System Description
The PSIUs are installed in the passenger service supply channels. The passenger service supply channels are located on the bottom side of the overhead stowage compartments.
The PSIUs are hung from the attachment rails and held in position with the section hose. Clamping blocks are installed in different positions to stop the PSIUs move in a FWD/AFT direction. The spaces between the PSIUs are filled with blank filler panels. The filler panels have different dimensions. This is to let you position the PSIUs correctly to agree with customer seat layouts.
Each PSIU has two primary units:
The PSIUs are hung from the attachment rails and held in position with the section hose. The clamping blocks, installed in different positions, prevent the PSIUs from moving in a FWD/AFT direction. The spaces between the PSIUs are filled with blank filler panels. The filler panels have different dimensions. This will let you position the PSIUs correctly to agree with customer seat layouts.
Each PSIU has one or two parts that are installed above each seat row:
