For best results the GC-747 System's GreaseDiapers® should be replaced regularly.  GreaseDiapers® are easy to replace and takes just minutes. GreaseDiapers® should be replaced as needed depending on the volume of Fats, Oil and Grease (FOG) that is being generated. In a heavy grease environment you may need to use more than one GreaseDiapers® depending on the pattern of the grease spill. To replace the GreaseDiapers®, carefully unfasten the adjustable tension cord holding both ends of the cord. Remove the soiled  GreaseDiapers® replacing it with a new one. Note, always notify your duct cleaning company of any new equipment being installed. Special precautions will need to be taken during scheduled duct cleanings.

CAUTION: GreaseDiapers® could be damaged if they come in direct contact with hot water, high pressure and degreasers/cleaners. Therefore, the GreaseDiapers® should be removed during each cleaning and reinstalled. When using the GC-747 always make sure to check with local authorities for approval of application.
