This illustration shows how the duct exhaust system is to be cleaned prior to initial calibration of the LintAlert. You'll want your baseline settings to be created
when the exhaust is in a like new state so the efficiency monitoring system gives you an accurate feel for normal declines in efficiency over time.
The command module computer is designed to increase the alert intervals for more efficient exhaust systems. Correspondingly, dryer ducts that are more restrictive get assigned
shorter intervals for each alert level.
