Load Limit Profile
Air flow between the shelves, from the Center Air Discharge (CAD) to the return, must be
maintained at all times for optimum operating efficiency and to prolong product shelf life.
At no time should merchandisers be stocked beyond the load limits indicated.
Cases may not function properly if they are loaded above load limits.
NSF®Certification
This merchandiser is manufactured to meet ANSI/NSF
®
(National Sanitation
Foundation) Standard #7 requirements for construction, materials & cleanability.
