Ensure control is OFF and humidifier is properly assembled.
Plug power cord directly into wall outlet; avoid extension cords.
If using with a GFCI outlet, ensure it is functioning properly.
For storage, unplug and wrap cord around storage hooks on base.

Tip: Place humidifier near center of room for best moisture distribution. Keep away from electronics, fabrics, and direct sunlight.

Operation

Daily operation procedures for optimal performance.

Check water level: Monitor tank and refill when low water light comes on.
Adjust settings: Change HUMIDISTAT as needed for seasonal changes.
Monitor humidity: Use a separate hygrometer to verify room humidity.
Night operation: Use low setting for quiet bedroom operation.
Automatic operation: Unit cycles automatically based on humidistat setting.
When away: Turn POWER off if leaving for extended periods.

WARNING! Never add additives, oils, or chemicals to water tank. Use clean, cool tap water only. Do not operate without wick filter installed.

Maintenance & Cleaning

Daily: Check water level; refill with fresh water as needed.

Weekly: Clean tank with mild soap and water; rinse thoroughly.

Monthly: Deep clean base and tray with white vinegar solution (1 part vinegar to 3 parts water) to remove mineral deposits. Replace wick filter every 1-2 months or when visibly clogged.
