2. Safety Information

WARNING: Electrocution Hazard

Before beginning any work on the electric installation, ensure that main breaker panel switches are "OFF" to avoid any danger of electric shock. All mounting and plumbing must be completed before proceeding with electrical hook-up. Where required by local, state, or national electrical codes, the circuits should be equipped with a "ground fault interrupter".

The unit must be properly grounded in accordance with state and local codes, or in absence of such codes, in accordance with national electric code or the Canadian electric code. Failure to electrically ground the product could result in serious personal injury or death.

Professional installation is recommended. Consult a certified electrician before purchasing and installing this unit to verify your electrical circuit can support high-power appliances. This is especially important if you already use other high-wattage devices (e.g., A/C, heater, oven).

Ensure the circuits and accessories meet all requirements:

• Power Requirement: 46 Amps
• Breaker Required: 50 Amp Double-Pole Breaker
• Wiring: 3 x 8 AWG wires (L1 x 1, L2 x 1, Ground x 1). Wire length should be determined based on installation position.

Confirm Your Circuit's Load Capacity:

A 150 Amp Household Service is recommended. Prevent circuit overloads for optimal performance and reliable operation of your equipment.

4. Operating Instructions

4.1. Commissioning the Water Heater

Note: Empty the water line air before starting the machine.

1. Open Water Inlet Valve: Open the water inlet ball valve to allow water to flow into the unit.
2. Purge Air: Open a hot water faucet in your home to exclude any air from the waterway. Conduct a sealing inspection of the waterway to check for leaks.
3. Turn on Circuit Breaker: Once water flows smoothly and all air is purged, turn on the circuit breaker in your domestic electric box. The display on the water heater should illuminate.
4. Adjust Temperature: Use the control knob on the unit to set your desired water temperature. The LED display will show the current temperature.

4.2. Smart Control (Wi-Fi & Voice)

This water heater is compatible with Alexa and Google Home. Download the Westinghouse app to connect your device and control water temperature remotely or via voice commands. Adjustments can be made in precise 1° increments from 86°F to 140°F.

5. Maintenance

Regular maintenance ensures the longevity and efficient operation of your tankless water heater.

• Cleaning: Regularly clean the exterior of the unit with a soft, damp cloth. Avoid abrasive cleaners.
• Filter Screen: Periodically check and clean the filter screen located in the inlet port to prevent debris buildup.
• Descaling: Depending on your water quality, periodic descaling may be necessary to remove mineral buildup from the heating elements. Consult a qualified plumber for descaling procedures.
• Leak Inspection: Regularly inspect all water connections for any signs of leaks. Address any leaks promptly to prevent damage.

5.1. Safety Thermal Cut-off Reset Instructions

If the product stops working due to triggering the safety thermal cut-off protection function, you can reset it to restore normal product operation.

Warning: Ensure to operate under power-off conditions.

1. Remove Outer Shell: Carefully remove the outer shell of the water heater.
2. Locate Safety Thermal Cut-off: Identify the safety thermal cut-off component inside the unit.
3. Press Reset Button: Using a screwdriver, press the reset button on the thermal cut-off.
4. Install Outer Shell: Reinstall the outer shell of the water heater.

To determine if the safety thermal cut-off has tripped, check the following: 1) The machine is not working (the display screen shows nothing). 2) The municipal power supply is normal (test whether other appliances at home are functioning properly). 3) The circuit breaker connected to the electric water heater has not tripped. If these three conditions are met simultaneously, the product's limiter may have tripped, and you will need to open the product cover to reset the safety thermal cut-off.

6. Troubleshooting

If you encounter issues with your water heater, refer to the following common troubleshooting steps. If the problem persists, contact customer support.

• No Hot Water: Check if the circuit breaker has tripped. Ensure the water inlet valve is fully open. Verify that the unit is powered on and the temperature setting is appropriate.
• Insufficient Hot Water: Ensure the flow rate is within the unit's capacity (up to 2.56 GPM). Check the inlet water temperature and adjust the set temperature if necessary. Refer to the "How to Choose the Right Model" chart for guidance on simultaneous usage.
• Water Temperature Fluctuations: Ensure stable water pressure. Check for air in the water lines.
• Unit Not Turning On: Verify electrical connections and ensure the circuit breaker is on. Check if the safety thermal cut-off has tripped (refer to Section 5.1).
• Leaks: Inspect all plumbing connections for tightness. If leaks persist, turn off water supply and power, then contact a qualified plumber.
