4. Setup and Installation
IMPORTANT: Installation must comply with all national, state, and local electrical and plumbing codes. Only licensed professionals should perform the installation.
4.1 Electrical Requirements
- Voltage: 240V
- Wattage: 14kW
- Amperage: Maximum 112.5 Amps
- Breaker: 3 x double-pole 40 Amp breakers (total 120 Amp setup).
- Wire Gauge: 3 x 8AWG wire gauge.
- Ensure your electrical panel can accommodate these requirements.
4.2 Plumbing Requirements
- Water Connections: 3/4" NPT.
- Minimum Flow Rate: The unit requires a minimum flow rate to activate heating.
- Install shut-off valves on both the hot and cold water lines for maintenance.
- Flush the water lines thoroughly before connecting to the unit to remove debris.
4.3 Mounting the Unit
- Select a suitable indoor location, protected from freezing temperatures and direct sunlight.
- Ensure adequate clearance around the unit for ventilation and service access.
- Use the provided hanging plate and screws to securely mount the unit to a sturdy wall surface.

4.4 Ground Water Temperature Considerations
The performance of a tankless water heater is influenced by the inlet water temperature. Colder inlet water will result in a lower maximum flow rate at a desired output temperature. Refer to the U.S. Ground Water Temp Map and usage guide to understand expected performance in your region.
Figure 6: U.S. Ground Water Temperature Map and Usage Guide. This map and accompanying table help determine the expected performance (maximum flow rate and simultaneous use) of the water heater based on regional inlet water temperatures.
5. Operating Instructions
5.1 Initial Startup
- After installation, ensure all water connections are secure and leak-free.
- Open a hot water faucet in your home to allow water to flow through the unit and purge any air from the system. Let water run for a few minutes.
- Turn on the electrical breakers for the water heater.
- The digital display will illuminate.
5.2 Temperature Adjustment
- The unit features a digital temperature display and control knob.
- To adjust the temperature, rotate the knob to your desired setting. The temperature range is typically 86°F to 140°F (30°C to 55°C).
- The display will show the set temperature, inlet temperature, outlet temperature, and flow rate.
- Press and hold the knob for 5 seconds to switch between Fahrenheit and Celsius.
