InSinkerator Disposer Installation

About Transcript Embed
The following procedures will help you install an InSinkerator food service disposer properly. First, if this is not a new installation clear the drain line of any waste. Auger the drain line from the drain trap to the main waste line to ensure that it is clear. A typical installation incorporates the following items: Disposer, disposer mounting, control center, solenoid valve, flow control valve, syphon breaker, electrical supply, drain line, water shut off valve, and the cold water supply. Prior to unpacking, verify the carton labels match each other and the power supply. After unpacking check to ensure that the spec plate on both the disposer and the control panel match the power supply. If required, install the disposer leg assembly on the SS-50 to SS-200 disposer. Note that the SS-300 and the larger disposers come with factor install legs. If your disposer is using a competitive mounting adapter it is recommender to install it with legs. Also use legs if the SS-120 and SS-200 is using the # 5 flange. To install the legs, first turn the unit upside down. Pry two guide hole plugs from the bottom cover. Make sure that the threaded stud is extended a minimum of 1-1/8” from the outer tube assembly. Insert the leg assemblies through the lower frame guide holes. Insert the screwdriver into the tube assembly and position in the slotted end of the threaded stud. Tighten the threaded stud into the threaded holes located in the upper end bell, and tighten both studs. Place the O ring on the tuber assembly and push up flush against the bottom cover. Place the washer inside of the guide hole plugs, and place on the bottom of the outer tube assembly. Now, you’re ready to install the disposer. The legs can be adjusted by turning the outer tube assembly until the assembly legs stand on the floor. To mount a disposer to an InSinkerator sink bowl or #6 or #7 mounting adaptor follow these instructions. Place the mounting flange up over the existing color adapt connect lip. It may require a slit force fit. Force the mounting flange up out of the way and fit the mounting gasket onto the sink bowl connect lip. Move the mounting flange down over the mounting gasket. Be certain that the threaded fasteners in the mounting flange fit into recesses into the top of the mounting gasket. Attach two screws through opposite holes in the mounting gasket and into the threaded fasteners in the mounting flange. The screws should be protruding approximately 1/4” below the mounting gasket. Position the disposer beneath the mounting gasket and engage the two protruding screws into key hole slots in the disposer body flange. This may require the use of an assistant or a block of wood to ease installation. Assembly the remaining 4 screws and turn the disposer into place for plumbing connections. Tighten all screws evenly to secure the unit. To install a #5 sink flange follow the instructions supplied with the kit. The #5 sink flange mounts to a standard 3-1/2 to 4” opening. When installing an InSinkerator disposer to another type of sink bowl, a special mounting adaptor is required. WE have a adaptors to fit most sink designs. Control the adapter guide for more information. When connecting the disposer to the incoming water supply, use as few elbows and tees as possible. Connect to the cold water line only. Install the flow control valve, water solenoid valve and the syphon breaker according the direction of the flow arrows marked on each valve body. It is recommended to use as shut off valve. Use the supplied water flow restrictor to ensure you have the proper flow. If there is too much water in the disposer the food will not grind completely. If there is too little water in the disposer, the food waste may not flow to the main sewer line. When connecting the drain line place the p-trap or floor drain as close to the disposer outlet flange as possible. Do not use plumbers putty on the threaded connection, instead use tape. Do not flex the connection. Consult the installation guide to find the recommended drain line diameter for your disposer’s model. Check to make sure that the proper slope is use with the connection going from the disposer to the floor drain or sewer connection. With this installation, we’re showing you the aquasaver disposer control center, which operates the disposer and control center operations. Each control has its own installation manual detailing how to connect the disposer, control, solenoid valve and power supply. Make sure the control center is properly grounded. If this is a new installation make sure that there is no construction debris in the disposer grind chamber. Verify the disposer is function properly by checking for leakers and the fresh water connections, mounting color and the waste outlet. Checking for excessive vibration and if the control center has reversing capabilities, confirm that it will reverse. If the control center is equipped with a post flush, ensure that the water runs after the disposer is turned off per the post flush setting: one – ten minutes. For more details on troubleshooting and operation, reference the installation manual included with your disposer. All disposers are backed by a one year one-site warranty on parts and labor.

