1. Check that power cord is properly connected to power pack and to outlet.2. Replace fuse or reset circuit breaker
2. Check for voltage at air cleaner outlet box If none, check fuse or circuit breaker at power input line.3. Replace Fuse.
3. Check that fuse in power pack is not blown4. Wash cells. If short is not corrected, call for service.
4. Check for shorted collecting cell by installing power door with collecting cells removed and only pre-filter installed. If green light turns ’ON" cell is shorted.5. Clean air sensor tube
5. Check for dirt or blockage in air sensor tube6. Replace damaged filter
6. Check that pre-filter is installed and not damaged.
