CONTROL VALVE FUNCTION AND CYCLES OF OPERATION
This glass filled Noryl1 (or equivalent) fully automatic control valve is designed as the primary
control center to direct and regulate all cycles of a downflow regeneration water softener or filter.
The time clock control valve can be set to perform downflow regeneration or simply backwash. The
time clock control valve has two calendar options for regeneration frequency:
• An option where the user can choose the number of days (1-99) between each regeneration;
• A seven-day option where the user can choose which day(s) of the week a regeneration should
occur.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is
capable of routing the flow of water in the necessary paths to regenerate or backwash water
treatment systems. The injector regulates the flow of brine or other regenerants. The control valve
regulates the flow rates for backwashing, rinsing, and the replenishing of treated water into a
regenerant tank, when applicable.
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 comparable
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.
The user can initiate manual regeneration. The user has the option to request the manual
regeneration at the delayed regeneration time or to have the regeneration occur immediately.
Simultaneously press the ▲ and ▼ buttons to start a regeneration at the next delayed regeneration
time. If a regeneration is to occur today an arrow will point to REGEN. For immediate regeneration,
simultaneously press and hold the ▲ and ▼ buttons for three seconds.
When in regeneration, step through the different regeneration cycles by pressing the▲ or ▼
buttons.
