DESCRIPTION/SPECIFICATIONS
Description
The Oven is a stainless steel, electric, forced air, (convection), oven with steam injection
capabilities. This oven offers consistent baking at all rack levels due to the careful
positioning of the heating and air circulation systems.
In addition to the above, this oven also offers many other features. It is well insulated
with a high quality asbestos free insulation. It is compact, attractive, quiet, and is
easily maintained. Should electrical servicing ever be required the electrical
components are readily accessible by removing the side or back panels.
The lighted, tempered glass door with its high temperature seal allows a full view of the
trays in the oven during baking.
The oven computer allows you to bake two items at once which makes the oven more
productive. It also has one of the fastest temperature recoveries on the market allowing
the oven to be turned off during non-peak hours, thus saving energy.
The oven has many protective features such as not allowing heating of the elements
when the door is open. Other features are resettable thermal overloads on the motors, a
high-limit thermostat, and a magnetic circuit breaker on the control circuit.
The computer allows easy selection of baking programs. The programs combine
precise control of the pre-heat temperature, baking temperature, time, pre-alarm, steam,
and damper control. This allows precise baking by even inexperienced individuals.

INSTALLATION / SETUP
Inspection
Before excepting delivery inspect the carton and machine for damage. Note any
damage found on the shipping documents. Remember shipping damage is not
by your warranty, and is the responsibility of the carrier. Also report the damage to the
dealer from which the oven was purchased for further direction and assistant in filing a
claim with the carrier.
Location Selection
Select a location where the oven will be used. The oven must be set on a flat level
surface. It should have a grounded power supply of the same rating as shown on the
nameplate located on the rear of the oven and this power supply must be capable of
carrying the load that the oven will put on it (See “Electrical Connection” below). The
oven must also be placed near both a water supply and an area where the oven can be
properly vented (See “Water Connection” and “Venting” below).
Ovens with casters should be placed so that they have a minimum of two inches on
each side and a minimum of four inches in the rear of the oven to provide for proper
venting, water, and electrical connections.
Ovens without casters should be placed so that there is a minimum of two inches on all
sides, except for the side with the electrical panel, (right side), which should have a
minimum of twelve inches. The rear of an oven without casters should be a minimum of
four inches away from adjacent surfaces to allow room for the electrical, water and
venting connections.
Sealing Oven to Mounting Surface

CAUTION
MAKE SURE THAT THE MOUNTING SURFACE IS ABLE TO SUPPORT THE
WEIGHT OF THE OVEN WHICH IS APPROXIMATELY 500 POUNDS PLUS AN
ADEQUATE SAFETY FACTOR BEFORE PLACING IT ON THE SURFACE.
The oven must be
For the purpose of sealing the unit a tube of NSF/FDA approved silicone sealant has
been provided with your unit. Apply, to the surface that the oven will rest on, a
continuous bead of sealant approximately 1/2 inch in from each of the four sides of the
oven. After the oven has been placed over this bead apply a second generous
continuous bead at the joint where the oven contacts the mounting surface thus totally
sealing the bottom of the oven to that surface.
0690S20042 3-1
sealed to the mounting surface to comply with local sanitation codes.
Oven Setup
Ovens may be mounted to a fixed surface, attached to an “Oliver” oven rack with casters
or stacked. For associated mounting heights for the above options see figure 3.0 on
page 2-2.
CAUTION
USE CARE WHENEVER MOVING OVENS MOUNTED ON RACKS AS THEY ARE
TOP HEAVY AND PRESENT A TIPPING HAZARD.
Ovens attached to “Oliver” oven racks must be
Stacked ovens should be setup as shown on page 2-2 being sure that the alignment
pins on the top of the lower oven are securely positioned into the holes in the base of the
upper oven.
After the Oven has been mounted to a surface, attached to a rack, or stacked, remove
the shipping bracket, which secures the door. To remove the shipping bracket, remove
the two screws from the top of the door with a screwdriver and open the door. Replace
these screws and tighten securely. To remove the shipping bracket from the front of the
oven liner, remove the two hex head screws with a wrench. The bracket and screws
may be discarded. Replace the removed hex head screws with the two screws provided
in a bag taped to the floor of the oven chamber and tighten securely.

