HRO330P

Overview

The Hobart HRO330P is a programmable rotary oven in Hobart’s HRO Series. The manual describes HRO Series ovens as using rotating, self-basting spits or flat baking racks, together with convection and radiant heat, for thorough cooking and even browning. Stainless steel interiors and exteriors are intended to make cleaning easier. Tempered-glass doors at the front and back and quartz lighting allow the food to be seen during cooking.

The HRO330P is an oven model. The manual identifies HRW models as the versions with an upper oven and a lower warming cabinet; it does not describe a lower warmer cabinet for the HRO330P. The P models, including the HRO330P, are listed as having programmable controls.

Key Features

• Programmable controls: The HRO330P control panel supports programmed Cook, Grill and Warm/Hold settings. Programs are selected using menu buttons.
• Rotating cooking: The series uses rotating spits or flat baking racks. The manual says the spits are self-basting and that rotisserie inserts can be intermixed.
• Combination heat: The manual describes convection and radiant heat for cooking and browning.
• Visibility: Tempered-glass doors are fitted at the front and back, with quartz lighting.
• Grease handling: The removable grease drawer has a drain plug for draining excess fat and can be removed for cleaning.

Installation & Requirements

Check the oven for shipping damage immediately after unpacking. If damage is found, keep the packaging and contact the carrier within 15 days of delivery. Before installation, check that the electrical service matches the machine data plate, located on the right side panel near the controls.

Install the oven on a level surface. The manual specifies minimum clearances of 10 inches from the rear, 10 inches from any glass, and 4 inches from each side panel. The location must also allow room for servicing and for proper operation of the front and rear doors. The manual warns that the oven should not be accessible to customers because hot glass and parts can cause burns, although it may be positioned where cooking can be observed.

To access the electrical connection point, remove the right side panel and follow the wiring diagram attached to the oven. The manual requires electrical and grounding connections to comply with applicable national and local electrical codes. It states that the electrical supply cord and plug should be supplied by the installer. Disconnect electrical power and tag the disconnect switch before working on the circuit. Confirm the exact electrical requirements from the unit’s data plate; the supplied excerpt does not provide HRO330P voltage or amperage values.

Operation

Before first use

Unplug the oven before cleaning. Before its first use, clean the oven and accessories inside and out with warm soapy water, rinse thoroughly, and dry with a soft, clean cloth. Avoid getting water on the quartz lamps. The manual calls for a burn-in at the maximum temperature setting of 450°F for four hours to release odours from new surfaces. Smoke with an unpleasant odour is described as normal during this period.

Programming the menu controls

To program a menu, first press its menu button; the LED lights. To enter Program mode, press and hold the two indicated control buttons together until the time display shows “PROG,” which the manual says takes approximately two seconds. The menu LED then flashes. Program the Cook function first by setting its temperature and time. The programmed temperature range is 32°F to 480°F, and the maximum Cook time is 5 hours and 59 minutes.

Next, select the Grill function and set its temperature and time. Set the Warm/Hold function’s temperature last. The manual states that Warm/Hold has no programmable time; attempting to set one causes the buzzer to sound for three seconds. When programming is complete, press the flashing menu button to lock in the settings. The manual says the displays then show the Cook temperature and time. Repeat the programming process for other menu buttons as needed.

Cooking and unloading

The manual advises distributing product evenly when loading. It also warns that opening the door does not stop the rotisserie or cooking process. Turn the rotisserie off before removing spits or baskets. To bring the next utensil into position, the manual describes advancing rotation by turning the rotisserie to Manual, then removing the utensil.

Cooking time and temperature depend on the product’s initial temperature, size, shape and other factors. The manual’s cooking table includes whole chicken, Cornish hens, duck, turkey, roast beef and pork ribs. Its listed cooking times are identified as times for the HRO101, so they should not be treated as HRO330P cooking times.

Grease drawer

Empty the grease drawer as needed, taking care if the grease is warm. Open the drawer, place a suitably large bucket or vessel under the drain plug, and unscrew the plug. When draining is complete, tighten the plug. When the machine is idle, empty and remove the drawer, then wash it in a sink with warm soapy water. A soft, non-scratching pad may be used on hard soil.

Cleaning & Maintenance

Unplug the oven before cleaning. The manual warns that hot glass, grease and parts can cause burns. Clean the exterior glass with a damp cloth or commercial glass cleaner. Use only a damp cloth on the control panel. Remove the rotisserie, spits, bottom plates, grease drawer and other removable parts; wash them in a sink with warm soapy water, rinse thoroughly and dry with a soft, clean cloth. Return the clean grease drawer to the bottom of the oven.

Clean the oven interior with warm soapy water, then rinse and dry it with a soft, clean cloth. Remove spills from the grease drawer and wipe it dry with a clean cloth. Do not clean the quartz lamps with soap and water. The manual instructs operators to wipe the lamps with a cloth soaked in alcohol, avoid touching them with bare hands, and handle them carefully because they can break.

Monthly, clean the ventilation grate and fan blades at the top of the oven with warm soapy water, then rinse and dry them. To reach the fan blades, remove the ventilation grate by unscrewing the nuts on either side of the vents. The manual says to remove the nut in the centre of the fan blade by turning it clockwise. Reinstall the parts in reverse order after cleaning. Before performing maintenance, disconnect the electrical power supply.

Applications

The manual identifies whole chickens, Cornish hens, whole ducks, whole turkeys, roast beef and pork ribs as products that may be cooked in the HRO Series. The HRO330-size capacity is listed as up to 35 chickens across seven spits. Product size, shape and starting temperature affect cooking results, so the manual advises adjusting times and temperatures to suit the operation. The HRO330P can suit commercial foodservice settings preparing rotisserie items for service, display or batch cooking.
