OPERATION

Filtration Process

Water filtration in the UF Series is accomplished using two modes:

•Flush Interval (Fi on the LED display)

•Flush Duration (Fd on LED display).

During the Flush Interval mode, water enters the inlet and flows through the filter element before exiting the Permeate outlet as usable product water. After a cer- tain period of time, depending upon water quality, the filter has to be cleaned. This is accomplished through the Flush Duration Mode. During this mode, the drain valve opens and flushes the membrane to remove debris collected inside the membrane walls.

NOTE: Both the Flush Interval Mode and the Flush Duration Mode can be automated by programming the timer. During the Flush Interval Mode, the valve is not powered in order to keep water filtering during a power outage.

LED Display

Fi - Flush Interval Mode is the time between flushings and is displayed in minutes or hours.

Fd - Flush Duration Mode is the amount of time used to flush and remove debris from filter cartridge and is displayed in seconds.

FL - Manual Flush Mode operation, solenoid is manually activated by the user.

Starting the System

Power up the unit.

The LED read-out displays the following for about two seconds each:

1.8.8

2.Fd followed by its time settings in seconds.

3.Fi and its time setting, in minutes or hours.

The Fd and Fi sequence repeats for 30 seconds after which, the unit automatically returns to the Flush Interval Mode (Fi). The time setting for Fi will be displayed and the decimal point will flash in one second intervals.

NOTE: The timer can be programmed immediately after start-up or while in Flush Interval Mode.
