Page 7: Daily Operation
DAILY OPERATION Baking in these units is a combination of heat and belt speed. Some foods may require more top heat or visa versa; other foods may require low top and bottom heat and slow belt speeds. Every product should, therefore, be tested using the separate top & bottom controls and the variable speed control to arrive at the correct balance of heat and belt speed. When changing heat and or belt speed setting allow approx. 5 minutes for the oven to stabilize itself at the new settings. Check the power cord to insure that it is plugged into a proper outlet. Always allow 10 to 15 minutes of preheat time before loading the unit with product. Failure to allow sufficient preheat time will result in unsatisfactory cooking until the unit reaches operating temperature. 1) Turn the master on/off switch to the ON position. 2) Set both the top and bottom heat controls to 500°F (260°C). 3-Phase Control Units, set front heat controls to 500°F (260°C) 3) Turn conveyor speed control to the fastest setting. 4) Allow 10 to 15 minutes for initial warm up, (5 to 8 minutes to reach adjusted temperature, once unit is fully warmed up) CERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE SHOULD BE TAKEN WHILE USING THIS UNIT. - Page 8 CLEANING Preventive maintenance for your Holman Oven consists of the following recommended cleaning procedures.
