Lift the new disposal up to the mounting ring. Align the three tabs on the disposal with the ramps on the mounting ring and turn the disposal clockwise until it locks into place. Use pliers or the provided wrench to tighten the locking ring for a secure fit. Next, install the discharge elbow using the supplied gasket and screws. Reconnect the P-trap to the discharge elbow and tighten the slip nuts. Finally, connect the dishwasher drain hose to the dishwasher inlet and secure it with a hose clamp.

FAQs
What are the most critical safety steps to take before starting to disconnect the old dishwasher?
Always turn off the water supply valve leading to the dishwasher and cut power at the circuit breaker first. This prevents potential leaks, electrical shocks, and damage while working with water lines and electrical connections.
What are the most common causes of leaks when connecting the hot water supply line and drain hose, and how can I prevent them?
Leaks often stem from improperly tightened connections or insufficient Teflon tape on threaded fittings. Ensure fittings are hand-tightened, then turn an additional 1/2 to 1 full turn with a wrench, and apply Teflon tape only to male threaded connections to create a watertight seal.
The project is listed as 'beginner' with an estimated 5 hours; is this realistic for someone with no plumbing experience, and what factors might extend the timeline?
While beginner-friendly, 5 hours is an estimate for straightforward installations. If you encounter seized fittings, rusted pipes, or need to adjust cabinetry, it could take longer. Having all tools and materials ready beforehand will help keep you on track.
Besides the listed tools, what other items should a beginner have on hand in case of unexpected issues during removal or installation?
A small shop-vac for unexpected spills is invaluable. Additionally, having a utility knife to cut the drain hose to length and possibly a basin wrench if the old water supply connection is in a very tight spot could save you a trip to the hardware store.
