Narrative:

On jun/xa/01, ship arrived in ZZZ. A deferred item was on board the aircraft with the oxygen mask door not latching. A passenger service unit was ordered to fix the deferred item. The door on the broken passenger service unit was taped closed as well as row xa seats. I removed the broken passenger service unit and installed the new one, inadvertently overlooking the reference in the maintenance manual for swapping the oxygen generator. The old passenger service units parts tag was filled out and put in the shipping box and sent to stores. Because I did not change over the oxygen generator from the old passenger service unit to the new one, stores shipped the passenger service unit with the oxygen generator still attached. Callback conversation with reporter revealed the following information: the reporter stated the passenger service unit procedure did not mention the removal and installation of the oxygen generator. The reporter said the special handling procedures for the oxygen generator were in the maintenance manual in the description and operation section. The reporter said only the passenger service unit procedure was used for the work. The reporter stated the aircraft flew 6 trips with no oxygen generator in the passenger service unit. The defective passenger service unit was sent to stores without any special handling tags to alert stores of the oxygen generator canister still installed. The reporter said his job experience is several months less than a yr. The reporter stated the FAA has made contact and was interviewed.
