INTRODUCTION
These appliances are intended to be used for commercial applications, for example in kitchens of
restaurants, canteens, hospitals and in commercial enterprises such as bakeries etc., but not for continuous
mass production of food.
The Duke TSC (Touch Screen Control) Proofer Oven was developed in response to the Customer's need
for uniform baking capabilities and to provide consistently high quality just-baked bread.The Duke
Proofer Oven utilizes Duke’s unique directional convection airow technology that provides even heat
distribution and a uniform bake without the need for turning pans during the bake cycle. This enhances the
quality and consistency of the baked products, reduces food scrap and waste while simplifying operating
process.
The low prole oven won’t block the view of menu boards and will easily roll through a standard height
door. The oven and proofer doors are eld reversible with a drip channel on the proofer door, which
prevents water from dripping on the oor.
Full-width doors on the oven and proofer help to display and merchandise fresh baked bread to the
customer.
The full-width oven and proofer cavity will accept standard half-size or full-size sheet pans.
The TSC models feature a simple color LCD touch screen control that allows users to quickly select from
pre-programmed recipes for baking and proong. Advanced features are also included for custom recipes
plus user accessible information for operating instructions and maintenance information.

TECHNICAL DESCRIPTION AND APPLICATION NOTES FOR TSC PROOFER OVEN BACK FLOW
PREVENTER SYSTEM
Check with your local authority having jurisdiction
regarding approvals for connecting the Duke TSC
Proofer Oven to a potable water supply before
making any plumbing connections. Plumbing code
requirements vary, but European Union (CE) and
other jurisdictions require a back ow prevention
device that is factory-installed or available as a
kit (P/N 600187). The back ow prevention device
used on Duke TSC Proofer Ovens protects water
supply systems by preventing the reverse ow of
non-potable water into the potable domestic water
system. The device consists of two independently
acting check valves, internally force-loaded to a
normally closed position and designed/constructed
to operate under intermittent or continuous
pressure conditions. The two main components of
the Duke back ow preventer system are:
• Dual Check Valve type back ow preventer that
conforms to ANSI/ASSE standard #1024 and is
CSA standard B64.6 certied.
• Inlet water strainer equipped with 100-mesh
screen and installed up stream of the back ow
preventer. The screen is conveniently located
on the rear panel of the proofer, below the back
ow preventer, for easy access during cleaning/
replacement.

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 maintain
approximately 370° F (188° 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.
5. When the bake is complete, an alarm will beep
to alert the operator. Touch the Timer or
open the oven door to cancel the alarm.
6. You can add 1 minute to baking time by
touching the button adjacent to the count
down timer. This can be done at any time
during the bake or at the end of a baking cycle.
You must add time in 1 minute increments.
7. Adjust the time, if necessary, depending on
type of dough and desired results.
