NEMCO ROLL-A-GRILL 8027 (01) PDF Document

Before using your NEMCO ROLL-A-GRILL 8027, please follow these initial instructions:

1. Please read all instructions before using the machine.

2. Clean the machine thoroughly before and after every use, following the cleaning instructions provided.

3. This machine will be HOT during use and for a short time after it is turned off. Always BE CAREFUL.

1. Plug the electrical cord into a certified electrical outlet with a corresponding voltage rating as listed on the machine model labels. Units with two cords must be plugged into outlets on individual branch circuits.

2. There is one motor in units that have one on/off switch.

3. There are two motors in units that have two on/off switches. The left switch controls the rotation of the front set of rollers and the right switch controls the rotation of the rear set of rollers.

4. On units with two temperature controls, like the NEMCO ROLL-A-GRILL 8027, the left dial controls the front half of the rollers which are denoted by black bearings. The right dial controls the rear rollers which have white bearings.

5. For units with four temperature controls, they operate from left to right across the front panel:

• Switch #1 controls the heat in the front four rollers 1-4 which are designated by black bearings.

• Switch #2 controls the heat in the next four rollers 5-8 which are designated by white bearings.

• Switch #3 controls the heat in the next four rollers 9-12 which are designated by white bearings.

• Switch #4 controls the heat in the next four rollers 13-16 which are designated by black bearings.

1. Set the unit on a flat surface.

2. Position the unit near the power outlet. Avoid the use of extension cords.

3. Clean the unit thoroughly before use.

4. If the unit fails to operate properly when first installed, contact NEMCO customer service.

1. Turn the on/off switches to the “on” position and make sure the rollers are turning.

2. Turn the temperature controls to the desired temperature:

• Knob setting #2: temperature is at 150°; HOLD

• Knob setting #4: temperature is at 180°; HOLD

• Knob setting #8: temperature is at 220°; COOK

• Knob setting #10: temperature is at 300°; PREHEAT

3. Allow the rollers to heat for 5 to 10 minutes before placing product on them.

4. Plastic tongs are included with units that have Gripsit rollers. Use plastic tongs to prevent serious damage to these rollers. Never use metal utensils or tools on the Gripsit rollers.

Refer to the product tag (serial plate) on the back of the unit for voltage and wattage requirements. Be sure to plug the unit into an outlet with sufficient power.

1. During slow sales periods, turn the rear rollers on low heat and fill rollers with product. Keep the front rollers on medium and serve product from there. Shift product from the rear to the front and reload.

2. During busy periods, set the rear control to medium and the front control to high. Serve from the front rollers first.

3. During very busy periods, set all thermostats on high. Fill all of the rollers with product. At this temperature, product should be sold within 15 minutes.

IMPORTANT: Never serve product from low heat if not approved by the health department. NEVER CHANGE PRODUCT FROM HIGH TO LOW HEAT AS THIS CHANGE IN TEMPERATURE CAUSES THE PRODUCT TO SHRIVEL.

Proper maintenance plays an important part in the life span and functioning of the unit.

1. Turn temperature controls on high and turn rollers on before cleaning.

NOTE: ROLLERS WILL BE HOT DURING THE CLEANING PROCESS. BE CAUTIOUS WHEN CLEANING ROLLERS.

2. ALWAYS START AT THE END OF THE ROLLERS AND WIPE TOWARD THE CENTER. This prevents extra grease from entering the sides of the unit and into the bearings.

• Gripsit rollers: Use a soft cloth to wipe the rollers clean. If the build-up on the rollers cannot be removed by just wiping with a wet cloth, wrap some ice cubes inside a soft towel and rub over the rollers. NOTE: Never use any metal objects on the Gripsit rollers at any time. Metal will cause serious damage to the rollers.

• Chrome rollers: Each unit comes with a two-sided sponge. Use the rough side of the sponge to remove all residue from the rollers. If build-up of residue cannot be removed from the rollers by wiping with a coarse sponge you may use any type of kitchen abrasive to clean the rollers.

3. After cleaning the rollers, remove the drip pan and clean with mild soap and water.

1. Check the power source to be sure the machine is plugged into the proper voltage outlet and that the outlet is in proper working order.

2. IMPORTANT: Disconnect the unit from the power source before disassembly.

3. Remove the end covers.

4. If the drive chain is off the idler sprocket, reinstall it.

5. Remove the drive chain from the sprocket on the motor shaft and if the rollers turn easily, then replace the motor.

6. Remove the chain guard and inspect the sprockets on the end of each roller. If they are loose, worn, or out of alignment, then replace the roller.

7. If the rollers are hard to turn by hand (without the chain attached) remove and clean out any accumulated foreign matter in the bearings and on the rollers.

8. Before reconnecting the chain to the motor, pull the chain by hand. The chain should pull the rollers easily and freely and should not ride up on the sprockets of the rollers and jam against the top of the chain guard. If the chain pulls freely, the motor can be reconnected. Do not reconnect if there is any difficulty with the chain turning since undue strain on the motor will shorten its life.

9. IMPORTANT: Reassemble the machine completely before reconnecting to the power source.

1. Check the capacity of the circuit being used to be sure it isn’t overloaded.

2. Unplug the unit and check its wiring for short circuits.

Check the power source to be sure the machine is plugged into the proper voltage outlet (120 or 220 volt) and the receptacle is working. If properly connected and still no heat, contact NEMCO customer service.

1. Disconnect the unit from the power source, open the control panel by removing both end covers and look for loose connections.

2. If the unit is properly wired, replace the pilot light.

3. Replace end covers and reconnect the machine.

1. Disconnect the unit from the power source.

2. Remove the end cover from the motor side. On single motor units (one on/off switch) the motor is on the left while facing the operator side on the unit. On dual motor machines there is a motor on each side. The motor on the left drives the front rollers and the motor on the right drives the rear rollers.

3. Disconnect the chain from the motor sprocket and then remove the motor sprocket from the motor.

4. Turn the unit over and remove the bottom cover. Disconnect the motor wires and remove the motor screws. Remove the motor and replace with a new motor.

5. To reassemble, reverse the above procedure BEFORE RECONNECTING TO THE POWER SOURCE.

1. Disconnect the unit from the power source.

2. Remove the knobs and the drip pan.

3. Turn the unit over and remove the bottom cover.

4. Loosen nuts or screws that hold the thermostat to the unit. Disconnect wires from the thermostat, replace with a new thermostat and reconnect wires as per the diagram.

5. To reassemble, reverse the above procedure BEFORE RECONNECTING TO THE POWER SOURCE.

1. Disconnect the unit from the power source.

2. Remove the end covers from each side of the unit.

3. Remove the wires and the clips from both ends of the element and remove the element.

4. Remove motor sprocket with 3/32 Allen wrench.

5. Remove the chain guard by removing the two screws.

6. Disconnect the chain from the motor and rollers.

7. Remove rollers and replace with new rollers.

8. To reassemble, reverse the above procedure.
