- Structurally sound to support the weight of the unit when full (approx. 67 kg).
- Protected from freezing temperatures.
- Easily accessible for maintenance.
- Close to the main hot water demand points to minimize heat loss.
4.3. Dimensions and Mounting
Refer to the dimension diagram for precise measurements and mounting hole distances. The unit has a product height of 770 mm, width of 385 mm, and depth of 385 mm. The distance between the wall mounting screws is 200 mm.

4.4. Plumbing Connections
Connect the cold water inlet and hot water outlet pipes. Install the provided safety valve on the cold water inlet. Ensure all connections are watertight. Anti-electrolysis sleeves are recommended to prevent galvanic corrosion.
4.5. Electrical Connection
Connect the water heater to a dedicated electrical circuit as per local electrical codes. Ensure the power supply matches the unit's requirements (1500 Watts, 1000 Volts as per specifications, though typical household voltage is 230V). A qualified electrician must perform this step.
5. Operating Instructions
5.1. Filling the Tank
Before switching on the power, ensure the water heater tank is completely filled with water. Open a hot water tap in your home to allow air to escape until water flows steadily.
5.2. Power On
Once the tank is full, switch on the electrical power to the water heater.
5.3. Temperature Adjustment
The water heater features an adjustable thermostat with a temperature range of 30°C to 75°C. Use the control knob, typically located at the bottom or front of the unit, to set your desired water temperature. The integrated thermometer will indicate the current water temperature.
5.4. Automatic Operation
The water heater will automatically heat the water to the set temperature and maintain it. The unit includes protection against overheating and dry heating, automatically shutting off if these conditions are detected.
6. Maintenance
Regular maintenance ensures the longevity and efficiency of your Teka EWH 50 C water heater.
- Magnesium Anode Inspection: The magnesium anode protects the tank from corrosion. It should be inspected and replaced periodically (typically every 1-2 years, depending on water quality) by a qualified technician.
- Drainage: If the water heater will not be used for an extended period or if there is a risk of freezing, drain the tank completely.
- External Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Safety Valve Check: Periodically check the safety valve to ensure it is not blocked and functions correctly.
7. Troubleshooting
If you encounter issues with your water heater, refer to the following common problems and solutions. For complex issues, contact a qualified technician.
- No Hot Water:
- Check if the power supply is on.
- Verify the thermostat setting. Ensure it is not set too low.
- Check if the circuit breaker has tripped.
- Ensure the tank is full of water. - Insufficient Hot Water:
- The thermostat setting might be too low.
- High hot water demand exceeding the unit's recovery rate.
- Sediment buildup in the tank (requires professional cleaning). - Water Leaks:
- Check pipe connections for tightness.
- The safety valve may be discharging due to excessive pressure (normal operation, but if continuous, check water pressure).
- For leaks from the tank itself, immediately turn off power and water supply and contact a technician. - Unusual Noises:
- Hissing or popping sounds can indicate sediment buildup on the heating element. This requires professional descaling.
