OVERVIEW / TECHNICAL INFORMATION / WARNINGS
OVERVIEW
These Structural Concepts Oasis® self-service cases are designed to merchandise packaged
products at varying temperatures:
5°C / 41°F or less product temperature for refrigerated produce and pre-packaged product .
3°C / 38°F or less product temperature for refrigerated red meat product.
71°C / 160°F product temperature for heated product.
These cases should be installed and operated according to this operating manual’s instructions to
insure proper performance. Improper use will void warranty.
This unit is designed for the display of products in ambient store conditions where temperatures and
humidity are maintained within a specific range.
For NSF® Type 1 Conditions (most cases): ambient conditions are to be at 55% max. humidity / 75°F.
For NSF® Type 2 Conditions: ambient conditions are to be at 60% maximum humidity / 80°F.
If unsure if unit is NSF® Type 1 or 2, see tag next to serial label. See SERIAL LABEL LOCATION &
