Thorough cleaning of the oven is a weekly task. Weekly cleaning includes the fingers, conveyor, end baffles, door, 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 a non-caustic degreaser, a mild solution of 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 end baffles. Remove the end baffles by turning the thumb screws counter-clockwise. Spray them with non-caustic degreaser, and allow them to sit while cleaning the conveyor. To remove the conveyor on a 1400 series impinger oven, remove the external crumb trays, then release the four conveyor hold-down brackets by sliding each in the opposite direction of the notch and rotating upward. Remove the conveyor drive sprocket shield, lift the conveyor, and slide it two to three inches into the oven cavity. This will put slack on the drive chain and allow for its removal. Lift and slide the entire conveyor out towards you. Removing the conveyor will require two people. We'll clean the conveyor over a three-compartment sink. We're going to start by using our non-caustic degreaser. Spray the entire conveyor assembly with non-caustic degreaser. It will take about twenty minutes for the grease to dissolve. Then, rinse and allow to dry. Now it's time to remove and clean the fingers. One word of caution: If the fingers get mis-adjusted during cleaning or get re-installed in the wrong spots, you'll experience baking problems. Pay attention to how each finger is adjusted and replace each in the same position in the oven. Remove the top center fingers first. Then, lift up and remove the other top fingers. Remove the top finger support bracket. Remove the bottom center fingers next, then the remaining bottom fingers. Remove the bottom finger support bracket. Okay, the fingers are out, so let's start cleaning. First, slide the cover off the small end of the finger. Lift out the inner finger panel, also called the calumniating panel. Spray the finger covers with non-caustic degreaser. Remember, it will take about twenty minutes for the grease to dissolve. Wash the finger housings and calumniating panels in warm soapy water in the three-compartment sink. Rinse off all parts with clear water, then stand all the parts up to 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. Do not use a caustic oven cleaner or degreaser on the interior of the oven. Don't forget to clean the outside, too. Non-caustic degreaser can be used for spot application on the outside of the oven, if needed. Rinse with clean water inside and outside when finished. The parts you washed should be dry by now, so let's put the fingers back together. With the panel number facing up, insert the calumniating panel so it fits under the lip of the finger housing. Slide the cover over the finger. Now, we can re-install the fingers. Install the bottom finger support bracket. Install the bottom fingers. Next, install the top finger support bracket and install the top fingers. Remember that you laid them out in order so that you'd remember how they go back in. Make sure all the finger housings are fully seated around the plenum flanges. The holes must point toward the conveyor. Clean all the vents and louvers that are on the right-hand side and the rear of the oven. Cooling fan covers need special attention. Keeping these clean allows cool air to circulate into the control box and around the main fan motor, prolonging oven component life. When the conveyor is dry, hold the right hand up slightly and reinsert the conveyor in the oven. To hook up the drive chain, lift the conveyor slightly and push it into the oven. Then attach the chain to the drive chain shaft. Pull the conveyor toward you so the bar locks on the outside of the oven wall. Then rotate the four conveyor hold-down brackets by sliding each in the opposite direction of the notch and rotating downward. Re-install the drive sprocket shield. Never operate the oven without the guard. The impinger 1400 series advantage oven conveyor should not, in most cases, need any adjustment. But, if the belt becomes too loose, consult the installation operating instructions manual or call your service agency to adjust it. Rinse the end baffles. Dry thoroughly and re-position each over the oven cavity opening. Next, slide the crumb pans into the rails under the conveyor. Spray the stand frame and casters with non-caustic degreaser and allow to sit. Rinse with clear water and wipe dry. Be sure to clean up any overspray on the floor. Let's review our weekly cleaning jobs: We disassembled and cleaned the conveyor belt, and baffles, and the fingers. Then, we cleaned the inside and outside of the oven, including the air intake vents and louvers, and the stand, and then re-installed the fingers, baffles, and the conveyor belt.
The weekly cleaning procedure for 1400 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 1. probe fail. This occurs when there is no temperature being sent to the controller from the baking chamber. This generally means a malfunctioning or failed thermoprobe. 2. shorted probe. This occurs when a constant temperature signal is being sent to the controller from the baking chamber. This will happen if there's no heat being supplied to the oven for some reason. This can occur if the gas valve is shut off or disconnected. 3. belt jam. This will occur when there is 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 therms of the symptom you observe and what might be causing it. You go to 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 indicator light. Does it show that the oven is heating? If not, see if the temperature is set to the right temperature. If the thermostat is set right, see if the main fan is working by checking for air movement. If there is no air movement, the fan isn't 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 is nothing more 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 shutoff valve is open. Check for kinks in the gas hose and make sure the gas connector is firmly locked into its receptacle. Beyond this, there is nothing more you can do. Your authorized Lincoln service agency must be contacted. Burnt products result from too high a temperature, too long a cooking time, or improperly installed calumniating 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 show's it's set properly, time it against a stopwatch. Start the stopwatch when the leading edge of the pan enters the oven. Stop the watch when the leading edge exits the oven. If the conveyor speed mechanism needs re-calibration, your authorized Lincoln service agency must be contacted. In the meantime, you can try to compensate by adjusting the conveyor speed 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 temperature is set properly, but the products are undercooked, the oven could be out of calibration. If the conveyor speed shows it's set properly, time it against the stopwatch 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 adjusting the belt speed up or down until help arrives. If time and temperature aren't your problem, it could be the calumniating 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 fan fuses. If you have a gas-fired oven, check to be sure the main shutoff valve is open. Check for kinks in the gas hose and be sure that 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 sprocket chain to ensure it's connected properly. Take corrective 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 cannot start accidentally, disconnect the drive sprocket chain. 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 that the motor shaft is rotating. If the motor drive shaft won't turn, you'll 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 cavity. 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 clean, 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 - Lincoln part #369217. Next remove the conveyor crumb pans and the take-off shelves, if purchased with the oven. Wash with oven 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 six 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 conveyor crumb pans and take-off shelves. We cleaned up loose particles inside the oven and checked the area for combustible materials.
