Manufacturers Introduction
The Duke AHPO or EPO Proofer Oven were developed
in response to Customer’s need for uniform baking
capabilities to provide consistently high, “just baked”
bread quality .
The Duke Proofer Oven utilizes Duke’s unique directional
convection airflow 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 while
reducing food scrap/waste and simplifying operating
procedures.
The low profile oven won’t block the view of menu boards
and will easily roll through a standard height door . The
oven and proofer doors are field reversible with a drip
channel on the proofer door to prevent water from
dripping on the floor.
Full width doors on the oven and proofer help to display
and merchandise fresh baked bread to the customer.
The controls are simple to operate, there are two timers
for independent timing of the proofer and oven.
The full width oven and proofer cavity will accept
standard ½ size or full size sheet pans.

current if an electrical short
occurs. When using an ap-
propriate plug it must be
plugged into an outlet that is properly installed and
grounded.
Consult a qualified electrician or servicer if grounding
instructions are not completely understood, or if doubt
exists as to whether the oven is properly grounded.

if there is a difference. If the phase is wrong, a qualified service technician can change the wire connections
inside the oven to correct the problem. See the illustration on page 4 for phase conversions. If the voltage is
wrong, the heat elements must be changed. Call Duke to get new elements.
