rupter (GFCI) must be installed
on the circuit to this system.
yWhen installed on metallic
plumbing, a properly sized elec-
trical bonding jumper must be
installed across the inlet and
outlet pipes serving this unit.
NOTE: If the inlet water pressure is less
than 50 psig (345 kPa), install a
suitably sized booster system
(outlet pressure 60 psig - 100
psig max (414 kPa - 690 kPa
max).
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.

Mounting the System
NOTE: Use caution when lifting and
mounting the system. The system
MUST be mounted using the
provided Mounting Bracket.
The VZN system comes with a Mounting
Bracket. When mounting the system, pay
attention to the following guidelines:
yAllow sucient access for car-
tridge replacement. The VZN-
441VA should be mounted with
40 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 consum-
able water
ltration processes.
yMount the system with the provided
Mounting Bracket and hardware ca-
pable of supporting 120 lbs. or more.
ySecure the Mounting Bracket into
wall studs or with the appropriate
heavy duty mounting hardware.
The system is pre-assembled to a Back Plate.
The Back Plate has mounting holes across
the bottom portion to secure the bottom of
the system to the wall. Some of the bottom
mounting holes may be obscured. Plan your
mounting accordingly.
Follow these steps to secure the Mounting
Bracket to the wall and seat the VZN system:
1. Use a stud nder and level to attach
the Mounting Bracket securely to the
wall with the appropriate
mounting hardware (Figure 2).
2. The Mounting Bracket is designed so
that the VZN
system can be lifted and hung on the
Mounting Bracket. With assistance,
lift the system and seat it onto the

Drain Valve Connection
The drain is for ushing particle buildup out
of the system during self cleaning.
1. Cut a length of tubing (not supplied)
so it reaches the drain from the Drain
Valve.
2. Connect one end of the hose to the
Drain Valve with an appropriate t-
ting (not supplied) (Figure 3).
3. Direct the other end of the hose to
the drain (Figure 3).
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 pres-
sure, inlet pipe size, and system.
yThe drain line leading out of the
system must be as short as pos-
sible and slope downwards
without any kinks or loops.
yThe drain line plumbing must be po-
sitioned and secured at least 2 inches
above the drain (Figure 4). This air gap
protects the system from contamina-
tion 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.

Sanitizing the System and Lines
The plumbing must be sanitized to elimi-
nate 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-s-Triazinetrione
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 coee
stirrer to dissolve. When added to the sys-
tem, this will create a 60-100 ppm chlorine
solution.
NOTE: Follow the handling and safety
instructions supplied with the
sanitizer.
NOTE: If installed, remove the Carbon
Element from the system BEFORE
Sanitizing.
1. Follow the steps in the Rinsing the
Ultra Filter Cartridge in the Installa-
tion section of this manual.
2. Turn o the water to the system.

OPERATION
Overview
The VZN 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 Universal
Pulse 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).
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 will automatically return to Normal
Operation Mode.
NOTE: A manual ush will not aect the
interval ush setting.
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.

MAINTENANCE
Replacing the Ultra Filter
Cartridge
NOTE: Always install new Carbon Ele-
ment after replacing the Ultra
Filter Cartridge.
1. Turn o water to the system by clos-
ing the Inlet Ball Valve and Outlet
Ball Valve.
2. Press the FLUSH button to ush the
system and relieve pressure. Repeat
several times to ensure permeate
tank is empty.
3. Remove the Carbon Element if pres-
ent.
4. Locate the long hooked tubing on
the right and disconnect the long
end from the tee by pushing the
collet squarely against the face of
the tting.
5. With the collet pushed in place, pull
the tubing from the tting with your
right hand.
NOTE: Water may drain from the tubing
as it is removed. Make sure there
is enough room next to the sys-
tem to remove the cartridge.
6. Remove the Snap Ring (Figure 8)
from the Ultra Filter Housing. Grab
the raised lug with a pair of pliers
and pull towards the center of the
End Cap and away. The Snap Ring
should lift out of its groove.
7. Remove the End Cap, End Cap O-
Ring, and Cartridge (Figure 8) from
the housing.
NOTE: If the Cartridge does not easily
come out of the Housing, remove
the opposite End Cap for assis-
tance during Step 5.
8. Inspect the Large End Cap O-rings
and End Cap O-ring for nicks or cuts.
Replace as needed.
9. Lubricate all O-rings with a food-
grade silicone lubricant. Apply a light
coating of lubricant to the inside
center tube at both ends of the new
cartridge.
10. Record the serial number of the new
cartridge. The cartridge serial num-
ber is engraved on one end of the
outer tube (for example: 05K 12013).
11. Install the End Cap O-ring on the End
Cap and insert the Large End Cap
into the end of the new cartridge.
12. Position the new cartridge and End
Cap at the housing and gently insert
into the housing.
13. Press the End Cap into position until
it is fully seated and the Snap Ring
groove is visible.
14. Install the Snap Ring by guiding the
non-lugged end into the groove
rst, pushing outward and working
around the ring until it snaps into
place.
NOTE: Make sure that the Snap Ring is
fully seated before turning the
water on.
15. Reattach the tubing that was re-
moved in Steps 3 and 4. Be sure the
tubing is pushed past the O-ring.
NOTE: Make sure the tting is complete-
ly inserted onto the tubing past
the O-ring. A loose connection
results in leaking at the point of
connection.
16. Rinse the new Ultra Filter Cartridge
before placing the system back into
operation. Follow the Rinsing the
Ultra Filter Cartridge, Sanitizing the
System and Lines, and Rinsing the
Carbon Element procedures in the
Installation section of this manual to
complete the cartridge change.
17. When rinsing is complete, repressur-
ize the system by opening the Outlet
Ball Valve then opening the Inlet Ball
Valve.

ing the System and Lines in the Installation
section of this manual.
Rinsing and Replacing the Carbon
Element
1. Turn o the water to the system by
closing the Inlet Ball Valve and Outlet
Ball Valve.
2. Open the Rinse Ball Valve and allow
the system to drain to ensure the
permeate tank is empty.
3. Press and hold the RED Pressure Re-
lief Button on the top of each of the
Carbon Element Housing to lower
the water level inside the housings
by 2 to 3 inches.
4. Remove the Carbon Element Hous-
ing (Figure 9).
5. Empty any water into a drain and dis-
card the old Carbon Element.
6. Inspect the O-ring on the Carbon
Element Housing (Figure 9). Replace
the O-ring if it is cracked, twisted, or
missing.
7. Lubricate the O-ring with an ap-
proved food grade
lubricant and install into the Carbon
Element Housing.

the Carbon Element Housing.
NOTE: Make sure the Gasket remains in
place in the recessed grooves on
both ends of the Carbon Element.
9. Screw the Carbon Element Housing
(containing the Carbon Element) into
place on the Carbon Element Head.
The Housing will come to a hard stop
at the end of the thread. Use a Filter
Wrench if necessary.
NOTE: Do NOT overtighten the Carbon
Element Housing.
10. Direct water from the Rinse Ball Valve
to a drain.
NOTE: Direct the Rinse Ball Valve to a
drain. Do NOT use the water re-
sulting from the ush procedure.
