UFL-420/440 WATER FILTRATION SYSTEM
OVERVIEW
Overview
The UFL system operates in two modes:
• Normal Operation Mode
• Flush Mode
During Normal Operation Mode, water enters the Inlet
and flows 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 flushes and cleans the Ultra Filter
membrane by removing 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 off
the system during Flush Mode. If there is a power
outage or the system is unplugged, water will continue to be filtered but the system will NOT flush.
This could cause the Ultra Filter to plug prematurely and may reduce the life of the filter.
The flush 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 flush interval can cause the Ultra
Filter to plug prematurely and may reduce the life
of the filter. Consult the factory for more information.
Manual Flushing
A manual flush 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 flashes and the Drain Valve opens for 10
seconds. After flushing is complete, the Drain Valve will
close, the Flush LED will stop flashing and the unit will
automatically return to Normal Operation Mode.
NOTE: A manual flush will not affect the interval
flush setting.

Equipment Setup
GENERAL
When placing the unit into service, pay attention to the
following guidelines:
• Do NOT immerse cord or plug in water.
• Keep cord away from heated surfaces.
SUGGESTED TOOLS AND SUPPLIES FOR INSTALLATION
The following tools and supplies are suggested to make
the installation easier:
• Screwdriver
• Drill with bits
• Tape measure
• Two gallon bucket
• Pipe wrenches
ELECTRICAL
• Adjustable wrenches
• Level
• Pipe dope or thread seal
tape
• Fresh 5 1/4% liquid chlorine
bleach
PLUMBING
NOTE: This unit is designed to use tap water not to
exceed 100°F (38°C) or 100 psig (690 kPa).
The UFL-420 and UFL-440 systems use the following
connections (Figure 1):
• Water Inlet 1” NPT
• Permeate (Product Water) 1” 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 thread seal 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.
IMPORTANT
Commonwealth of Massachusetts Plumbing Code
248 CMR shall be adhered to. The use of saddle

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 connection. 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.
A shutoff valve (not supplied) should be installed in the
filtered water line leading 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.
Drain Valve Connection
The drain hose is for flushing particle buildup out of the
system during self cleaning.
1. Cut a length of the provided 20-foot coil 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 provided Worm Clamp (Figure
4).
3. Direct the other end of the hose to the drain.
When connecting the drain hose, pay attention to the
following guidelines:

• The drain line plumbing must be able support the
flow rate whenever the system flushes. This flow
rate is dependent on the inlet water pressure, inlet
pipe size, and system.
• The drain line leading out of the system must be
as short as possible and slope downwards without
any kinks or loops.
• The 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.
• The drain used must not be blocked or restricted.
• The drain used must be as large or larger than
the drain line plumbing.

INSTALLATION (continued)
Sanitizing the System and Lines
The plumbing must be sanitized to eliminate possible
contamination that may have occurred during the installation process.
One ounce (30 ml) of liquid chlorine bleach (regular
bleach, unscented 5.25 % - 6 % sodium hypochlorite) or Kay-5 sanitizer solution (Sodium Dichloro-sTriazinetrione Dihydrate, 6%) or equivalent can be used
to sanitize the plumbing.
The Kay-5 sanitizer solution is made by dissolving a
1 oz. packet of Kay-5 powder in 2 oz. (60 ml) of clean
warm water. This can be done by removing 1 inch from
the top of the Kay-5 packet and adding the 2 oz. of
warm water to the packet. Mix with a coffee stirrer to
dissolve. When added to the system, this will create a
60-100 ppm chlorine solution.

Resetting the Timer Program
During the normal operation, the system will flush
according to the set interval. It is possible the system
will flush at a time of high water use. If this poses a
problem, the controller can be reset. Unplug the power
supply, wait for 5 seconds, and then plug the power
supply in. When power is restored to the controller, it
will automatically enter Flush Mode. The controller will
then begin timing from the point when power is restored
based on the interval setting selected.