securely fixed to the rack with bolts.
WARNING
THE OVEN MUST BE CONNECTED TO A PROPERLY GROUNDED ELECTRICAL
SOURCE OF THE SAME RATING AS THE MACHINE. FAILURE COULD RESULT IN
AN ELECTRICAL SHOCK WHICH MAY CAUSE INJURY OR DEATH.
WARNING
ALL WIRING AND ELECTRICAL REPAIRS SHOULD BE DONE BY A QUALIFIED
ELECTRICIAN. FAILURE TO DO SO MAY CAUSE SERIOUS INJURY OR DEATH.
CAUTION
SPECIAL HEAVY DUTY ELECTRICAL SERVICES AND WALL DISCONNECTS
MUST BE PROVIDED FOR SAFE OPERATION OF THE OVEN.
The following service requirements are recommended, dependent on the voltage of the
unit you have purchased. Your oven’s requirements can be found on the nameplate
attached to its rear surface.
0690S20042 3-2
Electrical Connection (continued)
For voltages other than those shown below please contact the factory. Check the
voltage at the disconnect before proceeding to the next step.
480 Volts = 30 Amp service
375 Volts = 30 Amp service
240 Volts = 60 Amp service
208 Volts = 60 Amp service
The oven is shipped from the factory with a power cord, which does not include a plug.
The power cord should be wired to a disconnect enclosure which is accessible from the
oven work area, leave at least two feet of slack so that access can be gained to the
ovens back and right side. A plug may be used between the disconnect enclosure and
the oven instead of hard wiring as described above. This makes sliding the oven out for
service more convenient. Whatever method is used the oven should be wired in a
manner which would conform to the U.S. “National Electric Code”.
CAUTION
FANS MUST ROTATE IN THE CLOCKWISE DIRECTION FOR PROPER AIRFLOW.
IMPROPER DIRECTION MAY CAUSE UNEVEN BAKES AND LONGER BAKING TIMES.
Check fan rotation for clockwise direction. After the oven has been “Set Up” and
connected to the electrical service do the following to check the rotation of the fans. At
the lower right hand corner of the front surface of the oven you will find a small
rectangular panel held in place with two thumb screws. Removing these screws and the
panel they secure will expose the “Manual” controls of the oven. Use the following
sequence to start the oven to check fan rotation direction:
• Switch the oven to manual mode.
• Turn the main power switch on, (green button above
oven should start and fan rotation can now be checked.
• Once complete, turn the main power switch off, (red button above
controls), return the oven to automatic mode and replace the cover.
If the rotation is incorrect remove and interchange any two of the three incoming power
leads (red, white and black), at the plug or disconnect enclosure and retest.

0690S20042 3-3
Water Connection
All water connections must comply with the basic plumbing code of the Building Officials
and Code Service Sanitation Manual of the Food and Drug Administration (FDA)
CAUTION
WATER PRESSURES GREATER THEN RECOMMENDED CAN CAUSE EXCESS
WATER TO ENTER THE OVEN CAUSING WATER TO LEAK AT THE DOOR AND
ALSO CAUSE THE TEMPERATURE TO DROP SEVERELY AFFECTING THE BAKE.
USE A PRESSURE REGULATOR TO REGULATE THE PRESSURE.
The oven must be connected to a water supply to enable the oven to produce steam for
baking. As shipped from the factory the oven will have a solenoid valve at the back
center of the oven, (See figure 3.0 page 2-2). This valve has an internal 1/4” NPT thread
for connection. Water pressure should be a maximum of 60 to 70 PSI and the water
must clean. Use a pressure regulator and a water strainer/filter to meet these
guidelines. Before making the water connection flush all lines and install the regulator
and filter. Remember solenoid failure and related problems caused by dirt may not be
covered by your warranty.
NOTE
HARD WATER LEAVES MINERAL DEPOSITS ON GLASS AND OTHER SURFACES
WHICH DETRACT FROM OVEN APPEARANCE.
The solenoid valve can be checked after “Set Up” and the “Electrical and Water
Connection” has been completed. At the lower right hand corner of the front surface of
the oven you will find a small rectangular panel held in place with two thumb screws.

