When this condition exists the oven will sound an audible alarm by emitting a triple beep (three quick short beeps) every 2 seconds and it will flash the message “Err too Hot” on the display to alert nearby staff. The audible alarm may be temporarily canceled FOR 3 MINUTES by pushing ADJ/SET. After 3 minutes have expired the oven will begin beeping again. The error message on the display cannot be canceled. The proper action when this alarm is present is to turn the oven off and call for service.

IV. e - TESTING THE OVEN:

Before using the oven for the first time, verify that the oven oper- ates normally.

Check that the oven is connected to the correct power source.

Turn the oven ON at the power switch.

Use the controls to set the HOLDING TEMPERATURE to 1400F.

Check that the oven circulating fans are running.

Check that the heaters ON indicator is lit.

Check that the oven is warming to the displayed holding tem- perature.

NOTE: The cooling fans may not operate when the oven is first turned on. The cooling fans operate only when the thermostat to which they are connected requires it.

Set the TIME to 2 hours, Set the RETHERM TEMP to 2500, push the START BUTTON, check the interior rear of the oven cavity to determine that the oven is heating.

Push the ADJ/SET knob to cancel the cycle, set the TIME to 0, set the HOLD TEMP to 2500F, push the START BUTTON.

Check that the RETHERM TEMP display has been blanked and the HOLD TEMP display is lighted.

Check the interior rear of the oven to ensure that the oven is heating. If all the functions perform satisfactory, the oven is ready for operation.

IV. f - OPERATING THE OVEN:

Main Features

Flexibility-Manual setting of the parameters RETHERM TIME, HOLD TEMP and RETHERM TEMP.

Quick cycle start-Press START at any time during parameter entry to execute a cycle with the existing parameters displayed. The only exception to this is during programming of the stored settings (1 – 9).

Quick cycle abort-Press the ADJ/SET knob at any time during the retherm cycle to return to the Idle State.

-4-

User programming of the 9 most used cycle parameters. Fast recall and cycle start of the pre-programmed cycle parameters.

Very fast recall and cycle start of pre-programmed cycle #1 parameters.

Manual Setting Features

From the IDLE STATE (TIME is blinking) rotate the ADJ/ SET knob to adjust the retherm time. Press START to ac- cept the currently displayed settings and begin the cycle or press ADJ/SET to set the currently displayed time and advance to the RETHERM TEMP setting. RETHERM is blinking. Rotate the ADJ/SET knob to adjust the retherm temperature. Press START to begin the cycle or press ADJ/SET to set the retherm temperature and advance to the HOLD TEMP setting. HOLD is blinking. Rotate ADJ/SET to adjust the hold temperature. Press START to execute the cycle or press ADJ/SET to re-adjust the three parameters. After a cycle is started press ADJ/SET at any time to abort the cycle and return to idle.

Pre-Programmed Cycle Feature

From the IDLE STATE (Time Blinking) press and hold ADJ/SET for 3 seconds. TIME no longer blinks. The current temperature display TEMP displays “P-1” and is blinking. TIME, RETHERM and HOLD display the pa- rameters pre programmed for AUTO CYCLE #1. Press START to execute a retherm cycle with these parameters or rotate the ADJ/SET knob to select one of the other pre-programmed cycle settings (0–9) then press START

. After a cycle is started press ADJ/SET at any time to abort the cycle and return to idle.

Programming The Pre-Programmed Cycles

From the IDLE STATE (Time Blinking) press and hold ADJ/SET for 3 seconds. TIME no longer blinks. The current temperature display TEMP displays “P-1” and is blinking. If necessary rotate ADJ/SET to the desired pre-programmed cycle “P-x”. Press and hold ADJ/SET for 3 seconds. P-x no longer blinks and TIME is blinking. Rotate ADJ/SET to adjust the retherm time and press ADJ/SET to accept the retherm time. RETHERM is blink- ing. Rotate ADJ/SET to adjust the retherm temperature and press ADJ/SET to accept the retherm temperature. HOLD is blinking. Rotate ADJ/SET to adjust the hold temperature and press ADJ/SET to accept the hold tem- perature. P-x has been updated to the currently displayed settings and P-x is again blinking. To program another location rotate ADJ/SET to the desired cycle # then press and hold ADJ/SET for 3 seconds. To return to IDLE press and release ADJ/SET. To start a cycle with the currently displayed settings press START.

Fast cycle Start Using Pre-programmed Setting #1 Press ADJ/SET. While holding ADJ/SET press START.
