5. Installation

The Xiaomi Mijia Smart Clothes Dryer 1S supports two main installation methods: direct ceiling installation and embedded ceiling installation. Professional installation is recommended.

5.1 Installation Conditions

  • Power Supply: The top of the balcony power supply should provide 220V AC power, typically reserved for lighting power lines.
  • Drying Rod Length: The maximum length of the drying rod is 2.2m. Ensure sufficient space for full extension.
  • Installation Space: Recommended space dimensions are: Length > 2.4m, Height: 2-3m, Width > 0.8m.

5.2 Embedded Installation

For embedded installation, a ceiling slot is required. The recommended slotting size is 150CM × 60CM × 12CM. The predetermined slotting size should not be smaller than these dimensions. Due to manual measurement, slight variations (1-2cm) may occur, and the actual installation effect should prevail.

Important Note: After embedded installation, ensure the telescopic drying rod is completely retracted into the ceiling to avoid interference with the extended drying rod and the ceiling, which could cause adverse effects on the product.

8. Troubleshooting

The Xiaomi Mijia Smart Clothes Dryer 1S is equipped with an eight-fold protection system to prevent common issues. If you encounter a problem, refer to the following:

  • Dryer Stops Unexpectedly: The dryer has an intelligent safety feature that stops movement if it detects an obstruction. Check for any items blocking the drying rods or the lifting mechanism. Clear the obstruction and resume operation.
  • Difficulty Lifting/Lowering: If the lifting or lowering mechanism seems strained, it might be due to an uneven load or exceeding the 35kg weight limit. Redistribute the laundry evenly and ensure the total weight is within the specified limit. The system allows for adjustment of lifting/lowering strength according to the load.
  • No Power/No Response: Check the power supply connection. If the issue persists, the built-in short-circuit, over-voltage, or power isolation protection might be active. Contact customer support.
  • Unusual Noise: While the motor is designed for quiet operation (55dB(A)), any unusual or excessive noise might indicate a problem. Ensure the load is balanced and there are no loose parts.
