Nitrate/Nitrite Test Instructions
If you purchased your system specifically for nitrate reduction, Vertex recommends
testing with the kit supplied herein to establish that nitrate and nitrite are being reduced to
acceptable levels.
Werecommended tests be made on the filtered water each 6 months to assume it con-
forms. Open the PurTest package, take out one strip. Insert a strip in a sample of filtered
water for a few seconds, then withdraw and wait for 60 seconds. Color change on the end
pad is for nitrate, and the upper pad is for nitrite.
Replacement test kits may be purchased from your dealer.
Each 6 months, the water should be sent to a certified water laboratory, or to the coun-
ty for tests on the filtered water for any additional items of concern.

iNOTICE
This instruction manual was written to guide a professional plumber to make an easy
installation of the VERTEX Pure Water Machine. The installation shall conform to state
and local laws and regulations.
This manual covers systems with 36 allon per day membranes (PT-4.0, PT-4.0/P, PT-
4.0/5, PT-4.0/5/P) and systems with 50 gallons per day membranes (PT-4.0/50, PT-
4.0/P/50), PT-4.0/5/50, PT-4.0/5/P/50).
This filter system can be installed by the homeowner who has sufficient tools and
skills. Be cautioned that an extra faucet for purified water will be installed . This requires a
7/8-inch diameter hole in the sink top. If there is not an extra hole existing, a new one
must be drilled. For a porcelain sink, this requires a special drill (7/8" Relton cutter) which
costs about $160 and requires skill to use.

1.0 INTRODUCTION
The VERTEX Pure Water Machine is a 4-stage water cleansing system. The princi-
pal cleansing of the water of dissolved solids is by the Reverse Osmosis membrane filter
(stage 3).
Stage One is a sediment filter which removes particles of rust, sand and other trash in
the water line down to 5-microns in size.
Stage Two is an activated carbon block filter which removes odors, chlorine and for-
eign tastes.
Stage Three is an advanced reverse osmosis membrane for removal of dissolved solids.
This is the heart of the system. The reverse osmosis technology on average removes
95% of the dissolved solids. Dissolved solids are not removed by municipal water treat-
ment systems. This is why the Vertex Pure Water Machine is an important safety factor for
the water you drink and use in your cooking. Chemical contaminants such as chromium-
6, lead, nitrates, and selenium which seep into municipal water systems are removed.
The water pressure against the reverse osmosis membrane forces the water molecules
through the membrane, but the larger contaminant molecules are kept behind and are
flushed to the sewer.The clean water goes to the storage tank and is held there ready to use.
When the faucet is opened, clean water from the storage tank flows through the acti-
vated carbon polishing filter to the faucet for your use. The tank is prepressurized with a
bladder which pushes the water out through the final carbon filter.
A special faucet is installed on your sink which dispenses safe, good tasting drinking
water which is especially good for coffee, tea and drinks. By extending a line to your refrig-
erator, it can be used to make ice cubes.
LIFE. The filter life is specified by the number of gallons of water flowing through
the system. Normal household will use two to three gallons of purified water daily.The fil-
ters are good for 1500 to 3000 gallons total usage depending on water quality.Therefore
the filter elements, Stages 1,2, & 4 should be changed at least once a year. The Reverse
Osmosis membrane has a longer effective life-span (5-year maximum) and it should be
changed once every three years. See section 4.0
5-stage systems have an additional carbon pre-filter. All other stages are the same as
described above.

2.0 INSTALLATION
Before starting the installation, you should measure the water pressure that is avail-
able under the sink to power the Pure Water machine RO. If the pressure is less than 40-
psig, it is too low; and if it is 90-psig, it may be too high. The solution if the pressure
is too low is to use a model with a booster pump. The solution for high water pressure,
is to put a pressure regulator in the inlet water line to the house. A pressure of 60-75 psig
is normal.
2.1 Location of RO unit
The RO unit may be located under the kitchen sink or in the basement. A cold
water supply line must be close by. When locating the system under a sink make sure
there is adequate room for the filter module assembly as well as the storage tank. For
best performance the tank should be located as close to the clean water faucet (sup-
plied) as possible (within 20 feet).
2.2 Mounting the RO filter unit under a sink (Fig. 1.)
Mount the unit to the wall of the sink cabinet. Pre-fit the unit by positioning the bot-
tom of the pre-filter cartridges 2 inches off the floor of the cabinet. This clearance is nec-
essary to make room to remove the housings when replacing the filter cartridges. Mark
the location of the 2 mounting holes in the mounting bracket. Install 2 mounting screws
leaving 1/8 inch clearance under the screw head. Check the fit by mounting the RO filter
unit but don’t install yet.
A 1/4” ball valve is supplied so the homeowner can easily shut off feed water when
leaving the home unattended. The best overall protection from potential water leaks in the
kitchen, hot water heater, or utility room is to install an automatic leak detector shutoff
valve to the house (Vertex P/N LC-8021).

