Timer Settings
The oven can be set to turn itself on and off. After the AUTO ON/OFF TIMER is set, the POWER ON
OFF button can be pressed to turn the oven off. This will not disrupt the AUTO ON/OFF setting. Electrical
power to the oven must remain on.
NOTE: Auto On/Off has restricted access when P21 (Advanced Energy Savings Mode) is set to 1.
(14°C) cooler than the oven temperature. Press the
COOL DOWN button. The COOL DOWN mode is exited
when the oven reaches the new set temperature, or if
door is opened when temperature is 25°F (14°C) below
set temperature, or by pressing any button.

parameter P17 (Temperature setback time), it will revert to the Setback temperature stored in parameter
P18 (Setback temperature) setup.
Backup Battery
The clock is backed up by a lithium battery which keeps the clock circuitry operating when all external power
is off. If the battery becomes low or dead while the external power is off, the display will read 12:00 (12
hr mode) or 0:00 (24 hr mode) and will not increment until a new time is set. The clock will operate with a
dead or missing battery, but must be set each time external power is turned on. Batteries must be replaced
when low or dead to avoid corrosive damage to the circuitry. Contact your local authorized service ofce.

Oven Preheat
For best results, the oven must be preheated to bake temperature before baking begins.
1. The door must be closed for oven to heat. The rack carrier will lift and rotate only during timed
bake.

out of the home position, the rack carrier will lift and turn to the unload position when the door is opened.
2. Press the POWER ON OFF button to turn the oven on.
3. Press the UP or DOWN arrows next to the SET temp window to enter the desired baking temperature.
Actual temperature of the oven will appear in the OVEN TEMP window.
4. For optimum steaming capability, allow 30 minutes after the oven has reached the set temperature
for the steam system to charge.
5. The oven is now ready for baking operations.
Basic Operation
The oven and its parts are hot. To prevent burns, use hot pads or protective mitts
when loading or unloading the oven.
Hot air and steam are released from the oven interior when the loading door is
opened. To avoid burns, open the door slowly and keep clear of the opening.

Loading Procedure
1. Type B and C rack carriers are equipped with stops on both ends. For B lifts, ensure stop ap is in
the up position to load the rack on the rack carrier. For C lifts, push rack stop to the left after rack is
loaded.
2. Roll the rack into the oven so the end brackets channel onto the rack carrier. When using racks
equipped with pan stops, load racks so stops will prevent movement of trays toward user when racks
are unloaded. Position pans so they do not extend beyond the rack. If the pans extend beyond the
rack it may cause the rack to get jammed when rotating.
3. Close the loading door. The rack carrier will lift and rotate only during timed bake.
Unloading Procedure
The oven and its parts are hot. To prevent burns, use hot pads or protective mitts
when loading or unloading the oven.
Hot air and steam are released from the oven interior when the loading door is
opened. To avoid burns, open the door slowly and keep clear of the opening.
1. Press STOP and/or open the loading door to silence the beeper.
2. Wait for the rack carrier to stop and lower.
3. For B lifts, push the rack stop down to unload the rack from the rack carrier. For C lifts, push rack
stop to the right to open.
4. Roll the rack from the rack carrier.
5. Close the loading door.
Cooling Oven
• To cool the oven more than 20 degrees below its current temperature; change SET TEMP to the
desired new temperature, open the oven door, and press COOL DOWN. The SET TEMP display
will alternate between ‘COOL’ and the SET TEMP until the oven has cooled. When the oven has
reached the set temperature, the alarm will beep and the control will return to normal operation.
Closing the oven door or pressing any control button during Cool-Down mode will also return the
control to normal operation.
• The VENT control can provide a means of cooling down the oven. When the oven is in the off
mode and the door is open, press the VENT button once to start or stop the circulation fan. Vent
light will be lit. The fan will also stop when the door is closed or the oven is put into the on mode.
• If the oven temperature is more than 20 degrees higher than the set temperature, and the bake
timer is not activated, the oven will automatically open the vent. The vent will remain open until
the oven temperature is within 20 degrees of the set temperature.
Operational Hints
• On the initial startup, the oven temperature will default to the factory setting of 375°F (190°C)
unless changed.
• During a baking cycle, the START and STOP buttons control the TIMER, STEAM, and FAN DELAY
settings only. They have no effect on the oven heat. When the TIMER times out, the oven heat will
cycle on and off to maintain the set temperature. Care should be taken not to overbake products.
• To adjust the temperature during a baking cycle, press the UP or DOWN arrows in the Oven Temp
section to enter the new temperature. If P20 (Restricted operator mode) is set for 1 then oven
temperature cannot be changed during the bake cycle.