InSinkerator Disposer Operation

About Transcript Embed
The following procedures will help you operate and InSinkerator food service disposer properly. First, let’s discuss what should and shouldn’t be placed into the disposer. Items that can be placed into the disposer consist of fruits, vegetables, meat, poultry dairy products, breads and grain products, bones and seafood. Items that should not be placed into the InSinkerator disposer consist of large amounts of string and fibrous materials such as artichokes, pineapple tops, corn husks as well as oyster shells as these items may cause drain line clogs. It is also recommended to avoid silverware, soda cans, glass, lids, plastic wrap, latex gloves and corrosive chemicals. Now we’re ready to operate the disposer. If this is a new installation make sure there is no construction debris in the disposer grind chamber. Do not preload the disposer with food waste prior to starting. Push the start button on the control panel to turn on the disposer and start water flowing into the disposer. Feed food waste into the disposer in a steady continuous flow. This food waste is ground into small particles in the disposer grind chamber. The ground food waste is then transferred through the plumbing into the main sewer line and ends up at the waste water treatment plant for processing. After all food waste is flushes away, allow the disposer to run for 30-60 seconds to clear itself before pushing the stop button on the control center to stop the unit. If a disposer should experience a jam, the disposer overload will trip. To free a jam follow these steps: Turn the control off and if equipped turn on the disconnect switch. Reach into the disposer and remove the excess material. Does the rotating shredder spin freely? If not, place the de-jamming wrench down onto the rotating shredder bars and rotate back and forth until the jam is free. Then remove the jammed item. Press the disposer overload reset button. If equipped, turn on the disconnect switch and wait 30 seconds. Turn the disposer on and begin feeding food waste into the disposer. To not use a hammer and pry bar as this may damage the rotating shredder. In review, to ensure optimal operation of your InSinkerator food waste disposer, we recommend that you start the unit prior to loading it, avoid batch feeding, gradually feed food waste and allow the unit to run 30-60 seconds after the last load of food waste has been processed. Using an InSinkerator food service disposer will help you reduce labor cost. Reduce waste hauling charges, increase efficiency and improve sanitation in your kitchen. And its good for the environment by keeping food waste out of landfills while using minimal water and electricity. Also, food waste put down the disposer can be captured as bio solids and used a fertilizer. Methane gas produced during treatment can be captured and recycled as energy. For more details on troubleshooting and operation reference the installation manual included with your disposer. All disposer are all backed by a 1 year one site warranty on parts and labor.

HI, I'm Don from InSinkErator. Today I'm going to show you a couple ways to clean the inside of your garbage disposer. Disposers don't require any maintenance, but occasionally, you can do some cleaning on it if you want, just to minimize any odors that might be happening. Sometimes a little build up of food can be up there and also in the throat of the disposer. I would just rinse this baffle off. What I also like to do is take some paper towel and just get inside right underneath the lip and just wipe off the other side. The removable baffles are also dishwasher safe. If you notice any odors coming from your disposer, you can grind a citrus fruit like lemons or oranges, it'll help to neutralize the odors, and also keep it smelling fresh. Or you can use something more solid like a fruit pit or some bones that will help bounce around and clean things even further. Some people think that grinding ice helps clean the disposer and sharpen blades. But in reality, there are no blades in a disposer, and the ice just basically melts very fast and goes right through. But by all means, you can grind ice.

There are a variety of ways to clean your disposer, and this video shows you how! You can grind citrus fruit, chicken bones, or wash the baffles.

