IMPORTANT SAFETY INFORMATION
• Water pressure must not exceed the membrane
dif ferential pressure of 45 psig (3.1 bar). To
reduce water pressure, install a water pressure
regulator and set system inlet water pressure to
45 psi (3.1 bar).
Protect from becoming dry
If the membrane dries out, irreversible damage to the
membrane may result. Protect the filter from becoming
dry by keeping it wet and sealed at all times.
Protect from freezing
If the membrane freezes during operation or storage,
irreversible damage to the membrane and brittle cracking of the cartridge or housing may result.
Protect from direct sunlight or other UV sources
Avoid long-term exposure to direct sunlight or other UV
sources. The filter should be stored in a dark spot.
Protect from high temperatures or abrupt variation
in temperature
The maximum operating temperature is 100oF (40oC).
Avoid abrupt variations in temperature. Any temperature variation should be made slowly.
Protect from rough handling or dropping
Mechanical damage, external breakage, and/or internal
breakage of the filter can result if the system is dropped
or bumped. Handle with care at all times during transportation and installation.
Protect from organic solvents and concentrated
acids
Prevent any and all contact of the membrane with
strong solvents, solvents containing chlorine, or concentrated acids. Do not use strong solvents or concentrated acids on any plastic parts of the filter system.
Examples of some solvents to avoid: acetone, methyl
acetate (nail polish remover); hexane (spot removers);
turpentine, toluene (paint thinners); dry cleaning solutions, insecticides.
Protect from abrasive material
The membranes must be protected from abrasive
materials like shavings left in a pipe. Abrasive materials
in contact with the membrane can cause irreversible
damage to the membrane. All pipes must be flushed
clean before installing the filter. All plastic parts of the
filter system must be protected from sharp objects like
knives, sand paper or other tools. Cutting or nicking
a plastic part can weaken it and cause a leak. Do not
use abrasive cleansers on any plastic parts.
Protect from water hammer
The system must be protected from shock, pressure
surges, or pulsation that may occur inside water pipes.
Water hammer occurs in pipes when a valve or faucet
shuts quickly. Install a water hammer arrestor (pressure vessel containing compressed air separated from
the water by a diaphragm) to reduce pressure shock.

Unpacking
1. Remove the system and all packing materials
from the shipping carton.
2. Remove all packing materials and protective coverings from the system
3. Remove the information packet. To prevent any
delay in obtaining warranty coverage, fill out and
mail the warranty card.
NOTE: If any parts are damaged, contact Antunes
Filtration Technologies IMMEDIATELY at 1-800-2532991 (in the U.S. only) or 1-630-784-1000.
Equipment Setup
GENERAL
When placing the unit into service, pay attention to the
following guidelines:
• Make sure power to the unit is off.
• Do not immerse cord or plug in water.
• Keep cord away from heated surfaces.
ELECTRICAL
Ensure that the line voltage corresponds to the stated
voltage on the units specification label. Make sure that
the plug on the power cord from the system and the
outlet match. For proper operation, and to ensure the
highest quality water from the system, make sure that
the system is not connected to a switched electrical
outlet.
PLUMBING
NOTE: This unit is designed to use tap water not
to exceed 104°F (40°C).
The UF-420 and UF-440 systems use the following connections (Figure 1):
• Water Inlet 3/4” NPT
• Permeate (Product Water) 3/4” NPT
• Drain 3/4” NPT
When making a plumbing connection to the system,
remember to use a back-up wrench on the supporting
plumbing. Always use a good quality, approved, pipe
sealant or Teflon® tape on pipe threads. Be careful not
to get the pipe sealant inside the pipe when making the
connections.
Do not over-tighten the connections. It is recommended that plastic fittings be used when connecting to the
plastic connections of the system. This will reduce the
possibility of cracking the connections due to overtightening.
If soldered plumbing is used, do not apply heat to, or
near, the filtration system. The use of union (O-ring
seal) connections is highly recommended for ease of
installation and future servicing.
SUGGESTED TOOLS AND SUPPLIES FOR INSTALLATION
The following tools and supplies are suggested to make
the installation easier:
• Screwdriver
• Drill with bits
• Strap wrench
(up to 6” diameter)
• Tape measure
• Two gallon bucket
• Fresh 5 1/4% liq uid chlorine bleach
(such as Clorox®)
This equipment is to be installed to comply with
the basic plumbing code of the Building Officials
and Code Administrators, Inc. (BOCA) and the
Food Service Sanitation Manual of the Food and
Drug Administration (FDA).
Water pressure must not exceed a membrane
burst pressure of 7 bar (100 psi). To reduce water
pressure, install a water pressure regulator and
set water pressure to suit application. Note that
the trans membrane pressure must be .5 - 2.5 bar
(7 - 36 psi).
• Adjustable wrenches
• Pipe wrenches
• Level
• Pipe dope or Teflon®
tape
CAUTION
CAUTION
Locating and Mounting the system
Consider these points before mounting the system:
• Note the location of the water supply, drain, and
an appropriate electrical outlet when choosing a
mounting location.
• Remember to allow for access to the timer/
programmer controls.
• Do not mount the system above any electrical
equipment, or above items that may be damaged if
they get wet.

