Step 3: Install Drain Saddle
3.1 Choose a spot on the drain pipe that is convenient for installing the drain saddle and tubing. Horizontal pipe
is recommended to minimize the dripping sound.
3.2 Drill a 1 /4" hole on the drain pipe; paste the black sticky pad around the hole.
3.3 Cut the
BLACK
Insert the tubing into the 1 / 4" hole on the drain pipe, install the back plate and tighten two screws with hex
nuts while the tubing remains in the hole.
3.4 Tighten the nut on the Drain Saddle by hand. Pull the tubing to check if it is secure.
Step 4: Install the Vertical Filters: Stages 1,
2, and 3
4.1 Make sure that the O-ring is seated inside the groove on top
of the filter housing. (Figure 10). Food-grade silicon jelly
may be used to help the O-ring stay in place and seal better.
4.2 Filter cartridges are preserved in shrink wrap. Note the
direction sign on the sticker before removing the wrap
(GAC stage).
4.3 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 central hole of the filter.
4.4 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 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 up for about 1/4 – 1/2 turn. Do not
over tighten. This can cause leaks and make it difficult to unscrew the housing when replacing filters.
Follow the steps 1.1 – 1.4 to install the GAC and CTO filters. *Note* the second stage GAC is
4.5
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: Install Tank Shut-off Valve (TSV)
5.1 Wrap 10 - 15 turns of Teflon tape clockwise (looking from top) onto the metal thread at the top of the tank.
5.2 Screw (clockwise) the Tank Shut-off Valve on and tighten up by hand. Do not over tighten.
Connect the YELLOW tubing onto the Quick-Fitting of TSV.
