IMPORTANT: Read the following safety and operation instructions to avoid injury and to avoid damage to equipment or property.
Plug unit into a properly grounded electrical outlet of the correct voltage, size, and plug configuration for this unit. We recommend usage on an individual branch circuit of at least 15 amps for best results. Failure to do so may result in decreased performance of the oven.
The oven should never be operated on or near combustible materials. Caution should be taken because of the hot surfaces attained during use.
Exterior surfaces on unit may get hot. Use caution when touching these areas to avoid injury.
Unplug oven when not in use.
INITIAL START UP
Before you use your new Wisco 721 Convection Oven, you will want to follow the steps listed below in order to get rid of any oil, film, etc. that may still be on the oven from the manufacturing process.
The unit may initially smoke during this process.
• Clean the oven with a mild detergent inside & out
• Set the oven’s temperature control board to 500°F
• Allow the oven to run for approximately 30 minutes
• After this cycle, you are now ready to start cooking
OPERATING INSTRUCTIONS
TEMPERATURE
Most products require lower temperatures than suggested for deck or range ovens. A standard temperature reduction of 25°F-30°F is recommended as a starting point. Actual baking will vary pending product weight and consistency. If the edges of the product are done and the center is still raw or there is extensive color variation, reduce the thermostat setting by 15°F-25°F until the desired results are achieved. Excessive temperatures will not reduce baking time.
TIME
Convection ovens generally bake 20% faster than deck or range ovens even though lower temperatures are used. Most recipes can be converted by having shorter cooking times and/or reducing your cooking temperatures.
• Frozen food products will require more time than refrigerated products
• 3 trays of food product will require more cook time than 1 tray of food product
PRODUCTS
Load the oven from the bottom up. To ensure even baking, equal amounts of similar products should be used on each pan.
