• Wiring Check: Periodically check all electrical connections for tightness and signs of wear or corrosion.
• Filter Maintenance: Ensure that the air filters in your main ventilation unit are regularly cleaned or replaced as per the unit's instructions. This prevents excessive dust from reaching the blower assembly.
