2. Safety Information

• High Temperature Warning: The sealing area operates at high temperatures. Avoid direct contact with the heating elements during operation and immediately after use to prevent burns.
• Pinching Hazard: Keep hands clear of moving parts, especially the sealing rollers, to prevent pinching injuries.
• Power Off Before Maintenance: Always power off the machine and unplug it from the power source before performing any maintenance, cleaning, or part replacement. Allow at least 30 minutes for the machine to cool down completely.
• Proper Bag Placement: Ensure bags are placed horizontally into the machine to avoid distorting the seal and potential operational issues.
• Concealed Gears: For safety reasons, the gears are concealed inside the casing. It is normal for the bag to rotate at the end of the transmission. Remove sealed bags by hand, but be careful not to place your fingers inside.

3. Setup

1. Unpacking: Carefully remove the heat sealing machine from its packaging. Inspect for any damage.
2. Placement: Place the machine on a stable, flat, and heat-resistant surface. Ensure adequate ventilation around the unit.
3. Power Connection: Connect the power cord to the machine and then to a suitable power outlet (110V).
4. Optional Conveyor Attachment (if applicable): If using the optional conveyor attachment, take out the fixing screws and metal plate from the side of the machine. Align the metal plate with the holes and secure it in place. Loosen the screws slightly, slide the metal plate in the forward direction to the desired position, and then tighten the screws. This attachment allows for seamless and continuous sealing of multiple bags.

4. Operating Instructions

1. Power On: Press the power button (①) on the digital temperature control panel to turn on the machine.
2. Set Temperature: Use the temperature up/down buttons (②) to adjust the sealing temperature according to your bag material and thickness. Refer to the temperature guide below for recommendations.
3. Start Heating: Press the heat button (③) to begin heating. The display will show the current temperature rising to the set point.
4. Begin Sealing: Once the desired temperature is reached, carefully feed the open end of the bag into the sealing slot. The automatic conveyor belt will pull the bag through, creating a tight and secure seal.
5. Continuous Sealing: For continuous sealing, align subsequent bags and feed them into the slot. The machine's efficient design allows for a sealing speed of 7 m/min.

6. Troubleshooting

If you encounter issues with your Phezer PRB-640, refer to the following common troubleshooting steps:

• Poor or Incomplete Seal:
  • Check the set temperature. It might be too low for the bag material. Increase the temperature gradually.
  • Ensure the bag is clean and dry in the sealing area. Moisture or debris can prevent a proper seal.
  • Inspect the sealing belt for wear or damage. Replace if necessary.
  • Verify that the bag is fed straight and horizontally into the sealing slot.
• Machine Not Heating:
  • Check if the machine is properly plugged into a working power outlet.
  • Ensure the power button is pressed and the heat function is activated.
  • If the heating tube was recently replaced, double-check all wire connections.
• Bags Not Moving Through:
  • Ensure there are no obstructions in the sealing path.
  • Check the conveyor belt for proper tension and alignment.
  • Verify that the machine is powered on and the motor is running.
• Temperature Fluctuations:
  • Ensure the machine is in a stable environment, away from drafts or extreme temperature changes.
  • If the issue persists, the temperature sensor or control panel might require inspection by a qualified technician.

If these steps do not resolve the issue, please contact customer support for further assistance.
