Important Safety Information
WARNING: Risk of electrical shock. Always disconnect power before installing or servicing the disposal.
WARNING: Risk of injury. Do not put hands or fingers into the disposal opening. Use a long-handled utensil to remove objects.
- Ensure all local electrical and plumbing codes are followed.
- This appliance must be properly grounded.
- Do not dispose of glass, metal, plastic, large bones, or fibrous materials like corn husks or artichokes.
- Never pour caustic drain cleaners into the disposal as they can cause serious damage.
Setup and Installation
The US-MW5-50-NC garbage disposal is designed for 3-bolt mounting systems and can attach easily to existing 3-bolt installations, often without requiring re-plumbing when replacing prior Maintenance Warehouse or Premier disposers.
1. Prepare Mounting System
If replacing an old disposal, remove it. Ensure the sink flange and mounting ring are clean and properly sealed to the sink opening. This model is compatible with standard 3-bolt mounting assemblies.

2. Electrical Connection
This unit requires a 120V, 60Hz, 4.5A direct wire electrical connection. Ensure the power supply is turned OFF at the circuit breaker before making any electrical connections. Connect the disposal's wires to the household wiring according to local electrical codes. The disposal must be properly grounded.

3. Plumbing Connection
Connect the disposal's drain elbow to the household drain pipe. Ensure all connections are tight and leak-free. If connecting to a dishwasher, remove the knockout plug from the disposal's dishwasher inlet.

Operating Instructions
To operate your garbage disposal:
- Turn on the cold water faucet to a moderate flow.
- Turn on the disposal switch.
- Slowly feed food waste into the disposal opening. Do not overload the unit.
- Allow the disposal to run until all waste is cleared and only the sound of the motor and running water is heard.
- Turn off the disposal switch, then turn off the cold water after a few seconds to flush the drain.
The included stopper can be used to plug the sink opening when not using the disposal or to fill the sink with water.

Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your disposal.
Cleaning the Disposal
- Removable Splash Guard: The splash guard is removable for easy cleaning and replacement. Periodically remove the splash guard and clean it with a brush and soapy water to prevent odor buildup.
- Grind Chamber: To clean the grind chamber, grind small pieces of citrus peels (lemon, orange) with cold water. This helps to freshen the disposal.
- Stainless Steel Components: The stainless steel grind ring and swivel impellers are designed for durability and resistance to corrosion. No special maintenance is required for these components beyond regular use and cleaning.
