INSTALLATION INSTRUCTIONS
A. Qualified Personnel
These installation instructions are for the use of
qualified installation and service personnel only.
Installation or service by other than qualified personnel
ay result in da age to the oven and/or injury to the
operator.
Qualified installation personnel are those individuals,
fir s, co panies or corporations which either in
person or through an agent are engaged in and
responsible for:
•The installation of electrical wiring fro the
electric eter, ain control box or service outlet
to the electrical appliance. Qualified installation
personnel ust be fa iliar with all precautions
required and have co plied with all
require ents of state and local authorities
having jurisdiction. See: National Electrical
code, ANSI/ NFPA 70-1990.
B. Delivery and Inspection
Duke Manufacturing Co., does everything within its
power to insure you receive your oven in good
condition. They are strapped down on heavy wooden
skids and surrounded by heavy “tri-wall” cartons to
prevent shipping da age. They have all been carefully
inspected before they were packaged and consigned to
the carrier.
Upon Delivery of your Duke oven:
•Look over the shipping container carefully noting
any exterior da age on the delivery receipt
which ust also be signed by the driver/
delivery person.
•Uncrate and check for any da age which was
not evident on the outside of the shipping
container. This is called concealed da age. The
carrier ust be notified within fifteen (15) days
of the delivery of the oven and the carton, skid
and all packaging aterials ust be retained for
inspection.
Duke Manufacturing Co. cannot assu e liability for
loss or da age suffered in transit. The carrier assu es
full responsibility for delivery in good order when the
ship ent was accepted. However, we are prepared to
assist you in filing any freight clai .
C. Location of the Oven
Proper planning and place ent of the oven will give
you the best results in ter s of long ter user
convenience and satisfactory perfor ance. We urge
you to give adequate thought in the place ent of your
oven prior to its arrival.
•The oven should be placed in an area which is
free fro drafts and accessible for proper
operation and servicing.
•The area around the oven ust be kept clear of
co bustible aterials. A ini u of one (1)
inch fro the left or right side, three (3) inches
fro the rear and eight (8) inches fro the floor
ust be aintained between the oven and any
co bustible or non-co bustible surface.
It is also i portant not to obstruct the natural flow of
ventilation air if the oven is to operate properly. This
oven should not be installed on a curb base or sealed to
the wall. Either condition can prevent proper
ventilation of the blower otor. The blower otor has
a ther al protection device which will trip because of
excessive a bient te peratures at the side of the oven.
If the device trips continually, this condition should be
corrected i ediately to avoid da aging the oven
per anently.
Before aking any connections to the oven, check the
rating plate to be sure the oven specifications concur
with the voltage and phase to be supplied to the oven.
The rating plate and serial nu ber data are located
behind the otor access cover on the right side panel.
D. Electrical Connections
Each Duke 5/9 Half-Size Convection Oven is rated at
8.0 KW.
Your oven is supplied for connection to a 208, or 240
volt grounded circuit. The electric otor and control
circuits are powered internally and do not have a
separate power supply.
Before aking any connections to these units, check
the rating plate to assure that the voltage and phase
rating of the oven is co patible with the electrical
supply. When installing, all ovens ust be electrically
grounded in accordance with local codes or in the
absence of local codes, with the National Electrical
Code, ANSI/NFPA 70-1990 (in Canada - CSA Std.
C22.1).
Wiring diagra s are located on the inside of the otor
access panel on the right side of the oven.

E. Oven Assembly
Before asse bling and installing the oven, please check
to ake sure that all necessary parts are present. In
addition to the oven itself, there will also be legs, feet or
casters. (For double sections, retaining clips, flue
connector and iscellaneous hardware.) Please check
the interior of all oven sections for the parts needed to
asse ble and install your oven(s).
F. Leg Attachment
• Once the oven has been removed from the
carton, lay it on its left side (the side
ithout the controls).
• Hold the leg and align ith the matching
holes in base and leg flange. Carefully
start the 5/16-18 bolts, (avoid cross-
threading), by turning clock ise and
tighten to the nearest full turn. A total of
(12) 5/ 16-18 x 3/4 bolts, flat ashers and
lock ashers are required to secure all
legs.
• Once legs are secured, add t o (2) storage
shelves bet een the four (4) legs. Secure
these by using the 1/4-20 x 3/4 self-
threading scre s. After completion
carefully lift the oven to an upright
position.
To level the unit, raise or lower the adjustable feet as
required.
G. Caster Installation
• Casters are available as an option for
double oven sections. They are packed
inside the oven for shipment.
• To install follo same procedures as for
leg attachment. Position and secure the
casters to the four (4) insert nuts in the
base bottom.
NOTE: They have 1/2-13 threads and will only fit
the large insert nuts in the botto . The two
locking casters should be installed on the front
legs for easy access and better stability.
H. Double Sections
The necessary short legs, storage shelves and hardware
are shipped with these sections. Follow sa e
procedures for leg attach ent as described above.
Once legs and shelves are in place and the oven is
placed in an upright position install the stacking
brackets that secure the top oven to the botto oven.
The stacking brackets ount at the rear corners of each
section. Re ove the screws fro the corner of the
oven that atches the holes in the stacking brackets.
Install the brackets with the new screws provided.
I. Adjustments Associated ith
Installation
Each oven section and all its co ponent parts have
been tested thoroughly and inspected before your oven
was shipped fro the factory. However, it is so eti es
necessary to further test or adjust the oven once it has
been installed. Such adjust ents are the responsibility
of the Dealer or Installer. These types of adjust ents
are not considered defects, rather a nor al and routine
part of the proper installation of the equip ent.
These adjust ents include but are not li ited to:
• adjustments and recalibration of the
thermostat
• adjustment to the doors, leveling
• and tightening of fasteners.
Note: No installation should be considered
co plete without proper inspection and, if
necessary, any adjust ents by qualified service
or installation personnel.

