INSTALLATION / SETUP
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).
Ovens mounted on other units 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 motor ventilation and electrical connection.
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 connection and
motor ventilation.
Sealing Oven to Mounting Surface
CAUTION
MAKE SURE THAT THE MOUNTING SURFACE IS ABLE TO SUPPORT THE WEIGHT
OF THE OVEN WHICH IS APPROXIMATELY 300 POUNDS PLUS AN ADEQUATE
SAFETY FACTOR BEFORE PLACING IT ON THE SURFACE.
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.

MODEL 688-N
0688S20004 3-2
Oven Setup
Ovens may be mounted to a fixed surface, attached to an “Oliver” oven rack with casters
or stacked on either a Oliver Model 690 Oven or and Oliver Model 695 Proofer. For
associated mounting heights for the above options see 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 units should be setup as shown on page 2-2 being sure that the alignment pins
on the top of the lower unit are securely positioned into the holes in the base of the upper
oven.
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
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.

MODEL 688-N
0688S20004 3-3
Electrical Connection (continued)
For voltages other than those shown below please contact the factory. Check the voltage
at the electrical disconnect before proceeding to the next step.
480 Volts = 20 Amp service
375 Volts = 20 Amp service
240 Volts = 30 Amp service
208 Volts = 30 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 blower motor should
start. Once started the fan rotation can 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.

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 door may be lifted off of the hinges and the inner liner may
be removed by removing the six slotted head screws which secure the liner. Four of
these screws are in the front of the oven while two additional screws are on the rear panel
above and below the fan opening.
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 require
lubrication.
CAUTION
NEVER LUBRICATE THE MOTORS
