FAQ’s

The cushion mount if installed correctly will allow your mounting ring to easily drop over it, allowing room for the projections on the disposer to fit into. Looking at the Sink flange you will see a lip below the groove at the very end of the flange.

Note: If the cushion mount is installed correctly the lip at the end of the flange will be fitted into the groove, in the cushion mount.
Examples

Through the use of our Speed Master mounting system, Bio Shield disposers are inexpensive and simple to install. No putty, glues or exotic tools are necessary.

The Bio Shield disposers are designed to fit sinks with a 90mm sink hole. If the sink hole is not this size, it is a simple matter to connect your disposer by use of one of the following methods:
1.   Stainless steel, ceramic or marble sink holes can be enlarged by using either a hole punch tool or a hole saw.

2.   Porcelain sinks can be fitted with a 60mm adapter that is available to replace the current mounting assembly on the Bio Shield disposer.

Improved Health and Sanitary Conditions for their Family
By using a food waste disposer in the home, a homemaker immediately improves the sanitary conditions of the kitchen and waste storage areas. Eliminating food waste through a disposer system effectively removes a major cause of insect and rodent infestation, as well as bad odors.

Convenience and Time Savings
In today’s busy households, using a disposer saves time and provides great convenience in eliminating food waste, especially during meal preparation and cleanup.

  Environmental Concerns
Food waste disposers are the environmentally friendly method of disposing of food waste. They reduce and recycle waste by shredding and pulping the organic food waste material into very small particles that are flushed down the drain.

Our disposers use the latest technology including permanent magnet motors that provide high torque and faster grinding to prevent jams. We also utilize corrosion-proof materials to prevent rust and extend the life of the product.

Bio Shield disposers also provide the following advantages:
Energy Efficiency
Corrosion-Free Materials (Corrosion is the #1 cause of failure in the competitor’s units.)
Competitive Pricing
Exceptional Quality Standards
Compactness

All models work by simply and safely grinding food waste material into very fine particles, which are then flushed through the waste pipes without harm. Since Bio Shield disposers use no blades or knives, they are very safe to operate.

No, waste disposal with the Bio Shield disposer is quite simple. Four easy steps are all that is needed:
1. Turn on the Water.
2. Switch on the Bio Shield disposer.
3. Scrape the food waste into the disposer.
4. Let the water and the disposer run for 25 seconds after the waste is gone and then turn off the water and the disposer.

None of the models are noisy, but the degree of sound insulation improves with the model range. The Heavy Duty and Deluxe models are exceptionally quiet due to their full sound shell insulation. All of our disposers feature the exclusive Torque Master Grinding System with its balanced turntable and armature help keep noise and vibration to a minimum.

This is a problem mostly experienced with our competitor’s products. They use induction motors which are slow starting and could jam if food is placed in the disposer before it is switched ON. Bio Shield disposers are designed not to jam by using permanent magnet motors. This motor produces high torque (twisting power) immediately when switched on. This feature prevents jams. In the unlikely event that a Bio Shield disposer jams, dejamming is very simple. Turn off the switch to the disposer, check for foreign objects, dislodge the object by rotating the turntable with a long screwdriver or broom handle and remove the object.
DEJAMMING

No, because Bio Shield disposers are constructed from stainless steel (grinding components) and thermoplastic materials (grinding chamber). With the exception of the Economy unit, all models are covered by a lifetime corrosion warranty. The grinding components on the Economy model have the capacity to corrode eventually; this does not impede the operation of the unit.

Some waste disposers smell because food accumulates under the Splashguard, allowing bacteria from food particles to grow and generate odors. This cannot be cleaned with our competitor’s units without removing and dismantling their disposer from the sink. All Bio Shield disposer models have a Splashguard that is easily removed from the top of the sink for cleaning or replacing. Food odors are eliminated if this is done regularly. We also are the only disposer with Bio-Shield antimicrobial for odor protection. Our other products, including Mr. Scrappy Disposa Clean and Disposer Brush can be used for effective odor prevention (Mr. Scrappy Disposer Accessories).

SPLASHGUARD

All motors have the capacity to wear out eventually. How quickly depends on the stress or the load placed on the motor. The Bio Shield disposer models are designed to be long lasting. The durability and performance increases through the model range. The Heavy Duty and Deluxe models have slightly bigger motors which generate more torque and cutting power. This puts less stress on the motor, giving the Bio Shield disposer longer life.

The use of permanent magnet motors in Bio Shield disposers is vital. The nature of the motor is that it increases torque as the load increases. This not only means top performance when a full load of food waste is being ground, but also prevents jams from occurring frequently.

NO.  They contain no knives or blades… they use centrifugal force generated by the turntable to hurl the food waste against the grinding ring, shredding it into fine pieces.

The Bio Shield food waste disposer will take most types of food waste, including:

DO:

• Use a medium flow of COLD water. If hot water is used, grease tends to coat the pipes instead of being flushed away.
• Grind hard materials (cooked bones, pits of fruit). This is necessary every so often to keep the lugs moving freely and to keep the grind chamber clean.
• Do continue running cold water for 25 seconds after grinding is completed to flush the drain line. Remember the drain line from your sink may run for 30 feet or more before it exits your home.
• Flush for cleaning with cold water. An occasional lemon or lime slice will help to deodorize the grind chamber and elements.

