Introduction
The Model 960 control provides sophisticated,
demand-based water conditioning by incorporating a
microprocessor and a water meter to electronically
monitor the amount of water used daily. This fully
programmable control allows you to fine tune the
conditioner’s operation to meet your customer’s
application. The Series 255 valve combines design
simplicity with reinforced Noryl* construction to provide
an uncommonly reliable appliance. The inherent
reliability of the system means a long life of efficient,
trouble-free water conditioning. If maintenance
becomes necessary, the Series 255/960 water
conditioning system offers a unique separation
capability illustrated in this manual.

Special Features
•
Memory Retention.
critical operating information in the control’s
memory is stored in a special electronic device.
This information includes the time of day, water
usage amounts, daily average water usage, all
programming data and the number of days since
the last regeneration. When power is restored, the
information is returned to the microprocessor and
operation res umes as if a n outag e never occurr ed.
The time of day will be late by the length of the
power outage. If an outage of one or more hours
occurs, the time of day sh ould be reset but no ot her
reprogramming is necessary. The optional
non-rechar geable b attery backup fea ture wi ll allow
the control to keep track of time and any water
usage for up to two days during a power outage.
•
Fully programmable regeneration cycle times.
The control is factory programmed with typical
regeneration cycle times for easy installation. The
control allo ws the Backwash, Rinse, and Purge
cycle times to be set by the installer to fine tune the
conditioner’s operation.
•
Automatic double regenerations for exhausted
resin beds.

control will automatically call for a second
regeneration the next day even if no water is used.
This feature is included to make sure that an
exhausted resin bed is completely recharged.
•
Selectable reserve options.
programmed to operate with one of four different
reserve options (see Parameter P15, Table 3). The
options include starting a regeneration only at a
specific time of day or having an immediate
regeneration when the capacity is exhausted. The
control can also have a fixed reserve which is a
percentage of the total system capacity or a

•

grains per gallon of hardness, pounds of salt, and

per liter of hardnes s, kilograms of salt and
kilograms of capacity for metric units (see
Parameter P12, Table 3).

conditioner if the water usage hasn’t caused a

metering system has only one moving part, t he
rotating turbine that measures water usage and
generates electrical pulses that are counted by the
microprocessor to determine the need to
regenerate.
•
Guest cycle.
achieved at any time by pressing the REGEN
button on the Model 960 front panel. It takes just a
few minutes for the regeneration to start. The
regeneration takes about two hours. This feature is
beneficial when the cust omer expects t o use mor e
than the normal amount of water; for example,
guest visits or an extra heavy laundry day.
•
Manual double regeneration.
regenerations can be run by pressing the REGEN
push button after the first regeneration has been
running for at least one minute. This can be used to
recharge the resin bed that has operated without
salt for an extended period of time.

Superior Design
• Fewer parts than any control system of
comparable function and most controls of lesser
function.
• The valve may be indexed manually with or without
power to any one of its service or regeneration
positions. The Regeneration Cycle Indicator on the
3
control face plate indicates control valve po sition.
• No dynamic seals that could cause leakage
through wear or fatigu e.
• Control accepts Noryl brass manifold or modular
bypass valve without modification, offering
complete versati lity and easy plumbing for any
installation.
• Brining control valve built into system eliminates
need for an external brine valve.
• Drain flow control is built into the valve to control
backwash and fast rinse flow rates.
Superior Operation
• Direct acting system functions independently of
water pressure. No pistons or diaphragms that
require a minimum water pressure to operate.
• Five-cycle operation provides for downflow
conditioned water, upflow backwash, downflow
brining and slow rinse, downflow fast rinse, and
refill of the brine tank.
• Valve discs are held closed by water pressure and
are leak tight. Valve seats are in a vertical position,
which is the position least vulnerable to plugging.
• System operation cannot get out of phase or
sequence. The control always returns to a fixed
conditioned water position after regeneration.
• Bypass water is automatically available during
regeneration.

unit carefully for carrier shortage or shipping damage.
Location Selection
The following considerations must be taken into
account when selecting the location for the water
conditioning system.
• Locate the system as close to a drain as possible.
• If supplementary water treating equipment is
required, make sure that adequate additional
space is available. Locate the brine t a nk in an
accessible place so that salt can be easily added.
• Do not install any unit closer than 10 feet (3 m) of
piping between the outlet of the conditioner and
the inlet of a water heater. Water heaters can
transmit heat back down the cold water pipe into
the control valve. Hot water can severely damage
the conditioner.
A 10-foot (3-m) total pipe run (including bends, elbows,
etc.) is a reasonable distance to prevent hot water
damage. A positive way to prevent hot water from
flowing from a heat source to the conditioner is to
install a check valve in the soft water piping from the
conditioner. If a check valve is installed, make sure that
the water heating unit is equipped with a properly rated
temperature and pressure safety relief valve. Always
conform to local codes.
• Do not locate the unit in an area where the
temperature ever falls below 34

Where drain line is elevated but empties into a drain
below the level of the control valve, form a 7-inch
(18-cm) loop at the far end of the line so that the bottom
of the loop is level with the drain line connection. This
will provide an adequate siphon trap (Figure 5).
Where a drain empties into an overhead sewer line, a
sink-type trap must be used.

Troubleshooting
Brine Tank Overflow Line Connection
In the event of a malfunction, the brine tank overflow
connection directs overflow to the drain instead of
spilling it on the floor where it could cause water
damage. Complete the foll owing step s to conn ect the
overflow fitting to the brine tank:
1. Locate the fitting hole on the side of the br ine tan k.
2. Insert the overflow fitting (not supplied) into the
tank and tighten with the plastic thumb nut and
gasket as illustrated in Figure 6.
3. Attach a length of 1/2-inch (1.3-cm) tubing (not
supplied) to the fitting and run to the drain.
Figure 6 - Overflow Line Connection
Do not elevate the overflow line higher than
Note:
3 inches (7.6 cm) below the bottom of the overflow
fitting. Do not tie into the drain line of the control unit.
The overflow line must be a direct, separate line from
the overflow fitting to the drain, sewer , or tub. Allow an
air gap as in the drain line connection, Figure 5.
Placing Conditioner into Operation
Initial Start-Up
After the water conditioning system is installed, the
conditioners should be disinfected before they are
used to treat potable water. Refer to the
Water Conditioners
the following step s to place the conditioner into
operation:
1. Remove the rear valve cover by pulling back on the
tab located on the lower rear edge of th e cover.
Next, lift the cover off the valv e, Figure 10.
