13 ROM IV REVERSE OSMOSIS SYSTEM INSTALLATION AND OPERATION GUIDE
HOW REVERSE OSMOSIS (RO) WORKS
The ROM IV RO System uses a semi-permeable membrane to
reduce dissolved salts, improving the taste and odor of your
water. The RO membrane cartridge contains multiple layers
of micron-thin film wound around a hollow center core. Water
molecules can pass through the cartridge, while dissolved
salts are rejected.
Your water supply is prefiltered to reduce dirt and chlorine
that may foul the membrane. The RO membrane cartridge
separates this prefiltered water into PRODUCT WATER and
REJECT WATER. Water pressure forces water through the
membrane within the RO membrane cartridge, and into
the storage tank. This is the product water. Dissolved salts
cannot pass through the membrane and are sent to the
drain as reject water. When the faucet is opened, product
water (permeate) is drawn from the storage tank through a
post-polishing filter. The post-polishing filter takes out any
remaining taste or odor in the water and provides you and
your family with cleaner, great-tasting water.
The ROM IV RO System also features an auto shut-off valve
which shuts off the system once the pressure in the storage
tank reaches 2/3 of the incoming water pressure (your water
pressure). When you open the faucet to draw water from the
storage tank, the pressure inside the tank drops and the auto
shut-off valve opens. The system then begins to operate,
replenishing the water you took from the storage tank.
Depending on the system's efficiency, for each gallon of water
produced, up to 1 gal (3.79 L) is discharged as reject water.
The storage tank can hold up to 3.2 gals (12.1 L) of water at a
time.
NOTE: When used under operating conditions specified
in this manual, the RO membrane cartridge of the
ROM IV RO System should last 12 to 24 months. The
precise life span of the RO membrane cartridge
will depend on the quality of the water entering
the system and the frequency with which you use
it. Frequent use prevents the dissolved salts from
building up on the membrane as scale. The more
water the system is required to produce, the longer
the membrane will last.
INSTALLATION
NOTE: Please read all instructions, specifications, and
precautions before installing and using your
ROM IV RO System.
NOTE: The ROM IV RO System may be installed under a sink,
counter or water cooler.
NOTE: The ROM IV RO System is installed vertically.
NOTE: Numbered diagrams correspond with
numbered steps.
Selecting the Faucet Location
NOTE: The drinking water faucet should be positioned with
function, convenience, and appearance in mind. An
adequate flat area is required to allow faucet base to
rest securely. The faucet fits through a 1-3/8" hole.
Most sinks have pre-drilled 1-3/8" or 1-1⁄2" diameter
holes that may be used for faucet installation. If
these pre-drilled holes cannot be used or are in an
inconvenient location, it will be necessary to drill a
1-3/8" hole. This procedure may generate dust which
can cause severe irritation if inhaled or come in
contact with the eyes. The use of safety glasses and
respirator for this procedure is recommended.
WARNING: Do not attempt to drill through an
all-porcelain sink. If you have an all-porcelain
sink, mount the faucet in pre-drilled sprayer
hole or drill through countertop next to sink.
WARNING: When drilling through a countertop, make sure
the area below the drilled area is free of wiring
and piping. Make certain that you have ample
room to make the proper connections to the
bottom of the faucet.
WARNING: Do not drill through a countertop that is more
than 1-inch thick.
WARNING: Do not attempt to drill through a tiled, marble,
granite or similar countertop. Consult a plumber
or the countertop manufacturer for advice or
assistance.
1. Line bottom of sink with newspaper to help prevent
metal shavings, parts, or tools from falling down drain.
2. Place masking tape over the area to be drilled to help
prevent scratches if drill bit slips.
3. Mark hole with center punch. Use a 1/4" drill bit for a
pilot hole.
4. Using a 1-3/8" hole saw, drill a hole completely through
the sink. Smooth the rough edges with a file.

Connecting the Faucet
CAUTION: Water supply to the inlet of the ROM IV RO System
should have a separate shut-off valve. If it does
not, a separate shut-off should be installed.
1. Locate the 3/8" blue tubing from the faucet. See Figure
5. The tubing must not have sharp bends or kinks that
would restrict water flow. Cut length as needed. Place a
mark 3/4" (1.9 cm) from the end of the tubing.
IMPORTANT: A length of this 3/8" blue tubing will be
used to connect the storage tank to the manifold. When
cutting this tube, plan for the new piece to be used for
the tank.
Moisten the end of the tubing with water and insert
into the water outlet quick-connect fitting on the head
assembly . Push in until the mark is flush with the
quick-connect fitting.
2. Gently pull back on the tubing to ensure it is connected
properly. If the tubing comes out of fitting, cut a small
section off of the tubing and reconnect.
