These water softener systems have been tested by WQA and conform to NSF/ANSI 44 for specific performance claims as verified
and substantiated by test data. The rated salt efficiencies above were also determined in accordance with NSF/ANSI 44 and are only
valid at the salt dosage referenced above. An efficiency rated water softener is a demand initiated regeneration (DIR) softener which
also complies with specific performance specifications intended to minimize the amount of regenerant brine and water used in its
operation. Efficiency rated water softeners shall have a rated salt efficiency of not less than 3350 grains of total hardness exchanged
per pound of salt (based on NaCI equivalency) (477 grams of total hardness exchanged per kilogram of salt), and shall not deliver
more salt than its listed rating. The rated efficiency of the water softener, the salt dosage at that efficiency, the capacity at that salt
dosage and that of the efficiency is only valid at the stated salt dosage. Efficiency is measured by a laboratory test described in NSF/
ANSI 44. The test represents the maximum possible efficiency the system can achieve. Operational efficiency is the actual efficiency
achieved after the system has been installed. It is typically less than the efficiency due to individual application factors including water
hardness, water usage, and other contaminants that reduce the water softener's capacity. These systems are not intended to be used
for treating water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Refer to the system Installation and Service Manual for set-up and programming instructions. Contact your local Aerus dealer for parts
and service.

Location Selection
Location of a water conditioning system is important. The
following conditions are required:
• Level platform or floor.
Note: The WC400 System can be provided with optional leveling
feet that may be used on the two tanks. Order part number
4000409.
• Room to access equipment for maintenance and adding
regenerant (salt) to tank.
• Ambient temperatures over 34°F (1°C and below 120°F
(49°C).
• Water pressure below 125 psi (8.62 bar) and above 20 psi
(1.38 bar).
• In Canada the water pressure must be below 100 psi (6.89
bar).
• Constant electrical supply to operate the control.
• Total minimum pipe run to water heater of ten feet (three
meters) to prevent backup of hot water into system.
• Local drain for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of installation.
• Valve is designed for minor plumbing misalignments. Do not
support weight of system on the plumbing.
• Be sure all soldered pipes are fully cooled before attaching
plastic valve to the plumbing.
WARNING: Dry location use only, unless used
with a Listed Class 2 Power Supply suitable for
outdoor use.
Outdoor Locations
It is recommended that the WC400 conditioner be installed in a
protected environment.
When installing the water conditioning system outdoors, several
items must be considered:
• Moisture – The valve and control are rated for NEMA 3
locations. Falling water should not affect performance. The
system is not designed to withstand extreme humidity or
water spray from below. Examples are: constant heavy
mist, near corrosive environment, or upwards spray from
sprinkler. Ensure that the Analyzer probe access panel is
installed on the unit.
• Direct Sunlight – The materials used will fade or discolor
over time in direct sunlight. The integrity of the materials
will not degrade to cause system failures.
• Temperature – Extreme hot or cold temperatures will cause
damage to the valve or control. Freezing temperatures
will freeze the water in the valve. This will cause physical
damage to the internal parts as well as the plumbing
and conditioning resin. High temperatures will affect the
control. The display may become unreadable but the control
should continue to function. When the temperature returns
to normal operating limits, the display will re-appear.
A protective cover should assist with high temperature
applications.
• Insects – The control and valve have been designed to keep
all but the smallest insects out of the critical areas. Any
holes in the top plate can be covered with duct tape. The
top cover should be installed securely in place.
WARNING: HEAVY LIFT. Lifting unit without
assistance could result in serious injury. Use
two people, lifting aids and proper lifting
techniques when moving unit.

