INSTALLATION INSTRUCTIONS
GENERAL INFORMATION
Before beginning installation, thoroughly review the following instructions to familiarize yourself with the general place-
ment and identication of all components. These instructions are written for a single unit installation, but they also
generally apply to twin and triple units.
Refer to specic equipment layout drawing, water meter installation instruction, and interconnecting electrical wiring
diagram for your system.
Catalog softeners are shipped fully assembled with face piping and controllers. Care must be taken not to dam-
age valves or controllers during uncrating and installation. During unpacking the brine tank miscellaneous parts are
shipped inside the brine tank. These parts include hardness test kit, injectors, extra manuals and other parts that may
apply to your particular system. Care should be taken when unpacking the brine tank.
NOTES:
• Install the piping conforming to federal, provincial, and local codes.
• Union or anges are recommended at the control valve’s inlet, outlet, and drain connections
• To enhance the monitoring of the system’s performance sample valves and pressure gauges are be installed at
the inlet and outlet piping to each control valve.
• If distance of drain line is over a 10 ft. vertical, or 25 ft. horizontal run, increase drain line one pipe size over that
provided on the control valve.
• Do not make a direct connection to the drain. Provide an air gap of at least four times the diameter of the pipe to
conform to sanitation codes and to permit observation of the ow.
• It is not recommended that an overhead or a long horizontal drain run be used. The increased backpressure will
cause problems when drawing brine.
PIPING INSTALLATION:
1. Install piping as shown on the layout drawing. Include unions and shut-o󰀨 valves on the inlet and outlet of each
softener. Also, include a shut-o󰀨 valve for each injector provided with the system. It is recommended that a union
be installed in each softener drain-line to facilitate cleaning the backwash ow control.
2. Do not reduce drain-line pipe size. Do not install a shut o󰀨 valve in the drain-line. Provide an air gap in the drain
line in accordance with local codes (minimum four (4) pipe diameters).
3. If your system has a water meter thoroughly read the meter instructions manual located in the back of this manual
before installing any water meters or ow sensors,. Water meters typically must be installed in a particular manner
(i.e. horizontal, plane or with recommend pipe lengths) to function properly.
4. After the piping has been completed, make sure to close all isolation valves.

INSTALLATION INSTRUCTIONS
SOFTENER LOADING
Do not begin loading until you have conrmed all of the
required media is on site. Locate your unit on the Speci-
cation Table for the correct amount of gravel and resin per
tank and separate quantities.
Before loading, visually check the lower distributor for ship-
ping damage. All radial arms and baskets strainers are in
place and pointing downward. Tighten any loose laterals.
Do not load tank if there is damage is evident. Call the fac-
tory if any damage is observed.
Care should be exercised in the loading of the gravel in
order to insure that the distributors are not damaged. The
equipment provided has a PVC lower distributor system.
GRAVEL LOADING - (Load First)
1. Slowly open the inlet valve and ll the tank half way or
as full as possible with water. There might be a ow of
water to drain.
2. Slowly and gently pour the gravel marked for the min-
eral tank into the unit.
3. Drain the tank down until the gravel and water levels
are the same.
4. Carefully level the gravel before loading the resin.
RESIN LOADING
1. Reopen the inlet valve and ll the tank to1/3 to 1/2 full of water.
2. Pour the quantity of resin marked for the tank in through the top opening.
3. Reopen the inlet valve and ll the tank with water to the top access opening.
4. Close and secure the top access opening.
5. Open inlet valve and continue to ll the tank with water until it is fully
pressurized.

INSTALLATION INSTRUCTIONS
BRINE TANK INSTALLATION
1. The brine tank should be installed on a smooth level surface. If none is available, the tank should be placed on a
smooth piece of exterior plywood and leveled by placing shims underneath the plywood.
2. Make sure that the salt shelf inside the tank is level and that the brine well is near to vertical as possible. Check
the specications table and make sure that the oat setting is the proper height for the model provided. Brine
tanks are shipped with the oat set for maximum salting. If incorrect, slide the oat to the proper setting. Float
should be approximately one inch above grid plate.
3. Place brine valve into the brine well and set at the bottom of the brine tank. Note: If minimum brine draw is de-
sired, remove the pipe nipple and coupling from the brine assembly. Install remaining brine valve assembly into
elbow using Teon tape or Teon paste, and set oat to minimum salt level see Specication Table for settings.
Place brine valve into brine well. Brine valve assembly will not sit on bottom of brine tank.
4. Connect the brine valve to the brine injector. Open the manual injector feed water valve and allow the brine tank
to ll with water. To speed this process the tank can be lled with a garden hose to about 2” below the platform.
The tank will continue to ll until the oat rises and shuts of the ow (approximately 1” above the platform).
Note: In the process of making brine for the rst regeneration, the solution volume will increase (one gallon of wa-
ter will be 1.2 gallons of brine). The nal level of the liquid will be several inches above the platform.
5. If the rell water shuts o󰀨 below the platform or too far above the platform, the brine valve should be removed and
the oat adjusted up or down until is shuts o󰀨 approximately 1” above the platform. Place the brine well cap seal
in place and open the manual valve in the brine line to the softener tank.

