AWC1012-TF

Overview

The Atosa AWC1012-TF is an indoor walk-in cooler for refrigerated food storage in commercial kitchens and foodservice operations. Its nominal dimensions are 10′ × 12′, with a 7′6″ nominal height. The cabinet is assembled from insulated floor, wall and ceiling panels, and includes a reinforced floor, top-mounted refrigeration and a 36-inch door. Atosa lists the cooler’s operating temperature as 35°F–38°F.

For planning purposes, the specification sheet lists the overall exterior dimensions, including the condensing unit, as 120″ × 144″ × 117″. The walk-in cabinet itself is 120″ × 144″ × 91″ externally, with interior dimensions of 112″ × 136″ × 82″ in the installation manual. The specification sheet recommends an 11-foot ceiling when the condenser is installed.

Key Features

• Insulated panel construction: 4-inch foamed-in-place wall and ceiling panels with cam locks. The specification sheet lists an R-value of R-29 for cooler panels.
• Reinforced floor: A reinforced floor is standard for this model.
• Door and access: A 36-inch door has diamond-tread kick plates, heated frame, heavy-duty Kason hinges, a door closer and a handle with a lock and inside safety release.
• Lighting: Standard lighting includes a digital LED light and a 48-inch ceiling-mounted LED.
• Top-mounted refrigeration: The drop-in system is mounted on top of the walk-in. Atosa describes it as a low-noise system.
• Ramp: The installation manual’s AWC1012-TF component list includes an extend ramp.

Document revision note: The supplied installation manual identifies R404A as the factory refrigerant, while Atosa’s 09/25 specification sheet lists R448A for the AWC1012-TF-IL/IR. Confirm the refrigerant on the equipment nameplate and applicable documentation for the specific unit.

Installation & Requirements

The installation manual calls for a firm, level and smooth supporting surface. A level foundation matters to panel alignment, door operation, gasket sealing and condensation removal. The manual specifies that indoor walk-ins must be in an environmentally controlled space, with relative humidity kept between 30% and 60% and a dew point of 50°F or less.

Before setting panels, the manual calls for at least 2 inches of clearance around the exterior of the panels for airflow. Check space for the door swing and heated pressure relief before assembly. Each panel is identified by a part number; the manual instructs installers to group panels by type and refer to the installation drawing supplied with the unit. Floor and ceiling panels use cam locks, and wall panels lock together along their vertical joints. The manual describes engaging the section latches with the supplied hex wrench and checking that adjoining panel edges are aligned and flush.

The AWC1012-TF exploded-view list identifies a two-motor top evaporating unit and a 3 HP condensing unit. The refrigeration-system manual gives an outdoor ambient operating range of 5°F to 113°F (-15°C to 45°C) for the condensing unit. It calls for a location with good ventilation and smooth exhaust, convenient access for installation and maintenance, and a reliably load-bearing support if installed on a roof or platform. It also cautions against nearby strong heat sources, equipment exhaust, strong steam or flammable gas, and locations where the unit could be buried in snow or affected by garbage or oil mist.

The specification sheet recommends an 11-foot ceiling with the condenser installed; the overall listed height is 117 inches. The electrical connection described in the refrigeration-system manual uses L1, L2 and ground terminals. The manual states that the main power supply wires are not provided by the factory. Confirm that the planned electrical supply matches the unit’s 208–240V, 60Hz, single-phase specification and 30A rated current, and that the listed 40A breaker requirement is addressed.

Operation

Atosa specifies a cooler temperature range of 35°F–38°F and recommends setting the refrigerator within that range for food preservation. The walk-in has a digital LED light. Its door includes a lock and an inside safety release, along with a closer and spring-loaded hinges. The heated door frame is a standard feature. The control and refrigeration components are part of the top-mounted system.

Cleaning & Maintenance

Atosa’s specification sheet advises keeping the unit’s airflow unobstructed and cleaning the condenser frequently to give it more fresh air. The refrigeration manual also identifies convenient maintenance access and good ventilation as considerations when selecting the condensing-unit location. No cleaning chemicals, detailed cleaning procedure or maintenance interval are specified in the provided material.

Applications

The AWC1012-TF provides walk-in refrigerated storage for restaurants, commercial kitchens and other foodservice operations that need room for chilled ingredients and supplies. Its 10′ × 12′ nominal footprint suits operations planning for larger-volume cold storage, subject to confirming the cabinet dimensions, door access, installation space and electrical requirements at the site.
