VEVOR 50L/Day Commercial Dehumidifier with Drain Hose, Heavy-Duty for Basements, Crawl Spaces, Industrial Use, Auto Defrost

Q: Can I use the dehumidifier immediately after receiving it?

A: Since the unit contains a compressor, please keep it upright for at least 8 hours before plugging it in, especially if it was tilted or transported over a long distance. This helps protect the internal components.

Q: Why are there water droplets inside the machine?

A: Each unit is fully tested before leaving the factory to ensure safety and performance. If you notice residual water inside the tank or system, it's a result of quality testing — not a sign of previous use. You can use it with confidence.

Q: Is it normal if the compressor doesn’t start immediately after turning the unit on?

A: Yes. To protect the compressor from frequent starts and prolong its lifespan, the system is designed to delay compressor restart for about 3 minutes. This is a normal safety feature.

Q: How does the smart defrost function work?

A: At low temperatures, frost may form on the evaporator or condenser. When detected, the unit enters defrost mode: the compressor stops, and the fan runs to melt the frost. After defrosting, the unit resumes normal operation.

Q: Why is warm air coming out of the machine?

A: During operation, the dehumidifier pulls in humid air and releases drier air that is slightly warmer than room temperature. This is due to the internal heat exchange process and is completely normal.
