Nitrate/Nitrite Test Instructions
If you purchased your system specically for nitrate reduction, Vertex recommends testing with
the kit supplied herein to establish that nitrate and nitrite are being reduced to acceptable levels.
We recommended tests be made on the ltered water each 6 months to assume it conforms.
Open the PurTest package, take out one strip. Insert a strip in a sample of ltered 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 certied water laboratory, or to the county for tests
on the ltered water for any additional items of concern.

i NOTICE
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 gallon per day membranes (PT-4.0, PT-4.0/P, PT-4.0/5,
PT-4.0/5/P) and systems with 50 gallon per day membranes (PT-504, PT-504P, PT-505, PT-505P).
This lter system can be installed by the homeowner who has sufcient tools and skills. Be cau-
tioned that an extra faucet for puried 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 PureWaterMachine is a 4-stage water cleansing system. The principal
cleansing of the water of dissolved solids is by the Reverse Osmosis membrane lter (stage 3).
Stage One is a sediment lter 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 lter which removes odors, chlorine and foreign 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 treatment 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 ushed 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 ows through the activated carbon polishing lter
to the faucet for your use. The tank is prepressurized with a bladder which pushes the water
out through the nal carbon lter.
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 refrigerator,
it can be used to make ice cubes.
LIFE: The lter life is specied by the number of gallons of water owing through the
system. Normal household will use two to three gallons of puried water daily. The lters
are good for 1500 to 3000 gallons total usage depending on water quality. Therefore the
lter 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-lter. All other stages are the same as
described above.

2.0 INSTALLATION
Before starting the installation, you should measure the water pressure that is available 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 lter module assembly as well as the storage tank. For best
performance the tank should be located as close to the clean water faucet (supplied)
as possible (within 20 feet).
2.2 Mounting the RO lter unit under a sink (Fig. 1.)
Mount the unit to the wall of the sink cabinet. Pre-t the unit by positioning
the bottom of the pre-lter cartridges 2 inches off the oor of the cabinet. This
clearance is necessary to make room to remove the housings when replacing the
lter 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 t by mounting the RO lter 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).

Figure 2
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
rst loosen the inlet tting nut (the end of the housing with the single tting) 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 rst. 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 tting and secure tting nut.
2.4 Connecting the feed water supply (Fig. 3)
The feed water assembly consists of 1/2” brass slip joint adapter, a black washer,
and a 1/4” x 1/4” ball valve. Locate these parts in the installation kit.
Locate the cold water shut off valve 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 valves turned off, the house main valve will
have to be turned off.
With the water turned off, disconnect the cold water riser tube (ex 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 ts onto the faucet shank. Reinstall the cold riser tube on
the slip joint connector using the existing cone washer. For Solid copper tube the
procedure is the same except you must cut a piece of the riser tube about 3/4” to 1”
so the slip joint adapter can t between the valve and the riser tube. Wrap several
turns of teon 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 gure 4).

2.6 Installation of clean water faucet (Fig. 5)
The faucet should be positioned
with aesthetics, function, and
convenience in mind. An ample
at 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 covered 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 forethought.
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 inserted tightly. 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 porcelain to the metal underneath.
Place the nish 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.

2.8 Install Faucet (Fig. 6)
Disassemble the hardware from the threaded stud except for the top base plate and sealing
gasket. Install the faucet in the sink hole. From below the sink assemble the mounting
hardware. Use a deep socket to tighten the nut.

2.9 Tubing Connections (Fig. 7)
a. The standard tubing connections on the Pure Water Machine are of “JACO” design
and manufacture. Use the tubing sections provided and the tubing inserts. Follow
the instructions in Figure 7 to make the connections. Use a 5/8” open-end wrench
to tighten the JACO nuts on the tube. Hand tightening is not sufcient and may lead
to leaks. MAKE SURE THAT THERE ARE NO THREADS SHOWING UNDER
THE NUT. If you cut the tubing, make sure it is square cut so the tubing insert ts
squarely against the end.

