Equipment Setup
GENERAL
When placing the unit into service, pay attention to the
following guidelines:
ELECTRICAL
Ensure that the line voltage corresponds to the stated
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
toexceed104°F(40°C).
The UFC-420 and UFC-440 systems use the following
connections (Figure 1):
INSTALLATION
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
not to get the pipe sealant inside the pipe when making
the connections.
Do not over tighten the connections. It is recommend-
ed 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 overtight-
ening.
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:
chlorine bleach
seal tape
UFC-420/440 WATER FILTRATION SYSTEM

A.J. Antunes & Co.
CAUTION
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).
CAUTION
Waterpressuremustnotexceedamembranedif-
ferencial pressure of 3 bar (45 psi). To reduce
water pressure, install a water pressure regulator
and set water pressure to 45 psi.
INSTALLATION (continued)
Locating and Mounting the system
Consider these points before mounting the system:
an appropriate electrical outlet when choosing a
mounting location.
programmer controls.
equipment, or items that may be damaged if they
get wet.
future service access.
mounting hardware.
the system when choosing mounting hardware.
mounted to, wall reinforcement may be necessary.
INLET WATER PLUMBING
It is recommended that the inlet water plumbing line
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
the inlet of the filter system, hold a bucket or other con-
tainer 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)
be installed in the water line after the permeate connec-
tion. This will help 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 pres-
sure, inlet pipe size, and system selected. It is recom-
mended 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
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 3). 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.

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
Fi). The time setting for Fi will
be displayed and the decimal point will flash in one
second intervals.
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 sec-
onds, 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. 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 maxi-
mum flow rate.
7. Close the tap and let the system stand with no
water flow for 15 minutes to allow any trapped air
to come out of the hollow fibers. Check for leaks
at all fittings.
CAUTION
Ingesting the protective solution may cause irrita-
tion of the gastrointestinal tract, colic, diarrhea, or
other similar symptoms
INSTALLATION (continued)
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 instal-
lation process. Chlorine bleach can be used to sanitize
the plumbing. The amount of bleach to use depends
on the system installed and the amount of plumbing
downstream of the filter system. Generally, 1 or 2
ounces (30 ml) of bleach will be sufficient to sanitize the
system.
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 filter sys-
tem.
3. Close the inlet water valve and allow the system
to depressurize.
4. 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.
5. When the water flow out of the strainer stops,
not to spill bleach onto clothing or skin. You may
want to add the bleach using a cup. Reattach the
cap on the strainer.
6. Slowly open the inlet water valve and allow water
to flow out of the tap until the smell of bleach is
present.
7. Close the tap and let the system stand with no
water flow for at least 15 minutes to allow the
bleach to sanitize the pipes.
8. After 15 minutes without 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.
9. Close the tap. The sanitization is complete.
Program the timer following the procedure outlined in
the Operation section of this manual.

quality, occasionally some service is required.
Checking the Timer Program
FI) and the deci-
mal 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 that cre-
ates 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.
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.
the top and bottom end caps. DO NOT remove
the top and bottom End Caps yet.

tridge, being careful to retain the O-rings from
each cap. Set the O-rings aside.
9. Install a new cartridge to the system.
10. Connect the permeate port connection.
11. 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.
12. 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.
13. 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.
SYSTEM SANITIZATION
Over time and use, the plumbing downstream from the
