Installation, Operation, and Care of ELECTRIC COMBI, CONVECTION & STEAM OVENS SAVE THESE INSTRUCTIONS GENERAL The Electric Combi, Convection & Steam Ovens are single compartment ovens that provide convection heating and/or steaming in the cooking chamber. Humidification can be provided by the internal steam generator or by water injection (water vaporizes on contact with the hot oven interior). The Hobart Combi Electric ovens are sized 6, 10, or 20 levels high. The 6 level ovens are Half depth

LEGS OR CASTERS WARNING: THE OVEN MUST BE BLOCKED AND STABLE BEFORE INSTALLING LEGS OR CASTERS. Raise up and block the oven a minimum of 10" from the floor. Threaded holes are provided at the four corners underneath the oven; screw the threaded stud of the four legs or optional casters into the threaded holes. Four flanged legs allow anchoring to the floor (anchoring hardware not provided). Casters with brake should be installed at front, casters without brake, at rear. Available Installation

WATER REQUIREMENTS Proper water quality can improve the taste of the food prepared in the oven, reduce liming in the steam generator, and extend equipment life. Local water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about your local water supply prior to installation. Recommended water hardness is 2.0

DRAIN CONNECTION CAUTION: In order to avoid any back pressure in the oven, do not connect solidly to any drain. 1 Extend the drain line from the 1 /2" NPT drain pipe extending from the bottom of the oven at the rear to an open gap-type drain. Drain piping must have suitable pitch, have appropriate support along its length, and have no connection to other piping. The material used in the drain line should be heat resistant to at least 212°F. ELECTRICAL CONNECTION WARNING: ELECTRICAL AND GROUND

BEFORE FIRST USE Before using the oven for the first time, it must be "burned in" to release any odors that might result from heating the new surfaces in the oven. Operate the oven at 480°F for 45 minutes in Convection HOT AIR Mode. Perform CONFIGURATION MODE — PROGRAMMABLE CONTROL, pages 30 – 31. OPERATION WARNING: THE OVEN AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR SERVICING THE OVEN. THE COOKING COMPARTMENT CONTAINS LIVE STEAM. STAY CLEAR WHEN OPENING DOOR. DOOR OPENING

LOADING THE OVEN Open the door. Place the product to be cooked in suitable containers and slide into the racks or place the containers securely on shelves in the oven. When loading a 6 or 10 level oven with the landing table (Fig. 6), the bottom frame of the rack should be secured by the rotary lock. Move the loaded landing table to the front of the open oven; secure the landing table to the oven by actuating the locking-clamp (or use your body to hold the landing table against the oven). Rot

UNLOADING THE OVEN Allow the door to be 'slightly-opened' for a few seconds to allow hot air and steam to escape. Stand behind the door while opening. When unloading a 6 or 10 level oven, move the landing table so the clamp locks the landing table to the front of the oven (or use your body to hold the landing table against the oven). Remove the landing table handles and clamp them to the bottom of the hot oven pan rack. Carefully roll the hot pan rack onto the landing table platform, making s

PROBE The Probe Temperature defines the final temperature of the product for any cooking phase. The cooking cycle stops when the product temperature reaches the probe temperature setting. Total Cooking Time is not known or entered when using the probe. COOKING WITH THE PROBE There are two ways to control the oven temperature when using the Probe . . . 1) Setting the Oven Temperature at a constant value. The oven climbs to the set point and the product cooks at that temperature. The cooking

BAKING (Convection Baking – HOT AIR) Convection Baking involves baking, browning, roasting, etc. without adding steam or moisture to the process. Hot air is fan-circulated to maintain even temperatures throughout the oven. Preheating the oven before loading the product is recommended. Automatic Convection Baking can be set up so the buzzer sounds when the Cooking Time has elapsed or when the product's internal temperature has reached the Probe Temperature set point.

STEAMING (Steam Mode only) Steam cooking is used for stewing, poaching, and gentle cooking of products cooked in water. Steam flows without pressure into the oven. The fan circulates the steam to all parts of the oven. Allow the steam generator to preheat for 4 - 5 minutes if starting from cold. Also, it is recommended that you preheat the oven using the Convection Baking (HOT AIR) Mode. Automatic Steaming can be set up so the buzzer sounds when the Cooking Time has elapsed or when the produ
