8. Once this is achieved, turn off the valve, disconnect the precarbon filter, and set it aside.
Place the Biosure filter into the head to the right of the sediment filter. Repeat flushing
process for the Biosure filter for at least 2 gallons.
9. Once complete, turn off the valve, disconnect the Biosure filter, and return it to its
original position. Prepare the RO filter (if using RO filter configuration) by removing the
cap and inlet plug, AND the plug at the bottom in the drain port.
10. Place the RO filter into the head to the right of the sediment filter. Remove the tube
cap, and connect the RO drain tube shown. Because the RO filter produces “brine” or
reject water in its filtration, ensure the RO Drain port on the back of the machine is
plumbed with ¼” LLDPE tubing to a drain or to the same bucket as the flush water.
Repeat flushing process for the RO filter for at least 2 gallons. (If UF Filtration is being
used, there will be a UF filter to flush instead of an RO filter and no drain is required).
