16 PWSR Series Softeners
System Components Described
The drain line flow control can be installed in the standard 1/4" drain
line elbow, which accommodates 5/8" poly tube or 3/4" NPT drain
line connections . The optional nut and poly tube insert for the 3/4"
drain line elbow is designed for use with flexible poly tube only . The
3/4" drain line elbow can be rotated 180 degrees so the outlet can
be orientated to the nearest drain . The same retainer is used for all
drain line flow controls for the 3/4" fitting .
Water Meter or Meter Plug
The water meter is installed on the outlet side of the control valve .
The water meter uses a turbine to total gallons of treated water . The
turbine rotates with the flow of water and reports its rate of rotation
through Hall-effect 8 circuitry to the printed circuit (PC) board . This
rotation permits the PC board to record the total volume of treated
water and the flow rate . The small centrally located magnet is shield-
ed from water, which reduces substantially iron-fouling problems
with the turbine . The turbine is accurate to within ± 5% over a wide
operating flow rate range (0 .25 gpm up to control valve maximums)
and has a very low pressure drop . Water used for regeneration is
not metered . If the control valve is set to prefill the regenerant, water
used between the prefill cycle up to the start of the regeneration
cycle is metered . If the control valve is in regeneration mode (e .g . a
backwash cycle) and there is a water demand that water usage is
not metered .
When facing the front of the control valve, the water meter is po-
sitioned on the left-hand side of the control valve . Allow sufficient
clearance to clean and repair the water meter with out disconnecting
the plumbing or disassembling any other parts of the control valve .
A unique feature of this control valve is the ability to display actual
water usage for the last 63 days . The values are initially stored as "_"
because it is unknown . As days pass values are stored as “O” for
no flow or the actual number of -gallons . The counting of the gallons
starts 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 before
yesterday, etc . As new values are added the oldest history disap-
pears .
Another unique feature is that the valve automatically calculates a
reserve capacity when set up as a softener with “Gallons Capacity”
set to “AUTO” . The reserve capacity for a given day of the week is
the middle value stored for the last three non-trivial water usages
(i .e . less than 20 gallons day) in seven-day intervals which is then
adjusted either upward or downward depending upon the difference
between today’s water usage and the estimated reserve capacity .
Installation Fitting Assemblies
The installation fittings are used to connect the optional bypass or
the control to the plumbing system . There are four installation-fitting
assemblies available:
1 . 1" NPT elbow
2 . 3/4" & 1" PVC solvent weld elbow fitting
3 . 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" NPT
connection to the inlet and/or outlet which can be used for a RO
feed, test ports, pressure tap ports, etc .
The installation fitting assemblies are sold in pairs and consist of two
fittings, two nuts, two split rings and two o-rings . The installation
fitting assemblies and the bypass valve are sold separately from the
control valve .
Bypass Valve
The bypass valve is typically used to isolate the control valve from
the plumbing system’s water pressure in order to perform control
valve repairs or maintenance . The W100SM bypass valve is par-
ticularly unique in the water treatment industry due to its versatility
and state of the art design features . The 1" full flow bypass valve
incorporates four positions including a diagnostic position that allows
service personal to work on a pressurized system while still provid-
ing untreated bypass water to the facility or residence . Its completely
non-metallic, all plastic design allows for easy access and service-
ability without the need for tools .
The bypass body and rotors are glass filled Noryl and the nuts and
caps are glass filled polypropylene . All seals are self-lubricating
EPDM to help prevent valve seizing after long periods of non-use .
Internal o-rings can easily be replaced if service is required .
The bypass consists of two interchangeable plug valves that are
operated independently by red arrow shaped handles . The handles
identify the flow direction of the water . The plug valves enable the
bypass valve to operate in four positions .
1 .
Normal Operation Position:
The inlet and outlet handles point
in the direction of flow indicated by the engraved arrows on
the control valve . Water flows through the control valve during
normal operation and this position also allows the control valve
to isolate the media bed during the regeneration cycle .
(See Figure 17)
2 .
Bypass Position:
The inlet and outlet handles point to the
center of the bypass, the control valve is isolated from the water
pressure contained in the plumbing system . Untreated water is
supplied to the plumbing system . (See Figure 18)
3 .
Diagnostic Position:
The inlet handle points in the direction of
flow and the outlet handle points to the center of bypass valve,
system water pressure is allowed to the control valve and the
plumbing system while not allowing water to exit from the control
valve to the plumbing . (See Figure 19)
4 .
Shut Off Position:
The inlet handle points to the center of the
bypass valve and the outlet handle points in the direction of flow,
the water is shut off to the plumbing systems . If water is available
on the outlet side of the softener it is an indication of water by-
pass around the system (i .e . a plumbing connection somewhere
in the building bypasses the system) . (See Figure 20)
* Some semiconductor materials exhibit a phenomenon in the presence of a
magnetic field that is adaptable to sensing devices . When a current is passed
through one pair of wires attached to a semiconductor, another pair of wires
properly attached and oriented with respect to the semiconductor will devel-
op a voltage proportional to the magnetic field present and the current in the
other pair of wires . Holding the exiting current constant and moving a perma-
nent magnet near the semiconductor produces a voltage output proportional
to the movement of the magnet . Hall-effect devices provide a high-speed
response, excellent temperature stability and no physical contact .
** Has not been tested for compliance with California Proposition 65 so this
fitting should not be installed in California .
