MCF8703

Overview

The Atosa MCF8703 is a bottom-mount, two-glass-door merchandising freezer for commercial use. The glass-door format makes stored products visible, while the two-section cabinet provides space for organizing frozen inventory. The Atosa manual lists the MCF8703GR and MCF8703ES versions with the same core technical specifications: 44.77 cu. ft. of volume, a temperature range of -8 to -1°F, and overall dimensions of 54.5 × 31.5 × 84 inches.

The manual classifies this unit within the bottom-mount reach-in series and states that the appliance is intended for commercial use only. Its stated maximum shelf load is 176 lb. Do not exceed that load when arranging products on a shelf.

Installation & Requirements

The manual says connection to the mains must be carried out by professionally qualified persons. The unit is supplied with a power-supply cable. A thermomagnetic circuit breaker, which is not supplied, must be installed between the mains power point and the freezer’s power-supply cable. The electrical information for the MCF8703 variants is 115 V, 60 Hz, single phase. Before connection, confirm that the supply voltage corresponds to the rating; the manual specifies that the supply voltage should remain within ±6% of the unit’s rated voltage.

Place the freezer in the coolest, best-ventilated part of the room, away from heat sources and direct sunlight. Keep the ventilation openings clear of obstruction, as directed by the manual. Before use, remove the packaging restraints and cardboard, remove the PET protective film, then clean the unit with mild detergent and dry it with a soft cloth. Once connected through the circuit breaker, the manual directs the operator to check that the freezer is operating as indicated by the pilot light incorporated in the main switch.

The manual warns of fire risk associated with flammable materials and specifically identifies the risk of fire and explosion with flammable R290 refrigerant. It also cautions against damaging the refrigerant circuit, using mechanical devices or other means to accelerate defrosting unless recommended by the manufacturer, and using electrical appliances inside food-storage compartments unless they are of a type recommended by the manufacturer.

Operation

The freezer’s listed operating temperature range is -8 to -1°F. The manual refers operators to the attached digital-control-unit instructions for control parameters and notes that the control-unit manual is important in the event of service. It cautions users not to change the microcomputer parameters themselves, explaining that the products are set before leaving the factory and that unapproved changes may damage the compressor unit or affect other functions. After connecting the unit, check the main-switch pilot light as described in the installation instructions.

Cleaning & Maintenance

The manual recommends cleaning the refrigeration unit regularly and specifically calls for cleaning each month. Disconnect the freezer’s power-supply cable from the mains before carrying out any cleaning. Clean the surfaces with mild detergent, then dry them with a soft cloth. Do not use abrasive detergents. The manual emphasizes that correct, regular maintenance is important to the smooth operation and service life of the equipment.

Applications

This commercial freezer is suited to restaurant, food-service, and retail environments that need frozen storage with a visible glass-door display. The two-door merchandising format can be used to present frozen products while keeping them in a freezer operating within the temperature range specified for the model.
