Unpack and inspect all contents. Place on a stable, level, waterproof surface.
WARNING! Place humidifier on a level surface at least 12 inches away from walls and furniture. Do not place on carpets or uneven surfaces. Use clean, cool water only.
Power on the humidifier; adjust settings for desired comfort.
CAUTION! Always turn the control knob to OFF and unplug the unit before moving, cleaning, or refilling.
Primary control is the Humidistat Dial on the front of the base unit.
Dial Positions: OFF, LOW, MEDIUM, HIGH. Turning the dial clockwise increases moisture output.
Indicator Light: A blue or green light (model dependent) illuminates when the unit is plugged in and operational. It does not indicate water level.
Automatic Operation: Set the dial to desired humidity level. The unit will run until the tank is empty, then shut off automatically. Refill the tank to resume operation.
Tip: For best results, keep doors to the room closed. Use a hygrometer to monitor room humidity (ideal range is 30-50%).
Regular cleaning prevents mineral buildup and microbial growth. Clean every 1-2 weeks during use.
WARNING! Never use abrasive cleaners, bleach, or harsh chemicals. Do not immerse the motor unit/base in water.
The wicking filter should be replaced every 1-2 months during the season, or when visibly discolored or clogged.
Note: Using the humidifier without a filter or with a clogged filter can reduce performance and cause mineral dust (white dust).
Automatic Shut-Off: Turns the unit off when the water tank is empty, preventing the motor from running dry.
Tip-Over Protection: Some models include a switch that turns the unit off if it is tipped over.
Over-Humidification Prevention: The adjustable humidistat allows you to control output to prevent excessive moisture.
CAUTION! This is an electrical appliance. Keep away from children. Do not operate with a damaged cord or plug. Do not block the mist outlet.
When not in use for an extended period (e.g., summer months), prepare the unit for storage.
Tip: Do not store with water in the tank, as this can lead to mold or bacterial growth.
