Step 4: Installing the Vertical Filters: Stages 1, 2, and 3
4.1 Make sure the Oring is seated inside the groove on
top of the filter housing. (Figure 10). A light amount
of foodgrade silicon jelly may be used to help the
Oring seal better, but is not required.
4.2 The 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 preassembled 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 the housing wrench to tighten it another 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.
4.5 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 the end with the rubber washer faces
up, thereby attaching it to the housing cap.
Step 5: Installing the
Tank Shutoff Valve (TSV)
5.1 Wrap 10 15 wraps of Teflon tape clockwise (when looking from above) onto the metal thread
at the top of the tank.
5.2 Screw (clockwise) the Tank Shutoff Valve on and tighten it by hand. Do not over tighten.
5.3 Connect the
YELLOW
tubing
into the QuickFitting on the TSV.
Step 6: Installing the Reverse Osmosis Membrane
Figure 8
Figure 9
6.1 First, disconnect the white tube from the quickfitting connection on the membrane cap. This
will allow you to unscrew the membrane housing cap.
6.2 Unscrew (counter clockwise) and remove the membrane cap.
6.3 Remove the membrane from the vacuum sealed packaging. Following the flow direction sign
on the membrane, firmly insert it into the housing. The side with the two small black Orings
should be inserted first. When it is inserted fully and properly, the end of the membrane will be
even with the housing opening. See Figure 89.
