Manganese dioxide MnO2 which is insoluble characterized by a medium brown color and is found in expended PURAFIL media can usually be removed by normal washing 2 New unused PURAFIL media contains potassium permanganate KmnO or sodium permanganate NaMnO which is a strong oxidant and will react with and discolor any organic material with which it comes in contact These stains which will be brownish black in color may be removed using a solution of sodium bisulfite in water after the garment has been removed from the person However if the fiber has been damaged by the permanganate removal of the stain may make the damage more apparent CAUTION This procedure should start with a very weak solution gradually increasing the strength until the stain is removed Use of too strong a solution could conceivably cause additional fabric damage NOTE Sodium bisulfite gives of sulfur dioxide SO2 gas therefore it must be used in a well ventilated area 7 0 WARRANTY INFORMATION PURAFIL warrants hardware equipment manufactured by PURAFIL to be free from defects in material and workmanship under normal use and service for twelve 12 months from startup date or eighteen 18 months from shipment date PURAFIL S obligation under this warranty shall be limited to replacing any parts thereof which shall be demonstrated to have been defective THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES EXPRESS OR IMPLIED INCLU