MAINTENANCE INSTRUCTIONS
These aintenance instructions are for the use of
qualified service personnel only. Service by other than
qualified personnel ay result in da age to the oven
and/or injury to the operator.
Qualified service personnel are those individuals, fir s,
co panies or corporations which either in person or
through an agent are engaged in and responsible for
repair or servicing of co ercial food preparation
equip ent, who are experienced in such work, fa iliar
with all precautions required, and have co plied with
all require ents of state and local authorities having
jurisdiction.
If you should require assistance in the selection of a
qualified service agency, please contact Duke
Manufacturing Co.’s Service Depart ent at 800-735-
3853.
A. Adjustments
Quite often alfunctions which are attributed to
defects ay be repaired by adjusting certain parts rather
than replacing the .
B. Door Adjustment
The door switch is located behind the lower front
cover, on the right or left side. (Fig. 1) The door switch
(A) is activated by a ca (B) which is ounted to the
door’s hinge pin with a set screw. Position the door so
it is nearly closed but not latched. To adjust the ca :
• Loosen the set scre and rotate the cam
until you hear the s itch click.
• Tighten the set scre in the cam.
• Test the door to make certain the s itch
ill make contact ith the doors closed.
• Replace the compartment cover.
Cleaning of the Oven
The stainless steel on your oven can be kept clean with a good stainless steel cleaner, an of which are on the arket.
The painted surfaces should be wiped clean regularly with a MILD detergent. Moisten a cloth and wipe down the oven
while it is COLD. Wiping down an oven while it is hot will cause streaking and otherwise unsatisfactory results. Once
the oven is clean, it can be wiped down with light oil.
Porcelain oven interiors should be cleaned regularly using a degreasing agent. For heavier deposits a co ercial oven
cleaner such as Dow Oven Cleaner, Easy-Off, or Mr. Muscle can be used. Care ust be taken to prevent these alkaline-
type cleaners fro co ing in contact with any alu inized steel surfaces in the oven, including the blower wheel.
The racks and rack supports can be re oved and soaked in a solution of a onia and water.
Make certain that all parts are thoroughly rinsed before returning to use.
NOTE: Never steam clean or hose do n ith ater. Electric component ill fail due to moisture.

OPERATION OF CONTROL
The ZP Convection Oven Controller is designed to
si plify your cooking process and allow your
foodservice operators to spend ore ti e with the
custo ers and other i portant responsibilities. Quality
control of your food product is assured through the
various features, notification displays and alar s
designed into the controller.
There are two ethods of baking with the ZP control:
Shelf Timer Baking
Event Baking
SHELF TIMER BAKING
The ZP Convection Oven Controller provide five
individual shelf ti ers. Shelf ti er baking allows the
user to add product to the oven as needed and set
individual ti ers for each new ite .
NOTE: You ay add si ultaneous or subsequent trays
of the sa e or different products to the oven if they
bake at the sa e te perature and fan setting. Products
which are set up for event baking will not have shelf
ti er baking available.
EVENT BAKING
The ZP Convection Oven Controller provides one-
touch control of the entire baking process by allowing
you to divide each product bake cycle into six distinct
stages or “events”. Each stage can be progra ed for
ti e, te perature, fan speed, controller-co pensated
ti e, or straight ti e countdown ode.
Using event baking with uffins, for exa ple, yields
excellent results. Here is an exa ple of a typical
controller bake cycle for an oven load of uffins, half
corn and half blueberry:
Event 1: Begin at 400•F for 5 inutes with fan on.
Event 2: After 5 inutes, when the uffin batter has
risen to the top of the cups, we’ll progra the
fan off for the next 10 inutes to allow the
uffins to rise high and evenly.
Event 3: We’ll now turn the fan back on and set oven
te perature to 375•F for the next 5 inutes,
per itting an even bake through the center of
the product.
Event 4: During the last 5 inutes of the bake cycle, we
want to set the uffin peaks and finish the
off to a golden color, so we’ll increase the
te perature to 400•F.
NOTE: When event baking is to be used, the
countdown ti e displayed is the su of all the stages.
CONTROLLER RESET
In rare situations such as a lightening strike near
the facility, the controller may lose its program or
become “locked”. To reset the controller simply
turn the po er s itch off, ait several seconds and
turn the unit back on.