DON’T:

• Don’t use HOT water when grinding. It is acceptable to drain hot water into the disposer between grinding periods.
• Don’t turn off disposer until grinding is complete. Wait until ALL food is ground before turning the disposer off.
• Don’t grind extremely fibrous materials (corn husks). These materials tend to form hard clusters of fiber which do not drain properly and interfere with the grinding elements.
• Don’t fill disposer with a lot of vegetable peels all at once. Instead, turn the water and disposer on first, and then feed the peels in gradually.
• Don’t grind clam or oyster shells, glass, metal, cloth, or harsh chemicals. These materials are too abrasive and will eventually wear down the grind chamber.
• Don’t dispose large amounts of fat or hot grease in food waste disposers.

B.  CONVERT TO PERMANENT WIRE INSTALLATION  1. Remove Cord and Plug from the disposer – Simply cutting the plug off the existing cord is not allowed and voids the warranty.  2. Follow instructions below for Permanent Wire Installation instructions.  PERMANENT WIRE

INSTALLATION INSTRUCTIONS
Grounding Instructions
This disposer must be connected to a grounded, metal, permanent wiring system; or an equipment-grounding conductor must be run with the circuit conductors and connected to the equipment-grounding  terminal or lead on the disposer.     An acceptable motor control switch with a marked off position shall be provided at the time of installation  to disconnect the disposer from all ungrounded supply conductors. The switch shall be mounted in sight  of the disposer or in sight of the sink opening for the disposer.

WARNING: Electric Shock    Turn off power before installing or servicing disposer.  All wiring must comply with local  electrical codes. Do not connect electrical current at main breaker panel until adequate  ground is established. Inadequate connection of the ground wire can result in a risk of electric  shock. Consult with a certified electrician or tradesman if there is any doubt whether the  disposer in inadequately grounded. Your disposer must be adequately grounded.

1. Turn off or disconnect all power to the wall junction box serving the disposer.

2.  Open the junction box in the wall and remove the wire nuts or electrical tape or  whatever is tying the old disposer wire to the electrical wire inside of the junction  box.

3.  Open the end bell plate at the bottom or the disposer.  If you are using flexible armored (BX) cable:  1.  Install cable fitting in the disposer end bell hole.

If you are using flexible armored (BX) cable:
1. Install cable fitting in the disposer end bell hole.
2. Secure the cable to the fitting and install an insulating bushing or equivalent.
3. Connect white wire from the junction box to the white (or blue) wire of the disposer.
4. Connect black wire from the junction box to the black (or brown) wire of the
disposer.
5. Connect bare ground wire from the junction box to green ground screw within the
disposer end bell.

If you are using nonmetallic-sheathed (ROMEX) cable:
1. Install cable fitting in the end bell hole and secure the cable to the fitting.
2. Connect white wire from the junction box to the white (or blue) wire of the disposer.
3. Connect black wire from the junction box to the black (or brown) wire of the
disposer.
4. Connect bare ground wire from the junction box to green ground screw within the
disposer end bell.

If your power supply cable does not include a grounding wire, one must be provided. Attach a copper wire securely to the disposer ground screw and attach other end of ground wire to a metal cold water pipe. Do not attach ground wire to a gas supply pipe. Use only UL Listed grounding clamp. If plastic pipe is used in your home, a qualified electrician should install a proper ground.

Too much hot water directly on the splashguard will cause it to deform. Replacements available through our Mr. Scrappy Store.

Unless your model specifies that it is Batch Feed or BF, it is a continuous feed disposer.

Note: Both Continuous Feed and Batch Feed versions have the same grind process but different on/off switch mechanisms and modes of loading the food waste.

Continuous Feed models require a wall switch (or Air Switch option). Food waste is fed through the splash guard and can be added to the grind chamber all the time the unit is running.

Batch Feed Disposers include the On/Off switch in the throat of the Disposer and after food is placed in the grind chamber the switch is activated by the sink stopper. Only water is allowed to enter the Batch Feed unit whilst in operation. As soon as the sink stopper is removed the disposer automatically turns off.

Yes.  When  Stainless Steel Impellers swing into position a brief noise may occur from contact with a protrusion on the turntable. The noise should be brief not continuous.

It could be a power problem. Check the power to the circuit that feeds the disposer. If the breaker is OK, then check the power at the switch. If you have power coming to, but not leaving the switch, then the switch is bad. Turn the circuit off and replace the switch.

All of our disposers feature the exclusive  Torque Master Grinding System with its balanced turntable and armature that help keep noise and vibration to a minimum, however, it can become really noisy if something gets in there to cause a ruckus. With the disposer unplugged, grab a flashlight and take a look down the drain and see if you notice anything that can be causing the noise. Plastic or metal items are usually the culprits.
