## 7. FAQ
### 7.1 General
Q. How is a hands-free dryer different from a conventional dryer?
A. It is designed to be used without holding the handle. The body is fixed on a stand or wall-mount, and the user directs airflow using the diffuser at the end of the hose or by moving the hose freely. Because both hands stay free, it suits self-styling, pet care, drying children, and users who require accessibility support.
Q. How are V2, V2Pro, and V3 different?
A. V2 (BLDC / dual overheat protection / LED display) is the entry model. V2Pro (PMSM / triple overheat protection / numeric display / detachable hose) is the mid-to-high tier. V3 (PMSM / 3-in-1 dual-mode / four diffusers) is the flagship. Choose V3 if handheld use is required.
Q. 900 W is lower than typical dryers — is it strong enough?
A. Yes — the drying performance is fast and strong, for two main reasons.
Ceramic-coated heater with high thermal emissivity: duz heaters use a specialized CERAMICA Fine Ceramic Coating. Its far-infrared emissivity reaches 0.924, significantly higher than conventional dryers. The same 900 W therefore transfers heat far more efficiently.
Fine-grained control that matches higher-wattage dryers: duz offers fine control over both fan speed and temperature. Combining fan speed 2 with temperature level 5 delivers thermal output comparable to typical 1,500–2,000 W dryers in real use.
Note on power ratings: the 1,500–2,000 W figures advertised by conventional dryers do not indicate superior motor performance or airflow. In most cases it simply means the heating element consumes that much electricity. duz uses an efficient thermal radiation structure to deliver optimal drying performance without that waste.
### 7.2 Usage
Q. Can I adjust the hose length?
A. Yes. The hose extends from about 420 to 680 mm (480 to 680 mm with the adapter).
Q. How do I install the wall-mount?
A. Use the included wall brackets (L / R), anchors, and screws to fix it to the wall. Keep at least 1 cm of clearance around the air intake.
Q. The dryer shuts off after 30 minutes — is it broken?
A. No. All models are designed to shut off after 30 minutes of continuous use for safety. You can turn it back on immediately.
Q. Can I use it as a handheld dryer?
A. V3 (iMD-2000D) and V3 Holster (iMD-2000DH) support handheld use. V2 and V2Pro are stand / wall-mount only.
### 7.3 Cleaning and Maintenance
Q. How often should I clean the dust filter?
A. Depending on the environment, once every 2–4 weeks is recommended. Accumulated dust reduces airflow and may cause weaker heat output or overheat-protection shut-off.
Q. Can I get the body wet?
A. No. Liquid ingress voids the warranty and may cause fire or electric shock. Wipe the exterior with a dry cloth only.
Q. Can I buy the diffuser or hose separately?
A. Yes — hose, diffuser, and other accessories are available separately for all models. Contact customer service with the model name for details.
### 7.4 Safety
Q. I notice a burning smell — what should I do?
A. Stop use immediately and unplug the power cable. Check for dust or foreign objects in the air intake and hose. If the symptom persists, contact customer service.
Q. The motor sounds unusual.
A. Some change in noise across fan speeds is normal. However, unexpected body vibration, metallic friction sounds, or black particles being expelled require immediate shutdown and a service request.
### 7.5 Warranty and Service
Q. How long is the warranty?
A. One year from the purchase date for all models. Proof of purchase (receipt or order number) is required.
Q. Can I repair the dryer after the warranty period?
A. Yes. Paid repair is available; parts + labor + round-trip shipping fees apply. The service technician will provide the cost after inspection.
Q. When is free repair not available?
A. User-caused damage (drops or impact, liquid ingress, unauthorized disassembly, foreign objects in the air intake, etc.) is excluded. The decision is made after inspection based on company policy.