To assemble the system, remove the salt tank components (cover,
collar, base and brine tube assembly) from the shipping container.
The media tank can now be removed. Locate the miscellaneous
parts bag.
To assemble the Salt Tank:
1. If the floor under the salt tank is uneven, the leveling feet may
be installed. Lay the empty salt tank on its side. Press or tap
the feet into the pockets.
2. Stand the salt tank up and in position. Level as needed. The
tank has two ports that will be connected. One to a drain and
one to the valve.
3. Place the brine tube in position inside the pocket at the
bottom of the tank. Install the overflow fitting.
4. Place the tank collar over the top of the brine tube. Position
the collar and push it down into the tank. Lay the cover aside
for now.
To Assemble the Media Tank:
1. If the floor under the media tank is uneven, the leveling feet
may be installed. Slowly lay the tank on its side. Press or tap
the feet into the pockets.
WARNING: The media tank contains loose
particles that will shift. If the tank is turned
upside down or laid back quickly, the particles
may enter the valve. If this happens, the valve
may need to be disassembled and cleaned.
2. Stand the tank up and in position. Level as needed.
3. Remove cover by pressing in on the latch and lifting cover
(Figure 4). When the cover is removed, the valve is visible.
Remove the remote salt detector and the power adapter.
They should be secured to the tank collar near the inlet/outlet
connections.

Figure 4
Tank and Probe Assembly
The probes are preinstalled to the media tank. The probes are
located behind an access panel on the jacket of the media tank. To
remove the access panel, remove the four screws and washers.
Use only 100% silicone lubricant on the probe O-rings (Figure 5).
Do not allow the lubricant to come into contact with the probe
pins. Install the probe assemblies into the tank and secure with
the locking clasp (Figure 6).
Important: The pins on the probes will only fit into the bulkhead
fittings one way. The pins must go into the matching holes at the
bottom of the fitting. The probe with the shortest length of wire
must be on top.
Install the protective shield (Figure 6 ).
Note: Do not attempt to tighten or loosen the Bulkhead fittings,
as they are secured with a locking adhesive.

Water Line and Bypass Connections
A bypass valve system should be installed on all water
conditioning systems. A model 1265 bypass is included with
this system. The bypass valve isolates the conditioner from the
water system and provides unconditioned water to service during
routine maintenance and servicing procedures. See Figure 7
Model 1265 Bypass (Included) and Figure 8 Typical Three Valve
Bypass Configuration (Not provided by manufacturer).
Note: Before turning on the water to the valve, rotate the two
handles on the bypass valve 2-3 times. This will help seat the
O-rings and prevent leaking.

WARNING: Do not use tools to tighten plastic
fittings. Over time, stress may break the
connections. Hand tighten the nuts.
WARNING: Do not use petroleum grease on
gaskets when connecting bypass plumbing.
Use only 100% silicone grease products when
installing any WC400 brand valve. Non-silicone
grease may cause plastic components to fail
over time.
WARNING: The inlet water must be connected
to the inlet port of the valve. When replacing
non-WC400 valves, it is possible that the inlet
and outlet plumbing is installed in a reversed
position. Ensure that the plumbing is not
installed in the opposite order. Tank media may
be pushed into the valve.

