4.2 Plumbing Connection
- Connect the water inlet and outlet pipes to the unit. The unit uses 1/2" NPT fittings.
- Ensure all connections are watertight to prevent leaks. Use appropriate sealing materials (e.g., Teflon tape or pipe dope) on threaded connections.
- The inlet is typically marked in blue, and the outlet in red.

4.3 Electrical Connection
IMPORTANT: Electrical installation must be performed by a licensed electrician.
- The ECO65S requires a 240V electrical supply.
- It needs a dedicated 1x30AMP Double Pole Breaker.
- Use 10AWG/2 wires with Grounding for proper installation.
- Connect the unit's power cord directly to the dedicated circuit breaker.
- Ensure all electrical connections are secure and comply with local codes.

5. Operating Instructions
5.1 Initial Startup
- Before turning on power, ensure the unit is filled with water by opening a hot water faucet until water flows steadily. This purges air from the system.
- Turn on the dedicated circuit breaker for the water heater.
- The digital display on the unit will illuminate.
5.2 Setting Water Temperature
- Use the touch controls on the front panel to adjust the desired outlet water temperature.
- The unit can heat water up to 131°F (55°C).
- The digital display shows the set temperature and actual outlet temperature.

5.3 Self-Modulation Technology
The ECO65S features self-modulation technology, which intelligently adjusts power input during heating to maintain a stable output temperature and optimize energy consumption. This ensures a consistent hot water flow without significant temperature fluctuations.

5.4 Flow Rate Considerations
The actual hot water output and temperature rise depend on the inlet water temperature and flow rate. The ECO65S is generally recommended for a single faucet or similar fixture requiring less than 1.0 GPM in northern regions, and potentially two faucets in southern regions. Refer to the chart below to determine the appropriate flow rate for your desired outlet temperature based on your geographical location's inlet water temperature.

6. Maintenance
The ECOTOUCH ECO65S tankless water heater is designed for minimal maintenance. Its cast aluminum heating elements are separated from the water lines, which significantly reduces scale buildup and corrosion. This design allows for virtually zero maintenance for years under normal operating conditions.
- Periodic Inspection: Annually inspect the unit for any visible signs of leaks or damage to the plumbing and electrical connections.
- Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Water Quality: In areas with hard water, periodic flushing of the system may be beneficial, though less critical than with traditional tank heaters due to the design. Consult a qualified plumber if you suspect significant mineral buildup.
7. Troubleshooting
This section addresses common issues you might encounter with your ECOTOUCH tankless water heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water or unit not turning on. | No power supply; circuit breaker tripped. | Check the dedicated circuit breaker and reset if tripped. Ensure the unit is properly connected to the power supply. |
| Water is not hot enough. | Inlet water temperature too low; flow rate too high; temperature setting too low. | Increase the temperature setting on the unit. Reduce the water flow rate at the faucet. Refer to the flow rate chart in Section 5.4 to ensure your flow rate is appropriate for your inlet water temperature. |
| Unit randomly shuts off. | Possible flow sensor or temperature sensor issue; internal safety mechanism triggered. | If the unit shuts off without an error code, try resetting the main power button on the unit or the circuit breaker. If the problem persists, contact customer support. |
| Water leakage. | Loose plumbing connections; damaged seals or fittings. | Immediately turn off the water supply and electrical power to the unit. Inspect all plumbing connections for tightness. If leaks persist, contact a qualified plumber or customer support. |
| Clicking sound during operation. | Normal operation of internal relays. | This is a normal operational sound for many tankless water heaters and does not indicate a defect. |
If you encounter issues not listed here or if the suggested solutions do not resolve the problem, please contact ECOTOUCH customer support.
