4. Setup and Assembly
Follow these steps to prepare your radiator for use:
- Unpack: Carefully remove the radiator from its packaging. Retain packaging for storage if needed.
- Attach Castors: The radiator is supplied with castors for mobility. Turn the radiator upside down. Attach the castor assemblies to the base of the radiator using the provided screws or clips, ensuring they are securely fastened. Return the radiator to an upright position.
- Placement: Place the radiator on a firm, level surface. Ensure there is at least 50cm (20 inches) clearance from walls, furniture, and curtains to allow for proper heat circulation and prevent fire hazards. Do not place the radiator directly below a power outlet.
- Power Connection: Ensure the radiator is switched off (all power switches in the '0' position) before plugging it into a suitable 230V electrical outlet.

5. Operating Instructions
To operate your Sealey RD2500 Oil Filled Radiator:
- Plug In: Ensure the radiator is securely plugged into a grounded 230V electrical outlet.
- Set Thermostat: Turn the thermostat dial to the maximum ('HIGH') setting. This will allow the radiator to begin heating immediately.
- Select Heat Output: Use the power switches (I and II) to select the desired heat output:
- Switch 'I' ON: Low heat setting.
- Switch 'II' ON: Medium heat setting.
- Both 'I' and 'II' ON: High heat setting (2500W).
- Adjust Thermostat: Once the room reaches your desired temperature, slowly turn the thermostat dial counter-clockwise until you hear a click. The radiator will now cycle on and off to maintain this temperature. If the room temperature drops, the radiator will automatically turn on. If it rises, it will turn off.
- Switching Off: To turn off the radiator, switch both power switches (I and II) to the '0' position and then unplug the unit from the wall outlet.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your radiator.
- Cleaning: Always unplug the radiator and allow it to cool completely before cleaning. Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish. Ensure no water enters the internal components.
- Storage: If storing the radiator for an extended period, ensure it is clean and dry. Coil the power cord neatly. Store the unit in a cool, dry place, preferably in its original packaging, to protect it from dust and damage.
- Inspection: Periodically inspect the power cord and plug for any signs of damage. If damage is found, do not use the radiator and contact a qualified service technician.
7. Troubleshooting
If you encounter issues with your Sealey RD2500 radiator, refer to the table below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator does not turn on. | No power supply. Thermostat set too low. Tip-over switch activated. | Check if plugged in and outlet is working. Turn thermostat to a higher setting. Ensure radiator is upright on a stable surface. |
| Radiator is not heating sufficiently. | Heat output setting too low. Thermostat set too low. Room is too large for the heater. | Select a higher heat output (both switches ON). Increase the thermostat setting. Consider using additional heating or a more powerful unit for larger spaces. |
| Radiator emits unusual noise or smell. | New unit (initial smell). Internal fault. | A slight odor is normal for new heaters during first use; it should dissipate quickly. If noise or smell persists or is strong, unplug immediately and contact customer support. |
| Radiator repeatedly turns off. | Overheating protection activated. Tip-over switch activated. | Ensure radiator is not covered and has adequate ventilation. Allow to cool before restarting. Ensure radiator is upright on a stable surface. |
If the problem persists after attempting these solutions, please contact Sealey customer support.
