The CMA-180UC-3 is a commercial, single-rack, under-counter dishwasher designed for hot water sanitizing. The machine operates on a 2-minute cycle. Key requirements for operation include a 120°F minimum water supply at 24 PSI and a dedicated 208/240V electrical circuit. Daily maintenance involves cleaning the scrap screen and spray arms to ensure proper performance.
Installation Requirements
Proper installation is critical to maintain the warranty. Ensure the following conditions are met:
- Leveling: The machine must be level side-to-side and front-to-back. Use leveling feet to adjust for uneven floors.
