SECTION 2 INSTALLATION III. VENTILATION SYSTEM The rate of air flow exhausted through the ventilation system may vary depending on the oven configuration and hood design. Consult the hood manufacturer or ventilation engineer for these specifications. IMPORTANT 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.
IV. THERMOCOUPLE INSTALLATION 1. Install the thermocouple sensing bulb into the correct hole in the rear of the oven, as shown in Figure 2-3. Thread lead into machinery compartment here Thread lead into machinery compartment here Use for conveyor Use for conveyor Figure 2-3 Thermocouple Installation Locations 2. Thread the thermocouple lead through the grommet and into the machinery compartment. 3. Remove the right-side access panel of the machinery compartment. 4.
V. ASSEMBLY Attachment plates inc. w/ upper oven A. OVEN STAND If the installation includes upper ovens mounted atop lower ovens, the ovens must be stacked before joining the tandem ovens together. If the installation includes ovens that are to be mounted on stands, assemble the ovens to the stands before joining the ovens together. An exploded view of the stand is shown in Figure 2-6. Figure 2-6 Exploded View Oven Stand B.
SECTION 2 INSTALLATION 3. Remove the rear axial cooling fans that are adjacent to the mating sides of the ovens. The fans may either be completely disconnected, or left attached by their wiring as shown in Figure 2-8. Mating surface of ovens (shown from lower rear) Wiring is still connected Figure 2-8 - Cooling Fan Removal 4. 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.
SECTION 2 INSTALLATION 7. Attach the front trim strip between the two ovens, as shown in Figure 2-11. Figure 2-11 - Trim Strip Installation 8. Replace the rear axial cooling fans. See Figure 2-8. 9. Perform one of the following, as appropriate: Trim strip For PS360/360WB Tandem and Double Tandem installations, skip ahead to Part D, INSTALLING THE CONVEYOR FRAME AND BELT (Page 2-9).
SECTION 2 INSTALLATION 2. Align the two center ovens so that they are level and 20 (508mm) apart. Then, attach the two angled support brackets between the two center ovens, as shown in Figures 2-14 and 2-15. Figure 2-14 Support Brackets, Lower Oven Note that a LOWER OVEN uses different support brackets for the front and rear, while an UPPER OVEN uses identical brackets on the front and rear.
SECTION 2 INSTALLATION D. INSTALLING THE CONVEYOR FRAME AND BELT FOR ALL TYPES OF OVENS, ENSURE THAT THE DRIVE SECTION/END OF THE CONVEYOR FRAME IS PLACED ON THE SAME END OF THE OVEN AS THE CONVEYOR DRIVE MOTOR. 1. Insert the conveyor frame into the oven as follows: For a TANDEM or DOUBLE TANDEM oven, 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 2-18.
SECTION 2 INSTALLATION 2. Slide the conveyor belt through the support rods underneath the frame, and thread it through the oven. Then, reach through the oven window and pull the free end of the belt through the oven so that it lies atop the conveyor frame. Direction of travel After the belt has been pulled through the oven, check the following: The conveyor belt links must be oriented as shown in Figure 2-21. The smooth side of the conveyor belt must face UP. 3. Connect the inside master links.
SECTION 2 INSTALLATION 5. For a TANDEM, DOUBLE TANDEM, or TRI TANDEM oven installation, skip ahead to Step 9. For a QUAD TANDEM oven installation, continue on to Step 6. Latches 6. Slide the top transition panel into place. Then, slide the two transition side panels into place. See Figure 2-24. 7. If the four latches are not already attached to the side and top transition panels, attach them in place as shown in Figure 2-24. Latches 8.
SECTION 2 INSTALLATION VI. ELECTRICAL SUPPLY WARNING Authorized supplier personnel normally accomplish the connections for the ventilation system, electric supply, and gas supply, as arranged by the customer. Following these connections, the factory-authorized installer can perform the initial startup of the oven. NOTE: The electric supply installation must satisfy the requirements of the appropriate statutory authority, such as the National Electrical Code (NEC), ANSI/NFPA70, (U.S.A.
SECTION 2 INSTALLATION VII.GAS SUPPLY A. CONNECTION CAUTION DURING PRESSURE TESTING NOTE ONE OF THE FOLLOWING: 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). Check the ovens gas supply requirements before making the gas utility connection.
SECTION 2 INSTALLATION Certain safety code requirements exist for the installation of gas ovens; refer to the beginning of Section 2 for a list of the installation standards. In addition, because the oven is equipped with casters, the gas line connection shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (in U.S.A.), or, if applicable, Connectors for Movable Gas Appliances, CAN/CGA-6.
SECTION 3 OPERATION SECTION 3 OPERATION IMPORTANT THESE OVENS ARE INTENDED FOR PROFESSIONAL USE ONLY. THE OVENS MAY ONLY BE OPERATED BY QUALIFIED PERSONNEL. I.

SECTION 3 OPERATION II. NORMAL OPERATION - STEP-BY-STEP 6. Turn the HEAT switch to the ON position, and wait for the HEAT ON light to turn on. A. DAILY STARTUP PROCEDURE 1. Check that the circuit breaker/fused disconnect is in the on position. If the oven is equipped with a window, check that the window is closed. , wait for 2. Turn the BLOWER switch to the ON position. 7. Wait for the oven to heat to the setpoint temperature. Higher setpoint temperatures will require a longer wait.
SECTION 3 OPERATION III. QUICK REFERENCE: CALCULATING THE BAKE TIME Tandem and Double Tandem ovens display the bake time in minutes and seconds. Tri Tandem and Quad Tandem ovens, however, show a DC voltage value that corresponds to the speed of the conveyor drive motor. To calculate the bake time in minutes and seconds, perform the following procedure. With the conveyor running, place a product at the entrance end of the conveyor, as shown in Figure 32. Begin timing with a stopwatch.
SECTION 3 OPERATION V. QUICK REFERENCE: TROUBLESHOOTING SYMPTOM PROBLEM light is lit, food product is undercooked The oven temperature exceeded 650°F (343°C), and the burner was automatically shut down. Follow the procedures under DAILY SHUTDOWN PROCEDURES to shut down the oven. Contact your Middleby Marshall Authorized Service Agent to determine and correct the cause of the condition to prevent damage to the oven. Electrical power may not be reaching the oven, or the controls may be set incorrectly.
SECTION 4 MAINTENANCE SECTION 4 MAINTENANCE WARNING Before ANY cleaning or servicing of the oven, perform the following procedure: 1. Switch off the oven and allow it to cool. Do NOT service the oven while it is warm. 2. Turn off the electric supply circuit breaker(s) and disconnect the electric supply to the oven. 3. If it is necessary to move the oven for cleaning or servicing, disconnect the gas supply connection before moving the oven. When all cleaning and servicing is complete: 1.
