5.4 Filling and Bleeding

- Close the air vent plug once water starts to emerge steadily.
- Check all connections for leaks.
6. Operation
6.1 Central Heating Operation
The BERNSTEIN R18W radiator operates as part of your existing central heating system. Adjust the heat output using the radiator valves (not included) or your central heating thermostat.
6.2 Electric Operation (Optional)
This radiator can be converted for electric-only operation by installing a suitable electric heating element (not included) and filling it with a heat transfer fluid. This modification must be carried out by a qualified electrician and plumber, adhering to all electrical safety standards.
7. Maintenance
7.1 Cleaning
Clean the radiator regularly with a soft, damp cloth. For stubborn marks, a mild soap solution can be used. Rinse thoroughly and dry immediately. Avoid abrasive cleaners, scouring pads, or chemical solvents as these can damage the finish.
7.2 Bleeding the Radiator
If the top of the radiator feels cold while the bottom is hot, it indicates trapped air. Bleed the radiator as described in Section 5.4 to ensure efficient operation.
7.3 Annual Checks
Periodically check all connections for any signs of leaks or corrosion. Ensure mounting brackets remain secure.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator not heating up fully (cold at top) | Trapped air | Bleed the radiator using the air vent plug. |
| Radiator not heating at all | Valves closed, central heating system off, or system fault | Check radiator valves are open. Ensure central heating system is operational. Consult a heating engineer if system fault is suspected. |
