5. Setup and Installation
The EcoSmart ECO MINI 1 is designed for easy installation, typically under a sink for point-of-use applications. It plugs into a standard 120V outlet.
5.1 Plumbing Connections
- Turn off the main water supply before starting.
- Connect the cold water supply line to the inlet of the water heater.
- Connect the hot water outlet of the water heater to the hot water faucet line.
- Install the included pressure relief valve on the designated port. Ensure it is properly oriented and routed to a suitable drain or collection point.
- Important Note: The unit has 1/2-inch connectors. If your existing plumbing uses 3/8-inch lines, you will need appropriate adapters (e.g., 3/8-inch compression to 1/2-inch FIP). Ensure secure, leak-free connections using plumber's tape or sealant as needed.
- Once all connections are made, slowly turn on the cold water supply to fill the tank. Open a hot water faucet to allow air to escape until a steady stream of water flows. Check for leaks.
5.2 Electrical Connection
- Ensure the tank is completely filled with water before connecting to power.
- Plug the appliance line cord into a standard 120V grounded electrical outlet.

- Power On: Once the unit is filled with water and plugged in, the power indicator light will illuminate.
- Temperature Adjustment: Use the front-mounted knob to set the desired water temperature. Rotate clockwise to increase temperature and counter-clockwise to decrease.
- Heating Indicator: The heating indicator light will turn on when the unit is actively heating water and turn off once the set temperature is reached.
- The unit will cycle on and off as needed to maintain the set temperature.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your water heater.
- Temperature Setting: For units that are not used frequently or for extended periods, it is recommended to keep the temperature setting at the highest level to prevent the growth of bacteria, such as Legionella, within the tank.
- Drainage: Periodically drain the tank to remove sediment buildup. Turn off power and water supply, then open a hot water faucet and the pressure relief valve to drain.
- Inspection: Regularly inspect the unit for any signs of leaks, corrosion, or damage to the power cord.
- Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
8. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power; thermostat set too low; heating element failure | Check power connection and circuit breaker; adjust thermostat; contact support for element replacement. |
| Water not hot enough | Thermostat set too low; excessive hot water demand | Increase thermostat setting; allow time for recovery. |
| Water leaking from unit | Loose plumbing connections; faulty pressure relief valve; fractured tank | Tighten connections; inspect/replace pressure relief valve; if tank is fractured, unit needs replacement. |
| Pressure relief valve dripping | Normal thermal expansion; excessive water pressure | This can be normal. If excessive, consider installing an expansion tank or pressure reducing valve. |
