Protect from becoming dry
If the membrane dries out, irreversible dam-
age to the Ultra Filter membrane may result.
Protect the lter from becoming dry by
keeping it wet and sealed at all times.
Protect from freezing
If the Ultra Filter 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 Ultra Filter should
be stored in a dark location.
Protect from high temperatures or
abrupt variation in temperature
The maximum operating temperature is
104°F (40°C). Avoid abrupt variations in tem-
perature. Any temperature variation should
be made slowly.
Protect from rough handling or dropping
Mechanical damage, external breakage,
and/or internal breakage of the lter can
result if the system is dropped or bumped.
Handle with care at all times during trans-
portation and installation.
Protect from organic solvents and con-
centrated acids
Prevent any and all contact of the mem-
brane with strong solvents, solvents
containing chlorine, or concentrated acids.
Do NOT use strong solvents or concen-
trated acids on any plastic parts of the
lter system. Examples of some solvents to
avoid: acetone, methyl acetate (nail polish
remover); hexane (spot removers); turpen-
tine, 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 ushed
clean before installing the lter. All plastic
parts of the lter 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.

P/N 1011180 Rev. C 11/16 7
OVERVIEW
The UFL system operates in two modes:
yNormal Operation Mode
yFlush Mode
During Normal Operation Mode, water
enters the Inlet and ows through the Ultra
Filter before exiting the Permeate Outlet as
usable product water.
During Flush Mode, the Drain Valve opens
and water entering the Inlet ushes and
cleans the Ultra Filter membrane by remov-
ing any debris collecting on the membrane
wall.
The Drain Valve is only powered during
Flush Mode.
NOTE: Do NOT unplug the power cord or
turn o the system during Flush
Mode. If there is a power out-
age or the system is unplugged,
water will continue to be ltered
but the system will NOT ush.
This could cause the Ultra Filter
to plug prematurely and may
reduce the life of the lter.
The ush is automated by the controller
to last 10 seconds and take place in one
hour intervals. This interval can be changed
(see Changing the Interval Setting in the
Maintenance section of this manual.
CAUTION
Changing the ush interval may cause
the Ultra Filter to plug prematurely and
may reduce the life of the lter. Consult
the factory for more information.
Manual Flushing
A manual ush can be activated at any
time by pressing the FLUSH button on the
Universal Pulse Controller.
When the FLUSH button is pressed, the
Flush LED on the controller ashes and the
Drain Valve opens for 10 seconds. After
ushing is complete, the Drain Valve will
close, the Flush LED will stop ashing, and
the unit automatically returns to Normal
Operation Mode.
NOTE: A Manual Flush will not aect the
interval ush setting.

Equipment Setup
General
When placing the system into service, pay
attention to the following guidelines:
yDo NOT immerse cord or plug in
water.
yKeep cord away from heated surfaces.
Electrical
The line voltage must match the voltage
on the specication label. The plug on the
power cord must match the appropriate
outlet. Do NOT connect the system to a
switched electrical outlet.
Plumbing
NOTE: The system must be connected to
the COLD water line. Do NOT con-
nect the system to the hot water
line.
This system uses the following connections:
Connection Description
System Inlet 1” NPT
Permeate
(Product Water) 1” NPT
Drain 3/4” FNPT
When making a plumbing connection to
the system, use a back-up wrench on the
supporting plumbing. Always use a quality,
approved pipe sealant or thread seal tape
on pipe threads. Do NOT allow pipe sealant
inside pipes.
Do NOT over tighten the connections. Use
plastic ttings when connecting to the
plastic connections of the system.
Mounting the System
The system comes with a pre-attached
Mounting Bracket. When mounting the
system, pay attention to the following
guidelines:
yAllow sucient access for cartridge
replacement. The UFL-410 should be
mounted with 12 inches to the top or
bottom.
yMount the system near but NOT
above an appropriate electrical
outlet.
yMount the system near a drain for
ushing operations.
yMount the system before all
consumable water ltration
processes.
Inlet Water Plumbing
The Inlet water plumbing line should be 1”
NPT or larger. A shuto 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.
An optional “T” or Cross Fitting with cap
or plug can be installed between the Inlet
Valve and the System Inlet. This tting can
be used for draining and sanitizing the
system and downstream plumbing.
The system should only be connected to the
cold water line.
Before connecting the tting to the System
Inlet, the plumbing to the system must be
ushed clear of all debris. Hold a bucket
at the inlet water line and slowly open the
Inlet Water Valve. Allow the pipe to ush
until all debris is removed.

Suggested Tools and Supplies for
Installation
The following tools and supplies are sug-
gested to help with the installation:
yScrewdriver
yAdjustable Wrenches
yDrill with Bits
yLevel
yTape Measure
yPipe Dope or Thread Seal Tape
yTwo Gallon Bucket
yFresh, Unscented Liquid Chlorine
Bleach
yPipe Wrenches
yGarden Hose (for rinsing)
yHose or pipe for drain line
yMount the system with the provided
Mounting Bracket and hardware

P/N 1011180 Rev. C 11/16 9
Drain Valve Connection
The drain hose is for ushing particle
buildup out of the
system during self cleaning.
1. Cut a length of braided tubing so
it reaches the drain from the Drain
Valve.
2. Connect one end of the hose to
the Drain Valve and secure it with a
Worm Clamp (Figure 4).
3. Direct the other end of the hose to
the drain.
When connecting the drain hose, pay atten-
tion to the following guidelines:
yThe drain line plumbing must be
able support the ow rate whenever
the system ushes. This ow rate
is dependent on the inlet water
pressure, inlet pipe size, and system.
yThe drain line leading out of the
system must be as short as possible
and slope downwards without any
kinks or loops.
yThe drain line plumbing must be
position and secured at least 2
inches above the drain (Figure 4).
This air gap protects the system
from contamination in the event of a
backed-up drain.
yThe drain used must not be blocked
or restricted.
yThe drain used must be as large or
larger than the drain line plumbing.
Permeate Line Plumbing
To ensure the highest quality and safest
water, it is recommended that a check valve
(to prevent back ow) be installed in the wa-
ter line after the permeate connection. This
will help prevent possible contamination
of the lter 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
specication.
A shuto valve (not supplied) should be
installed in the ltered water line lead-
ing from the system. The valve should be
mounted close to the system outlet and
sized properly for the plumbing line. This
valve will allow for easier servicing and
future cartridge replacement.
