Thank you for purchasing the LintGard “Dryer Safety Monitor”. The LintGard utilizes proven technology to
accurately detect the back pressure in your dryer duct caused by lint build-up. Unlike other monitors that can
produce false readings, the LintGard produces exact pressure readings for optimum dryer safety & efficiency.
Please read all installation and operating instructions before use.
Dryer Safety Monitor
Helps Keep Your Dryer Working Safely & Efficiently
Dryer Fires:
The USFA (U.S. Fire Administration) found that clothes dryer fires account for about 15,600
structure fires, 15 deaths, and 400 injuries annually. “Failure to clean” is the leading factor
contributing to clothes dryer fires in residential buildings. LintGard helps to ensure home
safety and reduce energy costs by taking the guess work out of knowing when to clean
your dryer vent.
Here’s How the LintGard Works:
Over time, lint builds up in your dryer vent system causing reduced airflow and increased
back pressure. This reduced air flow results in longer drying times, higher utility costs and
an increased risk of a dryer fire.
The LintGard measures the back pressure caused by lint build up in your dryer duct. As
the pressure increases, the gage oil moves up the scale (measured in “inches of water
column”). Once the oil moves into the yellow or red zone, it’s time to clean your dryer vent.
It requires no electricity or battery power to operate so you can enjoy years of trouble free
operation while safely monitoring your dryer’s operation.
Important Notes:
Normal drying with a load of clothes in the drum and the dryer on a heat setting will lower
the back pressure and produce inaccurate readings.
For best results, be sure to check the “True Back Pressure” once a week by 1) cleaning
the lint screen, 2) select the “fluff” cycle or “air only” cycle (no heat), 3) run dryer with “no
clothes” in drum.
Works on “Dual Motor” Dryers: The vast majority of dryers utilize “single motor” technology.
However, a very small percentage of high end dryers use “dual motor” technology. The
LintGard works on all types of dryers by testing “True Back Pressure” as stated above.
