PRIMARY LINT TRAPS
The primary lint trap is located in the front
of the machine inside the lower lint trapdoor.
Figure 5-27 illustrates a laundryman cleaning the
lint trap and lower casing. Cleaning the primary
lint trap and lower casing should be done once
every 2 hours. Proper cleaning of the lint trap
eliminates airflow restrictions which increase the
time for drying each load and create possible fire
SECONDARY LINT TRAPS
Secondary lint traps help to cut down the
buildup of lint in ducting. Air that has gone
through the primary lint trap and left the dryer
still may have lint in it. This lint and debris build
up in the ducting blocking airflow. Ducts that
have long runs and elbows attract lint that gets
stuck and builds up creating back pressure and
a possible fire hazard. Inspection and cleaning of
these vents and ducts should be done monthly.
Secondary lint traps can be installed by procuring
dryer lint trap bags and installing them as
indicated in figure 5-28. Lint bags are available
