Switching the chute is for when you have a double door for a store that gets a pretty decent amount of volume, where one door is PIPO only and the other receives freight. When the one that receives freight is ready to close/or is cut, A-sort can switch which door is receiving freight. So in a perfect world, one door is shut, a-sort operator changed the chute to the door that was receiving pipo, and it should never stop the flow of freight. Triple door is very similar except two doors are receiving freight and one receives pipo, however in my DC depending on the store we don’t typically switch the chute for triple doors because they are designated pipo only doors.
