Installation & Requirements

The supplied installation instructions specify a 115V, 60Hz, single-phase power supply for the MCF8709GR. They state that the supply voltage should remain within ±6% of the unit’s rated voltage. The refrigerator is supplied with a power cord. A thermomagnetic circuit breaker, which is not supplied, must be installed between the mains power point and the refrigerator’s power cable. The manual says this electrical connection must be carried out by professionally qualified personnel.

Before connecting the unit, the manual directs the installer to remove the packaging straps, cardboard and PET protective film. It says to clean the refrigerator with mild detergent and dry it with a soft cloth before use. Position the unit in the coolest, best-ventilated part of the room and do not install it near heat sources or direct sunlight. The provided sources do not specify a clearance measurement.

The manual warns that R290 is a flammable refrigerant and cautions against damaging the refrigerant circuit. It also says to keep ventilation openings clear and not to use mechanical devices or other means to accelerate defrosting unless recommended by the manufacturer. Service involving components should use like components and be performed by factory-authorized service personnel, as stated in the manual.

Operation

The refrigerator uses an electronic temperature controller to regulate its operating parameters. Atosa recommends a refrigerator setting between 35°F and 38°F for food preservation. Product information separately lists a 33°F to 38°F operating range, and the manual’s technical table gives a 33°F to 45°F range for this model. These figures are presented differently in the supplied sources; consult the unit’s documentation and controller information for operating settings.

The manual cautions users not to change the microcomputer parameters privately, explaining that the factory sets them to help avoid damage to the compressor unit or other functions. It identifies the digital control unit as the control for the refrigerator’s parameters and refers operators to the separate digital-control-unit attachment for those parameters. The instructions also describe a keyboard lock: holding the specified keys for more than three seconds displays “OF,” and holding the unlock keys together for more than three seconds displays “on.”

For loading, the product information describes sliding doors that can stay open when opened far enough and close automatically when left slightly open. The cabinet’s interior lighting and glass doors support viewing products without opening the cabinet.

Cleaning & Maintenance

The manual recommends regular cleaning of the refrigerator and specifically advises disconnecting its power-supply cable from the mains before any cleaning operation. For the refrigerator’s surfaces, use mild detergent and dry with a soft cloth. The manual warns against abrasive detergents.

The product information describes flexible magnetic door gaskets that help maintain internal temperatures and keep dust and debris out. Atosa’s spec-sheet guidance says to clean the condenser frequently to give the unit more fresh air. The sources do not provide a specific cleaning interval for the condenser.

Applications

The MCF8709GR is intended for commercial use. Its glass-door merchandising format is suited to displaying and cooling beverages such as beer and soda, as well as other products appropriate for refrigerated display. The two sections, eight shelves and 44.9 cu. ft. capacity provide space for arranging products for staff access or customer viewing in settings such as restaurants, cafés, delis and convenience stores.
