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 cooking chamber reaches operating temperature. Even though the elements can reach there operating temperature very quickly, a certain amout of time in needed to allow the cooking chamber to reach its 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) Turn conveyor speed control to the fastest setting. 4) Allow 15-20 minutes for initial warm up, (5 to 8 minutes to reach adjusted temperature, once unit is fully warmed up) 5) Once the unit is pre-heated, adjust the controls to the proper setting for the product you are preparing. C ERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE SHOULD BE TAKEN WHILE USING THIS UNIT. CAUTION OVEN COMPONENTS ADJUSTABLE HEAT SHUTTER (QTY 2) - Page 8 CLEANING Preventive maintenance for your Holman Oven consists of the following recommended cleaning procedures.

UNIT WILL NOT HEAT, CONVEYOR TURNS PROPERLY. 1) Check to see if the top and bottom heat controls have been turned to the maximum setting. 2) Press the Hi-Limit Reset Button located underneath the conveyor belt on the inlet side. If this reactivates the heater tubes, see Hi-Limit Reset Section below. 3) If not, call the Star Service Help Desk at (314) 634-6303. C. HI-LIMIT (HEAT) RESET. Your Holman conveyor oven is equipped with an automatic activated temperature limit switch which interrupts the heater tube connections if the air temperature in the control box exceeds 190°F (88°C) This limit switch can be reset manually by pushing the button in the center of the switch which is located on the power cord side panel, on older models its on the right side under the conveyor belt. See Oven Components on Page 7 for location. Unit will not reset until internal temperature has fallen below 190°F (88°C). NOTE: THE HI-LIMIT SWITCH CAN BE ACTIVATED IF THERE IS NOT A PROPER AMOUNT OF AIR FLOW BEING GENERATED BY THE COOLING FAN. IF THIS OCCURS: 1) DISCONNECT UNIT FROM POWER SOURCE. 2) Check to see if the air intake area (center of the control box, bottom of unit) is free of dust, grease or other obstructions. 3) Check to see if crumb trays (heat reflectors) are in place. If the Hi-Limit Switch can not be reset, call the Star Service Help Desk at (314) 634-6303. -
