Narrative:
While checking an interior lavatory write-up on an inbound flight; I was approached by flight attendant who showed me an aviox oxygen (O2) unit at 2H that had the emergency use decal missing. Not knowing if unit had been used I removed unit and ordered a new [aviox] unit. Upon arrival the unit had to be unboxed and assembled completely.after reading the maintenance manual (MM) 35-30-99 I assembled the unit and reinstalled it in the aircraft. This was the first time I have had contact with one of these units. I made an entry into our non-routine maintenance computer and signed it off. The plane left the gate and I was taking care of the old aviox unit and was examining it; and realized that I had not reset the actuator pin correctly. I did not want any issues further down the line so I immediately contacted my lead and we contacted maintenance control representative; mr. 'X'; who was very helpful and we were able to straighten it out over the phone with ZZZ maintenance as to exact location top or bottom unit in the doghouse [compartment].