Hi, I'm Don from InSinkErator. I'm going to help you with the new disposer installation. These are the essential tools you will need for this project. Before working on your garbage disposer, always be sure to turn the circuit for the electric off. I'm going to start by loosening up the existing plumbing and removing it. I'll use a bucket underneath to catch any water, just like that. Next I will remove the strainer flange which has a nut on the bottom, and the top just gets pulled out. Make sure you clean up any old plumber's putty or debris off the sink opening before you install the new mounting flange. The mounting assembly comes put together right on the box, so to disassemble it, loosen these 3 screws and then remove the snap ring and it all comes right apart. Some InSinkErator disposers come with a rubber gasket, but in most cases, you'll need to use plumber's putty, so make a rope, put it around the sink opening, and then push your flange in. When installing the bottom side of the mounting assembly, make sure that the screws are backed all the way out, leaving some room for when you put in the snap ring. And make sure that the fiber gasket is on the top side of the bottom of the sink, just like that. Push this up on the flange and then put the snap ring back in place. And then tighten the three screws nice and snug so nothing rotates. Remove excess plumber's putty. I'm installing an InSinkErator Evolution Compact model and we have a dishwasher that needs to be hooked up, so I have to knock out the dishwasher plug that's in here and I take just the flat screw driver with a hammer and I kind of work my way around it and a little flat plug will fall inside the compact disposer. When installing an InSinkErator disposer, there's 3 ramps on this mounting assembly, this sits on the underside of your sink and you want to make sure that the 3 tabs on this lacking ring line up and match on this ramp. You'll finally clamp it over all the way and that'll lock it down tight against the gasket. Now I'm going to install this in the sink against the mounting assembly. If you start those 3 tabs on the ramps it'll hang by itself, and what I like to do is use the supplied wrench along with a screw driver and put them in the little loops that are on the mounting ring, and then I can get better leverage for clamping it over. Next you can put the tailpipe in and on the Evolution model it's a rubber coupler, and make sure the tail pipe is fully seated in there and make sure to use the supplied clamp ring that goes with it, put that in place. It's easier to take the gasket and push it up onto the tail pipe first and you can move it into place. Finish tightening everything down by hand, the dishwasher tube can be put on the disposer, and then tighten the clamp back up. Plug the disposer in. After you install the disposer, turn the water on in the sink and check for any leaks. Re-tighten any fittings if necessary.

How to replace your InSinkErator disposer. Hi, I'm Don from InSinkErator. Today I will be replacing a standard InSinkErator disposer with this Evolution Series model. These are the essential tools which you will need to replace an InSinkErator disposer with another InSinkErator disposer. Before working on your garbage disposer, always make sure to turn the circuit to the electric off. You want to make sure the power is off, this unit has a cord, so make sure it's unplugged. We'll start by taking off some of the plumbing, take the dishwasher discharge hose off. Loosen this clamp. Use a slip wrench to loosen up some of the fittings back here. If you need to, you can turn the disposer. On it's mounting assembly, there are two parts that meet together. The way to disassemble that is to use the wrench that's provided and also use a screw driver just to get better leverage. Rotate it counter clock wise and pop it loose. What that does is disconnect the pressure off the gasket, and then support it on the bottom, and then by hand, you can rotate it the rest of the way. So I removed the other disposer and i'm installing an Evolution Excel. Since we have a dishwasher on this and we have a dishwasher discharge line, we need to take this knock out which is a little plug and open that up. I take a screw driver, pound around the perimeter of the plug until it comes out, and here it just popped out. Now that will allow the dishwasher water to go in here and properly drain out. With this model, it has a different type of tail pipe than the standard model which goes inside this rubber cup hole. And it also comes with its own supplied spring clamp. You want to make sure it's kind of centered in the groove there and everything looks snug. With that being on, I think we're ready to put this in the sink. In the bottom of the sink you have a mounting assembly. On this mounting ring there are three tabs. These 3 tabs have to match up with these 3 ramps. Eventually these tabs will end up way over here, and they'll lock and hold the disposer up in place to seal it up against the rubber gasket. So we're going to bring the new disposer in. You need to lift this up against the mounting assembly, and you can see that the mounting tab here is above and i'm just going with my fingers to make sure all 3 are above. Once all 3 tabs are partly engaged it should hang by itself. For locking this mounting ring use the supplied wrench head and I assist it with the screw driver, go as far as you can. In the end I like to use the slip-joint pliers and just lock it in place. So then it's just a reversal of what we did to take this out. Start by putting the nut and washer on the discharge pipe, and we can rotate the disposer around so everything lines up. Put the dishwasher discharge pipe on, put the clamp in place, just snug everything up. One of the last steps is to plug the disposer back in, after tightening up the plumbing down below just turn the water on and then go down to check for leaks. I like to use the mirror, just look for any drips that might happen. Everything looks good on this one.
