7.4 Sliding Window Replacement and Manual Adjustment
The sliding window replacement is accomplished by removing the front decorative panel, control center, and window glide
assemblies. The sliding window adjustment may be required due to everyday use over the life of the cabinet. Both window
glides are adjustable by a set screw and tension screw method. When adjusting the sliding window, be sure to verify
proper micro switch operation. If the sliding window is too loose, it will not properly activate the micro switches, thus
causing potential operational malfunctions to occur. If the window counter balance experiences a fault, window function
must be verified (the sliding window retention or ability to slow the rate of fall). See Sliding Window Retention Verification
in the Inspection Report).
