GENERAL DESCRIPTION

The Marshall High Speed Vertical Toaster produces a grilled effect on the cut side of sandwich buns. The buns are inserted at the top of the unit and are pressed against a heated grill surface, which is covered by a replaceable grill cover. The buns are discharged onto a product slide at the bottom of the unit. The system has separate heat controls for the bun crown, heel, and cut surface temperatures. These are safely located inside the secure cabinet thus eliminating unauthorized tampering with settings. This toaster is unmatched allowing operators to produce the hottest buns in the shortest time.

GENERAL SPECIFICATIONS Height: 21.125"

Width: 12.625" Depth: 18.875" Electrical: 208V Single Phase 20 Amps Special Note: If toaster is wired to a 240V single

phase supply, special adjustments are required, see note 1A under "INSTALLATION AND OPERATION."

Power Cord: 6 ft. 3 wire with ground, with NEMA

L14-30P Plug

Weight: 62 Ibs.

1. This toaster is shipped completely wired and ready to plug into a grounded NEMA L14 30R amp receptacle. (208 Volt Single Phase, 3 wire with ground circuit). Check receptacle for proper voltage and phase.

1A. Other voltages - some localities may only have 240 volts and a 208 volt machine has been

used. To compensate remove the control cabinet side cover WITH THE UNIT UNPLUGGED and turn the two temperatures switches that are pointer type knobs from a setting of 12 down to a setting of 9. DO NOT CONNECT HIGH LEG OF A 240 VOLT CIRCUIT TO TOASTER.

2. Place toaster on level metal surface.

3. Install product slide on the underside of the toaster. The product slide hangs on a rod located under the toaster and directs the buns out from under the toaster.

4. Check that the two lift off side covers are in place on the toaster. One is marked "Heel", which indicates the side of the toaster for inserting the bottom, or heel, of the bun.

INSTALLATION AND OPERATION

5. Check that the grill cover (Teflon) is installed over the contact platen. The Grill cover is installed from the top of the unit by lightly creasing it at the center, and directly hanging it on the contact platen. NOTE: THE NOSE GUARD SHOWN IN FIG 4, KEEPS THE GRILL COVER IN PLACE.

6. Connect the toaster to the power supply.

7. Turn on the conveyor switch on the toaster and check for free movement of the two conveyor belts.

8. Turn on the heat switch. Allow 15 minutes for the toaster to warm up before toasting buns.

9. After warm up, drop buns into the toaster at the top of the unit. 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 each other.

10. The toasted heel and crown will drop down onto the product slide together. Check the appearance of the toasted buns.
