About the Structural Concepts NE6020RSV SC
Structural Concepts model NE6020RSV SC is a service-over-counter display case that meets ENERGY STAR efficiency requirements. The cabinet measures 20.4 in. high, 60 in. wide and 33 in. deep (52 × 152 × 84 cm).
A service-over-counter case displays deli meats, cheeses, prepared foods or bakery items behind glass, with staff serving from the rear. It offers 18 sq. ft. of display area. Defrost is automatic, so frost on the evaporator coil is cleared on a timed or demand cycle.
Rated energy consumption is 5.08 kWh per day — about 1,854 kWh a year. That is lower total consumption than 52% of the 32 Service Over Counter models in our database.

Safety information
- Plug the unit into a grounded receptacle that matches the plug and voltage on the nameplate, preferably on a dedicated circuit. Never use an extension cord, plug adapter or cut off the grounding prong.
- Unplug the unit or switch off its circuit before cleaning the condenser, replacing lamps or removing panels. Condenser fins are sharp — wear gloves.
- Never store flammable liquids, aerosols or chemicals in the cabinet.
- Lock the casters (if fitted) once the unit is in position, and do not stand or sit on the top unless it is a worktop rated for that load — and even then, never stand on it.
- Glass doors and display panels are heavy and can break if slammed or struck. Close them gently and have cracked glass replaced promptly.
Installation and first-time setup
Measure doorways, hallways and the installation space before delivery. This model is 60 in. wide, 20.4 in. high and 33 in. deep; allow extra room for door swing and airflow around the condensing unit.
- Choose the location
Install the unit on a level floor away from ranges, fryers, ovens, dish machines and direct sunlight. Hot, poorly ventilated spaces force the compressor to work harder, raise energy use and shorten compressor life.
- Provide airflow
Leave the clearances specified in the installation manual around the condensing unit — at the top or bottom of the cabinet, depending on design — and never store product or boxes on top of a top-mounted condensing unit.
- Uncrate and inspect
Remove packaging, shipping brackets and any tape holding doors or shelves. If the unit was laid on its side during delivery, stand it upright for the time the manufacturer specifies before starting it so compressor oil can settle.
- Level and secure
Adjust legs or shim casters so the cabinet is level; this helps doors close and seal on their own and lets condensate drain correctly. Lock the casters and, for mobile units, fit any restraint the manufacturer or local code requires.
- Check the condensate drain
Make sure the condensate pan or evaporator tray is in place. If the unit drains to the building, run the line to a floor drain with an air gap — never directly into a sewer line.
- Start up and pull down
Plug in the unit, set the control and let the empty cabinet reach 41 °F (5 °C) or below and hold it — typically a few hours — before loading product. Verify with a calibrated thermometer, not just the display.
Using your refrigerator
Holding temperatures
| Product | Target setting | Why |
|---|---|---|
| Refrigerated food | 35–38 °F (2–3 °C) | Keeps TCS (time/temperature control for safety) food below the FDA Food Code limit of 41 °F (5 °C) with a safety margin. |
Check and log cabinet temperature at least twice per shift using a calibrated thermometer placed in the warmest area of the cabinet. The FDA Food Code requires a thermometer in every refrigerated holding unit. Change the control one step at a time and give the cabinet a few hours to settle before adjusting again.
Loading for good airflow
- Keep product within the display load limits and clear of the air discharge and return grilles, so the cold air curtain can cover the whole display.
- Keep rear access doors (if fitted) closed between servings, and avoid placing hot or freshly cooked items in the case.
- Restock from refrigerated storage in small batches rather than leaving trays out at room temperature.
Care and maintenance
| When | What to do |
|---|---|
| Every shift | Check and log the cabinet temperature; wipe up spills; make sure doors close and seal. |
| Weekly | Empty and clean shelves, pans and interior surfaces with a mild detergent, rinse, then apply a food-contact sanitizer at the label concentration and let it air-dry. Wipe door gaskets with warm soapy water. |
| Monthly to quarterly | Clean the condenser coil with a stiff brush or vacuum — monthly near fryers and grills, at least quarterly elsewhere. A dirty coil is the most common cause of warm cabinets and compressor failure. |
| Monthly | Inspect door gaskets for tears and gaps, check hinges and self-closing mechanisms, and empty and clean the condensate pan if it is not self-evaporating. |
| Quarterly | Verify the thermometer and display against an ice-point check (32 °F / 0 °C) and clean the evaporator drain line. |
| Annually | Have a refrigeration technician check refrigerant pressures, electrical connections, fan motors and defrost controls. |
| As needed | Clean glass with a non-abrasive cleaner and replace failed lighting; check that anti-condensate heaters keep the glass clear. |
Troubleshooting
Most commercial refrigeration problems trace back to airflow, door seals or a dirty condenser. Work through these checks before calling for service, and consult the code table in your manufacturer's manual if the controller shows an alarm code.
| Problem | Possible cause | What to try |
|---|---|---|
| Cabinet temperature too high | Dirty condenser coil; blocked airflow inside; doors not sealing; hot room; control set too warm. | Clean the coil; rearrange product away from the fan and return; check gaskets and leveling; improve ventilation; lower the setting one step. |
| Compressor runs constantly | Dirty condenser; frequent or long door openings; warm product loaded; low refrigerant. | Clean the coil; reduce door openings; pre-chill product before loading; call a technician if it continues. |
| Evaporator coil iced over | Door left ajar; torn gasket; defrost system fault; humid air entering. | Check doors and gaskets; perform a manual defrost; call for service if the coil keeps icing. |
| Water on the floor or in the cabinet | Clogged condensate drain; drain pan out of place or overflowing; cabinet not level. | Clear the drain line with warm water; reseat or empty the pan; re-level the cabinet. |
| Doors do not close or seal | Cabinet out of level; worn gasket; damaged hinge or closer; product blocking the door. | Level the cabinet; replace the gasket; adjust or replace the hinge; rearrange product. |
| Unusual noise or vibration | Fan blade striking ice or debris; loose panel; cabinet not level. | Clear ice or debris; tighten panels; re-level. Persistent grinding needs a technician. |
| Fog or condensation on the glass | High kitchen humidity; door gasket not sealing; anti-condensate heater off or failed. | Improve ventilation; check gaskets; have the door heater circuit checked if the glass stays fogged. |
Energy use and running costs
The Structural Concepts NE6020RSV SC is rated at 5.08 kWh per day under the DOE test procedure for commercial refrigeration equipment. Running around the clock, 365 days a year, that is about 1,854 kWh — roughly $315 per year, or $26.27 per month, at $0.17 per kWh.
Among 32 Service Over Counter models in our database, this unit uses less energy per day than 52% of them.
The rating is measured with doors closed for most of the test in a controlled room. In a busy kitchen, frequent door openings, warm product, high room temperatures and a dirty condenser coil can raise consumption noticeably.
