4. Setup
- Unpack: Carefully remove all components from the packaging.
- Placement: Place the main distiller unit on a clean, dry, stable, and heat-resistant surface, ensuring adequate ventilation around the unit.
- Collection Container: Choose either the plastic or glass collection container. Ensure the silicone base is securely attached to the bottom of the container to prevent slipping and protect surfaces. Position the collection container directly under the distiller's water outlet spout.
- First Cleaning: Before initial use, clean the interior of the distiller chamber and the collection container with warm water and a mild detergent. Rinse thoroughly.
- Filter Installation: Open the lid of the collection container. Place one activated charcoal filter into the designated filter tray or holder within the collection container's lid.
5. Operating Instructions
- Fill the Distiller: Remove the lid from the main distiller unit. Fill the stainless steel boiling chamber with tap water up to the MAX fill line. Do not overfill.
- Secure the Lid: Place the lid back onto the main distiller unit, ensuring it is properly seated.
- Position Collection Container: Ensure the chosen collection container is placed directly under the distiller's spout.
- Connect Power: Plug the power cord into the distiller and then into a grounded electrical outlet.
- Start Distillation: Press the 'RESET' button (or power button) on the front of the unit to begin the distillation process. The distiller's 900W heating element will begin to heat the water.
- Process: Water will boil, turn into steam, condense, and drip as pure distilled water into the collection container. The process is automatic and will typically shut off when the water in the boiling chamber has evaporated.
- Completion: Once the distillation cycle is complete, the unit will automatically shut off. Unplug the distiller from the power outlet.
- Cool Down: Allow the distiller to cool down for at least 30 minutes before attempting to clean or refill.

6. Maintenance and Cleaning
Regular cleaning is crucial for maintaining the performance and longevity of your distiller.
- Daily Rinse: After each use, once the unit has cooled, rinse the interior of the boiling chamber to remove any loose mineral residues.
- Deep Cleaning (Weekly/Bi-weekly): When mineral buildup (limescale) becomes visible, use the provided citric acid cleaner.
- Fill the boiling chamber with approximately 1 liter (0.25 gallons) of warm water.
- Add 1-2 tablespoons of citric acid powder to the water.
- Stir to dissolve the powder.
- Place the lid back on the distiller (without the collection container) and run a short cycle (approx. 15-30 minutes) or let it soak for several hours.
- Pour out the solution and scrub any remaining residue with a non-abrasive brush or cloth.
- Rinse the chamber thoroughly with clean water multiple times until all citric acid residue is gone.
- Collection Container Cleaning: Wash the collection container and its lid with warm, soapy water. The wide-mouth design facilitates easy cleaning.
- Charcoal Filter Replacement: Replace the activated charcoal filter every 2-3 months, or as needed, to ensure optimal water taste and purity.
