Installation
DOMESTIC
Use a separate amp AC
circuit. Only industrial extension
cords with proper wire size
should be used; size 16/3 wire for
distance up to 25 feet, and size
14/3 for distance up to 50 feet.
INTERNATIONAL
Use a designated amp AC
circuit. Only industrial extension
cords with proper wire size (2.5
sq. mm) shall be used.
Make sure there is a proper electrical
wall outlet located within reach of the
cord and plug attached to the press.
Then place the press in an area which
allows for “swing clearance” of the
lower platen plus vertical and horizontal
clearance of the press itself.

Solid State Controller
This controller has three (3) control
features:
1. Temperature – May be set from
100°-425°F (38°-163°C)
2. Time – Time may be set from 1
second to 10 minutes.
3. Counter – Cycle counter counts
the number of applications from
1 to 9999 (see additional Notes –
Counter).
4. “2Lower” (Fig. A) Refers to
models using upper and lower
heated surfaces.
Controller Operation
1. Viewing the Modes of Operation:
-2- DP1300 2/04
4. Resetting the Counter
PRESSING DOUGH:
For best results, your dough should be
proofed before pressing, but it will also
press directly out of your refrigerator.
Flour is not required to press a crust
and should not be dusted on any part of
the machine.
D1400C Cabinet & Compressor
• To view the set points of
temperature, timer and counter,
press MODE button to view the
desired mode of operation.
2. Changing Temperature:
• Press MODE button until
temperature is displayed.
• Press and hold SET button
while pressing the UP (↑) and
DOWN (↓) arrow buttons to
desired temperature setting.
3. Changing Time:
• Press MODE button until time
is displayed.
• Press and hold SET button
while pressing the UP (↑) and
DOWN (↓) arrow buttons to
desired timer setting.
The DISENGAGE switch may
be pressed anytime during a
cycle, and the cycle will stop
immediately, and the timer will
reset.
• Press MODE button until the
counter is displayed.
• To Reset the Counter (# of
Cycles), simultaneously push
UP (↑) or DOWN (↓) arrow
buttons (approx. 5 seconds).
1. After connecting the air hose line
from the compressor to the press,
plug it into the properly rated
electrical outlet for your press
and air compressor cabinet.
Verify the electrical requirements
against the nameplate on the
back of the press and air
Incoming air to machine shall
not exceed 90 psi as this will
damage internal parts and void
the machine warranty!

compressor cabinet.
Note: The compressor portion of the
machine has a separate on/off switch
located on the rear of the lower cabinet.
2. Switch the DP to the ON
position.
Note: Initial temperature setting of
150°F has been shown to be acceptable
for most dough formulations; however,
you may have to determine the best
temperature for your own dough by trial
and error testing of your product at
different temperature settings.
3. Set the timer in accordance with
the following information:
2-4 seconds –For warm dough
with moderate yeast content.
2-6 seconds – For room
temperature dough with
moderate yeast content.
6-8 seconds – For cold dough
right out of the refrigerator with
low yeast content.
Remember that the timer does not
actuate until the upper platen mates
with the lower platen and resistance
is felt.
4. Set the thickness control lever to
“thick” or “thin” or anywhere in
between these settings as your
product requires.
Note: Diameter and thickness is
determined through experimenting with
your own dough and is a product of
dough weight, temperature, pressing
time, and thickness setting.
5. Swing open the lower platen and
apply a quick spray of a good
water based food release on the
-3- DP 2/04
lower platen. Doughpro offers
its own food release spray
NATURALLY CLEAR Model
No. DPPC1. (See our catalog
and price list for information.)
Note: This spray will not
the taste of your crust in any
way.
6. Place your pre-portioned ball of
dough in the approximate center
of the lower platen. Add another
dash of spray to the top of the
dough ball.
7. Close the platen and, with both
hands, press the two green
buttons on each side of the
machine simultaneously.
8. Hold the buttons in until
resistance is felt then release at
once. The timer will actuate and,
when the time cycle is
completed, the upper platen will
rise automatically (timer is preset
at factory for six (6) seconds, but
this is easily changed by
following the upcoming
instructions.)
9. Remove the crust, place on a
disc, screen, pan or peel, add
toppings and bake.

Preventative Maintenance Suggestions
The Doughpro DP machines are
relatively maintenance free. For a long
and trouble-free life, the following
preventative maintenance should be
followed:
Daily Care:
1. Platens: Turn your machine off
and allow to cool down before
attempting to clean. These
platens should only be cleaned
with mild soap and warm water
then wiped off with a clean, soft
cloth or soft sponge. Never use
steel wool or harsh abrasives or
you will cause costly damage.
2. All other exterior surfaces:
Here again a daily wipe down
with mild soap and warm water
will do the job quite nicely.
Never use steel wool or harsh
abrasives or you will cause
costly damage.
Service Problems:
-4- DP 2/04
Contact our factory or approved service
agency (800) 624-6717 (U.S. only).
Note: When contacting factory for
information, parts or service
instructions, it is of the utmost
importance that the serial number of the
machine be provided. This number can
be found on the serial plate located on
the rear of the machine.

Check voltage on the secondary side
of the Transformer. If you read
12VDC then you are receiving voltage
to the Controller.
Replace Controller. Controller

on Digital Controller, nothing
happens.
The tactile buttons under the overlay
may be not close enough to activate.
Same goes if the buttons are already
pressed by overlay without

Press does not close when pressing
the two, green, start buttons
Did not simultaneously press the start
buttons exactly at the same time
Try pressing both buttons eactly at
the same time. This is a anti-tiedown safety feature.

The Lower Platen switch mounted on
the base is not in contact to complete
circuit
Make sure the roller plunger comes
into contact (clicking noise). This is
also a safety feature that both
platens are aligned before
Heater Platen overheating
If the Relay (depending the year of
the model) on the coil side are
receiving 12vdc indicates the
Controller is functioning properly. On
the switching side of the relay, is
there 120 vac going to the heater in
question . If there is no voltage on
the to the switching side of the relay
to the heaters, the Relay is not
working properly
Replace Relay If the Controller's
heat-on LED is not lit indicating the
controller is working properly.
55
Power is on but hear a leaking of air
under the lower platen / Ram
casting while Press is idle.
The O'rings are warn allowing the air
to pass through the cylinder. This
occurs when the cylinder walls looses
it's lubrication due to excessive water
generated by poorly maintained
compressor or undersized
compressor generating heat thus
generating water. Be sure to drain
captured water from compressor
tank on a regular basis.
The cylinder needs orings, gasket
and new cylinder grease. Request
instruction sheet and need to order
P/N 110033 for the kit.
___
After activation Lower Platen and
when cycle is complete, the Lower
Platen either is very slow coming
down or doesn’t go up or down at
all.
The Mufflers on the Solenoid Valve
maybe dirty and now allowing alr
from passing though. This occurs
when excess water is passing from
the compressor to the press. If this
doesn't correct the problem. You
may need to replace the solenoid
valve.
Replace both Solenoid Valve
mufflers.
A5.2
Both Upper and Lower Platen not
aligned when activating. You may
experience a shifting of the platens
when coming into contact, or
striking noise.
Upper and Lower Platen misaligned.
On the left side of the Post Collar
(#35) are back- to-back set screws.
Remove the first locking set screw.
Adjust stopping set screw to align
platen (*IMPORTANT* must reduce
air pressure to a minimum as not to
damaging closing platens). After
alignment is complete, re-install
locking set screw as not to move the
alignment set screw.
