INSTALLATION

These “C” Channel brackets are installed in the vertical plane using existing screws to support these ‘C” Channels using the upper and lower Key Hole openings in the ‘C’ Channels. The “C” Channels are identical and once installed will allow ample amounts of air through the cooling fan mounted on the rear side of the oven by keeping the oven away from the rear wall.

III.ELECTRICAL CONNECTION INFORMATION FOR PS520-SERIES OVENS.

WARNING

Authorized supplier personnel normally accomplish the connection for the ventilation system, electric supply, as arranged by the customer. Following these connections, the factory-authorized installer can perform the initial start-up of the oven.

Check the oven data plate (Figure 2-10) before making any electric supply connections. Electric supply connections must agree with data on the oven data plate.

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.

A fused disconnect switch or a main circuit breaker (customer supplied) MUST be installed in the electric supply line for each oven; it is recommended that this switch/circuit breaker have lockout/tagout capability. The electric supply connection must meet all national and local electrical code requirements. Copper is the recommended material for the electrical supply conductors.

IV. ELECTRIC SUPPLY FOR ELECTRICALLY HEATED OVENS

Power requirements for electrically heated ovens are usually 208-240VAC, 1-phase, 3 wire (2 ‘hot’, 1 ground), although ovens built for export can have power requirements of 380VAC and 480VAC. (These ovens have a 4-wire or 5-wire system.) A 1.5” (38mm) diameter cutout/hole in the back of the machinery compartment provides access for the electrical supply connections on 380V and 480V units. 208V and 240V units have a cord and plug. Using flexible cable(s) for the electrical power supply conductors requires a 2” (51mm) strain-relief fitting (not furnished) to enable safe access to the terminal block from which oven power is distributed.

The supply conductors must be of the size and material (copper) recommended to provide the current require; (refer to the data plate for the ampere specifications).

Typical specifications for each PS520-Series Oven are 208-240V, 1-phase, 3 wire, 8.3kW; this oven requires 50 ampere service. A PS520-Series Double Oven (Figure 1-2) installation would require two 50 ampere service connections, one for each oven; the 8.3kW power consumption also doubles for such an installation to 16.6kW.

The 208V, 230V or 240V AC electrically heated oven uses two legs of the supplied power to provide 208V, 230V or 240V AC power for the oven control circuitry
