Step 2: Install Drain Saddle (ADS1K)
It is highly recommended that you watch the video "How to Install iSpring Drain Saddle (ADS1K)
for Reverse Osmosis (RO) System | DIY Installation" on YouTube.
Step 2. a. Choose a proper spot anywhere before the P-trap on the drain pipe to install the drain
saddle and tubing. Remember that the drain saddle should NOT be installed after the P-trap
to prevent potential microorganism growth.
Step 2. b. Drill a 1 /4" hole in the drain pi
pe, and paste the black sticky pad around the hole.
Step 2. c. Cut the BLACK tubing end to make a 45° angle. Insert the tubing into the 1/4'' hole
in the drain pipe, install the back plate, and tighten the two screws with hex nuts while the
tubing remains in the hole.
Step 2. d. Insert Lock Clip. Pull the tubing lightly to make sure it is secure.
Step 3: Install the Vertical Filters: Stages 1, 2, and 3
Step 3. a. Make sure that the O-ring is seated inside the
groove at the top of the filter housing. Food-grade
silicone jelly m
ay help the O-ring stay in place and
seal better.
Step 3. b. Filter cartridges are preserved in shrink wrap.
Note the direction sign on the sticker before
removing the wrap.
Step 3. c. When placing the filter cartridge into its
housing, make sure it is centered, and the knob is
protruding from the bottom of the housing fits in the
central hole of the filter.
Step 3. d. Screw the housing, with filters attached, onto
the housing caps (caps are pre-assembled on the
machine head). The cap
also has a center knob that
should be inserted into the center hole of the filter
cartridge. Twist the housing on in a counter-clockwise direction by hand, and then use a
housing wrench to tighten it up for about 1/4 – 1/2 turn. Do not overtighten. This can cause
leaks and make it difficult to unscrew the housing when replacing 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, attaching to
the housing cap.
