VacMaster Chamber Sealer Maintenance Guide: Keep Your Machine Running Smoothly

We’re thrilled you’ve chosen a VacMaster Chamber Vacuum Sealer! Whether you’re sealing food for freshness, prepping for sous vide, or packaging products professionally, we’re here to help you get the most out of your machine. Regular maintenance isn’t just about keeping your sealer running, it’s about ensuring every vacuum-sealing session is as smooth and reliable as the first. From oil pumps to dry pumps and even machines with gas flush capabilities, this guide will help you keep your VacMaster performing at its best. Let’s dive into how you can maximize the life and performance of your vacuum sealer! 

Understanding Your Chamber Sealer

• Oil Pumps: Ideal for high-demand environments, oil pumps run quietly, generate less heat, and operate continuously. However, they require regular oil changes every 250 cycles or three months to maintain performance.
• Dry Pumps: Maintenance-free design and perfect for home users. Dry pumps generate more heat and noise, needing cooldown periods after 8–12 cycles. Regular inspection of the lid gasket for wear is necessary to maintain a proper seal.

Gas Flush Capacity

Gas flush enhances product shelf life and appearance by replacing oxygen with gases like nitrogen to extend shelf life and protect delicate items like baked goods and pasta. This anaerobic packaging process helps prevent bacteria growth and preserves color of product. Regularly inspect gas lines and nozzles for blockages to keep this feature running smoothly. Applicable Models: VP545, VP680, VP600, VP800.

Maintaining Oil Pump Models

Routine Maintenance

Routine oil pump care is crucial for strong vacuum pressure and a long-lasting machine.

• Routine Maintenance: Change oil every 250 cycles or three months, whichever comes first. Replace filters every 3 years or earlier if contaminated.
• Signs oil needs changing: Look for dirty, milky oil, debris, or weak vacuum performance.

Oil Change Procedure

• Keeping up with oil changes ensures a healthy pump and strong vacuum pressure.
• Follow the oil change instructions in your owners manual. Refer to our oil change guide for when to change your oil.

Troubleshooting Common Issues

• Weak Vacuum: Likely due to dirty oil or a leak in the machine. Check for leaks by running a cycle without a bag and observing the gauge:
• Leak Test (not applicable on VP95):
  • Set vacuum time to 30 seconds.
  • Close the lid (no bag required) and start the cycle.
  • When the display reads "5," turn the machine off with the main power switch.
  • Observe the needle on the gauge—if it moves toward the red, there's a leak and you will need to contact customer support.
• Pump Overheating: Keep oil levels consistent for a clean operating environment.

Maintenance for Dry Pump Models

Gas flush systems are excellent for extending product freshness, but they require specific care.

Routine Maintenance

• Daily Care: Inspect the lid gasket regularly for wear or damage. Clean the chamber and seal bars after each use.
• Common Troubleshooting:

If vacuum pressure drops, perform a leak test similar to oil pump models.

For error codes like “F1,” check the lid, micro switch, or startup procedure. Most commonly the F1 code displays because the lid is in the locked position when the machine is turned on. Turn off the machine, move the locking bar forward, and lift the lid. Turn the machine on.

Gas Flush Systems: Special Maintenance Tips

Gas flush systems are excellent for extending product freshness, but they require specific care.

• Inspect gas lines and nozzles regularly for blockages.
• Perform test cycles to fine-tune gas flush settings for your product.

 Required Tools & Materials For Setup

    Dual-Stage Regulator:  

    Reduces pressure to 7–12 PSI to avoid damaging the machine.

    Must be purchased to avoid damaging equipment

    Gas Tank:

    Select size based on usage; consult your local gas supplier.

    Hoses & Clamps:

    3/8" hose and adjustable hose clamps to prevent disconnections.

Maintenance Tips

•     Inspect gas lines and nozzles regularly for blockages.
•     Perform test cycles to fine-tune gas flush settings for your product.

Troubleshooting Gas Flow Issues

• Ensure proper regulator settings.
• Check hoses for leaks or blockages.

General Maintenance for All Chamber Vacuum Sealers

Some maintenance steps apply universally across all VacMaster Chamber Sealers.

• Daily Care: Inspect the lid gasket regularly for wear or damage. Clean the chamber and seal bars after each use.
• Seal Bar Maintenance: Replace worn-out seal bars or seal bar tape and calibrate seal time to match bag materials.

Common Error Codes and Fixes

• "_ _": Machine ready to run a cycle.
• "ED": End of demonstration; ready to run a cycle.
• "F1": Cycle issue; check lid or micro switch.
  • Causes:
  • Turned the machine on with the lid closed.
  • Running a cycle with the lid latch on.
  • Lid shocks don’t open the lid all the way after a cycle is completed.
  • Bad micro switch.
• "Co": Oil change required; change oil and reset the machine by holding "set" and arrow buttons for 3 seconds.
  • Change the oil.
  • Press and hold the “set,” “up arrow,” and “down arrow” at the same time for 3 seconds.

When to Contact Tech Support

If your VacMaster Chamber Vacuum Sealer continues to have issues, it may be time to seek professional assistance:

• Persistent vacuum issues after troubleshooting.
• Leaks that cannot be resolved with a gasket replacement.
• Recurring error codes despite corrective actions.
