MBC65

Overview

The Atosa MBC65 is a horizontal bottle cooler for bars and other commercial beverage-service areas. Its top-opening sliding lids provide access to chilled bottles, while wire dividers help separate and organize the contents. The unit has stainless steel interior and exterior surfaces, an electronic temperature controller and a heavy-duty Embraco compressor using R290 refrigerant.

Atosa’s specification sheet identifies the MBC65GR within the MBC horizontal bottle cooler family. The MBC65 listing and manufacturer’s model designation are commonly presented as MBC65; confirm the model number on the unit’s rating label when checking specifications or parts. The manufacturer notes that specifications may change as products are improved.

Key Features

• Stainless steel construction: Stainless steel exterior and interior, including a stainless steel floor and frame.
• Electronic temperature control: A digital-style electronic controller displays cabinet temperature and allows the set temperature to be adjusted.
• Refrigeration components: Heavy-duty Embraco compressor with R290 refrigerant. The compressor assembly slides out for easier access during maintenance.
• Sliding lids: Easy-glide stainless steel lid or lids with handles; lid locks are standard.
• Organized bottle storage: Wire dividers are supplied. The manufacturer’s specification table lists four dividers for the MBC65GR.
• Bar-service details: A bottle opener and cap catcher are standard.
• Mobility: Pre-installed casters are listed in the manufacturer’s specification sheet.
• Interior visibility: A supplier listing identifies interior lighting for visibility inside the cabinet.
• Forced-air cooling: A supplier product description identifies forced-air cooling to distribute airflow through the cabinet.

• Standards stated in the manufacturer’s specification sheet: Conforms to UL Std. 471 and is certified to CSA Std. C22.2 No. 120.

Installation & Requirements

The manufacturer’s horizontal bottle cooler manual instructs operators to place the cabinet on a flat surface and level it using its adjustable levelling legs. The manual says to lift the cabinet from the exterior of its base rather than applying pressure to its surfaces. If the unit has been positioned horizontally, wait two hours before switching it on.

Allow air to circulate freely around the condensing unit. The manual specifies at least 50 cm of space and warns that restricted air circulation can negatively affect the cabinet. It also directs operators to keep the unit away from direct sunlight, drafts and direct heat sources such as radiators or direct lighting. The stated suitable ambient operating temperature is +50°F to +90°F. The manual says not to install the equipment in an explosive environment.

The manual states that defrost water is dispersed automatically on models with an integral condensing unit. Check the product’s model documentation for the unit’s configuration.

Operation

Use the power switch to turn the cabinet on. At startup, the electronic panel illuminates and displays the current cabinet temperature; the compressor indicator also lights. Following a power interruption, the compressor may restart after a short delay.

During normal operation, the display shows the air temperature inside the cabinet. To view the set temperature, press and hold the SET button for one second. To change it, press SET and use the up or down control to adjust the value, then press SET again to confirm. The family manual gives an electronic-control operating band of 36°F–46°F. Atosa’s MBC65GR specification sheet separately states that the unit maintains 35°F–38°F, while a supplier listing gives 33°F–40°F. Because the published figures do not match, refer to the documentation supplied with the specific unit for its applicable control settings.

The manual identifies beer refrigeration, preparation and sale as possible applications. It also includes a manual-defrost function in its contents; the available instructions do not provide the steps for activating it.

Cleaning & Maintenance

Before use, clean the cabinet’s walls and interior parts with an antibacterial detergent, and wipe plastic parts with a damp cloth. Dry with a soft, clean cloth and use little or no water. The manual cautions against harsh or abrasive solvents and detergents. Wear protective gloves when cleaning near parts that could cut, including the evaporator and condenser.

Clean the condenser frequently, as directed in Atosa’s specification-sheet guidance. The manual also instructs operators to keep the condenser’s air circulation unobstructed. The compressor assembly slides out for easier maintenance. The available manual extract does not specify a cleaning interval or provide a complete maintenance schedule.

Troubleshooting

The instruction manual includes troubleshooting sections for a cabinet that does not operate, a cabinet that does not reach the required temperature, water leakage and unacceptable noise. The available source text identifies these symptom categories but does not include the corresponding diagnostic steps or remedies, so it would be inappropriate to suggest a specific repair procedure here. For service work, the manual says component parts are to be replaced with like components and servicing is to be carried out by factory-authorized service personnel.

Applications

The MBC65 is intended for commercial beverage service, including beer refrigeration, preparation and sale. Its horizontal layout, sliding stainless steel lids and dividers suit bar-back use where staff need access to chilled bottles. The manual states that the appliance is for commercial use only and should not be used to store medical supplies.
