We have put this package together of everything you need to use your Amana E Series PTAC in one room while also cooling a second, adjacent room.
All required items, including the MDK01E main duct kit, EDK02B
extension duct and TDK02
terminal duct and grille kit are in this package.
This PTAC duct kit will allow you to transfer air between rooms (airflow distribution can be adjusted from 65/35 to 80/20).
