INTRODUCTION
This booklet is designed to cover the Waterco Ezysoft semi automatic domestic water softeners.
1. GENERAL INFORMATION
1.2. WATER SOFTENERS
Hard water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe).
Removal of these mineral is accomplished by softening the water through an ion exchange process.
As the water ows through the mineral tank, the dissolved minerals become attached to the resin,
creating soft water. Over a period of time the resin will become exhausted, and the softener will be
regenerated using a brine solution produced from the salt in the brine compartment.
1.3. ADVANTAGES OF USING EZYSOFT
Extended appliance and equipment life
The minerals found in hard water can build up on the insides of appliances such as washing
machines, dishwashers and water heaters, reducing their working life and decreasing efciency.
Ezysoft not only extends their lifespan but also benets the environment by reducing waste and
conserving the raw materials and energy used in manufacturing.
Faster water heating
Hot water heaters can heat softened water more quickly than hard water, improving efciency by
roughly 22 per cent for electric water heaters and 29 per cent for gas-powered units. Improving
efciency with Ezysoft reduces energy consumption, resulting in signicantly lower energy bills.
Cleaner plumbing system
Hard water leaves scaly deposits in plumbing xtures and pipes, which can corrode and shorten
the life of your home’s plumbing system as they build up over time. Reducing mineral deposits with
Ezysoft helps eliminate the adverse effects of clogs and corrosion, extending the life of the plumbing
system and helping appliances and equipment operate more effectively.
1.4. KEY FEATURES
Environmentally friendly
Discharges to the environment are minimal – the regeneration is performance using a low ratio salt/
resin when compare with the standard resins. The quantity of salt used in Ezysoft per regeneration is
up to 50% less than the standard water softener without sacricing the capacity.
Easy to use
The regeneration of the softener starts by just a twist. Ezysoft is also more efcient because it uses
a resin with beads of uniform size that increases its operating capacity when compare with the
standard resins. Also, Ezysoft does not require electricity.

2. OPERATING CONDITIONS AND REQUIREMENTS
• OPERATING PRESSURE: min. 140 / max. 830 kPa
− This system is congured to perform optimally at an operating pressure of 300 kPa (±50
kPa); in case of a lower or higher operating pressure the performance may be affected
negatively.
− Check water pressure regularly.
− Take into account that night time water pressure may be considerably higher than day time
water pressure.
− Install a pressure reducer ahead of the water softener if necessary.
• OPERATING TEMPERATURE: min. 2°C / max. 48 °C
− Do not install the water softener in an environment where high ambient temperatures (e.g.
unvented boiler house) or freezing temperatures can occur.
− The water softener cannot be exposed to outdoor elements, such as direct sunlight or
atmospheric precipitation.
− Do not install the water softener too close to a water heater; keep at least 3 meters of
piping between the outlet of the water softener and the inlet of the water heater; water
heaters can sometimes transmit heat back down the cold pipe into the control valve; always
install a check valve at the outlet of the water softener.

Waterco Commandomatic Ezysoft

3. HOW THE SYSTEM WORKS
The Commandomatic Ezysoft is a semi-automatic water softener. When the drain paddle is opened,
the valve is automatically transferred to the regeneration position; with its few moving parts, this
simple and reliable system guarantees years of trouble-free service.
The semi-automatic twist timer must be manually initiated by simply turning the knob to the desired
brine/slow rinse cycle time; the regeneration will take place and afterwards the valve will automatically
return to the service position. The valve is designed for hard water bypass during regeneration.
The regeneration sequence is followed:
I. SERVICE:
Untreated water ows down through the resin bed and up through the riser tube; the water is
conditioned when passing through the resin.
II. BRINE:
Salt brine, drawn from the brine tank by the injector, ows down through the riser tube and
slowly up through the resin bed to drain; the resin is being regenerated when the salt brine
passes through. The brine cycle is terminated when the air check is shut.
III. SLOW RINSE:
Slow rinse continues for the remainder of the brine cycle; the injectors motive water ows down
through the riser tube and slowly up through the resin bed to drain, slowly washing the brine
from the resin tank.

4. INSTALLATION
To facilitate the installation process, remove the salt lid and main cover from the water softener.
4.2. CONNECTING INLET & OUTLET
I. Screw the factory bypass onto the elbow connections of the water softener (2&3); make
sure to install the gasket seals. Tighten the nuts rmly by hand.
II. Screw the connection kit with nuts onto the factory bypass (1&4); make sure to install the
gasket seals. Tighten the nuts rmly by hand.
III. Connect the mains water supply to the nipple on the inlet port of the factory bypass (1).
IV. Connect the house/application to the nipple on the outlet port of the factory bypass (4).
1 = mains water supply (untreated water)
2 = inlet of water softener (untreated water)
3 = outlet of water softener (treated water)
4 = house/application (treated water)
Figure 1 Factory Bypass
In multiple installations, filters are always installed upstream of softeners.
• It is recommended the use of flexible hoses to connect the water softener to the water
distribution system; use hoses with a large diameter in order to limit the pressure loss.
• If the water softener is not equipped with the factory bypass, it is recommended to install
a 3-valve bypass system (not included with this product!) to isolate the water softener from
the water distribution system in case of repairs. It allows turning off the water to the water
softener, while maintaining (untreated) water supply to the user.

