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. The Hobart Combi Electric ovens are sized 6, 10, or 20 levels high. The 6 level ovens are Half depth only. The 10 and 20 level ovens are either Full or Half depth. All models include a Digital programmable control.
LOCATION Allow space for operating the oven. Do not obstruct the ventilation ports above the oven. To provide ventilation access, allow 1" clearance on the left side of the oven and 21/2" clearance at the rear. A suitable amount of space (18" minimum) should be provided on the right side of the machine for operation, cleaning and service. DOOR OPENING The standard oven is delivered with the door hinged on the left. If the door opening needs to be changed, contact your authorized Hobart Service office.
DRAIN CONNECTION In order to avoid any back pressure in the oven, do not connect solidly to any drain. Extend the drain line from the 1" 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 (100°C).
OPERATION 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 SWITCH The oven is equipped with a feature that shuts off power to the oven cavity when the door is opened. The oven will resume cooking once the door is closed. DOOR OPENING AND CLOSING To open the door (Fig. 1), turn the handle to the horizontal position. Allow a few seconds for steam to escape before pulling the door open.
UNLOADING THE OVEN Unloading 6 or 10 Level Ovens Open door partially to allow hot air and steam to escape. Remove the product from the rack guides or racks in the oven. Close the door.
