PRODUCT OPERATION
3 1
DRYING CLOTHES
The dryer contains three racks with hanger
bars. The racks can be pulled out on rails to
allow for easier loading and hanging, as well as
for convenience.
To use the drying racks, pull the racks toward
you as far as they will go, hang the clothing, and
push the racks back in.
Note the wide space in the middle of each
hanging section. This space allows air to flow
around the clothing during drying. The spaces
should not be blocked, otherwise, it could have
a negative effect on the drying efficiency.
When hanging clothing to dry, keep the longer
articles, such as pants and dresses, toward the
dryer walls of the cabinet, and shorter articles,
such as shirts and sweaters, toward the middle.
This will allow the best airflow around the
clothing for optimum drying efficiency.
The racks may be folded up out of the way by
rotating the front up against the back wall.
