COMPONENT REPLACEMENT
Warning: To reduce the risk of fire, electrical shock or personal injury, always turn the unit “OFF” and
disconnect power cord from supply receptacle before removing the control panel, replacing the HEPA filter
and before cleaning or servicing the unit. This unit is equipped with an automatic restart motorized impeller
that will restart without warning after a temporary power interruption or recovery from a thermal overload
(over-heating) condition. Keep clear of the motorized impeller at all times to reduce the risk of injury.
Occasionally a defective component will cause the unit to operate improperly or not at all. Any electrical
component can fail. Refer to the Wiring Diagrams and Wiring Schematics to diagnose the failure of any
component. Diagnostics should only be performed by a technician qualified to service electrical equipment.
