Delivery guy explained nothing at the time of delivery. Another technician came the next day and did try to explain how to clean the equipment every 2 weeks but when I asked for a manual he said they were out of them and hoped they would have them by Thursday last. Today is Monday so I called the office and was told to call back with an id number from the paper work I had received. When I tried to call back I couldnt get through so I am now into the second week and still dont have a clue how to operate or clean the equipment. Seems to me to be very poor service from Apria and I am very disappointed to say the least. My home phone is 386-492-****. My husband is Laurence M Smith and I am his wife Josephine Smith. Our address is 2302 Las Fuentes Drive Port Orange Florida. 32129. MY husbands dob is February 24th 1937. Please call me asap as I am very nervous about how to get help with this problem. Thank you. Josephine Smith