• The water solenoid valve may have failed.
• The water pressure may be to low, the oven requires between 60-70 psi.
• The water spray nozzles inside the oven chamber which spray water into each of the
blower fans may be plugged, remove the nozzle assembly and clean.
• The nozzle assembly, which sprays water into the blower fans, is not vertical and is
not spraying the water directly into the fans as it should.
The Steam Will Not Stop /or Continuos Steam
It is normal for water to drip from the spray nozzles for several seconds after steaming,
however if it continues to drip or run, check the following.
• The water solenoid valve may be dirty and stuck open.
• The water solenoid valve may have failed.
0690S20046 6-3
Steam Is Leaking From the Door
It is normal for some steam to escape from the door during the steaming operation,
however, if excessive amounts escape you should check the following.
• The door seal may be damaged.
• The door may not be latching properly.
The Door Will Not Close
• Slamming the door too hard can cause it to bounce off of the seals, not allowing the
door time enough to latch properly.
• Sometimes after replacement of the door seals the strike may need to be reshimmed to generate the proper seal. Remember only a single shim should be
used, order shim kit number 690-0148K when replacing seals.
• Check for a worn or broken latch or strike.
• The Latch mounted to the door may be too far away from the strike. It may be
adjusted left to right.
One or both of The Blower Fans Will Not Run
• The oven liner may be rubbing on the fan preventing its rotation.
• A motor fuse may need to be replaced.
• The door switch may not be working.
• The fault/high limit lamp is on, see the trouble shooting suggestions for this area
above.
• The high limit switch has failed.
• A blower fan motor may have failed.
The Blower Fans Run Continuously
Other than when the oven is in “Cool Down” mode the blower fans should not run when
the door is open. Things which may make this happen are:
• A failure of the door switch.
• A blower fan motor contactor failure.
0690S20046 6-4
The Oven Is Overheating
This may be a normal condition experienced when the oven is empty. Normally the
oven’s program will attempt to correct temperature based on a full oven’s reqirements.
• A heat contactor may have failed.
• There is an error in your program, if it is a new program check that the temperature
was entered correctly.
• The oven may be out of calibration. See the Advanced setup Mode on page 6-6 to
find out how to re-calibrate the oven.
The Oven is Baking Unevenly
• A blower fan or fans are turning in the wrong direction.
• The oven may be out of calibration. See the Advanced setup Mode on page 6-6 to
find out how to re-calibrate the oven.
• The vent damper may be stuck open.
• One or more of the blower fans may not be turning. See page 6-4 possible causes
for this
• You may have low voltage at the power source.

MAINTENANCE
WARNING
NEVER ATTEMPT TO CLEAN OR SERVICE THIS OVEN UNTIL IT HAS BEEN
DISCONNECTED FROM THE POWER SUPPLY AND IS COOL TO THE TOUCH.
NOTE
REMEMBER A CLEAN OVEN WILL LAST LONGER AND WORK BETTER.
Cleaning
The outside of the oven should be cleaned daily by wiping it with a clean damp cloth or
by using any suitable stainless steel cleaner. A solution made up of a mild detergent
with water will normally be sufficient for routine cleaning of the interior of the oven.
When finished dry the surfaces with a clean cloth.
The glass door should be cleaned daily using normal glass cleaners.
For more difficult cleaning jobs such as where there are burned on or greasy deposits, or
heat tint, you should use an abrasive pad. Remember for best results always keep the
stainless steel shiny.
To simplify major cleanings the inner liner may be removed by first removing the nozzle
assembly in the back of the oven with an open end wrench, and then by removing the
eight slotted head screws which secure the liner. Six of these screws are in the front of
the oven while two additional screws are on the rear panel adjacent to the nozzle
assembly.
Clean the rear fan cover frequently to insure air circulation through the electrical
compartment. This will lessen the possibility of heat related electrical problems.
The heating elements themselves normally do not require cleaning.
Lubrication
Occasionally put a few drops of oil on the pivot points of the door. No other items
requires lubrication.
CAUTION
NEVER LUBRICATE THE MOTORS
