Control Valve Function And Cycles Of Operation - Water Depot Deluxe Series Owner's Manual

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 water softener or filter. When the WS1MR control valve is manufactured as a softener,
the control valve can be ordered to perform downflow or upflow regeneration. The WS1.25MR control valve is only
available in downflow regeneration. When the WS1MR or WS1.25MR control valve is set up as a filter, the control
valve can be set to perform downflow 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 Association (WQA)
Standard S100 or NSF/ANSI Standard 44 efficiency rating.
It is not recommended to change control valves from downflow to upflow brining or vice versa in the field.
The valve bodies for downflow and upflow are unique to the regeneration type 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 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 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 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 two hours if the
power goes out. After two hours, the only item that needs to be reset is the time of day; all other values are
permanently stored in the non-volatile memory. The control valve does not need batteries.
The control valve‟s unique design and electronics allow the OEM to select:
1. a pre or post fill option with up or down flow and adjust the length of the cycles; or
2. a pre or post fill option, select a program code that has a preset cycle order/value and adjustable fill cycle.
Tables 1 and 2 show examples when the valve is set up as a softener or a filter.
