Operating Instructions
Follow these steps for daily operation of your CMA Dishmachines AH dishwasher.
- Pre-Scraping: Before loading, scrape all large food particles from dishes and utensils. This prevents clogging and ensures effective cleaning.
- Loading Racks: Load dishes into the provided racks (one open and one peg rack included). Ensure items are spaced to allow water and chemical spray to reach all surfaces. Do not overload racks.
- Closing Door: Close the dishwasher door securely. The machine features an auto "start/stop" function, which initiates the cycle upon door closure.
- Cycle Initiation: The wash cycle will automatically begin once the door is closed. The low-temperature chemical sanitizing process will run for a preset duration.
- Delimer Switch: If lime scale buildup is observed, activate the delimer switch as needed. Consult your chemical supplier for appropriate deliming agents and procedures.
- Unloading: Once the cycle is complete, open the door and carefully remove the clean, sanitized racks. Allow items to air dry if necessary.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your dishwasher.
- Daily Cleaning: At the end of each day, drain the machine, remove and clean the Poly Pro scrap accumulator, and wipe down the interior and exterior stainless steel surfaces.
- Spray Arm Inspection: Regularly inspect spray arms for clogged nozzles. Clean any blockages to ensure proper water distribution.
- Chemical Levels: Monitor chemical levels (detergent, sanitizer, rinse aid) in external dispensers and refill as needed.
- Deliming: Perform deliming procedures regularly, especially in hard water areas, to prevent mineral buildup. Use the delimer switch and appropriate chemicals.
- Gasket Inspection: Check door gaskets for wear or damage. Replace worn gaskets to prevent leaks and maintain proper sealing.
- Professional Servicing: Schedule periodic professional maintenance checks to ensure all components are functioning correctly and to address any potential issues.
