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).

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.

MAINTENANCE
1. Turn off water to the system by closing the Inlet Ball
Valve.
2. Press the FLUSH button to flush the system and relieve
pressure. Repeat several times to ensure permeate
tank is empty.
3. 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 fitting.
4. With the collet pushed in place, pull the tubing from the
fitting with your right hand.
NOTE: Water may drain from the tubing as it is removed.
NOTE: Make sure there is enough room next to the system
to remove the cartridge.
5. Remove the Snap Ring (Figure 7) 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.
6. Remove the End Cap, End Cap O-Ring, and Cartridge
(Figure 7) from the housing.
NOTE: If the Cartridge does not easily come out of the
Housing, remove the opposite End Cap for assistance
during Step 5.
7. Inspect the Large End Cap O-rings and End Cap O-ring
for nicks or cuts. Replace as needed.

8. 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.
9. Record the serial number of the new cartridge. The
cartridge serial number is engraved on one end of the
outer tube (for example: 05K 12013).
10. Install the End Cap O-ring on the End Cap and insert
the Large End Cap into the end of the new cartridge.
11. Position the new cartridge and End Cap at the housing
and gently insert into the housing.
12. Press the End Cap into position until it is fully seated
and the Snap Ring groove is visible.
13. Install the Snap Ring by guiding the non-lugged end
into the groove first, 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.

14. Reattach the tubing that was removed in Steps 3 and 4.
Be sure the tubing is pushed past the O-ring.
NOTE: Make sure the fitting is completely inserted onto
the tubing past the O-ring. A loose connection results in
leaking at the point of connection.
15. Rinse the new Ultra Filter Cartridge before placing the
system back into operation. Follow the Rinsing the
Ultra Filter Cartridge and Sanitizing the System
and Lines procedures in the Installation section of this
manual to complete the cartridge change.
16. When rinsing is complete, repressurize the system.
System Sanitization
The system and downstream plumbing should be sanitized
every six months. When necessary, follow the procedure in
Sanitizing the System and Lines in the Installation section
of this manual.

MAINTENANCE (continued)
Changing the Interval Setting
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.
Though not recommended, the interval setting on the
Universal Pulse Controller can be changed. If the setting must
be changed, use the chart below. Press and hold the corresponding button. After 5 seconds, the Button LED will turn on.
After 10 seconds, the Flush LED will also turn on.

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.
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
• Source of compressed air (manual bicycle tire pump or
air compressor)
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.
12 hours D 5 seconds On Off
24 hours D 10 seconds On On
Figure 8. Universal Pulse Controller
CAUTION
Be careful when adding air to the tank. Do NOT add too
much air pressure to the tank.
1. Depressurize and 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 pre-charge
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 28-31
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.
6. Pressurize system.