2.3 Install RO membrane element in housing (See Figure 2)
The RO membrane element is packed separately because the membrane has been
tested by the manufacturer and sealed in plastic with preservative. Remove the membrane
element from its sealed plastic bag. To install the membrane in the housing first loosen the
inlet fitting nut (the end of the housing with the single fitting) and remove the tube.
Unscrew the membrane housing cap. Notice that one end of the RO membrane has two
“O” rings on it. This end slides in first. Check that the “O” rings are tight and in their
grooves. Lubricate lightly with cooking oil or vaseline. Install the membrane so the black
sealing ring on the membrane is at the open end of the housing. Press the membrane in and
feel the two “O” rings seat in the housing. Make sure they seat properly on the barrel of the
housing, then reinstall the housing end cap and tighten securely.Reinstall the tubing and
fitting and secure fitting nut.
2.4 Connecting the feed water supply (Fig. 3)
The feed water assembly consists of 1/2” brass slip joint adapter,ablack wash-
er,and a 1/4” x 1/4” ball valve. Locate these parts in the installation kit.
Locate the cold water shut offvalve under the sink and turn it off. Open the cold
water faucet to release the pressure. On single handled faucets, the hot water may
have to be turned off to prevent any hot water cross-over. If water continues to come
out of the faucet with the under-sink valvesturned off, the house main valve will have
to be turned off.
With the water turned off, disconnect the cold water riser tube (flex line) from
the valve. Install the slip joint connector with the black washer. Loosen the nut and
separate the cold riser tube from the faucet shank. Gently bend the riser tube so that
the slip joint adapter fits onto the faucet shank. Reinstall the cold riser tube on the
slip joint connector using the existing cone washer. For Solid copper tube the proce-
dure is the same except you must cut a piece of the riser tube about 3/4” to 1” so the
slip joint adapter can fit between the valve and the riser tube. Wrap several turns of

teflon tape on the ball valve and install on the slip joint connector.
In some cases the Pure Water Machine is supplied with a saddle Valve which can
clamp over a copper pipe and make the hole and seal at once. (See figure 4).

2.5 Installation of drain connection (Fig. 5)
Place the drain outlet saddle on the drain pipe. Allow proper space for the drilling
operation. Tighten the saddle bolts evenly on both sides. Using the opening in the drain
outlet saddle as a guide, drill a 1/4” hole in the drain pipe. Clean any debris out of the drain
saddle connection.

2.6 Installation of clean water faucet (Fig. 6)
The faucet should be positioned
with aesthetics, function, and con-
venience in mind. An ample flat
area is required for the faucet base
so that it can be drawn down tight.
The space under the sink below
where the faucet will be mounted
must be clear of any obstructions.
Some conditions may eliminate
the need to drill a hole in the sink
such as a faucet previously
installed in the sink, a hole cov-
ered by a chrome hole cover, or an
unused spray handle. If any of
these situations are present, you
may mount the faucet in one of
these holes.
The sink drilling process is not
complicated, but requires a certain
amount of caution and fore-
thought. Porcelain sinks can be
chipped if care is not exercised
when drilling the hole for the
faucet.
[NOTE: This procedure is for the non air gap faucet provided.]
2.7 Porcelain/Enamel over Steel or Cast Iron Sinks
Using a small diameter carbide tipped drill, drill a pilot hole completely through the
porcelain and the material underneath. Remove any metal chips that fall into the sink to
prevent rust stains. Place the spring-loaded porcelain cutter bit in to the drill chuck. Make
sure the pilot guide is insertedtightly. Insert the pilot guide onto the pilot hole. Push down
gently on the drill motor to apply light pressure to the porcelain surface. Start the drill
motor, turning as slowly as possible. After the initial cut has started, motor speed may be
gradually increased. The cut may require three to four minutes to complete. Going faster
could result in excessive chipping. Be sure a complete ring has been cut through the porce-
lain to the metal underneath.
Place the finish hole saw into the drill chuck. Make sure the pilot guide is inserted
tightly. Insert the pilot guide into the pilot hole. Begin cut using a slow speed and light
pressure until the porcelain has been penetrated to the material underneath. Remove the
saw from the hole and clean all debris from the porcelain surface. Reinsert saw into the
hole and cut through the remaining material.