b. Feed Water Line
Connect the orange colored 1/4” inlet tubing to the ball valve installed in step 2.4
above. To reduce the Water-Hammer effect on this tting, make a large loop in the
tubing before the connection on the sediment lter. To connect, remove compression
nut and ferrule and slide on to tube. Insert tube over the ball valve tube as shown in
Fig. 3. Slide nut over threads and tighten.
c. Drain Line
Find the black colored 1/4” tubing. Connect the tube to the drain saddle clamp from
step 2.5. Push tube into tting about 1/2 inch. Tighten plastic nut.
d. Faucet Line
Find the white colored 1/4” tubing and install a tube insert into the end of the tube.
Slide on the ferrule and compression nut. Connect the tube to the faucet. Push the
tube into the tting until it stops. Tighten the metal ferrule nut.
e. Tank Line
Install the plastic ball valve on the storage tank. Find the yellow colored 1/4” tubing
and install a tube insert into the end of the tube. Connect the tube to the plastic ball
valve on the tank. Push tube into tting until it stops. Tighten plastic nut. Turn the
valve to the on position. The tank comes pre-charged from the factory at 5-7 psi.
Double check the pressure with a tire gage (the air tting is on the opposite end
of the tank from the ball valve). If it is less than 5 psi add 2 psi with a compressor
or bicycle pump. Note: Putting more pressure than 7 psi does not help to increase
water ow through the faucet.

2.10 Air-Gap Faucet Installation (Figure 8)
Air-Gap Faucets are sometimes required by municipal code. The faucet is designed
to take the waste water from the membrane to the top of the sink and then let it ow
by gravity to the drain saddle. The objective is to prevent possible backup of drain
water from the sink to the membrane in the event of a sink clog. A drain saddle with
3/8” instead of 1/4” is used. An extra section of 3/8” tubing (blue) is used from the
faucet to the drain.
Sink Preparation
Drill the appropriate size hole in the kitchen sink to accommodate the air-gap faucet.
Drain Connection
Follow instructions of section 2.5 except drill a 3/8” hole in the drain pipe.
Tubing Connections
Find the black colored 1/4” drain line from the membrane. Remove from membrane
housing. Connect this tube to the 1/4” barbed tting on the air-gap faucet.
Find the 3/8” blue tubing in the parts kit. Connect this tube to the 3/8” barbed tting on
the air-gap faucet. Install the faucet assembly (with tubes attached) into the sink hole.
Secure the faucet per instructions in section 2.8. Re-attach the 1/4” black tubing to the
drain side of the RO membrane housing. Be sure to tighten the tting nut securely.
Attach the 3/8” tube to the drain connector. Tighten the tting nut securely. Attach the
pure water line to the faucet per the instructions in section 2.9-D.
Note: To reduce drain noise gently curve the black tubing from the air-gap faucet to
the drain connection.

3.0 System Start-Up
3.1 Start-Up
Start the system by opening the feed water ball valve. Make sure the ball valve on
the storage tank is in the closed position. Check for leaks for at least 10 minutes. If
water leaks from a tting, retighten the tting nut. Open the product water faucet
and let the water ow until all the air has been expelled from the system. This will
take about 30 minutes. Close the product water faucet. Make sure drain water has
stopped owing within one minute.
Open the tank ball valve and let the system run about 2-hours to get a complete
tankful. Then open the clean water faucet on the sink and empty the tank. This is
to ush the system and remove the preservative from the RO membrane, as well as
ush carbon “nes” from the post lter
If the waste water continues to run after the tank is full, it may mean there is air
binding the autovalve. Empty the tank again by opening the faucet. This will help
to clear more air from the system. If the waste water running persists, remove the
connection and the stainless steel checkvalve at the outlet of the RO stage. Clean the
check valve, reassemble and start the system again.
3.2 Air Purge
The water moves slowly through the PureWaterMachine™. Small amounts of air
therefore tend to hang up in corners and accumulate over a period of time. This
can cause the autovalve to malfunction (not close properly), letting water run
continuously to the drain. The instructions in 3.1 “Start-Up” should be rigidly
followed.
4.0 Recommended Filter Changes
4.1 Filter Replacement, Pure Water Machine

5.0 Filter Replacement Procedure
Turn off the feed water at the feed water ball valve. Empty at least 1.5 gallons from
the storage tank to take any back pressure off the system. Put a shallow pan under
the RO system to catch any water that may spill during the operation.
Unscrew the lter housing and carefully lift it to the sink to drain or empty the water
remaining in it. Remove the spent lter cartridge. Remove the old “O” rings in the
housing. Sanitize the housings by adding 1 tablespoon of chlorine bleach to the
empty housing and then lling with tap water. Let stand for 10 minutes. Empty the
solution and rinse with clear water and dry.
Install the new cartridges in the housings. Make sure the white polypropylene
sediment element goes into the housing marked “sediment” and the carbon lter
goes into the housing marked “carbon”. Prepare the new “O” rings by covering with
a thin layer of Vaseline or cooking oil. Install the new “O” rings into the grooves
of the housing. Screw the housing to the cap on the bracket. When the “sediment”
and “carbon” labels on the housing are centered at the front, the housings should be
secure (See Figure 9).

