Loose Display Window Glass on UC4.5 Control Panel

Distribution: Public - This bulletin is for public use. Notification to customers is necessary if they are known to have affected product.

Overview: The glass display window on the UC4.5 control panel may become loose. If the glass is loose, the glass will need to be glued in place and adhesive tape strips (provided by NORAC) should also be added. If the glass is not loose, NORAC recommends adding adhesive tape to the glass panel to prevent this issue from happening in the future.