Waterco Commandomatic Ezysoft
I pg 07
4.3. THE DRAIN
I. Connect a 13 mm hose to the drain of the control
valve (1); secure it by means of a clamp.
II. Run the drain hose to the sewerage system and
connect it to the stand pipe assuring sufcient air
gap. This drain line operates under pressure, so it
may be installed higher than the water softener.
III. Connect a 13 mm hose to the overow elbow,
located at the back side of the water softener;
secure it by means of a clamp.
IV. Run the drain hose to the sewerage system and
connect it to the stand pipe assuring sufcient
air gap. This drain line does NOT operate under
pressure, so it may NOT be installed higher than
the water softener.
Notes:
• It is recommended the use of a stand pipe with
air trap.
• To prevent backflow from the sewerage system
into the water softener, always make sure to have
an air gap between the end of the drain hose and
the sewerage system itself; as a rule of thumb,
the air gap should be minimum 2x the diameter
of the drain hose.
• Always use separate drain hoses for the control
valve (evacuation of rinse water) and the softener
cabinet’s overflow.
• Lay-out the drain hoses in such a way that
pressure loss is minimized; avoid kinks and
unnecessary elevations.
• Make sure that the sewerage system is suitable
for the rinse water flow rate of the water softener.

Figure 3 Drain Hose Installation

5. START UP
When installation has been completed, the unit is ready to be placed into service. Proceed as
follows, while checking the unit for any leakages:
I. Place unit in bypass and turn on main water supply; open a cold water tap nearby and
allow water to run for a few minutes until all foreign material that may have resulted from the
installation is washed out; close the tap.
II. Slowly shift the bypass valve to the service position and secure it; allow water to completely
ll the resin tank.
III. Carefully open a cold water tap and allow water to run for at least 2 minutes to set the resin
bed and purge air from the system; close the tap.
IV. Fill the brine tank with water, higher than the air-check level.
V. Turn the timer knob clockwise past 30 min, to open the drain paddle; the valve is now
transferred to the brine/slow rinse position.
VI. Allow the valve to draw water from the brine tank until the air check closes.
VII. Place unit in bypass.
VIII.Add the appropriate amount of water to the brine tank.
IX. Add salt to the brine tank.
X. Shift bypass valve back to the service position.
XI. Turn the timer knob back counter clockwise to the OFF position, to close the drain paddle;
the valve is now transferred back to the service position.
5.1. ADJUSTING RESIDUAL HARDNESS WITH FACTORY BYPASS
I. Adjust the residual hardness of the water that leaves the softener, by means of the adjusting
screw, incorporated in the ‘outlet’ valve of the factory bypass:
• To raise the residual hardness: turn the screw counter clockwise; usually 1 turn corresponds
to a residual hardness of ± 40mg/L, 2 turns to ± 80 mg/L.
• To reduce the residual hardness: turn the screw clockwise.
Figure 4 Adjusting Residual Hardness

Waterco Commandomatic Ezysoft
I pg 09
6. INITIATE A REGENERATION
The semi-automatic timer must be manually initiated; by turning the timer knob clockwise past 30
min, the drain paddle is opened and the valve is transferred to the brine/slow rinse position; the
length of this cycle can then be set between 0 and 120 min. At any time the regeneration can be
cancelled by turning the timer knob back counter clockwise to the OFF position.
The regeneration time required by the Ezysoft is 115 minutes
Notes:
• If the pressure is low the unit may take longer than the recommended regeneration
time.
• The salt used for regeneration passes through the resin bed and out to the drain. It is
not strong enough to harm a septic tank and will not affect the bacterial action, which
takes place.
• These units are not designed for the removal of micro organisms and may result in
the accumulation of micro organisms. It is therefore important that filters are used on
microbiologically safe water and that flushing and maintenance protocols are strictly
adhered to.
7. WHEN TO REGENERATE
It is advisable to regenerate your water softener on a regular basis. The frequency of regeneration
will vary according to the amount of water being used and its hardness. Find out the approximate
hardness of the water supply in question, this can usually be obtained from the local Water Authority.
The following chart details the capacity of each unit based on the harness of the water. To nd the
frequency of regeneration, divide the capacity of the unit by the calculated daily usage rate.
HARDNESS mg/L
CaCO3

