Page 11: General Operation & Programming
Do not open the oven door during baking, as this will change the baking characteristics of the oven and make it difficult to determine a final program. If the product is overdone on the outside and underdone on the inside, reduce the baking temperature. If the product is pulling away from the edge of the pan, the temperature is too high or the cooking time too long. A convection oven is a mechanical piece of equip- ment. The same control settings will always give the same results. If the results vary, problems may be because of changes in the product preparation. Power Switch ECOH-AP Control Panel The Control panel consists of the following items. Detailed operational descriptions are given later this section. Pulse Fan Switch & Hi/Low Speed Switch Power Switch: Turns the oven on and off Pulse Fan Switch: Pulse Setting: Fan will only turn ON, when the oven is calling for heat. Heat Call Light Fan Setting: Fan is on continuously, speed is determined by the Hi/Low switch. -
Page 12: Loading
General Operation & Programming cont. Loading Here are some things to remember when loading your oven. • When loading and unloading the oven, stage products and racks so the oven door is opened for the least amount of time. • Be sure that racks are level within the oven. • Bent or warped pans can greatly affect the evenness of the cook or bake. • If using baker’s parchment, be sure the parchment does not blow over the product. That will create an uneven bake. • Load each shelf evenly. Spaces should be maintained equally between the pan and oven walls, front and back. • Do not overload pan’s this will create an uneven bake. • For best baking results, load the oven from the center out during random loading. ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM COMBUSTIBLE MATERIALS. CAUTION KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS. -
Page 13: Maintenance
MAINTENANCE • Oven interiors should be wiped down daily and thoroughly cleaned weekly using warm water and mild detergent. DO NOT use caustic cleaners. • The appliance should be thoroughly checked at six-monthly intervals by a qualified technician (heating unit, mechanical stability, corrosion...) with particular emphasis on all control and safety devices. CLEANING • Always start with a cold oven. • The stainless exterior can easily be cleaned using stainless steel cleaner. • Always follow the cleaner manufacturer’s instructions when using any cleaner. • Care should be taken to prevent caustic cleaning compounds from coming in contact with the fan wheel. • The oven racks, rack slides, may be cleaned outside the oven cavity using oven cleaner. • Using any harsh chemicals will result in the removal of the ETC coating and etching of the porcelain below it. The oven interior should only be cleaned using a mild soap and a non metal scouring pad. DO NOT use caustic cleaners. • Always apply stainless steel cleaners when the oven is cold and rub in the direction of the metal’s grain. -
