DIRECTIONS FOR USE:Truck-mounted Machines: To prepare truck-mounted solution, add 1/2 litre of Fabririnse to 25 litres of water. Metre Fabririnse at a dilution of 1:10 with water through the venturi feed (overall dilution of 1:500 with water). Portable Machines: To prepare a ready-to-use solution, add 1/3 cup (100mls) of Fabririnse to 5- litres of water. pH Control: To determine the Fabrisinse is being used at the correct dilution ratio the pH of the effluent water should be measure using pH papers. The pH of the effluent water should be 6.0 to 7.0. If the pH is below 6 then the concentration of Fabririnse should be reduced. If the pH is above 7.0 then the concentration of Fabririnse should be increased.
