Why is it important to load open display cases according to the manufacturer's instructions?

Loading open display cases according to the manufacturer's instructions is crucial because incorrect product placement can disrupt the air curtain that is integral to the operation of these cases. The air curtain acts as a barrier to maintain proper temperature and humidity levels inside the display case, protecting perishable goods and ensuring they remain fresh. If products are placed in a way that interferes with this air curtain, it can lead to temperature fluctuations, potential spoilage of food items, and a less efficient cooling system.

Maintaining the integrity of the air curtain ultimately contributes to the overall effectiveness of the display case, ensuring that products are stored under optimal conditions. This practice also supports food safety measures by helping prevent contamination and spoilage, which is essential in a retail environment.
