5.1 Load Limits
In order to maintain proper temperature and unit performance, the air curtain in each merchandiser must remain unobstructed:
• Do not stock shelves beyond the marked load limits.
• Do not block discharge or return air grilles.
• Do not block airflow in any other way (with signs, tools, packages, etc.)
Failure to follow these precautions will lead to insufficient temperature control, spoilage of stored merchandise, and excessive
frost.
