Quick Start Guide
7. Non-Standard Paint options may cause risk from electrostatic
discharge. Avoid installations that cause electrostatic build-up on
painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special option code, contact the
manufacturer for more information.
