Operating Instructions

1. Initial Startup

1. Ensure all plumbing connections are secure and leak-free.
2. Open a hot water faucet to allow water to flow through the heater and purge all air from the system. This is crucial to prevent damage to the heating element.
3. Once water flows steadily from the faucet, close the faucet.
4. Turn on the electrical power at the circuit breaker.
5. The unit's LED display will illuminate.

2. User Interface and Temperature Adjustment

The unit features an LED digital display and intuitive touch controls.

• LED Display: Shows real-time water temperature and flow rate.
• Power Button: Press to turn the unit on or off.
• Up/Down Arrows: Use to adjust the desired water temperature (range: 85°F - 131°F).
• Temperature Auto-Recall: The unit remembers your last temperature setting.

3. Energy-Saving Smart Adjustment

The ECO065 utilizes frequency conversion thermostat technology to optimize energy consumption. It dynamically adjusts power output based on the real-time water flow and your set temperature. This reduces energy waste by lowering output during periods of reduced demand, eliminating the need for preheating and minimizing standby heat loss.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your water heater.

• Annual Inspection: It is recommended to have a qualified technician inspect the unit annually.
• Cleaning: Periodically wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Scaling Prevention: The cast aluminum heating core is designed to minimize scaling and mineral buildup. In areas with hard water, consider installing a water softener to further reduce mineral accumulation and maintain efficiency.
• Winterization (if applicable): If the unit is installed in an area prone to freezing and will not be used for an extended period, drain the water from the unit and pipes to prevent freeze damage. Turn off the power supply before draining.

Troubleshooting

Before contacting customer support, review the following common issues and solutions:

• No Hot Water:
  • Check if the power supply is on at the circuit breaker.
  • Ensure the unit is turned on via the power button.
  • Verify water flow. The unit requires a minimum flow rate to activate heating.
  • Check for error codes on the LED display (refer to specific error code meanings if available in future documentation).
• Insufficient Hot Water Temperature:
  • Increase the set temperature using the up arrow button.
  • Reduce the water flow rate at the faucet. Higher flow rates may result in lower outlet temperatures, especially with very cold inlet water.
  • Ensure the unit's wattage (6.5KW) is sufficient for your specific application and inlet water temperature. Refer to the flow rate map in the installation section.
• Water Leakage:
  • Immediately turn off the water supply and electrical power to the unit.
  • Inspect all plumbing connections for tightness.
  • If leakage persists, contact a qualified plumber or customer support.
• Unit Not Turning On:
  • Check the circuit breaker.
  • Ensure the power button on the unit is pressed.
