6. Allow the oven and proofer to pre-heat for at
least 30 minutes. An audible alarm will sound
(3 short chirps) when the oven and/or proofer
reach the ready state. Your Duke Proofer Oven is
now ready to operate.
If there are any problems refer to the Trouble

4. Watch for a light fog to appear on the interior
door glass; the proofer is ready to be loaded
with dough.
5. Increase humidity, if door glass does not fog as
the humidity is set too low; press button of
the (Relative Humidity). The RH% will
increase on the Proofer Recipe Information Bar.
6. Decrease humidity if water is running down
door glass as the humidity is set too high; press
button of the (Relative Humidity).
The RH% will decrease on the Proofer Recipe
Information Bar.
7. Load the rst proofer section with dough and
touch UPPER, MIDDLE or LOWER Start Timer
, depending on where dough is loaded.
This will prevent over-proong of the dough
remaining in proofer after the rst load has been
moved to the oven. The remaining time will be
displayed in the button area and the progress
bar will change to visually show elapsed and
remaining proof time.
Since the proofer can hold more pans than the
oven can bake, an alarm beeps and LOAD NEXT
TRAY is displayed in the Main Tool Bar 1/3rd of
the time thru the proofer cycle so that loads
can be staggered. Load the next proofer section
with dough and touch Start Timer for the
respective section.
NOTE: You can cancel an active timer with touch
and hold for 2 to 3 seconds on the count down
timer.
8. When the proof is complete, an alarm for the
respective timer will beep to alert the operator
which level is ready to be moved to the oven.
Touch the Timer to cancel the alarm.

at any time during the proof or at the end of a
proong cycle. You must add time in 5 minute
increments.
10. Adjust the time, if necessary, depending on type
of dough and desired results.
11. Bake bread when dough rises to desired size.
NOTE: Excessive humidity on the door glass is
probably caused by a humidity setting that is too
high or by having the humidity on when there is
no dough loaded in the proofer.

BAKING TIPS
• Always select the oven recipe and allow preheat
time prior to loading product. Only load when
the Oven Recipe Ready to Start Timers screen is
displayed. Load the oven with six pans of dough
and touch the start button.
• If the bread color is uneven, reduce temperature
and extend bake time in recipe (see
Programming Controls).
• If the bread is too dark, reduce the bake time in
the recipe (see Programming Controls). If the
bake time is reduced and the bread is still too
dark, reduce the temperature by 15° F (10° C)
and bake longer.
• When baking partial loads, center the pans in
the oven and start loading at the bottom shelf
and work up to the top.
• Opening oven door allows heat to escape. Under
normal conditions, quick loading and unloading
will not be a problem. If door is left open too
long, oven performance will be aected.
NOTE: The Proofer Oven has a "Default" run
mode. This mode is only active when there is a
Touchscreen control communication error and
with power to the balance of the controls. This
mode allows for your Proofer Oven to mantain
approximately 350° F (177° C) in the baking oven
and approximately 105° F (41° C) and 80%RH in
the proofer. When the Proofer Oven is operating in
this mode, you will witness the Proofer and Oven
lights blinking o for approximately 2 seconds
every minute. This mode allows you to continue
using your Proofer Oven for baking and proong
until the unit is properly serviced.
The "Default" run mode is disabled with an open
oven door.
