After installation, prepare the unit for operation.
CAUTION! Do not block the mist outlet. Keep out of reach of children. Always place on a dry, level surface.
Primary control is the rotary knob on the front of the base unit.
Control Knob Positions:
OFF: Unit is powered off.
LOW: Produces a lower mist output for quieter operation and extended run time.
HIGH: Produces maximum mist output for rapid humidification.
Operation Tips:
- For best results, use in a closed room.
- Ideal humidity level is between 40% and 60%.
- If visible mist settles as moisture on surfaces, reduce the output setting.
- The automatic shut-off will activate when the water tank is empty. Refill to resume operation.
Regular cleaning prevents mineral buildup and microbial growth. Unplug the unit before any maintenance.
WARNING! Never immerse the base unit, motor, or electrical parts in water. Do not use abrasive cleaners or brushes.
The wicking filter should be replaced every 1-2 months, or more frequently in hard water areas or with continuous use.
Note: Using a non-genuine or worn-out filter can reduce performance and moisture output.
Automatic Shut-Off: Turns the unit off when the water tank is empty or improperly seated to prevent motor damage.
Tip-Over Protection: Some models may include a feature to shut off if the unit is knocked over.
Cool Mist Operation: No hot water or steam, reducing burn risk.
Always follow safety instructions: Use on a stable surface, keep away from children, and only use as intended.
When not in use for an extended period, prepare the humidifier for storage.
CAUTION! Never store with water in the tank. Always clean before storage.
