The default settings for backwash (25 minutes) and fast rinse (5 minutes) cycles of recharge are factory set
for maximum performance of the filter. Use the following procedures to check for correct cycle times, or to
change if desired. However, only trained technicians should change the time settings.
NOTE:
Fill and brine times are adjustable, but preset at the factory to zero minutes. It is recommended to leave
these settings as preset, unless the filter is used in a custom application by the installer.

GENERAL INFORMATION
The air injector adaptor is installed between the filter valve and mineral tank. A pump injects air into the iron
filter through the adaptor. The air oxidizes the iron. The oxidized iron is then mechanically filtered by the filter
mineral bed. The solenoid valve allows excess air to vent from the tank.
SERVICE, BACKWASH AND FAST RINSE CYCLES
SERVICE (See Figure 11):
Unfiltered water enters the valve inlet port. Internal valve porting routes the water
into the mineral tank. The water is filtered as it passes through the mineral bed, then enters the bottom distribu-
tor. Filtered water flows back into the valve and out the valve outlet, to the house filtered water pipes.
In time, the filter needs cleaning to remove sediments, dirt, iron, etc., from the mineral bed. This cleaning is
done in two stages, or cycles, called backwash and fast rinse. It is started automatically by the timer.
BACKWASH (See Figure 12):
The timer starts the valve motor and moves the valve into backwash position.
Water is routed down and out the bottom distributor, up through the mineral bed, and out of the filter to the
drain. The fast flow (controlled by a flow plug in the drain fitting) flushes dirt, sediments, iron deposits, etc.
to the drain. The mineral bed is lifted and expanded for maximum cleaning.
FAST RINSE (See Figure 13):
Valve rotation positions the inner discs so water flow enters the mineral tank
through the top, and exits at the bottom, to the drain. The fast flow of water downward, packs the mineral
bed and prepares it for return to service.
The timer energizes the valve motor again to return the valve to service.
