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.

Portabletwo faucet connections
If you have two separate water inlet hoses and a drain hose, your washer can be connected to both hot and cold water faucets. Connecting the washer: l Connect the hot and cold water inlet hoses to the hot and cold faucets. l Secure the drain hose to the sink or standpipe. l Plug the power cord into a 3-prong grounded outlet. To disconnect the washer: l Turn water faucets off. l Unplug power cord and return it to storage area. l Disconnect the drain water supply hoses. Hang them on the storage rack.
Permanent installation
This washer can be converted from portable to permanent. Instructions for permanent installation come with the washer. You will need two fill hoses, one drain hose and four leveling legs. These can be purchased from your Whirlpool Dealer (Kit #285418).
