The Roundup SDC-500 Steamer Display Cabinet is a specialized piece of equipment designed for the food service industry, primarily used to quickly steam pre-cooked refrigerated or frozen food products and maintain them at ready-to-eat temperatures. Its core function is to provide a heated, humid environment that both warms food and keeps it at an optimal serving temperature, while also attractively displaying the items to customers.
Function Description
At its heart, the SDC-500 operates as a steamer and a display unit. It features a water pan at the base where water is heated to produce steam. This steam then circulates within the cabinet, warming the food products placed on its shelves. The unit is designed to hold a specific amount of water, indicated by a water tube with "FULL" and "REFILL" lines, ensuring consistent steam generation. A diffuser is included to help distribute the steam evenly throughout the cabinet, preventing hot or cold spots and ensuring uniform heating of food.
The SDC-500 is equipped with an adjustable digital thermostat, allowing users to set and maintain a desired temperature within a specified range. This precise temperature control is crucial for food safety and quality, ensuring that products are held at safe serving temperatures without overcooking or drying out. For added safety, a resettable hi-limit thermostat is incorporated. This safety feature automatically turns off power to the unit if it overheats, typically due to running out of water. Once the unit cools down and water is replenished, the thermostat can be manually reset, allowing the unit to resume operation.
The display aspect of the cabinet is enhanced by internal lighting, which illuminates the food items, making them more appealing to customers. The cabinet features glass panels on its front and sides, providing clear visibility of the products inside. The front door allows for easy loading and removal of food, while the internal shelving system is designed for flexibility and ease of use.
Usage Features
Operating the SDC-500 involves a straightforward process. Before initial use or after cleaning, the water pan must be filled with clean tap water. This can be done either by pouring water directly into the unit through the front door (after removing the diffuser and shelves) or by using the dedicated water tube on the front of the unit. It's important to ensure the water level is visible in the tube and does not exceed the "MAX" line. A caution is provided against pouring water hotter than 120°F (48°C) into a cold unit to prevent injury from resulting steam.
Once the water is added and the diffuser and shelves are reinstalled, the unit can be turned on. During the initial warm-up period, the digital display will cycle through a series of codes, including "8888," "CH-1," the setpoint temperature, and finally the actual cabinet temperature. Users can adjust the setpoint temperature using the "TEMP UP" and "TEMP DOWN" buttons. The unit also offers the flexibility to toggle the temperature display between Fahrenheit and Celsius by pressing and holding the "TEMP SCALE" button.
Loading and removing food products is facilitated by the front door. Tongs or similar utensils are recommended for handling hot food to prevent burns. It is advised to keep the front door closed as much as possible to maintain temperature and humidity, only opening it when adding or removing products. A warning emphasizes keeping the face away from the cover and opening when removing product, as steam can escape and cause injury.
The internal shelving system is designed for user convenience. Shelves are installed using a "notch and tab" system, allowing them to slide in and out without detaching when properly seated. The height of the shelves can be adjusted to accommodate different food product sizes. This involves turning off the power, allowing the unit to cool, opening the front door, and then lifting and repositioning the support racks into different slots on the corner posts. Removing shelves is also simple, requiring an upward lift and slide to release them from the support racks.
Maintenance Features
Regular maintenance is crucial for the SDC-500's proper operation, longevity, and to uphold food safety standards. Daily draining and cleaning are recommended at the end of each serving day. This process begins by turning off the power, unplugging the unit, and allowing it to cool completely. A water tube with a "Tube Lock" mechanism is provided for draining the unit. By lifting the tube lock and rotating the water tube counterclockwise, the water can be drained into a bucket. After draining, the tube is returned to an upright position and locked.
Following drainage, the shelves and diffuser should be removed and washed in hot, soapy water, then rinsed and air-dried. All glass surfaces, both inside and out, should be cleaned with a clean, damp towel, and all metal surfaces wiped with a clean, damp cloth. It's important to wring out cloths before use to avoid dripping wetness. The manual explicitly warns that failure to clean the unit properly each day can lead to permanent damage to the equipment's finish and accessories, which is not covered by warranty.
The manual also provides specific guidelines for cleaning materials, advising against abrasive cleansers or materials that could damage the stainless steel finish. It highlights that chlorides or phosphates in cleaning agents (like bleach or degreasers) can cause permanent damage, such as discoloration, pitting, and cracking, which is also not covered by warranty. Recommended cleaning tips include using a soft, damp cloth with clear water, rubbing in the direction of metal polish lines, and using soap, ammonia detergent, or vinegar solutions for routine cleaning and stain removal.
The SDC-500 uses compact fluorescent light bulbs for illumination. The manual details the steps for replacing these bulbs, which involves turning off and unplugging the unit, allowing it to cool, removing the top cover by unscrewing it, replacing the bulbs, and then re-securing the top cover. It specifies using 25-watt medium base compact fluorescent bulbs and warns against operating the unit without the top cover securely attached.
Troubleshooting information is also provided to address common issues. This includes guidance for situations like no heat or display, flashing error codes ("LO," "HI," "OPEN," "PO"), or fogging glass. For electrical issues or persistent problems, users are advised to contact an Authorized Service Agency, emphasizing that electrical equipment should only be inspected and repaired by qualified service personnel after the unit is unplugged. The manual stresses the importance of using only genuine Roundup replacement parts to maintain warranty validity and ensure proper operation.
