Step 3: Installing the Drain Saddle
3.1 Choose a spot on the drain pipe that is convenient for installing the drain saddle and tubing. It
is recommended that you install in a horizontal pipe to minimize dripping sounds.
3.2 Drill a 1 /4” hole on the drain pipe; paste the black sticky pad around the hole.
3.3 Cut the WHITE tubing end to make a 45 degree angle. Slip the plastic nut and front plate on
the tubing. Insert the tubing into the 1/4” hole on the drain pipe, install the back plate and
tighten the two screws with hex nuts while the tubing remains in the hole.
3.4 Tighten the nut securing the white drain line to the Drain Saddle by hand. Pull the tubing to
check if it is secure.
Step 4: Installing the Vertical Filters:
Stages 1, 2, and 3
4.1 Make sure that the O-ring is seated inside the
groove on the top of the filter housing. Food-grade
silicon jelly may be used to help the O-ring stay in
place and seal better.
4.2 Note the direction sign on the sticker before
removing the shrink wrap (GAC at 2
nd
stage.)
4.3 Rinse the GAC and CTO cartridges with tap water
for 5 minutes or until water is clear.
4.4 When placing the filter cartridge into its housing,
make sure it is centered and the knob protruding
from the bottom of the housing fits in the center
hole of the filter.
4.5 Screw the housing, with filters inserted, onto the housing caps (caps are pre-assembled on the
machine head). The cap also has a center knob which should be inserted into the center hole of
the filter cartridge. Twist the housing on in a clockwise direction by hand, and then use a
housing wrench to tighten it for about 1/4 – 1/2 of a turn. Do not over tighten. This can cause
leaks and make it difficult to unscrew the housing when replacing filters.
4.6 Follow steps 1.1 – 1.4 to install the GAC and CTO filters. *Note* the second stage GAC is the
only filter that must go in a certain direction. Make sure that the end with the rubber washer
faces up, thereby attaching to the housing cap.
Step 5: Installing the Tank Shut-off Valve (TSV)
5.1 Screw (clockwise) the Tank Shut-off Valve on and tighten by hand. Do not over tighten.
5.2 Connect the YELLOW tubing onto the Quick-Fitting of TSV.
