HEC60D

Overview

The Hobart HEC60D is a deep-depth model in Hobart’s DEC/HEC electric convection oven series. It has one cooking cavity, a porcelain interior and five racks. The oven doors open independently. Its electronic control system includes cook-and-hold and pulse functions. The manual also identifies additional racks and an open stand with a lower storage rack as available accessories; stacked ovens use a stacking kit.

The HEC60D model designation is associated with Hobart model number ML-43880 in the supplied documentation. The manual covers several related DEC/HEC models, so electrical service and other installation details should be checked against the HEC60D data plate and the wiring diagram supplied with the oven.

Key Features

• Deep-depth cavity: The HEC60D is identified as a deep-depth model.
• Electronic controls: The control panel includes cook and hold time functions, a cook-temperature control, Start/Stop and Pulse buttons, a Ready light and a thermometer button.
• Convection airflow: A two-speed, 1/2 HP blower motor is standard equipment for the DEC/HEC series.
• Temperature control: The series is equipped with a 500°F (260°C) thermostat.
• Five racks: Five racks are furnished; additional racks are listed as accessories.
• Porcelain interior: The manual gives daily cleaning instructions for the porcelain oven interior.
• Independent doors: The oven doors open independently.

Installation & Requirements

Check the oven for shipping damage immediately after unpacking. If damage is found, retain the packaging and contact the carrier within 15 days of delivery. Before installation, verify that the electrical service agrees with the specifications on the data plate, which is located inside the bottom front cover. The manual cautions not to lift the oven by its doors or door handles.

Choose an installation location that allows adequate clearance for servicing and proper operation. The basic oven must be installed on legs or mounted on a modular stand. The manual advises against placing it on a concrete base or another support that restricts airflow underneath, noting that doing so may void the warranty. When installing the supplied leg assemblies, position the oven on its back without scratching or damaging it, attach the four leg assemblies to the oven bottom using the furnished bolts and lockwashers, then carefully raise it to its normal position. For a modular stand or cabinet base, the manual describes using locating studs to secure the oven to the base or stand.

The oven chimney and flue extension are stored at the rear of the oven in the motor compartment. The manual instructs the installer to fasten the chimney to the top rear of the oven, positioning its flanges under the top cover, and to attach the flue extension. For stacked ovens, the manual describes using the stacking kit and flue extensions to direct exhaust upward through and above the top oven. The stacking instructions also include joining the ovens with a conduit nipple and locknut. Stacked ovens are an installation arrangement, not a change to the HEC60D’s single-cavity construction.

In Canada, the manual requires installation in accordance with local codes and the Canadian Electrical Code, CSA Standard C22.2 No. 3, identified in the manual as Electrical Features of Fuel Burning Equipment. Electrical and grounding connections must comply with applicable electrical codes. Disconnect electrical power and place a tag at the disconnect switch before working on the circuit. The manual directs the installer to connect the supply conduit at the bottom of the oven, follow the wiring diagram supplied with the oven, and replace the wiring compartment cover after making connections. Match the supply to the oven data plate; do not infer the required connection from the model name alone.

Operation

The HEC60D control panel has an On/Off/Cool Down switch, thermostat control and display, timer display, two-speed fan control, light switch, vent damper control, thermometer button, Start/Stop button, Cook button, Pulse button and Hold button. The controls provide cook-temperature, cook-time and hold-time functions. A Ready light indicates the ready status shown on the control panel. The manual’s model table identifies electronic controls and cook-and-hold and pulse options for the HEC60D.

When the Cook button light is lit and product is not being timed, the temperature display shows the set cook temperature. Pressing the Thermometer button overrides that display with the actual oven-cavity temperature for eight seconds. The Thermometer button light remains on while actual temperature is displayed and goes out when the display returns to the set temperature.

The supplied manual excerpt does not provide the full HEC60D control sequence, so use the model’s control labels and complete operating instructions rather than applying instructions for the mechanical or solid-state related models. For end-of-day cooling, the manual instructs operators to turn the thermostat to OFF, set the On/Off/Cool Down switch to ON, and leave the door ajar while the fan cools the oven. When the oven has cooled sufficiently, turn the switch to OFF and clean the oven.

Cleaning & Maintenance

Turn the oven off and disconnect the electrical supply before cleaning. The manual calls for daily exterior cleaning with a clean, damp cloth. Clean the porcelain oven interior daily with soap or detergent and water, rinse thoroughly, and wipe dry with a soft, clean cloth.

The manual also provides separate directions for an optional stainless-steel oven interior. For routine cleaning, use soap or detergent and water, rinse thoroughly, and dry with a soft, clean cloth. For burned-on food or grease that resists routine cleaning, an abrasive cleanser mixed into a paste may be used with stainless-steel wool or a sponge. Rub in the direction of the grain, rinse with clear water, and dry with a soft cloth. The same approach is given for heat tint. These stainless-steel directions apply only if the oven has the optional stainless-steel interior; the standard interior identified for the series is porcelain.

Troubleshooting

The manual states that a power outage causes the oven to shut down automatically. When power is restored to the lines, the oven resumes normal operation. The provided manual text does not include specific HEC60D error-code descriptions or fault remedies, so it does not support assigning a cause or repair to an error message. For electrical work, the manual requires disconnecting power and tagging the disconnect switch before working on the circuit.

Applications

The HEC60D is an electric convection oven for commercial kitchen cooking. Its five racks, deep-depth configuration, temperature control and cook-and-hold and pulse functions support kitchen workflows that involve cooking or holding products in the oven. The supplied material does not specify a rated food capacity, rack spacing, cooking results or a model-specific menu, so those should not be assumed from the specifications listed here.
