Control Valve General Features and Information
This fully automatic control valve is designed as the primary control center to direct and regulate all cycles of an automatic
backwashing filter.
The time clock control for performing regeneration (backwash) has two calendar options for regeneration frequency:
An option where the user can choose the number of days (1-99) between each regeneration; and
A seven-day option where the user can choose which day(s) of the week a regeneration should occur.
The control valve regulates the flow rates for backwash and rinse cycles.
The control valve uses no traditional fasteners (e.g. screws); instead clips, threaded caps and nuts and snap type latches
are used. Caps and nuts only need to be firmly hand tightened because radial seals are used. Tools required to service
the valve include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench
is available which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than
com parable products currently on the market. Control valve installation is made easy because the distributor tube can be
cut ½” above to ½” below the top of tank thread. The distributor tube is held in place by an o-ring seal and the control
valve also has a bayonet lock feature for upper distributor baskets.
The AC adapter comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter is for dry
location use only. The control valve maintains timekeeping for up to 8 hours if the power goes out and the battery is not
depleted. After 8 hours, the only item that needs to be reset is the time of day; valve status and programming are
permanently stored in the nonvolatile memory. If a power loss lasts less than 8 hours and the time flashes on and off, the
time of day should be reset and the non-rechargeable battery should be replaced.
