Installation Instructions
The thermoflow UT10N2 is designed for point-of-use installation, typically under a sink or on the floor. Ensure the installation location is protected from freezing temperatures and has adequate drainage.
1. Site Selection
- Choose a location close to the hot water tap to minimize heat loss and waiting time.
- Ensure the surface can support the weight of the water heater when full (approximately 35 lbs).
- Maintain required clearances around the unit for ventilation and service access.
2. Plumbing Connections
The unit features 1/2 inch NPT water connections. The blue port is for cold water inlet, and the red port is for hot water outlet.
Important: A Temperature and Pressure (T&P) relief valve must be installed on the cold water inlet line, as shown in the diagram below, to prevent excessive pressure and temperature buildup. Use thread sealant on all threaded connections.

3. Filling the Tank
Before connecting power, open a hot water faucet in your system to allow air to escape. Then, open the cold water supply valve to the water heater. The tank is full when a steady stream of water flows from the hot water faucet. Do not apply power until the tank is completely filled.
4. Electrical Connection
The thermoflow UT10N2 operates on 120 Volts and requires a 1.5 kW power supply. It comes with a 2.6ft cord for plug-in use. Ensure the electrical outlet is properly grounded and rated for the appliance's power requirements (13A nominal current). Avoid using extension cords.

Operation
Once installed and filled with water, plug in the water heater. The unit features an adjustable temperature setting dial and a working indicator light.
Temperature Adjustment
The temperature control dial allows you to set the desired water temperature between 45°F and 167°F. The "Energy-Saver Mode" typically sets the temperature to approximately 165°F (±75°C). The red working indicator light illuminates when the heating element is active and turns off once the set temperature is reached.

Maintenance
Regular maintenance ensures optimal performance and longevity of your water heater. Always disconnect power before performing any maintenance.
- Temperature and Pressure Relief Valve: Manually operate the T&P relief valve at least once a year to ensure it is functioning correctly. Follow the manufacturer's instructions for the valve. This helps prevent pressure buildup.
- Draining the Tank: If the unit will be unused for an extended period or if there is a risk of freezing, drain the tank completely. Disconnect power, close the cold water inlet valve, open a hot water faucet, and drain the tank through the T&P valve or a dedicated drain valve if installed.
- Cleaning: Periodically wipe the exterior of the unit with a damp cloth. Do not use abrasive cleaners or solvents.
