SIDE OF TOASTER WITHOUT FIRST TURNING OFF THE TOASTER AND UNPLUGGING THE CORD.

INSTALLATION

1. Place toaster on a level surface.

2. Check that all panels and covers are in place on the toaster.

3. Check that the toaster platen sheet is installed over the contact platens. The toaster platen sheet is installed by placing rods into arms of toaster. See Figure 4 .Make sure seam is against platens (facing top of toaster). USE ONLY MARSHALL APPROVED PLATEN SHEETS OR TOASTER WARRANTY IS VOID.

4. Check conveyor carriage making sure it is completely seated in saddles and on top pins.

5. Connect the toaster to the power supply.

6. Press and release the “I/O” button on the control. “Lo” will be displayed. Check for free movement of the conveyor belt.

7. Toaster is ready to use in approximately 15 minutes. Control will display “rdy”.

8. After warm up, insert buns into the top of the toaster. For proper operation, insert heels on the side of the toaster marked "Heel", and crown on the opposite side. THE CUT SIDES OF THE HEEL AND CROWN MUST FACE THE TOASTER PLATEN SHEET.

9. The toasted heel and crown will return to the toaster front together. Check the quality of the toasted buns.

10. Adjust the gap between the conveyor and the toaster heat platens using the two knobs on top of the toaster (see Figure 1 for knob locations). Both must be lowered at the same time. The knobs are labeled “HEEL” and “CROWN”. The height gauges in the front indicate whether you are raising or lowering the platens.

11. The Adjustment Range is .625” – 1.438”.