START-UP INSTRUCTIONS
Before proceeding to start-up:
• Make sure the unit is properly installed with all piping complete
• All of the required media has been properly loaded in the tank
• Read the controls section located in this manual
• Do not ll Brine Tank with salt
With all piping and installation completed, and with the mineral in the tank, proceed as follows:
1. Open the manual by-pass valve. The manual inlet and outlet valves are to remain closed.
2. Connect the power to the MX III controller. The controller display window will light up.
3. Verify the following and change if required.
SYSTEM 4 is displayed in the window for single systems
The K FACTOR is correct for your unit size - (metered units only)
4. Open the cover of the enclosure and manually rotate the stager to the #1 (BACKWASH) position. The stager mo-
tor will rotate back to the #4 (SERVICE) position. This is done to conrm the controller’s homing signal is opera-
tional.
5. Press and hold the EXTRA CYCLE button on the front of the controller. This will advance Unit 1 to the backwash
step. The Unit 1 stager should rotate to the step 1 (BACKWASH) position.
6. Slowly open the softener’s manual inlet supply valve. Do not open fully. Full ow of water could cause loss of me-
dia. Continue to ll slowly until all air is expelled and only water ows to the drain. Water will enter from the bottom
of the resin tank as air is expelled from the top drain. If the system is supplied with an air vent make sure that the
valve is open during this process.
7. When only water ows to the drain and out the air vent (if applicable), open the manual inlet valve all of the way.
Backwash until the water looks clean when caught in a container.

VOLUME REAMINING/BATCH CALCULATION
HOW TO CALCULATE SOFTENER’S TREATED WATER CAPACITY
“Batch size” is the term used for the amount of water passing through and being softened by the water softener be-
tween regenerations. This is a simple calculation provided two pieces of information are known:
• Size of the water softener in grains (i.e. MR-600 has 600,000 grains capacity per tank).
• Hardness of the raw water being treated by the water softener.
SAMPLE CALCULATION
Example:
MR-600-2 – Total capacity available is 600,000 grains. Water hardness is 20 grains per gallon.
BATCH SIZE
Batch size = Grain capacity of softener divided by grains per gallon of hardness
BATCH SIZE EQUATION:
Capacity of Softener (grains)
Batch Size = Hardness of Water (grains per gallon)
Capacity of Softener = 600,000 grains
Water Hardness = 20 grains per gallon
Unit is a model MR -600 softener
The hardness of the water was measured to be 20 grains per gallon
Using our equation take 600,000 ÷ 20 = 30,000 gallons.
For immediate regeneration type meter control the meter setting would be at 30,000 gallons. Commonly this value is
adjusted to 90 percent of the actual value (in this example 27,000 gallons) to assure not over-running the softener.
10% Safety factor - reserve capacity = 3,00 gallons.
30,000 gallons – 3,000 gallons = 27,000 gallons (batch size/volume remaining)

