Installation Instructions 1. Prepare Your Grinder: Remove the original hopper and clean out all old beans and grounds. We recommend using a vacuum cleaner to ensure the grinder inlet is completely free of debris. Note: Do not use water, as it can rust the grinder burrs. 2. Insert the Outer Burr Seal: Place the seal around the outer burr and ensure the "UP" side is visible. Align the triangular tab with the wire on the outer burr and press it in until flush with the grinder inlet. 3. Insert the Lock Ring: Remove the lock ring from the hopper, align the tabs with the slots in your grinder inlet, and drop the lock ring on top of the seal. Press down firmly to fully seat the lock ring so that the flexible arms are aligned with the holes in the side of the grinder inlet. 4. Attach the Hopper: Align the hopper tabs with the locking ring slots and place the hopper into the lock ring. Press down, and twist clockwise until the "ARO Espresso" logo is at the 6 o'clock or 12 o'clock position and the grinder safety trigger engages. This may require some force as the O-ring creates a seal on the grinder inlet. You can use the aluminum arms inside of the hopper that hold the anti-popcorn baffle for better grip. To remove the hopper, simply twist it counterclockwise until it releases from the orange lock ring. Then remove the orange ring and seal. You may need to pull back the arms on the lock ring to release them. Setting your grind size to the finest setting will also assist with removing the hopper as it lowers the outer burr and relieves any pressure on the lock ring. Please send us a message if you need any assistance with installation or removal! Usage Instructions 1. Load the Beans: Weigh out your preferred dose and pour your beans into the hopper. Tip: the silicone bellows can be used for easy measurement and transfer of your beans! 2. Set the Bellows: Add the silicone bellows onto the top of the hopper. 3. Grind: Press the grinder trigger to start grinding. 4. Purge the Grinder: Once grinding is complete, pump the silicone bellows to purge the grinder. This works best while the grinder is spinning; restart the grinder if needed or adjust the grind time to ensure all beans are ground and there is extra time to purge the grinder. Don't be afraid to give it some aggressive pumps and be sure to use the palm of your hand to compress the entire bellows. 5. Enjoy: Savor the aroma and taste of the freshest cup of espresso.

What's in the Box? - Aluminum hopper with integrated anti-popcorn baffle and O-ring - Silicone bellows - Lock ring - Outer burr seal Care and Maintenance For daily maintenance, simply brush off any loose grounds and/or wipe clean with a cloth. When it's time for a more thorough cleaning, remove the bellows, hopper, lock ring, and seal from your machine. These components may be hand washed with lukewarm water and soap. Be sure to rinse well, and dry immediately. NOT dishwasher safe. Other Useful Info The single dose hopper can comfortably hold up to 60 grams of beans. If you need to grind more than this, simply reload the hopper or add more beans as they are being ground. If you have low cabinets, this hopper is the ideal solution. Without the bellows, it sits 1.75" (45mm) lower than the stock hopper making it possible to store the machine under low cabinets. See the images for more details on total height with the single dose hopper and bellows installed. Looking for a more affordable solution? We also sell a version of this single dose hopper that is made from plastic. Functionally, both the aluminum and plastic versions are identical. You can find the plastic version here: https://fusedline.etsy.com/listing/1456294540/ The lock ring is additively manufactured. Keep away from extreme heat.
