Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

Dryers:
Dryer with stands The red filters which are positioned near the tonearm have an automatic drainage system. There will be some leakage when the air pressure builds up in the system for the first time. When the pressure in the reservoir shows 1-2 bars (20-30 psi), lift the red filters out of the stands and you will hear a slight noise due to the leakage of air. At the bottom of the filters are two black plastic outlets for drainage. Just close them with fingers for about 20 � 30 seconds and then quickly remove fingers. This will seal the drainage system and there should be no further leaking noises. Put them back into stands . The pressure should now build up to about 8 bars (120 psi) when the system will switch off automatically. It will be switched on automatically when the pressure drops to around 6 bars (90 psi). On the tonearm remove the security wire which has restricted movement of the arm bearing during transport. The tonearm is not balanced, as there is no extra weight on the headshell. When the air bearing is functioning, the counterweight will rotate the tube so that the headshell will go up. To avoid this, mount the cartridge in the headshell with stylus guard on. Open the valve. Pressure on the small pressure guage on the tonearm, should show about 4 bars. By holding the headshell and lifting it, so that the counterweight support is not touching the cueing device rod, gently move the tonearm towards the centre of the platter a few times and also rotate it up and down. If you feel any resistance do not push but check the air supply or pressure. Check wire and air supply loops to ensure that they are not crossing each other.