NOTE: Tubing may be quickly and easily removed from the
fitting if necessary. First, turn off the water supply to
the filter. Open faucet, then press in the collet around
the fitting while pulling the tubing with your other hand.

side) head until the 3/4" mark is flush with the quick-
connect fitting.
NOTE: The pressurized storage tank has capacity of 3.2 gals
(12.1 L). The tank's air pressure is factory-set at 5 to
7 psi when tank is empty.
PUTTING THE SYSTEM INTO OPERATION
CAUTION: Make certain head assembly is firmly attached
to wall to prevent it from falling and possibly
becoming damaged.
NOTE: The ROM IV RO System does not produce a high
volume of water on-demand as an ordinary filter
does. Water is produced at a slow, drop-by-drop rate.
The system requires about three (3) hours to fill the
storage tank. As water is taken from the tank, the
system automatically starts the cycle of replacing the
water and then stops water production when the tank
is full.
There are several steps that must be followed to properly
place the ROM IV RO System into operation. Before the supply
water is turned ON, see Figure 13:
Remove quick-connect plug on the left end of the
manifold and connect the port with tubing to a drain.
Turn shut-off valve to the OFF position.
Turn tank valve to the OFF position.
The faucet lever should be closed.

insert a temporary length of tubing into the connection.
NOTE: Tubing and ball valve are supplied.
Turn on the incoming water supply. Flush the ROM-PRE
Cartridge to a drain for five (5) minutes at full flow to
remove any carbon fines.
CAUTION: Failure to flush the ROM-PRE Cartridge will
damage the ROM-G75 RO Membrane Cartridge.
This condition will void the warranty.
2. After five (5) minutes, close the incoming water valve.
Remove the temporary tubing and re-insert the quick-
connect plug.

3. Make sure tank valve is in the open position.
4. Open the shut-off valve.
5. Slowly turn on incoming water supply.
6. Open the faucet to turn on flow. Let the faucet run/drip
for 12 hours, then close it.
7. Allow three (3) hours for the tank to fill. Continue to
periodically check the installation for leaks. After
the storage tank is filled, open the faucet to flush the
postfilter cartridge (on the right side of the filter housing
assembly). Allow four (4) to five (5) minutes for all of the
water to drain from the tank. Close faucet and allow tank
to fill.
8. Repeat Step 7 three (3) times.
CAUTION: Visually check the entire system for leaks. If a
leak is present, see Troubleshooting.
NOTE: Initially, the water may appear cloudy. This is a result
of air trapped in the postfilter cartridge. It is not
harmful and will disappear in a matter of minutes. It
may take up to a week after installing a new
postfilter cartridge for the trapped air to dissipate.
The system is ready for operation. You can now enjoy quality
water from the ROM IV RO System.
TESTING YOUR REVERSE OSMOSIS SYSTEM
Total Dissolved Solids (TDS) Test
NOTE: Under NSF/ANSI Standard 58, it is highly
recommended that the product water is tested at
least every six (6) months to verify that the system is
performing satisfactorily.
WHEN TO CHANGE THE CARTRIDGES
The life of the cartridge depends on the water volume used
and the substances in the water. Normally, cartridges should
be changed at intervals of 12 months. Replace the cartridge
sooner if the water pressure at the faucet begins to drop
noticeably or if you notice changes in the taste, color, or flow
of the filtered water.
CHANGING THE CARTRIDGES
Replacement Cartridges:
Everpure ROM-PRE Filter Cartridge - EV929675
Everpure ROM-PST Filter Cartridge - EV929676
Everpure ROM-G75 RO Cartridge - EV929775
The prefilter and postfilter cartridges need to be changed
when the water pressure at the faucet begins to drop
noticeably or if there are changes in taste, color or flow of
the filtered water. All cartridges should be changed at the
same time. The cartridges are color-coded to indicate which
location they are installed into.
NOTE: Only the replacement cartridges listed can be used
with this system. Failure to use the recommended
replacement cartridges will void your warranty.
1. Place a small pan or towel under the ROM IV RO System
to catch any water tha may drip. Turn OFF incoming
water.
2. Remove the two (2) outside cartridges by twisting each
cartridge a 1/4-turn to the left (counterclockwise). Then
pull down to release.
3. Remove the center ROM-G75 Cartridge by swinging the
cartridge up and out, pivoting at the top connection. Once
the cartridge is out of the clips, the quick-connection at
the top can be disconnected. Disconnect both tubes from
the quick-connect fittings at the bottom.
4. Connect the red and blue tubes at the bottom of the new
ROM-G75 Cartridge.