Table1.
UNIT CAPACITY CHART
FOR COMMANDOMATIC
EZYSOFT MODEL

A calculation can be made to estimate usage, to enable a regeneration schedule to be prepared.
Each person will use approximately 125 litres of water per day. An automatic washing machine and/
or dishwasher each counts as an additional user.
Example:
Calculate the days between regeneration for a family of 5 members. The family owns a washing
machine and a dishwasher. Hardness of supply line is 140 mg/L CaCO3.
Family members: 5
Dishwasher
Washing Machine
Total family member for calculation: 5 + Washing Machine + Dishwasher = 7
Total Estimated Water Usage (Daily) = 7 x 125 litres /day = 875 litres/day
Days to Regeneration = = 9.8 Days
The regeneration should be done every 10 days.
Calculate the total Hardness.
Usually chemical analyses report Calcium (Ca) and Magnesium in terms of parts per million (ppm)
as Calcium Carbonate (CaCO3). However, in some cases, the analysis is reported in terms of the
elements themselves. If this is the case, proceed as follow:
Calcium (as Ca)_______x 2.50 = _______ppm Ca as CaCO3 (A)
Magnesium (as Mg)_______x 4.10 =_______ppm Mg as CaCO3(B)
(A)_______ + (B) _______ = _______ Total Hardness ppm as CaCO3
Days to Regeneration = Capacity (hardness)

8. MAINTENANCE
8.2. BYPASSING THE WATER SOFTENER
Occasionally it may be necessary to put the unit hydraulically in bypass, i.e. to isolate it from the
water distribution system; e.g.:
• in case of an urgent technical problem;
• when it needs to be removed for maintenance;
• When it is not necessary to supply treated water to the house/application (rell swimming
pool, irrigation, etc).
BYPASS POSITION

MAINTENANCE POSITION
1 = inlet valve to water softener is OPEN
2 = outlet valve from water softener is CLOSED
Figure 7 Maintenance Position
I pg 11

8.3. ADDING SALT
Be sure to use Commandomatic salt (approximately 1/4” pellets), as it is specially selected large
granule salt, graded for maximum efciency and packed in 25kg moisture proof bags. This will
prevent “bridging”, as would occur if ne salt were used. Your brine tank holds 50kg – or 2 bags of
salt. When salt level drops to approx. half the depth of the brine tank, add another bag of salt.
The water softener needs ‘brine’ for its periodic regenerations. This brine solution is made from
water that is automatically dosed in the brine cabinet by the control valve, and water conditioner salt.
The user should make sure that the brine cabinet is always kept full of water conditioner salt.
Therefore he should periodically check the salt level inside the brine cabinet and rell it if necessary.
To open the salt lid, simply take it by the handle and lift it. The salt lid can be removed completely
to facilitate relling.
8.4. BRINE CABINET
To retain the appearance of the water softener, simply wipe it with a damp cloth or clean it with a mild
soap solution; never use abrasive cleaners, ammonia or solvents.
9. PARTS REPLACEMENT
!!! BEFORE SERVICING:
• Make Sure The Control Valve Is In Service Position
• Bypass Or Disconnect The Water Supply
• Relief The Water Pressure
9.1. TIMER HEAD ASSEMBLY
I. Remove the drain hose from the drain line tting.
II. Remove the 4 timer head screws and pull away the timer head assembly.
III. Reverse the procedure for reassembly; make sure the drain port O-ring is securely installed
in the valve body groove.
Figure 8 Adding Salt
Ideally the level of water conditioner salt inside the brine
cabinet is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufcient brine saturation,
resulting in a loss of softening capacity. A higher level of
water conditioner salt can cause salt bridging (hard crust
or salt bridges in the brine cabinet). When you suspect
salt bridging:
I. Carefully pound on the outside of the brine
cabinet to break loose the salt bridges;
II. Using a broom (or like blunt tool) carefully push
the salt to break it apart;
III. Pour warm water over the top of the salt to
dissolve it.

DRAIN FLOW ADJUSTER
!!! ATTENTION
When the valve is equipped with an
incorporated drain ow control (optional),
the drain ow adjuster is When the valve is
equipped with an incorporated drain ow
control (optional), the drain ow adjuster
is assembled and locked in the wide open
position! By releasing the locking screw of
the locking plate, the drain ow adjuster can
still be used, but note that the maximum
ow to drain is limited by the incorporated
drain ow control (optional).
With the drain ow adjuster it is possible to adjust the water ow to drain during regeneration. The
so created counter pressure helps to keep the piston of the valve in the regeneration position when
the operating pressure is extremely low (< 1,5 bar). To adjust:
1. Place the unit in brine/slow rinse position.
2. Turn the drain ow adjuster either to the right or to the left until the piston remains stable in the
regeneration position.
Do note that closing the drain ow adjuster too much, will result in bad suction of the injector.
FAST FUNCTIONING CHECK
When You want to check if the system is operating correctly, proceed as follows:
1. Open water supply to valve.
2. Turn the timer knob clockwise past 30 min, to open the drain paddle; the valve is now transferred
to the brine/slow rinse position.
3. Check brine draw by listening or feeling for suction.
4. Turn the timer knob back counter clockwise to the OFF position, to close the drain paddle; the
valve is now transferred back to the service position.
