Load Limit Profile

Air flow between the shelves, from the 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.
