UNCRATING AND INSPECTION

Unpack the unit and components from the shipping container. Remove all visible packing materials including those that may be inside the baking chamber. If damage is discovered, file a claim immediately with the carrier that handled the shipment.

ASSEMBLY AND INSTALLATION

The equipment is shipped fully assembled and ready to plug into a matching outlet specified for its specific voltage and amperage rating. Removal or replacement of the power cord and plug will VOID the warranty. For assistance, contact the Belleco, Inc. Service Team at 1-877-854-

8006. Please refer to the appropriate schematic at the rear of this manual for plug configurations. Consult with a licensed electrician prior to installation. Do not operate this equipment without the crumb trays properly installed as this may cause overheating and loss of productivity.

CAUTION – During installation: Do not place on surfaces or near walls, partitions or kitchen furniture and the like – unless they are made of non-combustible material or clad with non-combustible heat-insulating material, and pay attention to fire prevention regulations.

CAUTION – To reduce the risk of fire, the appliance is to be installed in non-combustible surroundings only, with no combustible material within 18 inches of the sides, front, or rear of the appliance or within 40 inches above the appliance. Food may burn. Therefore equipment must not be used near or below curtains and other combustible materials.

They must be watched.

ELECTRICAL INSTALLATION

WARNING – Disconnect the unit from its power source before installing or removing any parts.

WARNING – Check with your local power company or licensed electrician before installation to determine the actual voltage at the outlet. For a unit rated 208 volts, never plug it into 240 volts as serious overheating and damage could occur. For a unit rated

240 volts, never plug it into 208 volts as the lower voltage will greatly reduce the productivity of the unit.

WARNING – NEVER operate any piece of equipment without proper GROUND connection. Improper grounding may result in serious personal injury or could be fatal!

Suggested Dough Handling Procedures

• Remove frozen dough balls from their wrapper and place into a proofing box or on a sheet pan. (Some dough manufacturers provide different techniques for their dough that may not agree with the following therefore, some trials may be required)

• Place the dough balls a few inches apart, lightly spray release over the dough balls then cover with a layer of freezer paper. Refrigerate over night. Only remove enough products from the sheet pan to accommodate what you will require for a few hours.

• Roll the ball flat (onto a light sprinkling of flower, cornmeal or pizza crisp) starting from the center and working your way to the outer edges. Make sure you turn the dough as you work towards the outer edges to maintain a round configuration. Then, use either a rolling pin or dough press or dough sheeter to form the dough to the desired size and thickness.

• Place the flattened shell onto a screen or a seasoned pizza pan. (Shiny aluminum pans may reflect heat away from the pizza preventing browning) Dock it, sauce it, and cheese it. Remember to spread the sauce from the center to the outer edges of your crust to ensure a uniformed thickness of sauce. Leave an inch of space to the outer edge of the crust to enable browning (sauce too close to the edge prevents browning).

• When adding vegetables with high moisture contents remember to spread them out and to avoid over saturation of these toppings. Excessive high moisture toppings will prevent baking in the surrounding areas until ALL the moisture has been evaporated.

• Place the prepared pizza at the entry end of the oven and adjust as required. A consistent product going in will result in consistent product coming out.

REECOMENDED BAKING BANS:

FOR OPTIMAL BAKING PERFORMANCE THE USE OF A SEASONED/ BLACKEND PAN OR

SCREEN IS RECOMMENDED.

OPERTIONS MANUAL MGD-18 Troubleshooting Guide

Symptom

Oven will not turn on, display is blank

Display will not change from WARMING to REDY

Display changes from WARMING to

HEATING and does not read REDY

Cause

No power at outlet

Master On/Off switch at rear of unit in the Off position.

30 amp fuse is blown.

Temperature probe in zone is not responding

Possible burned out heater tube in zone.

Loose connection at terminal block (see wire diagram)

Loose connection at heat relay or defective relay

One heat zone may not be on.

One or more Temperature settings may be set too high

Supplied voltage to oven may be too low (i.e. 240 volt oven running on 208 volts)

Temperature threshold has been reached.

If zone temperatures are set above 455° (F) the oven changes to heating mode as the elements are now at full intensity and will not cycle on and off.
