2. Water Softener Basics
What is hard water and how it is softened
The majority of water comes from groundwater sources. Rain water permeates layers of soil, clay, sand
and rock and in the process picks up a number of minerals along the way.
Hardness is dened by the content of calcium and magnesium that is found in water. The harder the
water the more calcium and magnesium it contains. Although it is not toxic, hardness can cause a
number of problems.
Hard water leaves traces of calcium and magnesium on glassware, surfaces, within pipework and
appliances.
Which causes:
• Shorter equipment life span
• Higher energy costs
• Reduced ow rates
• Under-performing appliances
Excess deposits create a drop in efciency, increased chemical cleaning costs and maintenance schedules
and in the worse cases equipment failure.
Iron is a common water problem. The chemical/physical nature of iron found in natural water supplies is
exhibited in four general types:
1. Dissolved Iron - Also called ferrous or ‘clear water’ iron. Dissolved iron is soluble in water and is
detected by taking a sample of the water to be treated in a clear glass. The water in the glass is initially
clear, but on standing exposed to the air, it may gradually turn cloudy or colored as it oxidizes. This type
of iron can be removed from the water by the same ion exchange principle that removes the hardness
elements, calcium and magnesium.
2. Particulate Iron - Also called ferric or colloidal iron. This type of iron is an undissolved particle of iron. A
ltering treatment will be required to remove this type of iron. A softener will remove larger particles,
but the particles may not be washed out in regeneration effectively and will eventually foul the ion
exchange resin.
3. Organic bound Iron -This type of iron is strongly attached to an organic compound in the water. The ion
exchange process alone cannot break this bond down and the softener will not remove this type of iron.
4. Bacterial Iron-This type of iron is protected inside a bacteria cell. Like the organic bound iron, it is not
removed by a water softener.
It’s important that when a softener is removing both hardness and dissolved iron, it must regenerate
more frequently than it normally would for just hardness. Many factors and formulas have been used to
determine this frequency. It is recommended that the softener be regenerated when it has reached 50-75%
of the calculated hardness capacity. This will minimise the potential for bed fouling.
When operating a softener on water with less than the maximum of dissolved iron, regular cleaning should
be performed. Clean every six months or more often if iron appears in your conditioned water supply. Use
resin bed cleaning compounds carefully following the directions on the container.
DO NOT USE WATER THAT IS MICROBIOLOGICALLY UNSAFE
OR THE WATER IS OF UNKNOWN QUALITY. THE WATER MUST
BE DISINFECTED BEFORE OR AFTER THE UNIT.

6. Pre-Installation
Instructions
Contact your local distributor to have a complete water analysis and check your water hardness from the
water supplier, this will keep your softener in proper working order.
YOU MUST FOLLOW ALL NATIONAL AND LOCAL AUTHORITY CODES AND
REGULATIONS GOVERNING THE INSTALLATION OF THESE DEVICES.
NOTE
Installation Instructions
Determine the correct location of the water conditioning equipment
Select the location of your softener with care. Review the various conditions below to determine a proper
location:
1. Locate as close as possible to the water supply source.
2. Locate on a at stabel surface.
3. Locate in correct relationship to other water conditioning equipment. (See diagram above ).
4. Softener should be located in the supply line before the water heater. Temperatures above
38oC damage softeners.
5. Do not install a softener in a location where freezing temperatures occur. Freezing may cause
permanent damage to this type of equipment and will void the factory warranty.
6. Allow sufcient space around the unit for easy servicing.
7. Determine if additional plumbing is required if your water source is a community water supply,
a public water supply or you wish to bypass water used for a geothermal heat pump, lawn
sprinkling, out-buildings or other high demand applications, refer to Fig. 1) .
8. Keep the softener out of direct sunlight. Heat build up from direct sunlight may soften and
distort plastic parts.

