Frequently Asked Questions - TNC-15 COINTRA
How do I install the Cointra TNC-15 water heater?
Installation must be carried out by a qualified technician. The water heater should be mounted on a solid wall using the supplied brackets. Ensure the water supply and electrical connections meet local regulations. Set the safety valve correctly and fill the tank before switching on.
What is the recommended temperature setting for daily use?
For energy savings and to prevent scale formation, set the thermostat to 60 °C. This is sufficient for normal use. For higher temperature needs, you can adjust up to 75 °C, but this increases energy consumption.
How long does it take to heat the water to maximum temperature?
With a 1500 W heating element, a full 15-litre tank heats from 15 °C to 60 °C in approximately 30 minutes. Time may vary depending on the incoming water temperature.
What should I do if water leaks from the safety valve?
A small amount of water dripping from the overpressure safety valve is normal during heating. If leak is continuous, the pressure may be too high or the valve is faulty. Check the pressure reducer and ensure the valve is not blocked. Contact a technician if problem persists.
How often should I replace the magnesium anode?
The magnesium anode protects the tank from corrosion. Depending on water hardness, it should be inspected annually and replaced every 1 to 2 years if more than 50% consumed.
Can the TNC-15 be installed horizontally?
Yes, the TNC-15 is designed for both horizontal and vertical mounting. However, the water connections and safety valve must be positioned correctly. Follow the instruction manual for proper orientation.
Is the water heater suitable for hard water areas?
The appliance has a vitrified inner tank and a replaceable magnesium anode which help resist scale and corrosion. In hard water areas, regular maintenance is essential. Use of a water softener is recommended.
What is the warranty period?
Cointra offers a 2-year manufacturer warranty on the water heater. The tank may have a separate warranty of up to 5 years if the anode is replaced regularly. Check your warranty card for details.
How do I drain the tank for maintenance?
Turn off the power and water supply. Attach a hose to the drain valve (if equipped) or disconnect the outlet pipe. Open the hot water tap to vent air. Drain completely before servicing. For TNC-15, follow the instructions in the user manual.
What does the safety thermostat do?
The safety thermostat cuts off power if the water temperature exceeds 90 °C. This prevents boiling inside the tank. It can be reset manually after the cause has been fixed.
