Operation

Analog Operation: Fill the reservoir with approximately 3 quarts of distilled water. Plug in the unit and allow it to preheat for 25 minutes. Load the product, then press the steam button for 2 seconds. Wait 20 seconds for steam to penetrate before repeating if necessary. Do not hold the button for more than 2 seconds to avoid flooding.

Digital Operation: Follow the same filling and preheating steps. The display will show "LO" while preheating and the actual temperature once reached (approx. 15 minutes). Use the quick select buttons (1-4) to begin a timed steaming cycle.

Programming for Digital Steamers

To customize the quick select buttons: press the "Program" button, select the button (1-4) to edit, and adjust the overall duration (minutes/seconds), steam injection rate, and steam shot length using the "+" or "-" buttons. Press "Program" again to save your settings.

Cleaning & Maintenance

Daily: Pour 1 cup of white vinegar into the tank and cycle the steamer. Rinse with 1 cup of distilled water until clear. Wipe the exterior with soapy water after the unit has cooled for 45 minutes.

Weekly: Remove the spray tube and water tank filter. Soak these components in vinegar for 15 minutes. Use a paper clip to remove any mineral deposits. Soak the generator surface with vinegar for 15 minutes, scrape off deposits, and reassemble.

Troubleshooting

If the unit overheats, a hi-limit thermostat will cut power. Allow the unit to cool for 45 minutes, remove the black cap on the rear of the unit, and press the Hi-Limit Reset Button.
