CLEANING & MAINTENANCE

Cleaning 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.
1. Power off and unplug unit.
2. Locate the 3 small vent holes in the rear
of the unit just about the inlet grill. (Fig. 1)
3. Use a vacuum cleaner hose to suction any
dust or dirt that may have accumulated
inside the monitor chamber. (Fig. 2)
