CLEANING & MAINTENANCE
ABOUT THE AIR MONITOR
The TPP640S is designed with an air monitor to
track the quality of your air. Over time the monitor
can become dirty and may require cleaning. The
main symptom of a dirty air monitor is the LED
display remains frozen on one light color. In order
to clean the air monitor you must use a vacuum to
clear the monitor chamber.

2. Locate the 3 small vent holes in the rear of the unit
just about the inlet grill.
3. Use a vacuum cleaner hose to suction any dust or
dirt that may have accumulated inside the monitor
chamber.
