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-216 uses the following connections (Figure 1):
• Water Inlet 1/2” NPT
• Permeate (Product Water) 1/2” NPT
• Drain 1/2” 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.
INSTALLATION
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:
• Screwdriver
• Drill with bits
• Strap wrench
(up to 6” diameter)
• Tape measure
• Two gallon bucket
• Fresh 5 1/4% liquid
chlorine bleach
(such as Clorox®)
• Adjustable wrenches
• Pipe wrenches
• Level
• Pipe dope or Teflon
tape
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
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
trans membrane pressure must be .5 - 2.5 bar (7
- 36 psi).

INSTALLATION (continued)
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 items that may be damaged if they
get wet.
• 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.
INLET WATER PLUMBING
It is recommended that the inlet water plumbing line
be 1/2”” 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.
NOTE: 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 sys-
tem must be flushed clear of all debris before the sys-
tem is hooked up. Before making the connection to the
inlet of the filter system, hold a bucket or other contain-
er at the inlet water line and slowly open the inlet water
valve. Allow the pipe to flush until all debris is removed.
PERMEATE LINE PLUMBING
To ensure the highest quality and safest water, it is rec-
ommended that a check valve (to prevent back flow) 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
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 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
FLUSH THE PIPES
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 clos-
est to the filter system, then slowly open the inlet water
valve. Allow the pipe to flush until all debris is removed.
FLUSH THE MEMBRANE CARTRIDGE
The ultrafiltration membrane cartridge 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 the drain.
1. Plug the power cord into the appropriate electri-
IMPORTANT
It is recommended that you flush the membrane
cartridge first, without the carbon cartridge
installed in the Carbon Filter Housing, followed
by flushing the carbon cartridge. This prevents
the shipping/storage solution in the membrane
cartridge from entering the carbon cartridge and
ensures that the system produces the highest
quality water.

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 ounce
(30 ml) of bleach will be sufficient to sanitize the sys-
tem.

Filtration Process
Water filtration in the UF-216 is accomplished using
two modes: Flush Interval Mode, shown as Fi on the
LED Display and Flush Duration Mode (Fd on LED dis-
play). During the Flush Interval, 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 accom-
plished through the Flush Duration Mode. During
this mode, the drain valve opens and flushes the
membrane to remove debris collected inside the
membrane walls.
NOTE: Both the Flush Interval Mode and the Flush
Duration Mode can be automated by programming
the timer. During the Flush Interval Mode, the valve
is not powered in order to keep water filtering during
a power outage.

is depressed. (FL will flash on LED.) Releasing the but-
ton closes the drain and puts the unit back into startup
mode. After ten seconds, if the start button is not pressed
the unit automatically returns to the Flush Interval Mode
(Fi).

MAINTENANCE
The filtration system is designed to require very little
maintenance. To ensure that the water is of the highest
quality, occasionally some service is required.
Manual Flushing
NOTE: Manual flushing only works when the unit is
in Flush Interval mode (Fi).
While the unit is in Flush Interval mode (decimal point
flashing), hold the Start button down for 6-7 seconds
until the LED displays FL (Figure 14).
Continue holding the button down to keep the drain
open. The drain will remain open for as long as the
Start button is pressed (FL will flash on the LED dis-
play).
Releasing the Start Button closes the drain and puts
the unit back into start up mode. After ten seconds, if
the Start Button is not pressed the unit automatically
returns to Flush Interval mode (Fi).
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.
NOTE: This is the time between flushing, not a time-
of-day setting.
Over time, it is possible that the system flush will 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
The UF-216 system uses two types of filtration: Carbon
Block filtration and capillary membrane filtration. While
the filtration system is designed for long life, eventually
the cartridges will need to be replaced.
CHANGING THE CARBON FILTER CARTRIDGE
To change the Carbon Filter Cartridge, follow the steps
under Install and Flush the Carbon Filter Cartridge
in the Installation section of this manual.
CHANGING THE CAPILLARY MEMBRANE FILTER
CARTRIDGE
1. Open the faucet or tap closest downstream to the
filtration system and close the inlet water valve
and allow the system to depressurize.
2. 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.
3. Press and hold the Start button to help drain the
system.
4. Reattach the cap on the strainer when the water
flow stops. Unplug the power cord.
5. 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.
6. Disconnect the permeate port connection.
7. Using a screwdriver, remove the screws from the
cartridge bracket and set the bracket and screws
aside.
8. Unscrew the cartridge end caps from the car-
tridge, being careful to retain the O-rings from
each cap. Set the O-rings aside.
9. Install a new cartridge to the system using the
cartridge bracket and screws saved from Step 8.
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. 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
system may require sanitization. It is recommended
that the system and downstream plumbing be sani-
tized at least once a year. When necessary, follow the
Sanitizing the System and Lines procedure in the
Installation section of this manual.
