Maintenance The only maintenance that is required for the heater is the periodic cleaning of the heater's electrostatic filter (located at the back of the unit). This cleaning should be performed at least once a month, or earlier as dust becomes visible on the filter, to ensure efficient operation of the heater. Cleaning the Electrostatic Filter Clean the filter often to provide for maximum performance. When necessary, wipe the cabinet clean with a soft damp cloth and/or furniture polish. Removing Filter Replacing Filter 1. Power the heater off by pressing the Power Button, located on the left side of the Control Panel. (Note: The sound of the heater's fans will continue until the heat has been completely vented, thus protecting the unit and preventing waste by cycling the remaining heat into the room. DO NOT unplug the heater until the sound of the fan has stopped. Doing so may cause damage to the unit.) 2. When the heater's fans have stopped (the heater will become completely silent) unplug the heater. 3. Release the Electrostatic Filter by pushing the filter up from below. 4. Remove the Electrostatic Filter by pulling the filter down and out. 5. Clean the filter by vacuuming the filter until clear. 6. Replace the filter by sliding the top upwards into the springloaded slot on the back of the heater, then gently press the bottom of the filter into place.