GENERAL SOFTENER OPERATION
Hard water passes through the valve manifold into the top of the softener tank. It ows downward through the mineral
bed and out through the bottom of the tank to service. As the water passes through the mineral bed, the hardness
present is removed through the process of ion exchange and at the same time sediment present is removed by
ltration action of the mineral. Once the mineral has extracted all the hardness it can, it must be regenerated and have
its capacity restored by the following procedure:
SERVICE
1. Service – Hard water enters the softener, is treated and exits the system.
REGENERATION
2. Backwash: The ow through the mineral bed is reversed and allowed to ow to drain. The up-ow action washes
any sediment or foreign material collected in the unit out to drain. At the same time the mineral itself is restratied,
thereby eliminating any possibility of channeling (approximately 10 minutes).
3. Brine Draw: The ow through the unit is returned to down-ow to drain at a slow controlled rate and during the rst
stage of this step the brine is injected to react with the mineral and restore its softening capacity (approximately
20 minutes).
4. Slow Rinse: The ow through the unit is a slow ow of water to rinse all of the exchanged hardness and salt from
the unit (approximately 40 minutes).
5. Fast Flush: The downward ow to drain in this step is increased to a high rate which will repack the mineral bed
and remove the last traces of salt and hardness from the regenerated equipment just before its return to service
(approximately 6 minutes)
HOW THE STAGER FUNCTIONS
The regeneration of the equipment provided is carried out through the redirection of ow through the valve manifold.
This manifold consists of individual diaphragm valves, which are controlled by the hydraulic stager mounted at the
bottom of the stager controller. The stager applies or relieves water pressure to close or open valves as required.
When water pressure is applied to the top of a diaphragm valve, it forces a diaphragm in causing it to close the seat
assembly. When pressure is relieved from the top of the valve, by venting it to drain through the stager, the water
pressure under the diaphragm forces it out thereby opening the seat assembly.
Note: If stager somehow gets out of sequence either:
• Rotate thumb wheel in direction of arrow.
• Be patient, unit will return to service position and be in sequence within 2 hours.

BRINE MAKER OPERATION
The brine-maker is an automatic brining system, which is easily
adjusted to provide maximum operating e󰀩ciency of your water
softener. It is a combination salt storage and brine-measuring tank
complete with an automatic valve.
The brine-maker consists of:
1. An open brine tank with a platform dividing it into sections:
• The upper section is used for dry salt storage
• The lower section for brine storage.
2. An automatic brine valve which is housed in a closed tube or “well”.
After each regeneration, water ows from the brine valve and into the
brine tank. When the water level rises slightly above the platform, a
oat closes the automatic brine valve. Salt slowly dissolves to form
concentrated brine. As brine is formed, the liquid volume increases
and the level rises in the salt. The resulting level may be 2 to 10 inches
above the platform depending on the amount of salt for regeneration.
During regeneration, the brine injector creates suction, which opens
the brine valve and draws into the softener tank. When the brine level
falls below the brine valve, the valve seats and prevents air from
entering the system.
RECOMMENDED TYPES OF SALT
Only puried salt should be used in the brining system. Palletized salt (“Button”, “Nugget”, and “Pellet”) or block salt
(free binders) is recommended. Do not use granulated salt, as it will fall through the platform screen.
Rock salt is not normally recommended. Most rock salt contains sludge-forming insoluble that collect on the platform
and prevents proper salt-water contact.
Only salt containing 0.5% or less of insolubles will provide continued satisfactory operation. If, salt with more insolu-
bles is used, the brine maker will require periodic cleaning.
MINIMUM SALTING ADJUSTMENT
Minimum salting is the most e󰀩cient use of salt. But it does minimize the capacity of
the unit, which will decrease the time between regenerations. Only make this adjust-
ment after the unit has completed a brine tank rell step and the water level was
checked to be above the salt platform. Follow these instructions to adjust your unit to
regenerate with minimum salt usage.
• Adjust brine tank rell time to the minimum setting according to the
specication table. Refer to the “Setting the regeneration cycle timer page.
• Monitor the water daily for hardness. It may also be necessary to adjust the
regeneration frequency, since the capacity of the unit has changed.
1. Remove brine valve assembly from brine well.
2. Remove air check from assembly.
3. Shorten the riser tube by removing the top extension pipe.
4. Reassemble brine valve assembly.
5. Reinstall the assembly into the brine well. The assembly will no longer reach the
bottom of the brine tank.

Meter/sensor input is required on each tank. Unit #1 will begin In Service with #2, #3, and #4 (if installed) will begin in Standby. At least one unit is In Service at all times. When ow rate to the Primary Service Unit increases to a user specied rate, the next unit in sequence will move from Standby to Service. As the ow rate falls below the user specied rate subsequent tanks will return to Standby. When the Primary Service Unit regenerates, the next unit in sequence will become the new Primary Service Unit. As each units capacity is reached the controller will initiate a Regeneration of that unit. Depending on the number of units in the system, and ow rate demand the regenerated unit will then be placed either into Standby or Service. Only one unit will be in Regeneration at a time.
