3.4 Installation Steps (General Guidelines)

This section provides general installation guidance. Always refer to the detailed instructions provided in the physical manual and consult with qualified professionals.

1. Mounting: Securely mount the unit to a wall using the provided hardware. Ensure the mounting surface is capable of supporting the unit's weight.
2. Water Connections: Connect the cold water inlet and hot water outlet to your plumbing system using 1/2" NPT connections. Ensure all connections are watertight.
3. Electrical Wiring: Connect the electrical wiring according to the electrical requirements (240V, 6# AWG wire, 60 Amp DP breaker). This step must be performed by a licensed electrician.
4. Flush System: Before powering on, flush the water heater to remove any air from the system.
5. Power On: Once water is flowing and all connections are secure, turn on the electrical power at the circuit breaker.

4. Sizing Guide: Choosing the Right Model

To ensure optimal performance, select a tankless water heater model that matches your household's hot water demand and local incoming water temperature. The WN-13kW is designed for 1-2 points of use in mild to moderate climates.

Steps to Choose:

1. Determine Inlet Water Temperature: Identify the average inlet water temperature for your region. Colder temperatures require more power (kW) to heat water to the desired temperature.
2. Confirm Hot Water Demand: Assess how many fixtures (sinks, showers) will be used simultaneously.
3. Select Model: Use the sizing chart to find the model that best meets your demand based on inlet temperature and required flow rate.

5. Operation

5.1 Initial Startup

1. Ensure the unit is properly installed and all water and electrical connections are secure.
2. Open a hot water faucet in your home to allow water to flow through the unit for a few minutes, purging any air from the system.
3. Turn on the circuit breaker supplying power to the water heater.
4. The digital display on the unit should illuminate.

5.2 Setting Temperature

• Use the touch controls on the front panel to adjust the desired water temperature.
• The digital display will show the set temperature, which can range from 86°F to 140°F.

6. Maintenance

The WINTEMP tankless water heater is designed for low maintenance. Unlike traditional tank heaters, it does not store water, which prevents scale buildup and eliminates the need for regular flushing.

• External Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Inlet Filter Screen: Periodically check the inlet filter screen for debris. If clogged, turn off power and water supply, remove the screen, clean it, and reinstall.
• Professional Inspection: It is recommended to have a qualified professional inspect the unit annually to ensure optimal performance and safety.

7. Troubleshooting

If you experience issues with your WINTEMP WN-13kW tankless water heater, consider the following general troubleshooting steps. For persistent problems, contact customer support or a qualified technician.

• No Hot Water:
  • Check if the circuit breaker is tripped. Reset if necessary.
  • Ensure adequate water flow. The unit requires a minimum flow rate to activate.
  • Verify the temperature setting on the unit's display.
• Inconsistent Water Temperature:
  • Confirm that the inlet water temperature is within the unit's operating range for your climate.
  • Reduce simultaneous hot water usage if the unit is struggling to keep up with demand.
  • Check for any blockages in the water lines or the inlet filter screen.
