Operation; Overview; Manual Flushing - Vision VZN-441H Owner's Manual

VZN H SERIES

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 enter-
ing 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 sys-
tem 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).
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.

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.
