Plug the model in and you’re ready to go. Self-contained refrigerated models include an onboard condensate pan for defrost water and a pre-set controller for defrost cycles. Refer to our start up video on our Resources page or click the link https://youtu.be/wfZttF_eMW4

Self-contained refrigerated models require monthly cleaning of the condenser coil. Refer to the model’s operating manual for details.

All product dimensions, including utility connection details, are located on each model’s product and technical specification sheets. Refer to a model’s product page for direct links to these documents.

All Structural Concepts self-contained refrigerated models must have barrier free air intake and discharge. Refer to each model’s product specification sheet for details on the necessary air flow.

Refrigerated and heated merchandisers must be placed in an environment with proper air ventilation. Consider the 5/10/15 rule when determining where to place equipment. Stay 5’ away from an exterior window, 10’ away from HVAC vents and 15’ away from an exterior door. Refer to additional details in our Design Guides.

The air thermometers are reading discharge air. Temperature right off the evaporator coil. There is also a defrost probe mounted on the bottom u-bend of the evaporator coil.

The controller is pre-set from the factory to the proper settings. It is password protected to help maintain the proper settings. If you have any further questions, contact tech support for further assistance.

Yes, ALL product needs to be pre-chilled before getting loaded into the equipment. Any room temperature product will add an extra heat load that can cause the unit to struggle to operate and potentially generate excess water.

No, the fans will stay running to keep constant circulation of air.

There will be an application setting sticker near the controller that will list the settings the controller will need to get programed at to hold proper product temperature.

This Serial label will be found on the equipment on a silver 3x5 foil tag. This tag will be inside the unit by the top light, on the base panel near the main power switch, or on the rear base tub.

Warm air coming in from outside of the refrigerator will lead to condensation when it comes in contact with a surface below the dew point. The equipment will be either a Type I (75degrees/55% humidity) or Type II (80 degrees/55% humidity). This ambient condition will be the max condition for the unit to be able to sustain. When outside that range, heat load onto the unit, or the lack of pre-chilled product can result in excess condensation that the equipment cannot keep up with.

The AIM Act (American Innovation and Manufacturing), enacted on December 27, 2020, authorizes the U.S. Environmental Protection Agency (EPA) to address hydrofluorocarbons in three main ways: 1) phasing down their production and consumption, 2) promulgating certain regulations for purposes of maximizing reclamation and minimizing releases of HFCs from equipment and ensuring the safety of technicians and consumers and 3) facilitating the transition to next-generation technologies through sector-based restrictions. The EPA’s final rule in the Technology Transition Program focuses on the third area—the transition to substitutes through sector-based restrictions. The final rule, signed October 5, 2023, restricts the use of higher GWP HFCs in new aerosol, foam, and refrigeration, air conditioning and heat pump products and equipment. In most subsectors, the EPA has set a maximum GWP limit on HFCs or HFC blends that can be used. The rule operates by: • Prohibiting the manufacture and import of products that use higher GWP HFCs • Prohibiting the sale, distribution and export of those products three years after the manufacture and import restriction, and • Prohibiting the installation of new heat pump systems that use higher GWP HFCs. Compliance dates and GWP limits vary based on sector (refer to full final rule). For self-contained refrigeration for the retail food subsector, the manufacture and import compliance date is January 1, 2025.

R290 is a hydrocarbon refrigerant consisting of propane, with a chemical formula of C3H8. It belongs to the category of natural refrigerants, which are substances that occur naturally in the environment and have minimal impact on global warming and ozone depletion. R290 has gained popularity as an alternative to synthetic refrigerants due to its excellent thermodynamic properties and low environmental impact.

Commercial Refrigeration: R290 is commonly used in commercial refrigeration systems, including supermarket refrigerators, display cases, and cold storage facilities. Its efficient cooling properties make it suitable for maintaining optimal temperature conditions for food preservation.

Environmental Sustainability: By choosing R290 refrigerant, businesses and consumers can significantly reduce their carbon footprint and contribute to environmental conservation efforts. Its low GWP and ozone-friendly properties align with global initiatives to combat climate change and preserve the ozone layer. Energy Efficiency: R290’s superior thermodynamic properties translate to enhanced energy efficiency in refrigeration and air conditioning systems. By maximizing cooling performance while minimizing energy consumption, R290 helps lower operating costs and promote sustainable practices. Regulatory Compliance: With stringent regulations governing the use of synthetic refrigerants, R290 offers a compliant alternative for businesses seeking to adhere to environmental standards. Its natural composition and eco-friendly credentials make it an attractive choice for industries striving for sustainability.
