The Hunter Ultrasonic Humidifier, model QLS-05, is designed to add moisture to the air, improving comfort in residential settings. This owner's manual provides comprehensive instructions for its safe operation, maintenance, and troubleshooting.
Function Description:
The QLS-05 is an ultrasonic humidifier that uses high-frequency vibrations to convert water into a fine mist, which is then dispersed into the air. This process helps to alleviate dry air conditions, which can be beneficial for health and comfort, especially during dry seasons or in heated environments. The humidifier is designed for ease of use and features an adjustable humidity output.
Important Safety Instructions:
Before operating the humidifier, it is crucial to read and adhere to all safety instructions to prevent electrical shock, injury, or damage to the unit.
- Placement: Always place the humidifier on a firm, level, and water-resistant surface, at least six inches away from walls, heat sources, and electrical appliances. It should also be placed out of the reach of children.
- Cord Inspection: Before each use, inspect the power cord for any signs of damage. Do not use the product if the cord is damaged.
- Polarized Plug: The humidifier is equipped with a polarized plug (one blade wider than the other) as a safety feature. This plug will fit into a polarized outlet only one way. If it doesn't fit, reverse the plug. Do not attempt to defeat or override this safety feature.
- Unplugging: Always unplug and empty the humidifier when it is not in operation or during cleaning.
- Water Type: Use only clean, cool tap water when filling the water tank. Never use hot water or add medication of any type to the water tank.
- Operation Environment: Never leave the unit unattended in a closed room, as this can lead to excessive condensation on walls and furniture. Always leave a door partially open.
- Water Spout: Do not add water directly into the humidity spout.
- Handling: Unplug the unit before filling or cleaning. Do not remove the funnel while the unit is turned on. Do not handle the plug with wet hands.
- Mist Direction: Avoid pointing the humidity directly at electrical objects. Do not directly inhale the humidity coming from the unit.
- Cleaning Agents: Do not clean the unit with detergents or chemicals. Use only vinegar and water as directed.
- Supervision: This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning its use by a person responsible for their safety.