5. Position the new ROM-G75 Cartridge so the inlet port
is in position in front of the tubing at the top of the
cartridge. Push the cartridge onto the tubing until it
reaches full depth. Swing the cartridge down (the elbow
fitting must swing with it) into the clips. Adjust the
cartridge up or down so the tubing and the elbow point
directly into the cartridge.
NOTE: The bottom of the ROM-G75 Cartridge will be
supported by the lower leg of the bracket.
6. Position the ROM-PRE Cartridge under the left side
head. Line up the tabs on the cartridge with the slots in
the head.
7. Push the new cartridge into the head until it can go no
further.
8. Twist the cartridge a 1/4-turn to the right (clockwise)
until it locks in place. Pull gently down to ensure the
cartridge is locked in place.
9. Repeat Steps 6, 7 and 8 for the ROM-PST Cartridge.
CAUTION: The ROM-PRE Cartridge may contain carbon fines
that will be removed during the initial flushing.
Follow the proper flushing procedure to prevent
damage to the ROM-G75 RO Cartridge.
20 ROM IV REVERSE OSMOSIS SYSTEM INSTALLATION AND OPERATION GUIDE
INITIAL FLUSHING OF CARTRIDGES
The installation of new cartridges requires that a preliminary
flushing of the cartridges be performed. This initial flushing
is required to prevent damage to the RO cartridge.
Refer to page 18, Putting the System into Operation, for the
complete flushing procedure.
SANITIZING PROCEDURE  CONTAMINATED WATER
SUPPLY/BOIL ALERTS
When the water system has been contaminated or a boil
water advisory has been discontinued, the ROM IV RO System
must be sanitized. If a boil water advisory has just been
discontinued: Flush the water lines according to your water
supplier's instructions. Open the delivery faucet and flush the
system for about 10 minutes, then follow the filter cartridge
replacement instructions below.
1. Turn off the water supply and open the faucet to
relieve pressure.
2. Remove the filter cartridges and discard in trash. Wash
hands with soap and warm water.
NOTE: If a drip pan is used, clean with dish soap and
warm water.
NOTE: The following steps require placing bleach into
the ROM IV RO System. Pentair Everpure offers a
hollow cartridge, Everpure 2JT Flushing/Sanitizing
Cartridge (EV9608-10), that is designed for this
application. The following steps describe how to use
the Pentair Everpure 2JT Cartridge (EV9608-10).
Sanitization Procedure With The Pentair
Everpure 2JT Cartridge (EV9608-10)
3. Grasp the tip of the outlet tower center, top of the
cartridge and pull out gently. The entire central plug with
the long tube attached will come out, leaving a hole.
Figure 14
4. Add about a teaspoon of laundry bleach (5.25% sodium
hypochlorite solution) to the empty flushing cartridge
through the hole in the top.
5. Lubricate o-ring with a high quality silicone lubricant.
Replace the central plug assembly and insert the
flushing cartridge into the first (left side) installed head.
NOTE: Do not use petroleum jelly to lubricate the o-rings. It
will degrade the o-rings.
CAUTION: DO NOT install the ROM-G75 RO Membrane
Cartridge for the sanitization procedure. The
solution will severely damage the membrane.
Figure 15
6. Install a port plug into the last (right side) head.
7. When the RO cartridge is removed, the blue tube from
the bottom of the cartridge can be used for the sanitizing
procedure. Remove the quick-connect elbow on the blue
tube and remove the short tube at the top
quick-connect elbow.
8. Connect the bottom end of the blue tubing to the quick-
connect elbow that is normally connected to the inlet
port of the RO cartridge.
9. The tank valve and the manifold shut-off valve should be
open. The faucet should be OFF.
10. Slowly open the water supply valve. Open the faucet and
monitor the water flowing out of the ROM IV RO System.
When the smell of chlorine is present, close the faucet
valve. The storage tank will fill with chlorinated water.
11. Wait for a period of at least 30 minutes to allow adequate
disinfection time.
12. Turn off the incoming water valve.
13. Open the faucet valve. The storage tank will drain out.
14. When the storage tank is emptied, close the faucet valve
and remove the 2JT Cartridge.
15. Install a new ROM-PRE Cartridge in the first (left
side) head.
16. Open the faucet valve and slowly open the incoming
water valve. Allow water to run for five (5) minutes. This
will flush carbon fines out of the new cartridge.
17. Close the faucet allowing the tank to fill three (3) to five
(5) minutes.
18. Turn off the incoming water valve.
19. Open the faucet to allow the tank to empty.
20. When the water flow has stopped, close the faucet and
open the incoming water valve to refill the tank for three
(3) to five (5) minutes.
21. Repeat Steps 17, 18 and 19 four (4) times.
22. Turn off the incoming water valve and open the faucet to
