CAUTION
All electrical connections must be in
accordance with local electrical codes and
any other applicable codes.
A ground fault circuit interupter (GFCI) must
be installed on the circuit to this system.
When installed on metallic plumb-
ing, a properly sized electrical bonding
jumper must be installed across the inlet
and outlet pipes serving this unit.
IMPORTANT
This equipment is to be installed to
comply with the basic plumbing code

the wrong Water Flow Regulator or without
a regulator can damage the system, cause
personal injury, and voids the warranty!

IMPORTANT SAFETY
INFORMATION
In addition to the warnings and cautions in
this manual, use the following guidelines to
safely operate the system:
y Read all instructions before
using equipment.
y Install or locate the equipment
only for its intended use as
described in this manual.
y Do NOT use corrosive chemicals
in this equipment.
y Do NOT operate this equipment
if it has a damaged cord or plug;
if it is not working properly, or if it
has been damaged or dropped.
y This equipment should be serviced
by qualied personnel only. Contact
A.J. Antunes & Co. for repair.
y Do NOT immerse cord
or plug in water.
y Keep cord away from heated surfaces.
y This equipment should be
supplied with only cold water.
y For installations in Massachusetts, the
Commonwealth of Massachusetts
Plumbing Code 248 CMR shall
be adhered to. The use of saddle
valves are not permitted. Please
consult your local plumber.
The following warnings and cautions appear
throughout this manual and should be carefully observed.
y Unplug the power cord before
performing any
service or maintenance on the unit.
y All electrical connections must be in
accordance with local electrical codes
and any other applicable codes.
y Warning electrical shock hazard.
Failure to follow these instructions
could result in serious injury or death.
y Do NOT modify the power supply
cord plug. If it does not t the
outlet, have a proper outlet
installed by a qualied electrician.
y Do NOT use an extension
cord with this unit.
y If the supply cord is damaged,
it must be replaced by the
manufacturer, its service agent,
or a similarly qualied person.
y This equipment is to be installed
to comply with the local plumbing
code and any other applicable code.
y Water pressure must not
exceed 100 psig (690 kPa). To
reduce water pressure, install
a water pressure regulator and
set to suit the application.
y The trans membrane pressure
(inlet pressure minus the
permeate water pressure) must
not exceed 45 psi (310 kPa).
y A ground fault circuit interrupter
(GFCI) must be installed on
the circuit to this system.
y When installed on metallic
plumbing, a properly sized
electrical 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), it is recommended that a suitably-sized
booster system (outlet pressure
60 psig - 100 psig max (414 kPa 690 kPa max) be installed.
Protect from becoming dry
If the membrane dries out, irreversible damage 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 temperature. 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 transportation and installation.
Protect from organic solvents and
concentrated acids
Prevent any and all contact of the membrane with strong solvents, solvents
containing chlorine, or concentrated acids.
Do NOT use strong solvents or concentrated acids on any plastic parts of the
lter system. Examples of some solvents to
avoid: acetone, methyl acetate (nail polish
remover); hexane (spot removers); turpentine, 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 1011178 Rev. D 11/16 3
OVERVIEW
The VZN system operates in two modes:
y Normal Operation Mode
y Flush 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 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 o the system during Flush
Mode. If there is a power outage 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 aect the
interval ush setting.
