Page 5: Heating Elements
Inspect all heating elements in the unit for breakage. Every unit is properly tested prior to leaving the factory, but damage may of occurred during shipping. If a broken tube is found, do not apply power to the unit. If everything checks out, Turn on Main Power Switch, Turn both heat controls and conveyor belt speed control to the maximum setting and check all heater tubes and conveyor for proper operation. COOLING SYSTEM After the unit is initially turned on, allow 5 to 8 minutes for the fan cooling system to come on. Once on, check the air intake area located under the unit and be sure that there is a sufficient flow of air into the control box. Keep area under the unit clean from obstructions that may result in restricted air flow to the control box. Restricting the air flow will cause the unit to run hotter then designed, causing the Hi-Limit to turn unit off. See the Oven Components section on page 7 for control box & Hi-Limit Reset locations. FINAL CHECK If all heaters and conveyor systems are operating properly, switch the master on/off switch to the OFF position and allow unit to cool, the fan will continue to circulate air, cooling the unit until the internal temperatures have been decreased. If a problem is discovered during any of these start-up procedures, immediately switch the master on/off switch to the OFF position and notify the Star Service Department at (314) 634-6303. ELECTRICAL CONNECTION Before making any electrical connection to this unit, check that the power supply is adequate for the voltage, amperage and requirements stated on the rating plate. WARNING A wiring diagram is included herewith. Disconnect the unit from the power source before installing or removing any parts.

Page 6: Stacking Ovens
STACKING OVENS When stacking two Holman Proveyor Ovens a stacking spacer with an external air duct MUST be used to prevent overheating of the control box of the top oven. 1. If a cart is to be used with units, place bottom unit on cart and align leg holes of unit with the holes on the cart. Insert 3/8" bolts through cart and into leg holes to secure bottom unit to cart as shown below. 2. Place stacking spacer on top of bottom oven with internal air duct facing up and towards the rear of the oven. 3. Mount external air duct on stacking spacer as shown below. External air duct must be installed for cooling system of top unit to function properly. 4. Screw cap screws (Qty 4) into leg hold on the top oven. 5. Place top oven on stacking spacer. Cap screws will set into cut out in top of stacking spacer to lock unit into position. OVEN STACKING SPACER OVEN EQUIPMENT STAND NOTE: Air intake of top unit must fit over the internal air duct of stacking spacer to allow airflow into the control box of the top oven. -
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 12: Troubleshooting Guide
A. UNIT WILL NOT HEAT, CONVEYOR BELT WILL NOT MOVE. 1) Be sure the main circuit breaker is switched to the ON position and there is power to the outlet. 2) Check to see if the oven is plugged in and all controls are turned to the ON position. 3) Be sure the Hi-Limit Reset Button is pushed in. 4) Call the Star Service Help Desk at (314) 634-6303. B. 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 right side. If this reactivates the heater tubes, see Hi-Limit Reset Section below. 3) 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 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. NEVER OPERATE UNIT WITHOUT CRUMB TRAYS IN POSITION AS THIS CAUSES CAUTION OVERHEATING IN THE CONTROL BOX. D. CONVEYOR WILL NOT TURN, UNIT HEATS PROPERLY. -
