multiple cycles of vacuuming are needed, slowly open the inlet valve
to let the chamber return to atmospheric pressure, then close the valve
and repeat the process.
8. Remove the Item: After the vacuum pressure returns to atmospheric
pressure, carefully remove the item from the vacuum chamber.
9. Disconnect the Vacuum Pump: Disconnect the vacuum pump from the
chamber and hoses and properly store the equipment as per the
instructions provided in the user manual.
10. Clean the Chamber: After use, thoroughly clean the vacuum chamber
and hoses to ensure that they are free from debris and moisture.
Attention:
1. When placing the tempered glass lid, ensure that it is positioned
correctly without any deflection. If the lid is slightly inclined, the
vacuum chamber may not hold a vacuum, and the lid may be

- 11 -
sucked into the chamber with pressure.
2. If the pointer of the vacuum gauge is not in the null position or
cannot pull the vacuum to the maximum, open the black cover on
the gauge top and calibrate the pointer to normal.
3. After vacuuming, slowly turn on the outlet valve to prevent
damage to the vacuum gauge.
MAINTENANCE OF VACUUM PUMPE
Proper maintenance of the vacuum pump is essential to ensure its optimal
performance. Here are some maintenance guidelines:
Keep the pump clean and free from foreign matter.
Keep the oil filled to the oil level, and never let the pump run without
oil.
Keep the oil clean. If the oil becomes dirty, muddy, or water or other
volatile substances get in, it will affect the performance of the pump,
and the oil should be replaced. To replace the oil, start the pump and
run it for about 30 minutes to make the oil thin. Then stop the pump
and drain the oil from the oil drain plug. Open the gas inlet and run the
pump for 1-2 minutes while adding a small quantity of clean oil to the
gas inlet. This is to replace the residual oil from the inside of the pump.
After ensuring that the pump is clean, put the drain plug back in and fill
the clean pump oil from the gas inlet to the oil level.
To store the pump when not in use for long periods of time, cover the
oil cap and exhaust cap (if applicable) and store it in a dry place.
Repair of the pump should only be done by a qualified service
technician.
