G12000

Overview

The Traulsen G12000 is a one-section, self-contained commercial reach-in freezer in Traulsen’s G series. Its cabinet is accessed through two solid half-height doors, both hinged on the right in the configuration described for this model. Opening one half door at a time can help reduce the amount of cold air that escapes compared with opening a full-height door. The freezer has a microprocessor controller with an LED display, and its listed temperature holding range is -5°F to 0°F.

Capacity figures vary across the supplied product information. The service manual lists 24.2 cu. ft. net capacity for a one-section G-series freezer, while the product listing gives 23.37 cu. ft. of interior space. The product source also cautions that nominal cubic-foot figures may not equal usable storage space. Confirm the cabinet’s practical capacity against the storage needs of your operation.

Key Features

• Two solid half doors: Separate access points help limit cold-air loss when staff retrieve or load product.
• Three coated wire shelves: Epoxy-coated steel shelves resist corrosion, and their wire construction allows air to circulate around stored product. Each shelf is rated for 225 lb.
• Load-sure interior guards: Side-wall guards separate stored items from the interior walls to leave room for airflow around the cabinet.
• Top-mounted refrigeration: The self-contained system is positioned away from floor-level debris and leaves more interior space available for storage.
• Temperature control: The microprocessor controller has an LED display that can show Fahrenheit or Celsius. The manufacturer’s description says the unit can be programmed to operate at -10°F; the product listing gives a holding range of -5°F to 0°F.
• Cabinet access and visibility: LED interior lighting, an exterior light switch, door locks and a 120-degree stay-open feature support loading and retrieval.
• Construction and insulation: The product description identifies anodized aluminum sides and interior, a stainless steel front and doors, a galvanized steel top, back and bottom, and 2-inch foamed-in-place high-density polyurethane insulation.
• Mobility: The unit is supplied with four 6-inch locking casters, which require installation by the end user.

Installation & Requirements

The product listing specifies a 115 V, 60 Hz, single-phase supply, a 9-ft. cord and a NEMA 5-15P plug. The supplied G-series operation manual says to allow either at least 12 inches of clearance above the condensing unit or unrestricted airflow at the back. It also notes that at least 12 inches above the unit is needed for certain maintenance tasks. The freezer’s operating location should be away from extreme heat or cold.

Allow enough space at the side wall for the doors to use their 120-degree stay-open feature. The operation manual says the doors must open at least 90 degrees to provide the maximum clear door width. The power switch is described in the G-series manual as a toggle switch on top of the unit, mounted to the side of the evaporator housing; it ships in the ON position. The G12000’s casters are supplied separately for end-user installation.

Operation

The G12000 uses a microprocessor controller to regulate cabinet temperature. Its LED display shows temperature in Fahrenheit or Celsius, and the product listing states a -5°F to 0°F holding range. The manufacturer’s product description says the unit can be programmed to operate at -10°F. The controller’s customer parameters include high and low thermostat set points, temperature scale, clock and date settings, daylight savings time, defrost lockouts, room-temperature offset, manual defrost and cabinet or evaporator-coil temperature displays.

The supplied G-series operation manual describes a customer-access sequence for changing parameters: press the set button to enter Customer/Service Access; use the set button to move through the three code positions; enter the code 0, A, 1 using the arrow and set buttons; then press set to reach the customer parameters. The manual says to use the arrow keys to find Thermostat Set Point High or Thermostat Set Point Low, press set, adjust with the arrow keys and press set again to save. The high and low set points cannot be identical; the manual says they must differ by at least 1–2 degrees. It lists typical freezer high settings of -3°F to 0°F and typical low settings of -6°F to -4°F. These are general G-series manual examples, not a replacement for the G12000’s stated holding range or the settings appropriate for your operation.

The G-series freezer service information describes automatic and manual defrost operation. During defrost, the control illuminates the defrost indicator, the defrost heater operates, and the compressor and evaporator fans stop. Defrost ends when the coil reaches its end temperature or the maximum defrost time is reached. The service manual says that after defrost, the evaporator fans are delayed to avoid circulating warm air or moisture into the food-storage area. The same manual says freezer cabinet fans stop when a door is open.

Cleaning & Maintenance

The G-series freezer service manual specifies cleaning the condenser coil every six months. It describes using a vacuum cleaner with a fin comb or condenser-coil brush. The G-series operation manual recommends cleaning the stainless-steel exterior with warm water, mild soap and a soft cloth, wiping in the direction of the metal grain. Avoid strong detergents and gritty or abrasive cleaners; do not use chlorine-containing cleansers, which may promote corrosion. Take care not to splash the unit with water.

For ongoing performance checks, the operation manual advises inspecting the unit if wear is visible and checking basic power items if the cabinet is not operating: confirm the cord is plugged in, the fuse is intact or circuit breaker is on, and the power switch is ON. For service involving refrigeration components or electrical diagnosis, the G-series service manual is prepared for trained technicians and warns that it is not intended for unqualified personnel.

Troubleshooting

If the control is blank and nothing runs, the G-series freezer service manual lists an open main circuit breaker, an OFF main switch or an unplugged power cord as possible causes. Check those items first. The operation manual also recommends confirming that the electrical cord is plugged in, the fuse is OK or circuit breaker is on, and the power switch is ON.

If the unit still does not operate properly after those checks, the operation manual directs the operator to contact an authorized Traulsen service agent. The freezer service manual identifies the condenser coil as a routine cleaning item and notes that restricted airflow around stored product can interfere with proper holding temperatures. Refrigeration-system repairs, refrigerant work and electrical testing should be left to qualified service personnel; the service manual states that it is intended for trained Hobart Service Technicians.

Applications

The G12000 suits commercial kitchens that need a single-section reach-in freezer for frozen ingredients and prepared products. Two half doors can be useful in busy service areas where staff access different cabinet levels throughout a shift, while the three shelves provide separate storage zones. The top-mounted system and locking casters may also suit kitchens that need a cabinet with accessible interior storage and a movable base for cleaning or layout changes.
