1. Important Safety Information
Please read all instructions carefully before using the Goyappin HC 3800 PRO-1 Steam Cleaner. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- High Temperature Steam: The steam cleaner produces high-temperature steam (up to 221°F / 105°C). Avoid direct contact with skin or eyes to prevent burns. Always wear heat-resistant gloves when handling hot components or accessories.
- Electrical Safety: Ensure the power outlet voltage matches the cleaner's requirements (110 Volts). Do not operate the appliance with a damaged cord or plug. Keep the power cord away from heated surfaces.
- Water Tank: Only use clean tap water. Do not add any cleaning solutions, perfumes, or corrosive chemicals to the water tank, as this can damage the unit and void the warranty.
- Children and Pets: Keep the appliance out of reach of children and pets. Do not allow them near the operating steam cleaner. The chemical-free cleaning process is safe for environments with children and pets, but direct exposure to steam is hazardous.
- Storage: Always unplug the appliance and allow it to cool completely before storing. Drain any remaining water from the tank.
