4. Setup

4.1 Initial Oil Filling (Before First Use)

Before using the machine for the first time, it is essential to add vacuum pump oil to the vacuum pump. This step is crucial for the machine's proper function and longevity.

1. Open the Rear Panel: Carefully unscrew and remove the screws on the rear panel of the machine to access the internal components, including the vacuum pump.
2. Locate the Vacuum Pump: Identify the vacuum pump unit inside the machine. It typically has a cap for oil filling and a sight glass or oil window to check the oil level.
3. Add Vacuum Oil: Unscrew the oil cap. Slowly inject vacuum pump oil into the pump until the oil level reaches approximately half of the display on the oil window. Any standard type of vacuum oil is suitable.
4. Secure Panel: Replace the oil cap and reattach the rear panel securely.

4.2 Power Connection

Connect the power cord to the machine's power inlet and then to a suitable AC110V power outlet. Ensure the power switch on the rear of the machine is in the OFF position before connecting.

5. Operating Instructions

5.1 Control Panel Overview

Figure 5.1: Control Panel.

The control panel features a vacuum meter, a digital display for setting and monitoring time, and buttons for controlling the vacuum, sealing, and cooling processes.

5.2 Setting Parameters

The machine allows you to adjust vacuuming time, sealing time, and cooling time. These settings should be adjusted based on the specific bag material and contents.

1. Set Vacuuming Time: Press the "Setting" button to cycle through the parameters. Use the "Raise" and "Lower" buttons to adjust the vacuuming time. A typical initial setting is 30 seconds.
2. Set Sealing Time: Press "Setting" again to select sealing time. Adjust using "Raise" and "Lower". A common initial setting is 2 seconds. For thicker vacuum bags, increase this time.
3. Set Cooling Time: Press "Setting" once more to select cooling time. Adjust using "Raise" and "Lower". A typical initial setting is 2 seconds.
4. Confirm Settings: Press the "Setting" button until the display returns to the operational state (often indicated by "ED" or similar).

This diagram illustrates the sequence for adjusting the vacuum, sealing, and cooling times using the control panel buttons. It also emphasizes the manual pressing of the cover during operation.

5.3 Vacuum Sealing Process

1. Prepare Items: Place the items to be vacuum-sealed inside a suitable vacuum bag. Ensure the open end of the bag is clean and flat.
2. Position Bag: Place the open end of the vacuum bag over the sealing bar within the vacuum chamber. Ensure the bag is flat and free of wrinkles.
3. Close and Press Cover: Close the plexiglass cover. Manually press down firmly on the vacuum cover to initiate the vacuum process. Continue pressing until the vacuum table is running.
4. Start Operation: Press the "Start" button. The machine will begin the vacuuming cycle.
5. Monitor Vacuum: Observe the vacuum meter. When the needle reaches the green area (typically 0.06-0.08Mpa), the vacuum process is complete.
6. Automatic Release: After the sealing and cooling cycles are finished, the lid will automatically pop open, indicating the completion of the operation.

5.4 Important Considerations

Figure 5.3: Operational Cautions.

This image highlights critical operational notes, specifically the necessity of firmly pressing the vacuum cover and the potential issues arising from incorrect sealing time settings, such as sparks on the heating wire.

• Pressing and holding the vacuum cover is critical for a good vacuum seal. Insufficient pressure can affect the vacuum quality and may cause sparks on the heating wire.
• Do not confuse the time settings for vacuuming and sealing. Setting the sealing time too long can also lead to sparks on both sides of the heating wire.

6. Maintenance

6.1 Cleaning

• Always unplug the machine before cleaning.
• Wipe the exterior of the machine with a damp cloth. Do not use abrasive cleaners or immerse the machine in water.
• Clean the vacuum chamber and sealing bar regularly to ensure optimal performance and hygiene.

6.2 Vacuum Pump Oil Check and Replacement

• Regularly check the vacuum pump oil level through the oil window.
• If the oil level is low or the oil appears discolored, replace it with appropriate vacuum pump oil. Refer to section 4.1 for oil filling instructions.

6.3 Heating Wire Replacement

The machine features a nickel complex alloy heating wire designed for a long working life. If the sealing performance degrades, the heating wire may need replacement. This process is designed to be easy and quick.

Figure 6.1: Sealing Bar and Heating Wire.

This image shows the robust sealing bar and heating wire, which are crucial for creating strong, airtight seals.

Consult the manufacturer's guidelines or a qualified technician for detailed instructions on replacing the heating wire.