12
Drain Line Connection
Note: Standard commercial practices are expressed here. Local
codes may require changes to the following suggestions. Check
with local authorities before installing a water conditioning
system.
1. The unit should be above and not more than 20 feet (6.1 m)
from the drain. Use an appropriate adapter fitting to connect
1/2-inch (1.3 cm) plastic tubing to the drain line connection of
the control valve.
2. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or if
the unit is located 20-40 feet (6.1 – 12.2 m) from drain, use
3/4-inch (1.9 cm) tubing. Use appropriate fittings to connect
the 3/4-inch tubing to the 3/4-inch NPT drain connection on
valve.
3. The drain line may be elevated up to 6 feet (1.8 m) provided
the run does not exceed 15 feet (4.6 m) and water pressure
at the conditioner is not less than 40 psi (2.76 bar). Elevation
can increase by 2 feet (61 cm) for each additional 10-psi (.69
bar) of water pressure at the drain connector.
4. When the 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. Tie or wire the hose in place at the drain point.
Also provide an air gap of at least 1-1/2 inch between the end
of the hose and the drain point.
5. When the drain empties into an overhead sewer line, a sink-
type trap must be used.
6. Secure the end of the drain line to prevent it from moving.
Figure 9 Drain Line Connection
WARNING: Never insert drain line directly into
a drain, sewer line or trap (Figure 9). Always
allow an air gap between the drain line and the
wastewater to prevent the possibility of sewage
being back-siphoned into the conditioner.
Regenerant Line Connections
The regenerant line from the brine tank safety brine valve (Figure
11) connects to the valve. Make sure both safety valve tube
fittings are tight. Make the connections and hand tighten.
Note: Be sure that the regenerant line is secure and free from
air leaks. Even a small leak may cause the regenerant line to
drain out, and the conditioner will not draw regenerant from
the tank. This may also introduce air into the valve causing
problems with valve operation.
Ensure that plumber tape pipe sealant is applied to the 3/8-inch
NPT regenerant line connection (Figure 10).

Overflow Line Connection
In the event of a malfunction, the regenerant tank overflow will
direct “overflow” to the drain instead of spilling on the floor. This
fitting should be on the side of the cabinet or regenerant tank,
Figure 12.
To connect the overflow line, locate the connection on side of the
regenerant tank. Insert overflow fitting into tank and tighten with
plastic thumb nut and gasket. Attach length of 1/2-inch (1.3 cm)
I.D. tubing (not supplied) to fitting and run to drain. Do not elevate
overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a
direct, separate line from overflow fitting to drain, sewer or tub
with an air gap at the drain.

Electrical Connection
Note: There are no user serviceable parts in the AC adapter,
motor or the control board.
The Analyzer control operates on a 12-volt alternating current
power supply. This requires use of the supplied AC adapter. AC
adapters are available from your supplier for different applications.
They include:
AC Adapter Input Voltage Application Part Number
Standard
wall-mount 120V 60 Hz UL listed for dry locations 1000811
Outdoor rated 120V 60 Hz
UL listed

installations
1235448
120V AC Adapters:
Make sure power source matches the rating printed on the AC
adapter.
Note: The power source should be constant. Be certain the AC
adapter is not on a switched outlet. Power interruptions longer
than eight hours may cause the control to lose the day and time
settings. When power is restored, the control will display four
dashes (- - :- -) indicating that the day and time settings must
be re-entered.

System Operation
Treated Water (Downflow)
Untreated water is conditioned as it flows through the resin bed
and up the riser.
If the model selected at first start-up was 268r, this is a system
that will refill the salt tank at the start of a regeneration cycle.
When a regeneration cycle begins, the salt tank is filled and brine
is allowed to develop before Cycle 1 starts.
Backwash (Upflow) – Cycle C1
Flow is reversed by the control valve, directed down the riser, up
through the resin bed and sent to drain. The bed is expanded and
debris is flushed to the drain.
Regenerant Draw (Downflow) – Cycle C2*
Water passes through the injector and regenerant is drawn from
the regenerant tank. The regenerant is directed to the resin bed.
The hardness ions are displaced by sodium ions. Regenerant
draw is completed when the air check closes.
Slow Rinse (Downflow) – Cycle C3*
Water flow moves the regenerant through the resin at a specific
rate and rinses to the drain. The resin is regenerated.
Repressurization – Cycle C4
Pressure is balanced in the valve before continuing the
regeneration.
Fast Rinse (Downflow) – Cycle C5
Water passes through the resin bed and up through the riser
to drain. All remaining regenerant residual is rinsed from the
resin bed.
2nd Backwash (Upflow) – Cycle C6
Flow is identical to C1 Backwash. The resin is reclassified.
2nd Rinse (Downflow) – Cycle C7
Flow is identical to C5 Fast Rinse. The resin bed is rinsed
to quality.
Regenerant Refill Last – Cycle C8
Refill last only occurs if the model selected at first power up
was 268.
Water is directed to the regenerant tank to create regenerant
for the next regeneration.

