MGF8451GR

Overview

The Atosa MGF8451GR is a one-section, 52-inch refrigerated chef base for commercial kitchens that need cold storage directly below countertop cooking equipment. Its one-piece, reinforced stainless steel top provides a support surface for countertop equipment, while two drawers give staff access to refrigerated ingredients or other stored products at the cooking station. The unit has 8.4 cu. ft. of capacity and includes six stainless steel pans sized 12 × 20 inches.

The stainless steel exterior and interior suit frequent use in a foodservice setting and support routine cleaning. A side-mounted, self-contained refrigeration system and electronic temperature controller support refrigerated storage without requiring a separate remote refrigeration unit. The product listing gives a temperature range of 34°F–40°F; Atosa’s specification sheet recommends 35°F–38°F for food preservation.

Installation & Requirements

The supplied Atosa manual is titled for model MGF8405GR but includes technical characteristics for the MGF8451GR chef base and installation instructions for the refrigeration equipment family. Follow the equipment’s own rating label and the applicable manufacturer instructions when confirming the electrical supply and placement requirements for this unit.

The manual specifies connection to an AC 115 V outlet and instructs operators to check that the supply conforms to the factory-label requirements. It also calls for full safety protection or an automatic circuit and a grounding connection. The MGF8451GR specification sheet identifies 115 V, 60 Hz, single-phase power and a NEMA 5-15P plug.

For placement, the manual says to set the cabinet on a flat surface and level it using the leveling legs. It also says to lift the cabinet from the exterior of the base and not to move it by applying pressure to the surface. The MGF8451GR specification sheet lists pre-installed casters, so consult the model-specific documentation for handling and positioning details applicable to this chef base. The manual instructs users to wait two hours before activation if the equipment has been positioned horizontally. It cautions against installation in an explosive environment and says to keep air circulation free around the condensing unit. It also advises locating the cabinet away from direct heat sources, direct sunlight and drafts. The manual does not provide a numerical clearance dimension in the supplied text.

Operation

Atosa’s specification sheet recommends a refrigerator setting between 35°F and 38°F for food preservation. The product listing gives the unit’s operating temperature range as 34°F–40°F. Use the electronic controller to check and adjust the setpoint, and follow the food-handling procedures applicable to the operation.

The supplied manual describes the XR06CX controller. To view the setpoint, press and immediately release the SET key, or wait about five seconds for the normal display to return. To change the setpoint, press and hold SET for more than two seconds. When the setpoint appears and the temperature-unit indicator blinks, use the arrow keys to change the value. Press SET again to store the new setpoint, or wait ten seconds. The manual also describes starting a manual defrost by holding the DEF key for more than two seconds.

The manual states that defrost-water disposal is automatic on models with an integral condensing unit. The MGF8451GR is listed with a side-mounted compressor; confirm the applicable defrost and drainage details in the documentation supplied with the specific unit.

Cleaning & Maintenance

Before first use, the manual says to clean the cabinet walls and internal parts with an antibacterial detergent. For plastic parts, use a damp cloth, use little or no water, and dry with a soft, clean cloth. It warns against harsh or abrasive solvents and detergents. During cleaning, wear protective gloves and take care around parts that could cut, including the evaporator and condenser.

Atosa’s specification sheet advises cleaning the condenser frequently to provide it with fresh air. The source does not give a fixed cleaning interval. Keep the condensing unit’s airflow unobstructed, as the manual states that restricted air circulation can detrimentally affect the cabinet. The manual also says refrigerant and insulation-blowing gas require special disposal procedures; consult a service agent or similarly qualified person when disposing of the appliance.

Applications

The MGF8451GR suits restaurant cooking lines and other commercial foodservice stations where operators want refrigerated product storage close to countertop cooking equipment. Its two drawers and included pans can support organized access to ingredients during service, while the stainless steel top provides a surface for countertop equipment. The 52-inch width, 33-inch depth and 26 3/5-inch height should be checked against the intended equipment layout and countertop equipment before selection.
