13. Finishing Touches: Removing Wrinkles and Dents from Screens
During the installation process it is common for screen to “dent” or “wrinkle” from the pressures and
stresses of assembling. Examples of “denting” and “wrinkling” in the screens are circled in the
Figure 13A .
They are often most visible in bright, reflective sunlight. Removing (or greatly minimizing) these dents and
wrinkles is one of the final steps in the installation process. When removing wrinkles, work from the
top down.
1. Using all proper safety equipment and precautions, crew members should loosen the nuts on the
nearest columns one at a time until the “dent/wrinkle” literally “pops” out. Then, the nut(s) can
be re-tightened.
In Figure 13A , the columns in which the nuts should be loosened are between the arrow marks.
2. On occasion, it may be necessary to loosen the nuts connecting modules together. If this is the case,
ALWAYS re-tighten with impact when “wrinkle/dent” has “popped” out.
NOTE: In Figure 13A , the circles area highlights the wrinkle or dent in the dryer screen. The arrows
indicate the seams on which the nuts/bolts should be loosened to “pop” it out.
NOTE: New dryers ship with corrugated sheets.
