WS1CS & WS1.25CS Manual

Control Valve Function and Cycles of Operation

This glass

lled Noryl

(or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate

all cycles of a water softener or

lter. When the WS1CS or WS1.25 control valve is manufactured as a softener, the control valve

can be ordered to perform down

ow or up

ow regeneration. When the WS1CS or WS1.25CS control valve is set up as a

lter,

the control valve can be set to perform down

ow regeneration or simply backwash. The control valve can be set to regenerate on

demand (consumption of a predetermined amount of water) and/or as a time clock (passage of a particular number of days). The
control valve can be set so that a softener can meet the Water Quality As so ci a tion (WQA) Standard S100 or NSF/ANSI Standard 44
ef

ciency rating.

It is not recommended to change control valves from down

ow to up

ow brining or vice versa in the

eld. The valve bodies

for down

ow and up

ow are unique to the regeneration type and and should not be interchanged. A mismatch of valve body

and regeneration piston will result in hard water bypass during service.

The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the

of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the

ow of brine or

other regenerants. The control valve regulates the

ow 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

rmly 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 pa ra ble products currently on the market.
Control valve in stal la tion 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 power pack comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter power
pack is for dry location use only. The control valve remembers all settings 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; other values are permanently stored in the
nonvolatile memory. If a power loss lasts less than 8 hours and the time

ashes on and off, the time of day should be reset and the

non rechargeable battery should be replaced.

Table 1 shows the order of the cycles when the valve is set up as a softener. The OEM has the option of having the regenerant re

after the rinse cycle or have the regenerant pre

ll before regeneration. If the OEM chooses to have the regenerant pre

ll before

regeneration, the pre

ll starts two hours before the regeneration time set. During the 2-hour period in which the brine is being made,

treated (softened) water is still available. For example: regeneration time = 2:00 am, pre

ll option selected, down

ow softener.

Fill occurs at 12:00 a.m., start of backwash cycle occurs at 2:00 a.m. Tables 2 and 3 show the length of the cycles when different
program codes are selected.
