Frequently Asked Questions - JT74L400222 Jocel

How do I set the desired water temperature?

Turn the thermostat dial on the bottom front of the boiler to your preferred temperature, typically between 30°C and 75°C. Wait for the heater to reach the set point; the indicator light will turn off.

What should I do if the boiler doesn't heat water?

First, check the power supply and ensure the circuit breaker is on. Then verify the thermostat is set above room temperature. If still not heating, the heating element or thermostat may be faulty; contact a qualified technician.

How often should I descale the boiler?

It is recommended to descale the boiler annually, especially in hard water areas. Use a descaling solution suitable for electric water heaters, following the manufacturer's instructions.

Why is water leaking from the pressure relief valve?

Small drips during heating are normal as water expands. If continuous leakage occurs, the pressure may be too high or the valve faulty. Check the pressure and replace the valve if necessary.

Can I install the boiler myself?

Installation should only be carried out by a qualified professional in accordance with local regulations. Improper installation can result in electric shock, fire, or water damage.

What does the magnesium anode do?

The magnesium anode protects the steel tank from corrosion by attracting corrosive elements. It should be inspected every 1-2 years and replaced when depleted.

How do I reset the overheat protection?

If the boiler overheats, the overheat protector will trip. Turn off the power, allow the boiler to cool down, then press the reset button (usually red) located near the thermostat. If it trips again, call a technician.

The water is too hot / too cold. How to adjust?

Adjust the thermostat dial. For cooler water, turn clockwise towards lower numbers; for hotter, turn anti-clockwise. Wait 30 minutes for temperature to stabilize.

What is the maximum working pressure?

The maximum working pressure is 0.8 MPa (8 bar). Do not exceed this limit. If your system pressure is higher, install a pressure reducing valve before the boiler.

How do I drain the boiler for maintenance?

Turn off power and water supply. Attach a hose to the drain valve at the bottom of the boiler, open the valve and a hot water tap to allow air in. Drain completely. Close valve and refill before restoring power.
