SEE DETAILED description IN CLEANING AND DELIMING INSTRUCTIONS. OM-CBE-10G 13 Typical Operations 1. Preheating When the power switch is turned on the burners light and raises the cavity temperature to 200 degrees (the set point). No cooking mode has been selected and the display shows SELECT MODE on the first line and PREHEAT on the second line. When the power switch is turned on from a cold start the unit turns on the center burner first and the cavity fan is off to allow the flue to heat gradually. After a few minutes all three burners will light. When the temperature rises above 180 degrees (20 degrees below the set point) PREHEAT disappears from the display. The fan is allowed to operate at the selected speed. The temperature continues to rise to the set point at which time the burners will cycle on and off to keep it there. At any time the user may select any cooking mode. However, if steam or combo modes are selected water will not enter the reservoirs until after the unit is heated. 2. Flame-out detection When the oven is started the cavity temperature should rise above 135 degrees in ten minutes. If the burner didn’t start or has gone out the temperature at that time will be too low. The message “Burner not on. Relight” will be displayed and the oven will turn off. Follow the RE-LIGHT instructions. 3. Ready indication The ready condition is satisfied (the oven is ready) when the set cavity temperature is reached. In the idle condition (no cooking mode selected) the set point is 200 degrees. In steam mode it is set to generate steam. In combo and oven modes it is set by the user. When the oven is not ready, the word PREHEAT is displayed and the temperature display flashes. Once the oven comes up to ready PREHEAT disappears and the temperature display stops flashing. If the door is opened and the oven is loaded with cold food the cavity temperature will fall. However, since the ready condition has already been met the temperature display will not flash. If the cooking mode is changed then the temperature display will resume flashing if the current cavity temperature is more than 20 degrees below the new set point, that is, the oven is not ready. Once ready state is achieved with the new settings the flashing will stop. The same sequence occurs if the temperature setting is changed. 14 OM-CBE-10G 4. Water level If combo or steam mode is selected one or more of the reservoirs will fill with water (after the unit is heated). There are two water level sensor probes, one for the center reservoir and one for the right reservoir. When the water level drops below a sensor probe (boils off) the associated water valve opens and refills the reservoir. Whenever a fill or drain valve is first opened a timer controls the fill and drain times. If the water level has not changed when this timer finishes an error message is displayed telling which valve (fill or drain) in which reservoir (1 or 2) took too long to change. If it takes too long to fill or drain a reservoir it could mean that the sensor probe is contaminated and should be cleaned. Fill timeout could also mean that the water pressure is very low or the main water valve is turned off. Drain timeout could mean that the drain is plugged and should be cleaned. 5. Door When the door is open for five minutes or more the burners are turned off. As soon as the door is closed the burners resume normal operation. Whenever the door is open the cavity fan is stopped and the timer (if running) is paused. During the clean cycle the rinse water is stopped whenever the door is open. 6. Cavity fan The cavity fan normally operates at high speed. Pushing the Fan Speed LO button selects the low speed. Whenever the cooking mode is changed the fan speed is automatically set to high. 7. Timer When the power switch is turned on the timer is paused, the colon (:) in the TIMER display does not flash to indicate pause. Adjust the TIMER knob (the lower knob) for the desired cooking time in hours and minutes. Push START to allow the timer to run, the colon flashes indicating that it is running. It also locks the temperature knob. At the end of the timing period the beeper sounds and the CANCEL indicator flashes. Push CANCEL to stop the beeper. Note that this is all the timer does; it is a simple kitchen timer. It does not stop any cooking process, it simply alerts the operator that the timer has timed out. Typical Operations (cont.) 8. Light When the LIGHT button is pushed the door lights turn on to illuminate the cavity. When the button is released the lights stay on for five seconds and automatically turn off. 10. Spray Nozzle The spray nozzle is used in the clean cycle to rinse the cavity walls. Both of the nozzles should be oriented with the flats vertical and the slots up. (see photo) 9. Condensate spray When a steam-water valve is first turned on a large puff of steam may be created if the water is sent to a hot reservoir. Part of this puff of steam goes out the overflow drain. During this time the condensate spray is turned on to condense the steam and cool drain water. When a drain valve is opened it discharges hot water into the oven drain. During this time the condensate spray is turned on for a longer period to cool the drain water. The condensate spray is turned off when not draining to conserve water. Wash spray nozzle. Maintenance It is important to properly maintain this equipment. A regularly maintained unit will provide many years of trouble free operation. Recommended maintenance schedule is outlined below: 1. Daily A. clean the interior and exterior (outer panels) of the oven per cleaning procedure described in this manual. B. drain, clean and air dry the condensate drip pan located below the door. C. Open the inner glass panel and check both inner and outer glass for cracks. The inner glass pane should securely snap in place for proper operation. Check for signs of loose fit. If cracks are found, do not operate the unit until the glass is replaced. smooth operation and signs of misalignment or wear. If the door does not move freely or sags, do not operate the unit until corrected. B. check the door latch for smooth operation. If necessary lubricate the latch spring with a food grade PTFE lubricant. C. check the door gasket at all four (4) corners and along its entire length for cracks, cuts or abrasion. A leaking gasket could cause severe burns. Replace the gasket as needed. D. If your unit is equipped with Groen supplied stand and optional pan racks, check the pan racks for a secure fit.
