5. Operating Instructions
Follow these steps for safe and effective operation of your water heater.
5.1 Initial Start-up
- Before switching on, ensure the tank is completely filled with water. Open a hot water tap in your home until water flows steadily, indicating the tank is full and air has been purged.
- Plug in the water heater or switch on the dedicated power supply.
5.2 Temperature Adjustment
- Use the adjustable thermostat knob located on the front panel to set your desired water temperature.
- The LED indicator will illuminate to show the power on and heating function status.
- The maximum temperature setting is 72 degrees Celsius. For energy efficiency and safety, a setting between 45-55 degrees Celsius is often sufficient.
5.3 Child Safety Mode
Refer to the detailed instructions in the physical manual for activating and deactivating the Child Safety Mode to prevent accidental temperature changes.

6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater. Always disconnect the power supply before performing any maintenance.
6.1 Cleaning the Exterior
- 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 engineering thermoplastic body and the Bajaj AgeGuard coating which prevents color fading.
6.2 Descaling (Professional Service Recommended)
- Over time, mineral deposits (scale) can accumulate inside the tank and on the heating element, reducing efficiency.
- It is recommended to have the water heater descaled by a qualified technician annually, especially in areas with hard water.
- The Bajaj DuraCoat non-stick heating element is designed to resist scale buildup, but periodic inspection is still beneficial.
6.3 Anode Rod Inspection
- The Magnesium Anode rod protects the tank from corrosion. It should be inspected and replaced by a qualified technician every 1-2 years, depending on water quality.
7. Troubleshooting
Before contacting customer support, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power, thermostat set too low, heating element failure. | Check power supply. Adjust thermostat. Contact service if element suspected. |
