Thorough cleaning of the oven is a weekly task. Weekly cleaning includes the fingers, conveyor, end baffles, door, air intake vents, and stand. This process should take about an hour per oven. Be sure to leave the ventilation systems operating while cleaning the oven and be sure your work area is well ventilated.
You'll need an oven non-caustic degreaser, a mild solution soapy water, a three to five gallon bucket of warm rinse water, an oven brush, four or five dry towels, and a three-compartment sink with faucet and sprayer. You'll need a long sleeve cotton shirt, a pair of goggles, and rubber gloves.
The first weekly cleaning task is removing and cleaning the conveyor and end baffles. Remove the end baffles by turning the thumb screws counterclockwise. Spray them with the oven non-caustic degreaser and allow them to sit while cleaning the conveyor. To remove the conveyor on an Impinger II Advantage oven, remove the external crumb trays, remove the drive sprocket shield, hold the rubber coupling, and pull it towards the conveyor. Then lift the conveyor so the locking tab is clear. If the conveyor will not release easily, lift the opposite end and push.
We'll clean the conveyor over a three-compartment sink. We're going to start by using our oven non-caustic degreaser. Spray the entire conveyor assembly with oven non-caustic degreaser; it'll take about 20 minutes for the grease to dissolve. Then rinse and air dry. The door of the Impinger II Advantage oven can be removed by lifting from the hinges. Do not submerge the door or get it unnecessarily wet, this will damage the installation. Wipe the door with warm soapy water, then rinse and dry.
Now it's time to remove and clean the fingers. Remove the top finger first by lifting up and pulling towards you. Move the bottom finger next by pulling towards you. Now disassemble the finger housing for cleaning. Slide the finger covering from the housing, lift out the inner columnating panel, spray the finger covers with oven non-caustic oven degreaser and allow to sit for 20 minutes. Wash the finger housings and columnating panels in warm soap water in the three-compartment sink. Leave the close-off plates, if being used, securely locked to the columnating panel. Rinse off all parts with clean water when they are thoroughly cleaned. Then stand all the parts up to air dry.
While you're waiting for the fingers and conveyor to dry, you can clean the inside of the Impinger oven. Remember that this is a daily task, but now that the fingers are out, you'll be able to clean more thoroughly. Use a non-caustic degreaser. Don't forget to use the outside too. Non-caustic degreaser can be used for spot applications on the outside of the oven, if needed. Do not use a caustic oven cleaner or degreaser on the interior of the oven. Clean all the vents and louvers that are on the right hand and rear of the oven. Cooling fan covers need special attention, keeping these clean allows cool air to circuit into the control box and around the main fan motor, prolonging oven component life.
The parts you washed should be dry, so let's put the fingers back together. With the panel number facing up, insert the columnating panel so it fits securely inside the finger housing. Any close-offs used for oven zoning should be secure but check to make be sure locknuts are tight. Slide the cover over the finger. Now we can reinstall the fingers. Make sure the finger housings are fully seated around the plenum flanges. Air jet holes must point towards the conveyor. When the conveyor is dry, hold the right hand and reinsert the conveyor into the oven. Now connect the drive sprocket and tighten the set screw. Rinse the end baffles, dry thoroughly, and reposition over each oven cavity opening.
The Impinger II Advantage oven conveyor should not need any adjustment, but if the belt becomes too loose call your service agency to adjust it. Next slide the crumb pans into the rails under the conveyor, and install the optional conveyor take-off shelf. Replace the door by setting it back into the hinges. Spray the stand frame and casters with oven non-caustic degreaser and allow them to sit. Rinse with clear water and wipe dry. Be sure to clean up any over spray on the floor.
Let's review our weekly cleaning jobs. We disassembled and cleaned the conveyor belt, crumb pans, baffles, and the fingers. Then we cleaned the inside and outside of the oven, including the air intake vents and louvers and the stand. Then we reinstalled the fingers, conveyor belt, crumb pans, and end baffles.
The weekly cleaning procedure for 1100 series Impinger ovens from Lincoln is reviewed. Follow these guidelines to keep the exterior and interior clean.
Your new Impinger is equipped with three diagnostic messages to help you troubleshoot a specific problem yourself or at least help you narrow it down. The messages you might encounter on the digital display are one, probe fail. This occurs when there's no temperature being sent to the controller from the baking chamber. This generally means a malfunctioning or failed thermoprobe. Two, shorted probe, this occurs when a constant temperature signal is being sent to the controller from the baking chamber. This will happen if there is no heat being supplied to the oven for some reason. This can occur if the gas valve is shut off or disconnected. Three, belt jam, this will occur when there's a conveyor motor failure. These messages should be noted and communicated when calling your Lincoln authorized service agent.
Now let's talk about what to do if your Impinger oven seems to be malfunctioning, but there are no diagnostic messages displayed. Before you make a service call, there are a few things you should check out.
We'll look at troubleshooting in terms of the symptom you've observed and what might be causing it.
You turn on the oven at the beginning of the work day and it did not respond by heating up. Always suspect the easy stuff first. Is the oven plugged in tightly? Check the temperature display, does it show that the oven is heating? If not, see that the temperature is set to the right temperature. You may then need to hit the red thermostat reset button. If the thermostat is set right, see if the main fan is working by checking for air movement. If there's no air movement, the fan is not working, so check the main circuit breaker and the main fan fuses on the oven. If you find a bad fuse, replace it. If the fuses are okay and you have an electric oven, there's nothing more that you can do, your authorized Lincoln service agent must be contacted. If the fuses are okay and your oven is gas fired, be sure the main shut-off valve is open. Check for kinks in the gas hose and make sure the gas connector is firmly looked into its receptacle. Beyond this, there's nothing more you can do, your authorized Lincoln service agent must be contacted.
Burnt products result from too high of a temperature, too long of cooking time, or improperly installed columnating panels. First see if all the fingers are installed properly. Then check the temperature set point. If the temperature is set properly, but the products are overcooked the oven could be out of calibration. If the timer shows it's set properly, time it against a stop watch. Start the stop watch when the leading edge of the pan enters the oven. Stop the watch when the leading edge exits the oven. If the time/temperature mechanism needs recalibration your authorized Lincoln service agency must be contacted. In the meantime, you can try to compensate by adjusting the times up or down until help arrives.
Undercooked products can result from several things. First be sure you're not placing the food product too far into the oven cavity. The leading edge should be just at the conveyor opening and don't pull the product out of the oven too soon. Next if the display shows the temperature is set properly, but the products are undercooked, the oven could be out of calibration. If the timer shows it's set properly, time it against the stop watch, using the leading edge in to leading edge out method we used earlier. Again if the time/temperature mechanism needs calibration, your authorized Lincoln service representative should be contacted. And of course you can compensate by decreasing the belt speed up or down until help arrives. If time and temperature are not your problem, it could be the columnating panels were not installed properly. If you're still having a problem, see if the main fan is working by checking for air movement. If the fan isn't running, check the main circuit breaker and the main fuses. If you have a gas fired oven, check to make sure the main shut-off valve is open. Check for kinks in the gas hose and be sure the gas connector is firmly locked to its receptacle. If you do all this and the oven is still not performing properly, it's time to call your authorized service agency.
Another situation you might run into is a conveyor belt that won't move. If this happens, your display might show the diagnostic message: belt jam. This occurs when the conveyor motor fails, so you'll need to call your Lincoln authorized service agency. If this does not happen, check to see that the belt speed control was not accidentally turned all the way down. Check the drive coupling to ensure they are connected properly. Take corrected action as needed. Next check your main circuit breakers and fuses. If the conveyor stopped when the oven was hot, it could be overheating. Check and clean the ventilation louvers and cooling fan covers if needed. It could also be a mechanical malfunction. With the circuit breaker off, so the conveyor can't start accidentally, disconnect the coupling. Then gently push and pull the conveyor to see that it moves freely. If it doesn't, look for some obstruction or binding. If the conveyor moves freely, then turn the circuit breaker back on, turn the oven on, and check to see if the motor shaft is rotating. If the motor drive shaft won't turn, you will have to call your authorized Lincoln service agency.

