Frequently Asked Questions
What should I do if the dehumidifier is not running?
Please check if there is a power cut, if the power supply is normal, or if the power plug is fully plugged in. If these are fine, inspect the fuse and replace it if it has blown.
Why is the dehumidification performance poor?
Poor dehumidification can be caused by a clogged filter, blocked air inlets or outlets, open doors/windows, or a refrigerant leakage. Clean the filter, clear obstructions, close all openings, or contact maintenance if a leak is suspected.
Why can't the room reach a suitable humidity level after long hours of operation?
This issue typically occurs if doors and windows are left open, a continuous vapor source exists inside the room, or the room size is too large for the machine's capacity. Make sure to seal the room, eliminate vapor sources, or select a machine with appropriate coverage.
What causes abnormal noise during operation?
Abnormal noise is usually caused by the machine not being placed on a stable, level surface, or due to a clogged air filter. Ensure the unit is placed stably and clean the filter regularly.
Is it normal to hear a flowing sound or feel hot air from the outlet?
Yes, hearing the sound of the refrigeration cycle during startup or shutdown is a completely normal physical process. Discharging hot air from the outlet is also standard operating behavior and does not indicate a fault.
Can I disassemble the machine myself to fix an unresolved issue?
No, if a malfunction cannot be recognized or resolved using the troubleshooting guide, please contact the supplier for professional maintenance. Do not attempt to disassemble and repair the machine on your own.
