Product Overview

Conveyor ovens are utilized in commercial restaurants for continuous and consistent cooking of products like pizza, chicken wings, and sandwiches. The oven features a chamber with fans, electric heating elements, and air guide boxes that direct hot air. A conveyor belt transports food through the chamber for cooking.

Key Features

• Easy to clean
• Stainless steel construction
• Programmable touchscreen controller
• Stackable design
• Integrated air impingement

Certifications: ETL SANITATION LISTED (Intertek 5013357, Conforms to NSF/ANSI 4), ETL LISTED (Intertek 5013357, Conforms to UL STD. 197, Conforms to UL STD. 710B)

Safety Precautions

CAUTION: Failure to comply with operating instructions may lead to hazards, unsafe practices, injury, and damage to product and property.

NOTICE: Installation must comply with all local codes, which are considered the "Authority Having Jurisdiction" per NFPA96. This product is intended for commercial use only.

WARNING: Do not store or use flammable vapors or liquids near the equipment. Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read all instructions before servicing. Retain this manual for future reference.

ELECTRICAL WARNING: Equipment lines must be reliably grounded. Equipotential terminals are recommended. Installation of a leakage protector by qualified personnel is also recommended.

Specifications

NOTE: Maintain at least 24" of space between units if other cooking equipment is present.

NOTE: Each oven requires its own electrical connection.

NOTE: Voltage cannot be converted. Purchase a unit with the correct voltage.

NOTE: Units are wired for 1-Phase but can be converted to 3-Phase, reducing amperage to 15A.

Installation Instructions

Note: Installation must be performed by a licensed service technician.

1. Location:
   • Ventless Models: Choose a countertop location with adequate clearance on all sides (refer to specification table for minimum operational clearances). Proper ventilation is crucial for safe and optimal performance.
   • Non-Ventless Models: Choose a location under a ventilation hood with adequate clearance on all sides. Installation must comply with all applicable local and national codes.
2. Impingement Plates: Connect impingement plates to the air outlet within the chamber. Ensure top impingement fingers face down and bottom fingers face up. Secure the top assembly to the left with the hook. [Diagram showing impingement plate connection]
3. Conveyor Belt: Slide the conveyor belt through the chamber from right to left. Secure the belt by pressing the spring to lock the drive shaft into the groove. [Diagram showing conveyor belt installation]
4. Preparation: Ensure crumb trays are pushed in and extension plates are attached to both ends of the conveyor belt before operation. [Diagram showing crumb tray and extension plate placement]

Electrical Connection

1. Verify that the voltage on the unit's nameplate matches the supplied voltage.
2. Installation must adhere to national and local codes and be performed by a licensed technician.
3. The unit must be electrically grounded according to all local and national codes (e.g., ANSI/NFPA 70 in the USA).

Terminal Block Wiring Change

1. Locate the incoming power terminal block in the control box.
2. Remove the jumper wire connecting L1 and L2.
3. Remove the jumper wire connecting L2 and L3 (retain this wire).
4. Use the retained jumper wire to connect L1 and N terminals.
5. Connect one incoming power leg to L1.
6. Connect the second incoming power leg to L2.
7. Connect the third incoming power leg to L3.
8. Verify all screws are tight and wires are secure. Control box wiring is complete.

Heating Element Wiring Change

1. Access wire connections on the element by removing the back panel.
2. Remove wire #7 and cap it with a high-temperature porcelain nut. Secure with high-temperature fiberglass tape.
3. Remove jumper wires from connections 3 and 1, and connections 1 and 2 on the heating element.
4. Use provided jumpers to connect terminals 3 and 1, 2 and 3, and 1 and 2 on the element as shown in the diagram.

Verification: Run the oven and use an amperage clamp on each incoming power leg to ensure all legs draw amperage during the heating cycle.

Oven Stacking Instructions

Note: Requires two like ovens. Stacking should be performed by an authorized technician.

Figure 1: Use a wrench to remove the 4 feet from the upper unit and a screwdriver to remove the bottom plate on the flue. [Diagram illustrating foot and plate removal]

Figure 2: Each unit has 4 protrusions on the bottom and 4 depressions on the top. Align the protrusions of the top unit with the depressions of the bottom unit during stacking. [Diagram illustrating alignment of protrusions and depressions]

Figure 3: Place the top unit onto the bottom unit. Embed the upper flue into the lower flue. Install the connecting plate and tighten the cover with a nut to secure the ovens together. [Diagram illustrating final stacked assembly]

Operating Instructions

Controller Location and Function

The control panel includes a Computer Board, an Emergency Power Switch, and a MAIN POWER SWITCH.

WARNING: Do not turn off the unit using the emergency power switch during normal operation without completing the standard cool-down process. This can cause overheating and internal damage.

Power On

1. Press the "Emergency Power Switch" to turn on the unit and activate the touchscreen.
2. Press the "Power On" button to enter the "Free Mode" interface.

Free Mode Interface: Displays current time, date, cooking time, and temperature. Allows adjustment of cooking time and temperature.

KEY:

• Cooking time setting: Click the time window to set cooking time.
• Cooking temp setting: Click the temperature window to set cooking temperature.
• Preheating status: Indicates the oven is preheating.
• Preheating Completed: Indicates preheating is finished.
• Cooling Down: Indicates the oven is in the cool-down process.

NOTE: If the temperature is not displayed, press "Preheating Status" to view the live temperature for 5 seconds.

Shut Down

To shut down, long press "Shut Down" for 3 seconds. If the temperature exceeds 195°F, the unit will automatically enter cool-down mode before shutting down.

WARNING: Do not use the emergency power switch during automatic cool-down to prevent high-temperature damage.

Menu Mode

5. Use a hard nylon brush to clean the conveyor belt.
6. Remove, clean, and replace the crumb pan.

CAUTION: If the cooling fan malfunctions, replace it immediately. Operating the oven without sufficient cooling can damage internal parts.

Monthly Cleaning

1. Ensure the oven is powered off and unplugged. Do not clean until cooled.
2. Remove crumb trays, extension plates, left and right baffles, and the conveyor assembly.
3. Note the installation position of each impingement finger assembly and shutter for correct reassembly.
4. Number the three components of each impingement finger assembly before disassembly to aid reassembly.
5. Clean the air guide box components and the oven interior with a damp cloth.
6. Reassemble the impingement finger assembly according to the numbered positions.
7. Reinstall the left and right baffles.
8. Reinstall the conveyor chain assembly.
9. Check conveyor belt tension (should pull up 2-3" / 50-70mm). Adjust tension using the belt tightness adjusting screws if necessary.
10. Reinstall the crumb trays.
