5. Operating Instructions
5.1. Basic Operation
- Power On: Turn on the machine using the main power switch. The Advanced Control System (ACS) display will illuminate.
- Place Product: Place the item to be vacuum packaged inside a suitable vacuum pouch. Position the open end of the pouch flat over the seal bar within the vacuum chamber. Ensure the pouch is smooth and free of wrinkles in the sealing area.
- Close Lid: Gently close the transparent lid. The machine will automatically begin the vacuum cycle.
- Vacuum Cycle: The machine will evacuate air from the chamber. The Sensor control ensures an optimal and consistent vacuum, up to 99.8%. The cycle time is typically 15-30 seconds.
- Sealing: Once the desired vacuum level is reached, the seal bar will activate, creating a strong, double-secured seal on the pouch.
- Air Inlet & Lid Open: After sealing, the chamber will be re-pressurized with soft air to protect the product and vacuum pouch. The lid will automatically open.
- Remove Product: Carefully remove the vacuum-packaged item.
5.2. Advanced Control System (ACS) and Program Memory
The ACS allows for precise control over the vacuum and sealing process. It features 20 program memory slots to store frequently used settings.
- Programming: Consult the on-screen menu via the control panel to adjust vacuum time, seal time, and soft air settings.
- Saving Programs: Once settings are optimized for a specific product, save them to one of the 20 memory slots for quick recall.
- Insert Plates: Use the provided insert plates to reduce the chamber volume for smaller products, which can lead to faster cycle times.