Disinfection of Water Conditioning Systems
The materials of construction in the modern water conditioning
system will not support bacterial growth, nor will these materials
contaminate a water supply. During normal use, a conditioner may
become fouled with organic matter, or in some cases with bacteria
from the water supply. This may result in an off-taste or odor in
the water.
Some conditioners may need to be disinfected after installation
and some conditioners will require periodic disinfection during
their normal life.
Depending upon the conditions of use, the style of conditioner, the
type of ion exchanger, and the disinfectant available, a choice can
be made among the following methods.
Sodium or Calcium Hypochlorite
These materials are satisfactory for use with polystyrene resins,
synthetic gel zeolite, and bentonites.
5.25% Sodium Hypochlorite
These solutions are available under trade names such as Clorox*.
If stronger solutions are used, such as those sold for commercial
laundries, adjust the dosage accordingly.
1. Dosage
• Polystyrene resin; 1.2 fluid ounce (35.5 mL)
per cubic foot.
• Non-resinous exchangers; 0.8 fluid ounce
(23.7 mL) per cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required
amount of hypochlorite solution to the well of the
regenerant tank. The regenerant tank should have
water in it to permit the solution to be carried into the
conditioner.
B. Proceed with the normal regeneration.
Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in
several forms including tablets and granules. These solid materials
may be used directly without dissolving before use.
1. Dosage
A. Two grains (approximately 0.1 ounce (3 mL)
per cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required
amount of hypochlorite to the well of the regenerant
tank. The regenerant tank should have water in it
to permit the chlorine solution to be carried into the
conditioner.
B. Proceed with the normal regeneration.

Programming Overview
The Analyzer control includes multiple program levels that allow
the Water Treatment Professional to customize the system
for many water conditions. Additionally, historical data can be
viewed allowing quick and easy troubleshooting. In most cases,
Level I programming is all that is required to set up the water
conditioning system for proper operation. A brief description of
each program level is listed below.
• Level l: Used to program control for normal applications.
• Level ll: (P-Values) Allows the installer to customize
programming for non-standard applications.
• Level lll: (C-Values) Allows the installer to adjust the length
of select cycles for non-standard applications.
• Level IV: History (H-Values) Allows access to historical
information for troubleshooting the system.
Note: If a button is not pushed for thirty seconds, the control
returns to normal operation mode.
Control Operation
Power Loss Memory Retention
The Analyzer control features battery-free Time of Day and Day of
Week retention during loss of power. A super capacitor is designed
to hold the information in memory for 8 to 24 hours depending on
the installation. If the super capacitor is exhausted, the Analyzer
control will display four dashes (- - :- -) immediately upon power
up. The Time of Day and Day of Week must be reset.
All other programmed parameters are stored in the static memory
and are retained during power outages.
Level I Programming
The Analyzer control can be quickly programmed by following
the sequential procedure on the following page. Level I program
parameters are those that can be accessed by pressing the UP or
DOWN buttons.
• Valve Type: Select 268 for traditional refilling the salt tank
last. Select 268r to have a normally dry salt tank that is
filled when the regeneration cycle starts.
• Resin Volume Setting: Set to match the volume (cubic feet)
of resin in the mineral tank.
• Time of Day: Includes PM indicator. Can be set to display as
a 24-hour clock. See Level ll Programming.
• Day of Week: Set to actual day of the week.
• Time of Regeneration: Fully adjustable. Default is 2:00 AM.
• Days Override: Range 0.5 to 99 days. Leave at 0 to disable.
• Salt Dosage: Set at pounds of salt per cubic foot of resin in
the conditioner tank.
Note: When the control is set up for a twelve-hour clock a PM
indicator will illuminate when the displayed time is in the PM
hours. There is no AM indicator.
