SHELF CONFIGURATION
This merchandiser is designed for four
shelves.
This illustration shows recommended
shelf depth and shelf angle for the four
locations.
It is critical to case performance that no
product, shelf or stop extend beyond the
load limit, as shown in this illustration.
This configuration supports the air
curtain and provides optimal case
performance.
Check with Hussmann engineering
before using a different configuration.
