IMPORTANT SAFETY INFORMATION (continued)

VZN SERIES

Protect from becoming dry

If the membrane dries out, irreversible damage to the Ultra
Filter membrane may result. Protect the filter 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 100°F (38°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 filter 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 filter system. Examples of some solvents to avoid:
acetone, methyl acetate (nail polish remover); hexane (spot
removers); turpentine, toluene (paint thinners); dry cleaning
solutions, insecticides.

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 Flow Regulator Assemblies are NOT interchange­able. Operating the system with the wrong Water Flow
Regulator or without a regulator can damage the sys­tem, cause personal injury, and voids the warranty!

CAUTION

All electrical connections must be in accordance with
local electrical codes and any other applicable codes.

A ground fault circuit interrupter (GFCI) must be
installed on the circuit to this system.

When installed on metallic plumbing, a properly sized
electrical bonding jumper must be installed across the
inlet and outlet pipes serving this unit.

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 flushed clean before installing the fil­ter. All plastic parts of the filter 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.

VZN SERIES

OPERATION

Overview

The VZN 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 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).

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-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 coffee stirrer to dissolve. When added to the
system, 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 and TAC
Cartridge from the system BEFORE Sanitizing.

1. Follow the steps in the Rinsing the Ultra Filter
Cartridge in the Installation section of this manual.

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.

Semi-Annual Tasks

Check Permeate Tank Air Pre-Charge

It is recommended the permeate tank air charge be
checked every six months.

Tools and supplies required:

• Air Pressure Gauge, 5‒40 psi range (0.3‒2.7 bar)
with tire valve (Schrader Valve) connection

CAUTION

Air pre-charge should only be checked and adjusted
under zero system pressure. The system must be
depressurized before checking the tank pre-charge.
Do NOT adjust the tank air pre-charge with the system
under pressure.

CAUTION

Be careful when adding air to the tank. Do NOT add too
much air pressure to the tank.

• Source of compressed air (manual bicycle tire
pump or air compressor)

1. Refer to Figure 1. Depressurize the system by
closing the Inlet and Outlet Valves and opening
the Rinse Valve. Make sure the Permeate Tank is
fully drained.

2. Unscrew the protective cap from the air valve on
the tank.

3. Use the pressure gauge to check the tank pre­charge for pressure.

NOTE: If any water comes out the air valve, the tank

bladder has ruptured and the tank needs to be
replaced.

4. The permeate tank should have a pressure of 28­31 PSI.

• To add pressure to the permeate tank, use a

manual bicycle tire pump or other source of
compressed air.

• To release pressure from the permeate tank,

press the center pin on the air inlet valve.

5. Once the permeate tank is at 28-31 PSI, replace
the protective cap on the air valve.
