This document outlines the use and care instructions for a large room allergen and odor reducing air purifier, specifically the Model No. AC9400 Series from Guardian Technologies. The device is designed to improve indoor air quality by filtering out particulate matter, allergens, and odors. It features a 3-year limited warranty and provides customer service contact information.

Function Description

The air purifier operates by drawing in room air, passing it through a multi-stage filtration system, and then releasing cleaner air back into the environment. Its primary function is to reduce allergens and odors, contributing to a healthier indoor atmosphere. The device is equipped with an Air Quality Monitor (AQM) that detects the amount of particulate matter (PM2.5) in the air and displays the air quality level. This allows the purifier to automatically adjust its fan speed based on the detected air quality, optimizing its performance. An ionizer function is also included, which can enhance the ability to remove particles and keep the air fresh. The unit is designed for use in large rooms, making it suitable for various household environments.

Usage Features

The air purifier is designed for straightforward operation with a user-friendly control panel. Before initial use, it is crucial to remove the filter from its protective bag within the filter compartment. The unit should be placed on a firm, level, and flat surface, at least one foot away from any walls or furniture to ensure proper airflow.

Key operational features include:

Power Control: The unit is turned on and off via a control button on the top panel. A safety feature prevents the unit from operating if the front panel is not properly closed.
Fan Speed Selection: Users can manually select from three fan speeds (1, 2, 3) or engage the Turbo Speed for maximum airflow and enhanced allergen control.
Timer Function: A timer allows users to set the purifier to run for a specific duration, from 1 to 12 hours. The timer can be canceled by holding the timer button for 5 seconds.
Sleep Mode: This mode dims the display lights and sets the air purifier to run at a low speed, ideal for nighttime use. Any control input will exit sleep mode.
Ionizer Function: An ozone-safe ionizer can be activated to further enhance particle removal and freshen the air. It can be toggled on or off as desired.
Auto Mode: When activated, the air purifier automatically adjusts its fan speed based on the real-time air quality detected by the AQM. The display shows "A" to indicate Auto Mode. In a dark room, the unit will automatically enter sleep mode (low fan speed, dim display) and restore to standard Auto Mode when light is detected.
Child Lock: This feature allows users to lock the control panel, preventing accidental adjustments. It is activated and deactivated by holding the child lock button for 3 seconds.
Digital Display: The control panel features a digital display that shows the PM2.5 particulate matter value and an Air Quality Monitor Indicator, which changes color (Green, Yellow, Red) to visually represent the air quality status (Good, Average, Poor, Very Poor). The display also shows the selected fan speed in Auto Mode.
Carrying Handle: For ease of movement, the air purifier is equipped with a carrying handle.

Maintenance Features

Regular maintenance is essential to ensure the air purifier operates efficiently and effectively. The device incorporates features to guide users through necessary cleaning and filter replacement.

Filter Change Indicator: The unit is equipped with a Filter Change Indicator light that flashes when it's time to replace the filter. Filters typically last approximately 6 months, depending on usage and environmental conditions. After replacing the filter, the indicator can be reset by holding the Filter Control button for approximately 8 seconds until the unit beeps and the light stops flashing.
Filter Replacement: The filter is easily accessible by removing the front panel. The filter is unlocked by rotating a lever to the left, allowing for removal and replacement. The new filter should be inserted with the closed end at the bottom and then locked into place by rotating the lever to the right. The front panel must be securely reattached for the unit to function. It is crucial to use only GENUINE Guardian Technologies replacement filters to optimize performance and maintain warranty validity. The manual explicitly states not to wash and re-use the filter.
Appliance Body Cleaning: The exterior and interior of the air purifier body should be cleaned regularly to prevent dust accumulation. This can be done by wiping with a soft, dry cloth. The air inlet and outlet should also be cleaned with a soft, dry cloth.
Pre-Filter Screen Cleaning: The pre-filter, designed to capture larger dust and debris, should be cleaned monthly or more frequently depending on use. It can be cleaned using a brush attachment or a vacuum cleaner. This helps maintain the life of the main filter.
Motor Protection Circuit: The air purifier has a motor protection circuit that will activate and shut off the power if an overload occurs. An audible "chime" and a flashing "Err" warning on the display will indicate this. To restart, the unit must be unplugged for 10 minutes and then plugged back in. If the issue persists, professional service may be required.
Cleaning Agents Caution: It is important to never immerse the appliance in water or any other liquid. Aggressive or flammable cleaning agents such as gasoline, benzene, thinner, bleach, alcohol, or other solvents should not be used on any part of the appliance, as they can damage the product.
Troubleshooting Guide: The manual includes a troubleshooting guide to help users address common issues such as the unit shutting off unexpectedly, no air circulation, increased noise, or persistent odors. Solutions often involve checking the power connection, filter installation, filter cleanliness, or turning off the ionizer.