– 12 –
If there is a small leak when the water is turned on, a slight turn of the housing
(about 1/4”) should stop it. DO NOT OVER TIGHTEN. If the leak persists, unscrew
the housing and re-seat the “O” ring into the groove
For the in-line post lter, loosen both compression ttings and remove tubing as well
as complete tting. Remove in-line lter and discard. Install new lter. Reinstall
the compression ttings making sure to use teon tape on the threaded portion of
the tting that goes into the lter. Reinstall the tubing at each end and tighten the
compression nuts. Re-start the system by opening the feed water ball valve. Follow
the procedure in 3.1.
5.1 Filter Housing Replacement
The lter canisters, sediment and carbon, including the caps must be replaced every
ve years. Order Vertex part number FH-1000 to order replacement part.

This system has been tested for the treatment of water containing pentavalent arsenic (also know as As(V), As(+5), or arsenate) at
concentrations of [0.050 mg/L or 0.30 mg/L] or less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic.
This system is to be used on water supplies containing a detectable free chlorine residual or on water supplies that have been demonstrated
to contain only pentavalent arsenic. Treatment with chloramines (combined chlorine) is not sufficient to ensure complete conversion of
trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the Performance Data Sheet for further information.
Conforms to NSF/ANSI 58 for pentavalent arsenic reduction. See 8.2arsenic facts section for an explanation of reduction performance.
This system contains replaceable treatment components critical to effective reduction of TDS. Replacement parts and numbers are shown below. The
product water should be tested periodically to verify that the system is performing satisfactorily in addition to making the parts replacement specified.

8.2 Arsenic Facts
Arsenic (abbreviated As) is found naturally in some well water. Arsenic in water
has no color, taste, or odor. It must be measured by a laboratory test. Public water
utilities must have their water tested for arsenic. You can get the results from
your water utility. If you have your own well, you can have the water tested. The
local health department or state environmental health agency can provide a list of
certied labs. The cost is typically $15 to $30. Information about arsenic in water
can be found on the internet at the U.S. Environmental Protection Agency website:
www.epa.gov/safewater/arsenic.html.
There are two forms of arsenic: pentavalent arsenic (also called As(V), As(+5),
and arsenate) and trivalent arsenic (also called AS(III), As(+3), and arsenite). In
well water, arsenic may be pentavalent, trivalent, or a combination of both. Special
sampling procedures are needed for a lab to determine what type and how much of
each type of arsenic is in the water. Check with the labs in your area to see if they
can provide this type of service.
Reverse osmosis (RO) water treatment systems do not remove trivalent arsenic from
water very well. RO systems are very effective at removing pentavalent arsenic. A
free chlorine residual will rapidly convert trivalent arsenic to pentavalent arsenic.
Other water treatment chemicals such as ozone and potassium permanganate will
also change trivalent arsenic to pentavalent arsenic. A combined chlorine residual
(also called chloramine) may not convert all the trivalent arsenic. If you get your
water from a public water utility, contact the utility to nd out if free chlorine or
combined chlorine is used in the water system.
The PT-4.0, PT-4.0/P, PT-504 and PT-504P systems are designed to remove
pentavalent arsenic. They will not convert trivalent arsenic to pentavalent arsenic.
The system was tested in a lab. Under testing conditions, the systems reduced
0.30 mg/L (ppm) pentavalent arsenic to 0.010 mg/L (ppm) (the USEPA standard
for drinking water) or less. The performance of the system may be different at
your installation. Have the water tested for arsenic to check whether the system is
working properly.
The RO component in these systems must be replaced every 12 months or when
the test above rises above 10ppm to ensure the system will continue to remove
pentavalent arsenic. The component identication and locations where you can
purchase the component are listed in the installation/operation manual.
9.0 Other Models
9.1 PT-4.0/P and PT-4.0/5/P Pure Water Machine with booster pump
The booster pump is used when the city water pressure is below 40 psi. The booster pump
allows the RO system to run at peak efciency by providing a pressure of about 80 psi to the
RO membrane. (See Fig. 10)