INSTALLATION (continued)
• Install the system in a location that will allow for
future service access.
• Mount the system on a wall using appropriate
mounting hardware.
• Remember to consider the operating weight of
the system when choosing mounting hardware.
Depending on the type of wall the system is being
mounted to, wall reinforcement may be necessary.
Mount the filtration unit using the Mounting Bracket
(Figure 3) using 1/4” by 1” bolts or bolts of the metric
equivalent.
Figure 3. Mounting Bracket (Front View)
INLET WATER PLUMBING
It is recommended that the inlet water plumbing line
be 3/4” NPT or larger. A shutoff valve (not supplied)
should be installed in the line leading to the system.
The valve should be mounted close to the system inlet
and sized properly for the inlet plumbing line. This
valve will allow for easier servicing and future cartridge
change-out. The system should only be connected to
the cold water line.
To ensure that the highest quality water is produced
from the system, the plumbing leading to the filter
system must be flushed clear of all debris before the
system is hooked up. Before making the connection to
the inlet of the filter system, hold a bucket or other container at the inlet water line and slowly open the inlet
water valved. Allow the pipe to flush until all debris is
removed.
PERMEATE LINE PLUMBING
To ensure the highest quality and safest water, it is
recommended that a check valve (to prevent backflow)
is installed in the water line after the permeate connection. This helps prevent possible contamination of the
filter system due to other equipment downstream. The
check valve (not supplied) should be mounted close to
the system outlet and sized properly for the plumbing
line. Check with local codes for the proper specification.
DRAIN LINE PLUMBING
The drain line is used to flush away the particle buildup
when cleaning the filter. The drain line must be able
to support the flow rate when the system flushes. The
flow rate from the flush depends on the inlet water pressure, inlet pipe size, and system selected. It is recommended that the drain line be as large as, or larger
than, the inlet plumbing line. The drain line should be
as short as possible, sloping downward without kinks
or loops. Be sure that the drain used is not blocked or
restricted.
The filter system must be protected from possible back
contamination by the installation of an air gap between
the drain connection of the system and the drain
(Figure 4). This gap in the line, with no physical contact
between the system and sewer, prevents contamination
of the system in the event of a backed-up sewer.
NOTE: Make sure that the end of the drain line is
positioned and secured at least 2 inches above
the drain so that the water flow is directed into the
drain, without splashing.
FLUSHING AND STARTING THE SYSTEM
To ensure that the highest quality water is produced
from the system, the plumbing leading from the filter
system must be flushed clear of all debris after the
system is hooked up. After making the connection
to the outlet of the filter system, open a faucet or tap
closest to the filter system, then slowly open the inlet
water valve. Allow the pipe to flush until all debris is
removed.
The unit also must be flushed to remove air and the
shipping/storage solution. For maximum quality, the
permeate water produced during the flushing procedure
must be discarded. Direct this permeate water to drain.

