V. FINAL ASSEMBLY

1.Refer to Figure 2-12 to determine the correct locations of the crumb trays.

2.Install the crumb trays underneath the conveyor as shown in Figure 2-12. First, place the inside edge of the tray onto the retainer. Then, swing the outside edge of the tray up and into place.

3.Press the conveyor end stop and rear stop down over the edge of the conveyor frame.

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.); the Canadian Electrical Code, CSA C22.2; the Australian Code AG601; or other applicable regulations.

NOTE: The electric supply connection must meet all national and local electrical code requirements.

Check the oven serial plate before making any electric supply connections. Electric supply connections must agree with data on the oven serial plate.

A fused disconnect switch or a main circuit breaker (customer furnished) MUST be installed in the electric supply line for each oven cavity. It is recommended that this switch/circuit breaker have lockout/tagout capability.

The supply conductors must be of the size and material (cop- per) recommended. Refer to the wiring diagram inside the machinery compartment of the oven. Electrical specifications are also listed on the oven's serial plate.

The oven requires a ground connection to the oven ground screw located in the electrical junction box. (The box is shown in Figure 2-13.) If necessary, have the electrician supply the ground wire. Do NOT use the wiring conduit or other piping for ground connections!

All electric supply connections are made via the electrical junction box on the rear of the oven, shown in Figure 2-13. The power lines then connect to the oven circuits through safety switches located inside the machinery compartment and each blower motor compartment. These switches interrupt electric power to the oven when the Machinery Compartment Access Panel is opened, OR when either of the rear shrouds is removed.

Refer to the wiring diagram inside the machinery compartment of the oven to determine the correct connections for the electrical supply lines. Connect the supply as indicated on the wiring diagram. Be sure to connect the electrical supply ground wire to the oven ground screw located in the junction box on the rear of the oven.

VII. GAS SUPPLY

CAUTION

DURINGPRESSURETESTINGNOTEONEOFTHEFOLLOWING:

1.The oven and its individual shutoff valve must be discon- nected 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).

2.The oven must be isolated from the gas supply piping system by closing its individual manual shutoff valve dur- ing any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psi (3.45 kPa).

3.If incoming pressure is over 14” W.C. (35mbar), a sepa- rate regulator MUST be installed in the line BEFORE the individual shutoff valve for the oven.

WARNING: To prevent damage to the control valve regula- tor during initial turn- on of gas, it is very important to open the manual shutoff valve very slowly.

After the initial gas turn-on, the manual shutoff valve must remain open except during pressure testing as outlined in the above steps or when necessary during service main- tenance.
