Setup and Installation

The Midea D15-25VI Electric Water Heater is designed for indoor, wall-mounted installation. For safety and proper function, professional installation by a certified technician is mandatory.

Installation Steps (Overview):

1. Site Selection: Choose a suitable wall location that can safely support the weight of the water heater when full (approximately 15 kg for water + unit weight). Ensure adequate space for maintenance and proper ventilation.
2. Mounting: Securely mount the water heater to the wall using the provided mounting bracket and appropriate fasteners for your wall type.
3. Plumbing Connections: Connect the cold water inlet (blue ring) and hot water outlet (red ring) pipes. Install the pressure relief valve (safety valve) on the cold water inlet line as per local plumbing codes.
4. Electrical Connection: Connect the unit to a dedicated 220 Volt, properly grounded electrical circuit. Ensure all electrical connections are secure and comply with local electrical codes.
5. Filling the Tank: Before powering on, open a hot water faucet in your home to allow air to escape and the water heater tank to fill completely with water. Close the faucet once water flows steadily from it.
6. Initial Power-Up: Once the tank is full, turn on the main power supply to the unit.

Important: Do not power on the water heater before the tank is completely filled with water. Operating an empty tank will damage the heating element and void the warranty.

Operating Instructions

Powering On/Off:

After successful installation and filling, turn on the main power switch connected to the water heater. The unit will activate and begin heating water according to the selected temperature setting.

Temperature Adjustment:

Use the temperature control dial located on the front panel to set your desired water temperature. Rotate the dial clockwise to increase the temperature and counter-clockwise to decrease it. The dial typically ranges from 'OFF' to 'MAX' or specific temperature indicators.

Xpress Heating Mode:

To activate the rapid heating function, turn the control dial to the 'Express' setting. This mode prioritizes quick heating to provide hot water faster. Once the desired temperature is reached, the unit will revert to standard heating or maintain the temperature.

Bacteria Defense System:

The Full-path Bacteria Defense System operates automatically to maintain water hygiene. No specific user action is required for this feature to function.

Maintenance

Regular maintenance is crucial for the efficient operation and longevity of your Midea D15-25VI Electric Water Heater.

• Annual Inspection: It is highly recommended to have a qualified technician inspect the water heater annually. This inspection should include checking the heating element, anode rod (for the Ti+ Saphir Enamel Tank), and the safety valve.
• Draining the Tank: If the water heater will not be used for an extended period (e.g., during vacations) or if there is a risk of freezing, the tank should be drained completely. Consult a professional for the correct draining procedure.
• Exterior Cleaning: Wipe the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
• Safety Valve Test: Periodically test the temperature and pressure relief (T&P) valve by lifting the test lever. Ensure water flows out and the valve reseats properly. Follow manufacturer guidelines for frequency.

Troubleshooting

Before contacting customer service, please review the following common issues and their potential solutions:

• No Hot Water:
  • Check if the main power supply to the water heater is on.
  • Ensure the temperature setting on the control dial is not set to 'OFF' or too low.
  • Verify that the circuit breaker for the water heater has not tripped.
  • The Overheat Protection may have activated. Allow the unit to cool down and consult the full product manual for instructions on how to reset it, if applicable.
• Insufficient Hot Water:
  • The demand for hot water might exceed the unit's 15-liter capacity. Allow more time for reheating.
  • The temperature setting might be too low. Increase the temperature setting.
  • Sediment buildup in the tank can reduce heating efficiency. Professional descaling may be required.
• Water Leaks:
  • Immediately turn off the water supply and electrical power to the unit.
  • Check all plumbing connections for tightness.
  • If the leak originates from the tank itself, professional repair or replacement may be necessary.
• Unusual Noises (e.g., popping, rumbling):
  • These sounds often indicate sediment buildup at the bottom of the tank. Professional flushing and descaling can resolve this.
