Champion UH-200B dishwasher is an under counter model with a built in booster for a sanitizing rinse. Whisper quiet operation makes this machine suitable for every application. The wash cycle takes 90 seconds per rack, allowing 30 racks to be processed per hour. The wash cycle can be extended for heavily soiled ware. Each rack uses only 1.1 gallons of water. In addition, an extended wash feature gives you the choice of a continuous wash mode for those tough washing jobs. The interior rinse-down cycle at shutdown aids in eliminating food particles, chemical residue and other deposits that may adhere to interior walls. This automatic feature helps save labor and improves results. Single phase operation means this machine is easy to install in every application. Hot water booster is not included with this unit.
