CLEANING AND MAINTENANCE INSTRUCTION
1. The electric heater should be cleaned regularly to wipe out the dust on
the surface of flanges. As this may influence the radiating efficiency.
2. Disconnect electricity supply and allow radiator to cool, wipe out dust
with a soft damp cloth. Do not use detergent or abrasives.
3. Do not scrap the surfaces of flanges with sharp hard tools, to avoid
surfaces getting rusty, because of damage of the paint coat.
