After the brackets are in place, carefully lift the water heater and slide it onto the brackets. Ensure that it's seated properly and that the brackets are supporting the unit's weight evenly. Double-check that the water heater is still level and make any necessary adjustments.

Finally, secure the water heater to the brackets using the provided hardware. This may include screws, bolts, or clips that attach to the heater and the brackets. Tighten these connections firmly to ensure the water heater is safely and securely mounted to the wall.

Electrical Connections: Connect the heater to a grounded outlet with the correct voltage and amperage rating

To ensure the safe and effective operation of your point-of-use electric water heater, it is crucial to establish proper electrical connections. This involves connecting the heater to a grounded outlet with the correct voltage and amperage rating. Here's a step-by-step guide to help you through the process:

• Identify the Correct Outlet: Locate a grounded outlet that matches the voltage and amperage requirements specified in your water heater's manual. Typically, point-of-use electric water heaters require a 120-volt, 15-amp circuit. Ensure the outlet is not overloaded with other appliances.
• Turn Off Power: Before making any electrical connections, turn off the power to the circuit at the main electrical panel. This is a critical safety measure to prevent electrical shock.
• Connect the Ground Wire: Attach the green ground wire from the water heater to the grounding screw on the outlet. This connection is essential for preventing electrical shock and ensuring the safe operation of the heater.
• Connect the Hot and Neutral Wires: Connect the black hot wire from the water heater to the brass screw on the outlet, and the white neutral wire to the silver screw. Ensure the connections are secure and there are no exposed wires.
• Use a GFCI Outlet: If the outlet is located near water sources, such as under a sink, it is recommended to use a Ground Fault Circuit Interrupter (GFCI) outlet. This type of outlet provides additional protection against electrical shock.
• Test the Connection: Once the connections are made, turn the power back on at the main electrical panel. Test the water heater to ensure it is operating correctly. If you experience any issues, such as the heater not heating water or tripping the circuit breaker, consult the troubleshooting section of the manual or contact a professional electrician.

By following these steps and ensuring proper electrical connections, you can help maintain the safety and efficiency of your point-of-use electric water heater.

Plumbing Connections: Attach the inlet and outlet pipes, ensuring proper alignment and secure fittings

Begin by identifying the inlet and outlet pipes on the electric water heater. The inlet pipe is typically located at the bottom of the unit, while the outlet pipe is positioned at the top. Ensure that the pipes are properly aligned with the corresponding connections on the water heater. Misalignment can lead to leaks or inefficient water flow.

Next, use Teflon tape or pipe thread compound to secure the fittings. This will help create a watertight seal and prevent any potential leaks. Tighten the fittings by hand, and then use a wrench to give them an additional half-turn. Be careful not to overtighten, as this can damage the threads or the fittings themselves.

If the pipes are not already connected to the water supply and drain, you will need to do so. Turn off the main water supply before connecting the inlet pipe to the water heater. Once connected, turn on the water supply and check for any leaks. If leaks are present, tighten the fittings or reapply Teflon tape as necessary.

For the outlet pipe, connect it to the drain or the next fixture in the line. Ensure that the connection is secure and that there are no leaks. If you are connecting the outlet pipe to a fixture, such as a sink or shower, make sure that the fixture is properly installed and that the water flow is adequate.

Finally, check the water heater's operation by turning it on and allowing it to heat up. Once the water has reached the desired temperature, turn on the faucet or fixture connected to the outlet pipe. The water should flow smoothly and without any leaks. If you encounter any issues, such as leaks or inadequate water flow, troubleshoot the connections and fittings as necessary.