1. Plug the power cord into the appropriate electrical
outlet. The unit will power up and the LED display
will display the following for about two seconds
each:
• 8.8
• F8 followed by its time settings in seconds
• Fi and its time setting in minutes or hours.
The F8 and Fi sequence repeats for 30 seconds
after which the unit automatically returns to the
Flush Interval Mode (Fi). The time setting for Fi will
be displayed and the decimal point will flash in one
second intervals.
CAUTION
Ingesting the protective solution may cause irritation of the gastrointestinal tract, colic, diarrhea, or
other similar symptoms
2. Open the tap or faucet closest downstream to the
filter system.
3. Slowly open the inlet water valve and allow water
to enter the system.
4. Press and hold the Start button. After 6-7 seconds, the drain valve will open and FL will appear
on the display.
5. Continue holding the Start button down for at least
30 seconds to keep the drain open. This flushes
air out of the center of the hollow fibers of the cartridge filter. The drain will remain open as long as
the Start button is pressed. Check to make sure
that the drain water is directed into the drain without splashing.
6. Release the Start button. This closes the drain
valve. Water should continue to flow through the
system and out of the open tap. Allow water to
flow out of the tap for at least 15 minutes at maximum flow rate.
7. Close the tap and let the system stand without
water flow for 15 minutes to allow any trapped air
to come out of the hollow fibers. Check for leaks
at all fittings.
8. After 15 minutes without water flow, open the
tap for 5 minutes to allow any trapped air to be
flushed out.
9. Close the tap. Flushing is complete.
SANITIZING THE SYSTEM AND LINES
The plumbing must be sanitized to eliminate possible
contamination that may have occurred during the installation process. Chlorine bleach can be used to sanitize
the plumbing. The amount of bleach used depends
on the size of the system installed and the amount of
plumbing downstream of the filter system. Generally,
one ounce (30 ml) of bleach will be sufficient to sanitize
the system.
1. Make sure that the system has been flushed of
air and debris as described in the Flushing and
Starting up the System section of this manual.
2. Open the tap closest downstream to the filtration
system and close the inlet water valve and allow
the system to depressurize.
3. Place a bucket under the strainer at the inlet
connection to the system. Open the strainer by
unscrewing the cap. Water will flow out of the
strainer as the system drains.
4. When the water flow from the strainer stops, pour
the liquid bleach into the strainer. Be careful not
to spill bleach onto clothing or skin. Re-attach the
cap on the strainer.
5. Slowly open the inlet water valve and allow water
to flow out of the tap until the smell of bleach is
present.
6. Close the tap and let the system stand without
water flow for at least 15 minutes to allow the
bleach to sanitize the pipes.
7. After 15 minutes without water flow, open the tap
and flush until the presence of bleach is gone. All
other taps should be opened to flush any bleach
from the plumbing.
8. Close the tap. The sanitization is complete.

Filtration Process
Water filtration in the UF Series is accomplished using
two modes:
• Flush Interval (Fi on the LED display)
• Flush Duration (Fd on LED display).
During the Flush Interval mode, water enters the inlet
and flows through the filter element before exiting the
Permeate outlet as usable product water. After a certain period of time, depending upon water quality, the
filter has to be cleaned. This is accomplished through
the Flush Duration Mode. During this mode, the drain
valve opens and flushes the membrane to remove
debris collected inside the membrane walls.

Checking the Timer Program
During normal operation, the system displays the time
setting for the Flush Interval Mode (FI) and the decimal will flash in one second intervals. This is the time
between flushing, not a time of day setting.
Over time, it is possible that the time that the system
flushes occurs at a time of high water use. If this creates a problem, the timer can be reset by unplugging
the power cord, waiting for 5 seconds, and plugging the
power cord in again. The timer then begins timing from
the point power is restored to the system. Follow the
procedures within the Operation section of this manual
to check and set the timer settings.
Changing the Cartridges
While the filtration system is designed for long life,
eventually the cartridges will need to be replaced.
1. Open the faucet or tap closest downstream to the
filtration system.
8. Using a screwdriver, remove the screws from the
cartridge bracket and set the bracket and screws
aside.
9. Unscrew the cartridge end caps from the cartridge, being careful to retain the O-rings from
each cap. Set the O-rings aside.
10. Install a new cartridge to the system using the
cartridge bracket and screws saved from Step 8.
11. Connect the permeate port connection.
12. Inspect the O-rings to make sure they are clean
and are not splitting or cut. For all O-rings, make
sure they are lubricated with an approved food
grade lubricant acceptable for drinking water use.
13. For each end cap, position the O-ring between the
end of the cartridge and cap and screw the cap
onto the cartridge. Tighten with strap wrench as
necessary.
14. Follow the Flushing and Starting the System and
Sanitizing the System and Lines procedures in the
Installation section of this manual to complete the
cartridge change.
2. Close the inlet water valve and allow the system
to depressurize.
3. Place a bucket under the strainer at the inlet
connection to the system. Open the strainer by
unscrewing the cap. Water will flow out of the
strainer as the system drains.
4. Press and hold the Start button to help drain the
system.
5. Reattach the cap on the strainer when the water
flow stops. Unplug the power cord.
Figure 14. Manual Flush
6. Using a strap wrench (up to 6” capacity), loosen
the top and bottom end caps. DO NOT remove
the top and bottom End Caps yet.
System sanitization
Over time and use, the plumbing downstream from the
system may require sanitization. It is recommended
that the system and downstream plumbing be sanitized at least once a year. When necessary, follow the
Sanitizing the System and Lines procedure in the
Installation section of this manual.
7. Disconnect the permeate port connection.
