LOCAL AND NATIONAL CODES MUST BE FOLLOWED WHEN INSTALLING THE VENTILATION SYSTEM. ANY APPLICABLE LOCAL AND NATIONAL CODES SUPERSEDE THE RECOMMENDATIONS SHOWN IN THIS MANUAL. IMPORTANT ENGLISH Where national or local codes require the installation of fire suppression equipment or other supplementary equipment, DO NOT mount the equipment directly to the oven.
SECTION 2 - INSTALLATION III. ASSEMBLY A. Figure 2-3 - Exploded View, Oven Stand Stacking 1. Remove the casters (pre-attached to each oven cavity) from the upper ovens. 2. Stack the oven cavities. If necessary, refer to the Installation Manual for Model PS310/360 Ovens (Middleby P/N 882100025). B. Stands ENGLISH If the installation will include upper ovens mounted atop lower ovens: Attachment plates inc.
SECTION 2 - INSTALLATION V. TANDEM OVEN ASSEMBLY NOTE For non-tandem oven installations, skip ahead to Section VI, Conveyor Installation. ENGLISH 1. Determine the proper position of the ovens by referring to Figure 2-7. Then, move the ovens to their approximate final locations. 2. Check that the top and bottom air finger retaining screws are present on all mating ends of the oven sections. See Figure 2-7. The screws prevent the air fingers from sliding in between the oven sections. 3.
SECTION 2 - INSTALLATION Insert three of the supplied 1/2 x 5 bolts through the holes in the frame of the right oven, pointing outward as shown in Figure 2-9. Then, slide the spacers into place on the bolts. Figure 2-9 - Bolts and Spacers ENGLISH 4. 2-1/2" x 2-1/2" (64x64mm) spacers 2-1/2" x 8" (64x203mm) spacers 5. Push the ovens together. Check that the mounting bolts, alignment plate, and sealing gasket are all properly aligned. See Figure 2-10. 6. Tighten all of the attaching bolts.
SECTION 2 - INSTALLATION VI. CONVEYOR INSTALLATION Figure 2-12 - Removing the Conveyor Drive Sprocket Refer to either Step A or Step B in this section, as appropriate, to install the conveyor and belt. A. Installing the Conveyor - All ovens EXCEPT Tandem models ENGLISH NOTE Split belt conveyors can only be installed from the end of the oven with the drive motor. Single-belt conveyor assemblies may be inserted into either end of the oven.
SECTION 2 - INSTALLATION Installing the Conveyor and Belt - Tandem oven models NOTE For non-tandem oven installations, skip ahead to Section VII, Final Assembly. 1. Insert the conveyor frame into the oven as follows: Figure 2-17 - Tandem Conveyor Installation Hinged end section Slide one hinged conveyor frame section into each end of the oven. The two sections butt against each other at the gap between the two oven sections. See Figure 2-17.
SECTION 2 - INSTALLATION VIII. ELECTRICAL SUPPLY (all ovens) ENGLISH CAUTION Before connecting incoming power to the oven, measure the voltage of each input leg to neutral. The expected voltage is approximately 120V. ANY voltage reading exceeding 130V indicates that the supply has a high leg. CONNECTING A HIGH LEG TO THE OVEN VOIDS ALL OVEN WARRANTIES. Connecting a high leg to the black lead of the oven can severely damage the ovens electrical and electronic components.
SECTION 2 - INSTALLATION IX. GAS SUPPLY (gas ovens only) CAUTION 1. The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressure in excess of 1/ 2 psi (3.45 kPa). WARNING: To prevent damage to the control valve regulator during initial turn- on of gas, it is very important to open the manual shutoff valve very slowly.

SECTION 3 - OPERATION III. QUICK REFERENCE: DIGITAL TEMPERATURE CONTROLLER ENGLISH "SP LOCK" Light Lights when the set point is locked out from changes. This setting can only be changed by service personnel. "HEAT ON" Light Lights when the burner is in operation. Note that on all ovens EXCEPT the PS360EWB, this light cycles on and off during normal operation. Display Shows the Set Point or the Actual Temperature in degrees Fahrenheit (F) or Celsius (C).
SECTION 3 - OPERATION SYMPTOM TROUBLESHOOTING PROBLEM SOLUTION The oven temperature exceeded 650°F (343°C), and the burner was automatically shut down. Follow the procedures under Daily Shutdown Procedures in this section to shut down the oven.