To make the impinger weekly cleaning tasks easier, there are spray on soil shields available. These soil shield products are applied on clean oven parts, finger covers, the backside of the oven door, and the inside oven cabinet. After application, the soil shield product should be dry to the touch before baking food in the impinger oven. Then, when you perform your next weekly cleaning tasks, the accumulated grease and debris rinse off with warm water. A new application is then applied, and the cleaning cycle is continued. Consult your chemical or janitorial distributor for the names and availability of these products.

Daily cleaning is a simple process. First, using clean water and a non-caustic degreaser, wipe the outside surfaces with the grain using a soft cloth. Then, rinse with clean, warm water. Polish with a stainless steel cleaner. Always wipe with the grain using a soft cloth. The next daily job is to clean the conveyor belt. Brush it with a special wire brush, like the Wear-Ever 369217. Next, remove the crumb pans and the optional take-off shelves. Wash with non-caustic degreaser and rinse with clean water. Then clean loose particles from the bottom of the oven, and wash the inside with a mild solution of soapy water. Rinse the inside with clean water also. Make sure the oven is at least 6 inches away from walls and combustible materials. Let's review the daily cleaning list. We cleaned and rinsed the exterior. Then we cleaned the conveyor belt with a wire brush. Then the crumb pans and take-off shelves. We cleaned up loose particles inside the oven and checked the area for combustible materials.

Your impinger oven is equipped with a state-of-the-art digital controller. The panel has a single on/off power switch, which operates the fan, conveyor motor, and heat. The easy-to-use four push-button panel controls time, temperature, up, and down. The BFD display indicates the actual cavity temperature, conveyor speed, and heating indicator.
Follow this procedure for operating your Lincoln impinger ovens. First, make sure your ventilation, if you have it, is on and running properly. Then, to start the oven push the on switch to on. Next, check to ensure that the oven is set for the correct bake time temperature. You do this by pushing the time and temperature buttons at the same time for five seconds. This enters the set point mode. Once in set point, push the time button to see the set time. If set incorrectly, adjust to the proper time by scrolling up or down with the arrow keys. Once the time is set push the temperature button to enter the temperature set point. The preset time will automatically be saved in the memory. If the temperature is set incorrectly, adjust to the proper temperature by scrolling up or down with the arrow keys.
When in Fahrenheit, or "F" mode, the temperature is adjusted in five degree increments. When in Centigrade, or "C" mode, the temperature adjustment will be in one degree increments. Once the time and temperature are set correctly, release all buttons. After five seconds the selected set points will be stored in the memory. In a few seconds the heating indicator should come on. If the indicator does not light, turn the on switch off, wait five minutes, and turn the switch on again for gas ovens only. Allow thirty minutes for the oven to preheat.
To shut down the impinger, push the on switch to the off position. Caution: oven walls and parts will remain very warm after shut down. You may also choose the direction of the conveyor belt. Use the conveyor toggle switch on the back of the oven.
