7. Maintenance ALWAYS ENSURE THAT THE MAIN EXTERNAL ELECTRICITY SUPPLY IS SWITCHED OFF BEFORE COMENCING ANY MAINTENANCE ON THIS HEATER. A single drop of light oil should be applied to the motor bearing from time to time. To obtain the best results from the heater, it is essential to avoid the accumulation of dust and dirt within the unit on the air inlet and discharge grilles. Other faults in relation to the element, motor and wiring should be identified using conventional fault finding techniques.
