Refer to "Removing/Changing the Filters" section for proper installation. • Ensure the air purifier is plugged into a working electrical outlet and the Power Knob is turned to the OFF position. • Allow the unit to operate for a few seconds at turbo speed, then leave the control knob in the turbo position for faster, more powerful room cleaning, or move the knob to the sleep setting for quieter operation. It is recommended you run your air purifier 24 hours a day to ensure continuous cleaning. Portable air purifiers are more effective in rooms where all doors and windows are closed. (SLEEP) (DAY) (TURBO) O (OFF) Filter Maintenance Calendar: Model 10590, 50100 Series The air purifier model 10590, 50100 series is equipped with a Filter Maintenance Calendar wheel which serves as a convenient reminder for you to check and replace the pre-filter and clean the HEPA filter based on the air purifier's hours of use. Upon starting your air purifier and upon every pre-filter replacement, roll the pre-filter change calendar ahead three months to indicate when the next filter replacement is necessary. Upon starting your air purifier and upon every HEPA filter cleaning, roll the HEPA filter calendar ahead 6 to 9 months (depending upon use) to indicate when cleaning the HEPA filter is necessary. Intelli-Check™ Filter Indicator: Models 50150, 50200, 50250, 50300 Series The Intelli-Check™ Filter Indicators serve as a convenient guideline for when to clean the LifeTime HEPA™ Permanent Filter and when to replace the carbon pre-filter. Depending upon your individual usage (environment and hours used), you may need to clean/replace the filters more or less frequently. When the HEPA Filter Indicator Light turns on, it's time to clean your HEPA filter. The Intelli-Check™ reminder for when to clean the HEPA filter is intended as a guideline only as the performance of the filter media is dependent on the concentration of the contaminants to which the system is exposed. If there are sources of large amounts of contaminant generation (such as dust from woodworking or heavy smoking) the HEPA filter in your air purifier may need to be cleaned more often. For instructions on how to clean your HEPA filter, refer to section "Cleaning the LifeTime HEPA™ Permanent Filter" in this manual. 4