3. Use copper, brass, or PEX pipe and ttings.
4. Some codes may also allow PVC plastic pipe. Refer to local codes.
5. Always install the included bypass valve, or 3 shut-off valves. Bypass valves let you turn off water to
the softener for repairs.
6. 5/8” OD drain line is needed for the drain.
THE WASTE CONNECTION OR DRAIN OUTLET SHALL BE DESIGNED
AND CONSTRUCTED TO PROVIDE AN AIR-GAP TO THE SANITARY
WASTE SYSTEM OF 2 PIPE DIAMETERS OR 1 INCH(25MM).
(WHICHEVER IS LARGER)
NEVER INSERT THE DRAIN LINE DIRECTLY INTO A DRAIN, SEWER
LINE, OR TRAP. ALWAYS ALLOW AN AIR GAP BETWEEN THE DRAIN
LINE AND THE WASTE WATER. THIS WILL PREVENT THE POSSIBILITY
OF SEWAGE BEING BACK-SIPHONED INTO THE SOFTENER.

7. Water Bypass
For softener maintenance, you can isolate your water softener from the water supply using the bypass
valve located at the back of the control. In normal operation the bypass is open with the ON/OFF knobs
in line with the INLET and OUTLET pipes. To isolate the softener, simply rotate the knobs to the BYPASS
position.
You can use your water related xtures and appliances as the water supply is bypassing the softener.
However, the water you use will be hard. To resume treated service, open the bypass valve by rotating
the knobs to SERVICE position.
Please make sure bypass knobs are completely open otherwise the untreated water could bypass
through the valve.
Please make sure bypass knobs are completely open otherwise

Operation During a Power Failure
In the event of a power failure, the valve will keep track of the time and day. The programmed settings
are stored in a non-volatile memory and will not be lost during a power failure. If power fails while the
unit is in regeneration, the valve will nish regeneration from the point it is at once power is restored. If
the valve misses a scheduled regeneration due to a power failure, it will queue a regeneration at the next
regeneration time once power is restored.

5. Slowly open the inlet knob on the bypass valve with the bypass tool supplied and allow water to enter
the unit. Allow all air to escape from the unit before turning the bypass fully open. Then allow water
to run to drain for 3-4 minutes or until all media nes are washed out of the softener indicated by
clear water in the drain hose. Open a cold soft water tap nearby and let water run a few minutes or
until the system is free of foreign material resulting from plumbing work. Close the water tap when
water runs clean.
6. Press any button to advance to the BRINE position, when it arrives, press any key to skip the BRINE

CAUTION
Automatic Raw Water Bypass During Regeneration
The regeneration cycle can last 60 minutes after which softened water service will be restored. During
regeneration, raw water is automatically bypassed. Hot water should be used as little as possible during this
time to prevent raw water from lling the water heater. This is why automatic regeneration is set for a convenient
during the night and manual regenerations should be performed when little or no water will be required.

17
16
SpectrumTM
Check the Salt Level
Check the salt level monthly. Remove the lid from the cabinet or brine tank, make sure salt level is always
above the brine level.
Adding Salt
Use only clean salt labeled for water softener use, such as crystal, pellet or nugget. The use of rock salt is
discouraged because it contains insoluble silt and sand which builds up in the brine tank and can cause
problems with the system operation. Add the salt directly to the tank, lling no higher than the top of the
brine well.
Bridging
Humidity or the wrong type of salt may create a cavity between the water and the salt. This action, known
as ‘bridging’: prevents the brine solution from being made, leading to your water supply being hard.
If you suspect salt bridging, carefully knock on the outside of the plastic cabinet or pour some warm
water over the salt to break up the bridge. This should always be followed up by allowing the unit to use
up any remaining salt and then thoroughly cleaning out the cabinet. Allow four hours to produce a brine
solution, then manually regenerate the softener.
Resin Cleaner
An approved resin cleaner must be used on a regular basis if your water supply contains iron. The
amount of resin cleaner and frequency of use is determined by the quantity of iron in your water(consult
your local representative or follow the directions on the resin cleaner package).
Care of Your Water Softener
To retain the attractive appearance of your new water softener, clean occasionally with a mild soap
solution. Do not use abrasive cleaners, ammonia or solvents. Never subject your softener to freezing.
