5. Set the conveyor speed for 1
to 10 minutes using the up
and down arrow buttons. The
conveyor speed is the
amount of time it takes for
the item to go through the
bake chamber, which is the
bake time.
6. Verify the temperature controller’s set point for
baking and adjust if necessary:
− The set point appears in the upper display.
− Adjusting the set point requires a “Set Point
Only” display, where nothing is in the lower
display. To get to “Set Point Only”, press the
Scroll key until the lower display is blank.
− From this “Set Point Only” display, use the up
and down keys to adjust the temperature.
Holding in the pressed key will adjust at a
faster rate.
7. Turn the HEAT switch to the “ON”
or “I” position. The HEAT ON LED
lights to show that the oven is
heating.
IMPORTANT
On gas ovens, if the HEAT ON LED does not light, OR
if the oven does not heat, the gas burner may not have
lit. Turn the HEAT, BLOWER, and CONVEYOR
switches to the “OFF” (“O”) position. WAIT FOR AT
LEAST FIVE MINUTES before restarting the oven.
Then, restart the Daily Start-up procedure.
8. With the HEAT ON LED lit, press the Scroll key
one time from the “Set Point Only” display. The
actual temperature will appear in the lower
display.
9. Wait while the actual temperature reaches the set
point. Higher set point temperatures will require a
longer wait. The oven can reach a temperature of
500°F (232°C) in approximately 15 minutes.
10. After the actual temperature has reached the set
point, allow the oven to preheat for 10 more
minutes to stabilize the temperature.
B. Daily Shutdown Procedure
1. Turn the BLOWER and HEAT switches to the
“OFF” or “O” position. The blowers will remain in
operation until the oven has cooled to below 200°F
(93°C).
2. Make sure there are no products left on the
conveyor inside the oven.
3. Turn the CONVEYOR switch to
the “OFF” or “O” position.
4. After the oven has cooled below 200°F (93°C) and
the blowers have shut off and the cooling fan has
shut off, switch the circuit breaker/fuse disconnect
to the off (open) position.
C. Power Failure
In case of power failure, turn all switches to the “OFF”
(“O”) position and remove the product. After the power
has been restored, perform the normal start-up
procedure. If HEAT was switched off for less than 5
minutes, WAIT FOR AT LEAST FIVE MINUTES
before restarting the oven.
