16 PWSR Series SoftenersSystem Components DescribedThe drain line flow control can be installed in the standard 1/4" drainline elbow, which accommodates 5/8" poly tube or 3/4" NPT drainline connections The optional nut and poly tube insert for the 3/4"drain line elbow is designed for use with flexible poly tube only The3/4" drain line elbow can be rotated 180 degrees so the outlet canbe orientated to the nearest drain The same retainer is used for alldrain line flow controls for the 3/4" fittingWater Meter or Meter PlugThe water meter is installed on the outlet side of the control valveThe water meter uses a turbine to total gallons of treated water Theturbine rotates with the flow of water and reports its rate of rotationthrough Hall-effect 8 circuitry to the printed circuit (PC) board Thisrotation permits the PC board to record the total volume of treatedwater and the flow rate The small centrally located magnet is shield-ed from water, which reduces substantially iron-fouling problemswith the turbine The turbine is accurate to within ± 5% over a wideoperating flow rate range (0 25 gpm up to control valve maximums)and has a very low pressure drop Water used for regeneration isnot metered If the control valve is set to prefill the regenerant, waterused between the prefill cycle up to the start of the regenerationcycle is metered If the control valve is in regeneration mode (e g abackwash cycle) and there is a water demand that water usage isnot meteredWhen facing the front of the control valve, the water meter is po-sitioned on the left-hand side of the control valve Allow sufficientclearance to clean and repair the water meter with out disconnectingthe plumbing or disassembling any other parts of the control valveA unique feature of this control valve is the ability to display actualwater usage for the last 63 days The values are initially stored as "_"because it is unknown As days pass values are stored as “O” forno flow or the actual number of -gallons The counting of the gallonsstarts at the regeneration time If no regeneration time can be set(i e when the valve is set for immediate regeneration) the counting,of gallons starts at 12 a m Day 1 is yesterday, day 2 the day beforeyesterday, etc As new values are added the oldest history disap-pearsAnother unique feature is that the valve automatically calculates areserve capacity when set up as a softener with “Gallons Capacity”set to “AUTO” The reserve capacity for a given day of the week isthe middle value stored for the last three non-trivial water usages(i e less than 20 gallons day) in seven-day intervals which is thenadjusted either upward or downward depending upon the differencebetween today’s water usage and the estimated reserve capacityInstallation Fitting AssembliesThe installation fittings are used to connect the optional bypass orthe control to the plumbing system There are four installation-fittingassemblies available:1 1" NPT elbow2 3/4" & 1" PVC solvent weld elbow fitting3 1" straight brass sweat fitting **4 3/4" straight brass sweat Fitting **Both elbow fittings have a unique drill out feature to allow a 1/4" NPTconnection to the inlet and/or outlet which can be used for a ROfeed, test ports, pressure tap ports, etcThe installation fitting assemblies are sold in pairs and consist of twofittings, two nuts, two split rings and two o-rings The installationfitting assemblies and the bypass valve are sold separately from thecontrol valveBypass ValveThe bypass valve is typically used to isolate the control valve fromthe plumbing system’s water pressure in order to perform controlvalve repairs or maintenance The W100SM bypass valve is par-ticularly unique in the water treatment industry due to its versatilityand state of the art design features The 1" full flow bypass valveincorporates four positions including a diagnostic position that allowsservice personal to work on a pressurized system while still provid-ing untreated bypass water to the facility or residence Its completelynon-metallic, all plastic design allows for easy access and service-ability without the need for toolsThe bypass body and rotors are glass filled Noryl and the nuts andcaps are glass filled polypropylene All seals are self-lubricatingEPDM to help prevent valve seizing after long periods of non-useInternal o-rings can easily be replaced if service is requiredThe bypass consists of two interchangeable plug valves that areoperated independently by red arrow shaped handles The handlesidentify the flow direction of the water The plug valves enable thebypass valve to operate in four positions1 Normal Operation Position: The inlet and outlet handles pointin the direction of flow indicated by the engraved arrows onthe control valve Water flows through the control valve duringnormal operation and this position also allows the control valveto isolate the media bed during the regeneration cycle(See Figure 17)2 Bypass Position: The inlet and outlet handles point to thecenter of the bypass, the control valve is isolated from the waterpressure contained in the plumbing system Untreated water issupplied to the plumbing system (See Figure 18)3 Diagnostic Position: The inlet handle points in the direction offlow and the outlet handle points to the center of bypass valve,system water pressure is allowed to the control valve and theplumbing system while not allowing water to exit from the controlvalve to the plumbing (See Figure 19)4 Shut Off Position: The inlet handle points to the center of thebypass valve and the outlet handle points in the direction of flow,the water is shut off to the plumbing systems If water is availableon the outlet side of the softener it is an indication of water by-pass around the system (i e a plumbing connection somewherein the building bypasses the system) (See Figure 20)* Some semiconductor materials exhibit a phenomenon in the presence of amagnetic field that is adaptable to sensing devices When a current is passedthrough one pair of wires attached to a semiconductor, another pair of wiresproperly attached and oriented with respect to the semiconductor will devel-op a voltage proportional to the magnetic field present and the current in theother pair of wires Holding the exiting current constant and moving a perma-nent magnet near the semiconductor produces a voltage output proportionalto the movement of the magnet Hall-effect devices provide a high-speedresponse, excellent temperature stability and no physical contact** Has not been tested for compliance with California Proposition 65 so thisfitting should not be installed in California
