3. Setup Instructions

Follow these steps to prepare your Valemo VH-ST10 steam cleaner for use:

1. Open the Steam Boiler: Turn the boiler cap counter-clockwise to open.
2. Fill Water: Use the provided measuring cup to fill 200 to a maximum of 300 ml of distilled or soft water into the boiler. Using filtered or demineralized water helps prevent scale buildup and clogging.
3. Close the Boiler: Place the boiler cap back and turn it clockwise tightly until secure.
4. Accessories Configuration:
   • For extended reach, install the extension hose onto the steam outlet. Then, install the brush adaptor onto the extension hose, and attach a suitable brush for your cleaning task. All connections require a 90-degree turn to lock in place.
   • For direct use or stronger steam flow, the steamer can be used without the extension hose. Install the brush adaptor directly to the steam outlet, then attach the desired brush. Keep the unit mostly vertical or fill less water to avoid hot water spilling if tilting.

5. Start the Steamer: Plug the power cord into a 115V wall outlet. The indicator light will turn red, signifying that the unit is heating. It takes 2-4 minutes for cold water to heat up and generate pressurized steam. Once ready, the internal heater stops, and the light turns green.

4. Operating Instructions

Once the indicator light is green, your VH-ST10 is ready for use:

1. Steam Release: First, pull back the safety trigger with your index finger. Then, press down the button on the top of the handle with your thumb and hold it to maintain steam flow. This dual action prevents accidental steam release. Once steam starts, you can release the safety trigger and continue holding only the thumb button.
2. Cleaning: Direct the steam to the stained area. Hold it for a few seconds to soften the dirt or stain. For stubborn areas, use an appropriate brush attachment to scrub while steaming. Wipe the surface clean and dry with a cloth once the job is done.
3. Indicator Light Behavior: As steam flows, pressure inside the boiler drops, and the heater automatically reactivates (light turns red). When pressure is restored, the heater stops (light turns green). This cycle ensures continuous steam generation.
4. Water Depletion: When the water inside is completely vaporized, steam will stop flowing. The heater will cease working, and the light will turn green.

4.1 Application Examples

• Grout Cleaning: Use the grout brush or detailing brushes to clean tile grout.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your steam cleaner:

• Water Quality: Always use filtered or demineralized water to prevent mineral buildup (calcification) inside the boiler, which can clog the unit.
• Empty Water Tank: After each use, or when storing the unit for an extended period, empty any remaining water from the tank. This prevents stagnant water issues and mineral deposits.
• Refilling During Use: If water runs out during a cleaning session and you need to refill, wait a few seconds for the small safety post on the center of the boiler cap to drop to its normal position. You can gently press the post down. Then, follow the water filling steps (Step 1-3 in Setup). The boiler cannot be opened if the safety post is popped up.
• Cleaning Accessories: Clean all accessories after use to remove dirt and debris. Allow them to dry completely before storage.
• Storage: Store the steam cleaner and its accessories in a dry, safe place, out of reach of children.
