Setup

- Assemble Handle: Attach the handle to the glass container if it is not already assembled. Ensure it is securely fastened.

Operating Instructions
- Fill Water Tank: Open the lid of the main distiller unit and fill the inner stainless steel tank with tap water. Do not overfill; ensure the water level is below the maximum fill line.
- Place Collection Container: Position the glass collection container directly under the water outlet spout of the main unit.
- Start Distillation: Locate the ON/OFF switch button on the side of the distiller. Flip the switch to the "ON" position. The distiller will begin operation, indicated by a red light.
- Automatic Shut-off: The distiller will automatically shut off once the distillation cycle is complete (approximately 4 hours for 4L) or if the unit overheats, thanks to its built-in thermostat.
- Second Distillation (Optional): If you need to perform another distillation cycle immediately, press the "RESET" button on the front of the unit after the previous cycle has completed and the unit has cooled slightly.
- Unplug: After use, always flip the ON/OFF switch to "OFF" and unplug the power cord from the wall outlet.


Maintenance & Cleaning
Regular cleaning is essential to maintain the efficiency and longevity of your water distiller.
- Cool Down: Always allow the distiller to cool down completely after each use before attempting to clean.
- Empty Residue: After distillation, a residue of impurities will remain in the bottom of the stainless steel inner tank. Carefully pour out any remaining water and loose residue.
- Clean Inner Tank: For stubborn mineral deposits or limescale, use the provided chamber cleaning powder. Add a small amount of cleaning powder to the inner tank with some water, let it soak for a few minutes, then scrub with a non-abrasive brush or cloth. Rinse thoroughly multiple times until all cleaning solution is removed. It is recommended to clean the water tank after being used twice.
- Clean Glass Container: Wash the glass collection container with warm, soapy water and rinse well.
- Replace Charcoal Sachets: Replace the activated charcoal sachet regularly, typically after every few distillation cycles, to ensure optimal water taste.
