| NSF/ANSI 7 certification | Whether the exact model is certified or listed to the applicable edition of NSF/ANSI 7 for its intended use. | Match the model identifier on the unit and product documentation to the certifier’s current listing. Check the scope and any use limitations. | Model and listing verified: Yes / No |
| Intended application | Whether the unit is designed for the specific use, such as packaged-food display, food storage, or another stated application. | Compare the product listing, installation instructions, and manufacturer-stated use with the foods and service conditions at the site. | Application matches: Yes / No |
| Food-contact and cleanability | Whether food zones and exposed surfaces are suitable for their intended contact and can be accessed and cleaned as required. | Review the listing and service manual; inspect seams, corners, shelves, drains, and other areas where soil or moisture could collect. | Cleaning access acceptable: Yes / No |
| Temperature performance | Whether the unit maintains the temperatures stated for its certified application and operating conditions. | Review test or certification documentation and verify performance under the specified ambient conditions and loading instructions. Do not assume an empty-cabinet reading proves loaded performance. | Required operating range documented: Yes / No |
| Cold-holding operation | Whether the operating plan keeps time/temperature-controlled foods at the temperature required by the applicable food code. | For U.S. Food Code applications, cold-held time/temperature control for safety food is generally maintained at 41°F (5°C) or below, subject to applicable code provisions. Check food temperature with a suitable thermometer. | Food temperature meets local code: Yes / No |
| Temperature monitoring | Whether the display, controls, and any alarms provide useful monitoring for the intended operation. | Compare the cabinet display with a calibrated thermometer; check alarm operation and establish a routine for recording temperatures. | Monitoring method and schedule documented |
| Loading and air circulation | Whether shelves, product placement, and display layout allow the airflow required by the operating instructions. | Check for blocked supply or return-air openings and follow stated loading limits. Avoid assuming that a packed display will perform like an unloaded one. | Loading guidance available and followed: Yes / No |
| Installation conditions | Whether site conditions meet the unit’s installation requirements, including ventilation, clearances, and ambient temperature limits. | Compare the planned location with the installation manual, including required clearances and any restrictions on exposure to heat or direct sunlight. | Site requirements satisfied: Yes / No |
| Electrical safety | Whether electrical safety approval is documented separately from NSF/ANSI 7 sanitation and performance certification. | Review the equipment nameplate and applicable electrical safety documentation; confirm the supply and installation comply with local electrical requirements. | Electrical documentation checked: Yes / No |
| Maintenance and service | Whether routine cleaning, condenser care, door or gasket inspection, and service access are practical. | Review the maintenance schedule and confirm the unit can be serviced without obstructing required ventilation or food-handling areas. | Maintenance plan in place: Yes / No |
| Final purchasing decision | Whether certification, intended use, operating capacity, site conditions, and maintenance needs all match the operation. | Resolve any mismatch before purchase; obtain written clarification for model-specific certification scope or performance claims. | Suitable for this application: Yes / No |
