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
CAUTION
TO QUALIFY FOR WARRANTY COVERAGE, INSTALLATION MUST BE COMPLETED BY
AN OLIVER PACKAGING & EQUIPMENT AUTHORIZED SERVICE DEALER.
Inspection
Before accepting delivery inspect the carton and machine for damage. Note any damage found
on the shipping documents. Remember shipping damage is not covered 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.
0690S20069 3-1
The oven must be sealed to the mounting surface to comply with local sanitation codes. 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.
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 securely fixed to the rack with bolts. 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.
Electrical Connection
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
0690S20069 3-2
SPECIAL HEAVY DUTY ELECTRICAL SERVICES AND WALL DISCONNECTS MUST BE
PROVIDED FOR SAFE OPERATION OF THE OVEN.
Electrical Connection (continued)
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.
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
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. Use the following
sequence to start the oven to check fan rotation direction:
· Turn the main power switch on, (green button). The oven should start and fan rotation
can now be checked.
· Once complete, turn the main power switch off, (red button)
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.

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.
