Overview
The VZN system operates in two
modes:
y
Normal Operation Mode
y
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.
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.
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.
NOTE:
Some units may not have the secondary TAC housing.
