DANGER:
WARNING:
NOTICE:
NOTICE:
THIS APPLIANCE MUST BE GROUNDED AT THE TERMINAL PROVIDED. FAILURE TO GROUND THE APPLIANCE COULD RESULT IN ELECTROCUTION AND DEATH.
INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT. UNIT MUST BE INSTALLED IN ACCORDANCE WITH ALL APPLICABLE CODES.
The data plate is located above the control panel behind the screen mesh. The oven voltage, wattage, serial number, wire size, and clearance specifications are on the data plate. This information should be carefully read and understood before proceeding with the installation.
The installation of any components such as a vent hood, grease extractors, fire extinguisher systems, must conform to their applicable National, State and locally recognized installation standards.
5.1 Installing the Legs
Legs are available for both the single and double deck installations. Single deck installations require a 27 inch leg. Double deck installations require 6 inch legs or casters.
To install the 27 inch legs, place some cardboard on the floor and gently tip the oven onto its back. Fasten two legs to the oven's front corners using the four 5/16 inch bolts provided in the leg kit. Lift the oven onto its front legs and block the back up using one of the 27 inch legs set upside down in the center rear of the oven body. Install the last 27 inch leg onto the oven body on the control side rear. Gently lift the oven rear, remove the leg set to support the oven center and install it on the last rear corner.
To install the 6 inch legs or casters, attach the leg or caster to the leg supports supplied in the oven by following the instructions in the box, then attach the leg support to the oven.
The adjustable feet on the bottom of each leg may be screwed in or out as necessary to level the oven.
A torpedo level placed on an oven rack will assist in leveling the oven.

5. INSTALLATION CONT’D
5.2 Stacking the Ovens
Remove all the plug buttons from the top of the lower oven. Remove the stacking kit from the oven compartment of one oven and install the 1 1/4
inch plastic bushing into the top of the lower oven. Tip the top oven backwards and install two 3/8 inch socket head bolts, found in the
stacking kit, into the two front leg holes that match the holes in the top of the lower oven. Install the socket head bolts with the heads of the bolt pointing away from the oven.
Lift the top oven and gently set on top of the lower oven so that the heads of the socket head bolts nest into the holes in the top of the lower oven.
5.3 Electrical Connection
The electrical service entrance is provided by a 1 1/4 inch knockout in the bottom right front corner of each oven, or at the oven back directly behind the control compartment. Grounding lugs are provided at both the front and rear service entrances.
The 208/240 volt oven is a dual voltage oven and is shipped from the factory as 208 volt. The oven must be field converted to operate on a 240 volt power supply.
To convert the oven to 240 volt, remove the jumper wire located on a terminal strip located inside the lower portion to the control compartment.
With 480 volt installations check to be sure that the motor rotates in a clockwise direction as viewed from the front of the oven.
To reverse the motor rotation, switch any two incoming power supply leads and recheck the rotation.
Supply wire size must be large enough to carry the amperage load for the number of ovens being installed. Wire size information can be found on the oven DATA PLATE.
This oven can be installed on both single and three phase supplies and is shipped from the factory for three phase.
To phase the oven to match the power supply, follow the charts on page 10 for proper wire size and grouping.
5.4 Clearances
Standard minimum clearance from
combustible
construction is as follows:
2 inches from sides 4 inches from back 6 inches from floor

6. INITIAL START UP
6.1 PRE-POWER ON
After the oven is installed and connected to power, prior to turning on, verify the following:
The doors open and close freely.
All five racks are in the oven correctly.
All packing materials have been removed from the inside of the oven.
6.2 POWER ON
When the oven is first turned on the display will read “Preheat”. The oven will begin to heat up at this point. When the oven reaches the correct temperature for the product selected, the display will read “Ready”.
Once the oven has reached it’s programmed temperature, select the shelf position you would like to cook on, press shelf button once for “C” product, twice for “P” product, or three times for “E” product.

During the first few hours of operation you may notice a small amount of smoke coming off the oven, and a faint odor from the smoke. This is normal for a new oven and
will disappear after the first few hours of use
.

7. OPERATION
7.1 GENERAL
CAUTION:
CAUTION:
Convection ovens constantly circulate air over and around the product. This strips away the thin layer of moisture and cool air from around the product allowing heat to penetrate more quickly.
Cooking times can be shortened. Check the product near the end of the initial cooking cycle by turning on the oven
light and looking through the oven door windows. Do not open the oven doors during baking, as this will change the baking
characteristics of the oven. Load each shelf evenly. Spaces should be maintained equally between the pan and
oven walls, front and back.
7.2 Control Panel
The control panel consists of the following items. Detailed operational descriptions are given later in this section.
ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM COMBUSTIBLE MATERIALS.
KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.

9. MAINTENANCE & CLEANING
9.1 Cleaning
WARNING:
CAUTION:
Always start with a cold oven.
The stainless interiors can easily be cleaned using most domestic or commercial oven
cleaners. Always follow the cleaner manufacturer's instructions when using any cleaner.
Care should be taken to prevent caustic cleaning compounds from coming in contact
with the blower wheel. The oven racks and rack slides may be cleaned by removing them from the oven and
soaking them in a solution of ammonia and water.
KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.
MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN TO WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD AND PROTECTIVE CLOTHING. CAREFULLY READ THE WARNING AND FOLLOW THE DIRECTIONS ON THE LABEL OF THE CLEANER TO BE USED.
The stainless steel door liners and oven front should normally be cleaned with a soap
and water solution. Discoloration or heat tint may be removed with any of the following cleaners: Penny
Brite, Copper Brite, Du-Bois Temp, or Past Nu-Steel. Always apply these cleaners when the oven is cold and rub in the direction of the
metal's grain.
