Philips IX Filter Cleaning Tip
The Philips iE33 and iU22 system’s power supplies tend to overheat if filters are not cleaned REGULARLY. Depending on the environment, this may mean monthly. There are two filters on this system; one is contained within the rear Input/ Output panel door and the other is behind a cosmetic panel on the lower area of the left side cosmetic panel (the cover is fastened by friction-fitted grommets so tools are unnecessary). Just a small layer of buildup on the side panel (power supply) filter can cause the power supplies to overheat and fail. The filters may be vacuumed or rinsed as long as they are completely dry prior to re-installation.
