MGF8401GR

Overview

The Atosa MGF8401GR is a single-section undercounter refrigerator for commercial kitchens. Its 27-inch class footprint places refrigerated storage below a counter or work surface, keeping ingredients close to a preparation or service area. The cabinet has a solid, right-hinged door and 7.2 cu. ft. of listed capacity. Atosa's specification sheet describes a stainless steel exterior and interior, a reinforced stainless steel top, pre-installed casters and one shelf.

The unit uses a self-contained, air-cooled refrigeration system and R290 refrigerant. Atosa lists a product temperature range of 35°F–38°F. The product manual's technical table lists the capacity as 7.15 cu. ft.; Atosa's specification sheet lists it as 7.2 cu. ft. The MGF8401GR is intended for commercial use.

Key Features

• Undercounter format: Keeps refrigerated stock below the work area for convenient access during food preparation and service.
• Stainless construction: Stainless steel exterior and interior with a reinforced stainless steel top.
• Single solid door: One right-hinged door; the MGF8401GRL is the separately identified left-hinged version.
• Electronic temperature control: An electronic controller manages the cabinet temperature.
• R290 refrigeration: The self-contained, balanced refrigeration system is air cooled. Atosa describes its refrigeration system as suitable for operation under demanding working conditions.
• Variable-capacity compressor: The product information describes a heavy-duty variable-capacity compressor, with energy savings of up to 40% and lower noise compared with a conventional compressor.
• Door sealing and access: A recessed pull handle is easy to clean and helps the door move past nearby objects. Magnetic door gaskets provide a positive seal without door latches; Atosa identifies the gaskets as NSF approved.
• Self-closing door: The specification sheet lists a self-closing door with a stay-open feature.
• Casters and shelf: Pre-installed casters and one pre-installed shelf are listed as standard features.
• Optional drawer cartridge: Atosa lists field-retrofittable drawer cartridge MSF8309227A00 for the MGF8401GR. The accessory is not identified as included with the refrigerator. Its published maximum loading weight is 100 lb per drawer, with listed pan configurations for the top and bottom drawers.

Installation & Requirements

Before connecting the refrigerator, check that the electrical supply matches the rating information on the factory label. The manual specifies an AC 115V outlet and a grounded connection, and advises that the supply have full-fault protection or an automatic circuit breaker. The product specification lists a 115V, 60Hz, single-phase supply and a NEMA 5-15P plug.

Position the cabinet on a flat surface and level it as described in the manual. The manual states that if the unit has been positioned horizontally, it should stand for two hours before activation. Keep the condensing unit's air circulation unobstructed. The manual also says not to install the equipment in an explosive atmosphere and to site it away from direct heat sources such as radiators and direct lighting, as well as direct sunlight and drafts. Do not expose the unit to rain.

The manual describes automatic defrost-water dispersal on models with an integral condensing unit. The MGF8401GR is listed with a self-contained refrigeration system.

Operation

Use the electronic temperature controller to manage cabinet temperature. Atosa recommends setting the refrigerator between 35°F and 38°F for food preservation, which is also the temperature range given on the specification sheet. Allow the controller to maintain the set temperature and keep the refrigerator's ventilation openings clear, as the manual warns against obstructing airflow openings.

The manual includes operating instructions for an XR06CX controller, including viewing and changing a set point and starting a manual defrost. The supplied material does not confirm that this exact controller is fitted to the MGF8401GR, so check the controller installed on the unit before following model-specific button instructions.

Cleaning & Maintenance

For initial cleaning, the manual recommends cleaning the cabinet walls and internal parts with an antibacterial detergent. For plastic parts, use a damp cloth and dry them with a soft, clean cloth. Use little or no water, and do not use harsh or abrasive solvents or detergents. Wear protective gloves when cleaning near parts that may cut, including the evaporator and condenser.

Atosa advises cleaning the condenser frequently to help it receive fresh air. Keep airflow around the condensing unit unobstructed; the manual warns that restricted circulation can adversely affect cabinet operation. The manual also advises keeping ventilation openings clear.

Applications

The MGF8401GR is suited to commercial kitchen areas that need refrigerated storage close to a counter, prep station or service line. Its single door and one shelf support organized storage of ingredients and other chilled items, while its stainless steel top provides a work surface above the cabinet. The optional Atosa drawer cartridge MSF8309227A00 is listed as compatible with this model and offers an alternative storage arrangement; it is an accessory rather than a standard refrigerator component.
