of the Pre-Filter.
6. Over the sink, insert the outlet nipple of the Inlet Assembly into the other end of the
Back-Flush Adapter.
7. Have a second person switch the diverter valve to the filtering position and turn on the
water. There will be a small amount of back pressure forcing the Inlet Assembly out of
the Back-Flush Adapter so you must hold the Inlet Assembly, Back-Flush Adapter, and
Pre-Filter together to keep pressure on it and keep them from coming apart.
8. Allow the water to run for 5 minutes, shake the cartridge and tap it against the sink
until the flow rate has increased.
