Follow the same procedures as for changing the Stage-2 carbon filter. They are identical 10” carbon filters.
To remove the Pure water output line, first use a pair of pliers and remove the tubing lock (red clip) from
Point K (See Figure G).
Use a flat head screwdriver to push and hold the collet ring into the stage 4 filter. Then pull out the pure
water line. Discard the old filter and reconnect pure water line to new filter. Make sure the Flow direction
“arrow ” on the filter is pointing towards the right direction (See Figure H).
