3. Setup and Installation
Follow these steps to correctly install a new SteFik dust bag into your compatible ZELMER vacuum cleaner. Always ensure the vacuum cleaner is unplugged from the power outlet before performing any maintenance or installation.
- Power Off and Unplug: Disconnect your vacuum cleaner from the main power supply to prevent accidental activation.
- Open Vacuum Compartment: Locate and open the dust bag compartment on your ZELMER vacuum cleaner. Refer to your vacuum cleaner's specific manual for compartment access instructions.
- Remove Old Bag: Carefully remove the full dust bag. Most compatible models feature a sealing mechanism on the bag's collar to prevent dust leakage during removal. Dispose of the used bag responsibly.
- Insert New Bag: Take a new SteFik non-woven fabric dust bag. Align the blue plastic collar of the new bag with the bag holder inside the vacuum cleaner compartment. Push firmly until the bag is securely seated. Ensure the bag is fully unfolded inside the compartment without obstructing any filters or mechanisms.

4. Operating Instructions
Once the dust bag is correctly installed, your vacuum cleaner is ready for operation. The SteFik dust bags are designed for standard dry vacuuming tasks. For optimal performance:
- Operate your vacuum cleaner as per its manufacturer's instructions.
- Regularly check the dust bag indicator on your vacuum cleaner (if available).
- Replace the dust bag when it is full or when suction power noticeably decreases.
5. Maintenance
Proper maintenance of your dust bags ensures efficient vacuuming and extends the life of your appliance. SteFik dust bags are designed for single use and are not washable or reusable.
- Regular Replacement: Replace the dust bag promptly when it is full. Overfilling can reduce suction power and potentially damage your vacuum cleaner.
- Disposal: Dispose of used dust bags in accordance with local waste disposal regulations. The bag's sealing mechanism helps contain dust during disposal.
- Storage: Store unused dust bags in a cool, dry place, away from direct sunlight and moisture, to maintain their integrity.
